- Billbergia pyramidalis
Or the search for the totally red petalled form
It must have been in the mid 1980’s that I acquired Smith and Downs Monograph (1979) on Bromelioideae and as is usual when I get a book of this nature I read it from cover to cover. One thing that did intrigue me was Billbergia pyramidalis where I had two forms. One was dark-green narrow leaved(01a & b) and the other pale-green wide leaved.(02a, b &c) I was assured by those more learned than I that the wide-leaved form was called var. concolor which I assumed had something to do with the leaves. However, pages 2007 to 2010 in the Monograph told me different. I should be looking for totally-red-petals. When my narrow-leaved Billbergia pyramidalis flowered there were clearly violetish tips on the inside of the petals. When my wide-leaved plants flowered I thought they had totally red petals. But, when the petals opened there was this tell-tale violetish tipping albeit pale. I continued my search for a totally red-petalled Billbergia pyramidalis grumbling to myself all the time because I could never find one.
It must have been about 1990 that I started to correspond with Don Beadle, the US Mr. Billbergia, and he said he had never found a totally-red-petalled Billbergia pyramidalis either! My estimation of Don went up and up with this comment! Clearly, here was another observant fellow! But we got no further.
In March 1999 I got a request on the Internet from a chap who wanted to use copies of a photo we had on http://fcbs.org for his Web site and which he wanted to call the Summer Torch! I gave him authority but suggested he use the correct botanical name of Billbergia pyramidalis var. concolor. My use of the word ‘correct’ kept bugging me so now you know why I am writing this!
Lyman Smith (1954) decided to name a variety of Billbergia pyramidalis as ‘concolor’, basing his decision on a plant whose heritage could be traced back 100 years and was then owned by David Barry Jnr. This is now a herbarium specimen so we will not be able to check the petal colour! Forever the Doubting Thomas I wonder if the petals were totally red. In fact there has been no sightings of this rare totally-red-petalled Billbergia from California. In the 1960’s plants came to Australia from David Barry but not this one. David Barry’s nursery was acquired by Shelldance Nursery which in turn was acquired by the Singapore Botanic Gardens in 1994. When I paid an official visit to the Singapore Botanic Gardens in June 2001 I could find no trace of the plant there. In Bromelia (The Brazilian Journal) June 1995 p24 Elton Leme said ” The blue colour of the petal tip is very faint and often difficult to discern........ Nothing is known of the geographic origins of var. concolor, but the type variety grows on the ground of the Atlantic forest, on mountain slopes, especially in Rio de Janeiro.”
It all started in 1815 when Sims named a Bromelia pyramidalis.(03) This is so long ago that some ‘s’s were printed as ‘f’s but I won’t reproduce them here!
“BROMELIA pyramidalis;
In our specimen, the scape did not rise so as to elevate the flowers above the bracts, perhaps from a deficiency of heat: in which flowered earlier, the spike was more lax, and the flowers , after deflorescence, became patent; calyx, corolla, and stamens, persistent.
This plant, like some others, both in this genus and in Tillandsia, holds a quantity of water in the bottom of the leaves; which, it has been asserted, they are never found without, even in the hottest weather, in a tropical country.
Communicated by the lady of the Right Hon. George Rose, from Cuffnells, where it flowered two successive years, in February and March. The mother plant was received from Rio de Janeiro some years ago, and threw off several offsets before it flowered, which have been treated the same as the pineapple, till of a good size for flowering, when the pot was taken out of the bark and placed upon the shelf in the stove.” The botanical drawing that accompanied the description, while not a good one, clearly equates with the description.
In 1830 Martius named Billbergia thyrsoidea and I quote his comments on its difference from Billbergia pyramidalis.
“Differs from B. pyramidalis to which it has a good affinity, chiefly in
Leaves large erect, much wider, shorter, obtuse with a tip, equally concave,
Spines strong,
Spike larger,
Scape bracts light red short acuminate, less nerved,
Smaller stature,
Collected by Martius near Rio Janeiro on rocks.”
John Lindley (1852/3) describes Billbergia thyrsoidea without specific reference to petal colour but was used by Lyman Smith for his var. concolor. I quote:
“Such are the characteristic marks of this very beautiful stove plant, originally found by Martius on rocks near Rio Janeiro, and imported by M. de Jonge of Brussels. For the opportunity of figuring it we are indebted to Mr. Henderson, of the Wellington Nursery, St John’s Wood. It requires to be managed in the same way as a Pine Apple.
It is most nearly allied to the Pyramidal Billbergia figured in the Botanical Magazine, t. 1732, and in the Botanical Register, t. 203 and 1181; but that plant has glaucous taper-pointed leaves, and very large spreading flowers, conspicuous for the white mealiness of the calyx.”
In 1853 in Curtis Magazine plate 4756 shows Billbergia thyrsoidea (04)with totally red petals. A photograph of this plate is in JBS 1991 Vol 41 #3 p104 but this should have been referenced as Billbergia pyramidalis (Sims) Lindl. var. concolor L B Smith not Billbergia pyramidalis (Sims) Lindley.
Billbergia thyrsoidea in Curtis Bot. Mag Plate 4756 1853
“A richly coloured and very handsome Bromeliaceous plant, native of Brazil, presented to our garden by Messrs. Henderson, of the nursery, St John’s Wood, under the name here retained, and which accords with the species so called by Martius, which he found growing in rocky places about Rio Janeiro. It is quite different from Billbergia pyramidalis, and every other with which we are acquainted. Our readers will observe, that, though the leaves grow erect, or nearly so, on the living plant, our figure of the leaf represents it bent back, to enable us to bring an entire one into the plate. It requires the heat of the stove, and flowered with us in November of the present year, 1853.”
Clearly the articles in 1852/3 and in 1853 were talking about the same plant because of the reference to a Mr Henderson and the latter article is more specific as to the red petals as well as the coloured plate but was not the article referred to by Lyman Smith! Both articles pointed out that Billbergia pyramidalis and Billbergia thyrsoidea were different and what is very revealing is the last paragraph of the Paxton Garden article where the differences were noted without reference to petal colour! This is in line with my interpretation of these two taxa. Baker in 1889 describes Billbergia thyrsoidea as petals bright red with a violet-purple tip and it was not until Mez 1935 that we see the reference to petals totally red! Clearly, botanists in the 1800’s were aware of, and could identify, this taxon without stressing the violet-blue shading to the petals. Lyman Smith decided that Mez’s comment that petals are totally red was incorrect because he placed Billbergia thyrsoidea Martius as a synonym of Billbergia pyramidalis var. pyramidalis. However, he then used Lindley 1852/3 plate 74 as his variety concolor relying purely on the artist’s interpretation and not what was written. He also used Barry’s plant for the type as being a PROBABLE clone of de Jonge. I maintain that ‘concolor’ based purely on petal color is a misnomer and I consider that a totally red-petalled Billbergia pyramidalis has never been in existence.
In my investigation of this species I did consider taking the splitter approach by resurrecting Billbergia thyrsoidea Martius and Billbergia pyramidalis var. bicolor Lindley (05a & b) but decided that this species is better treated as a single entity. Lyman Smith was clearly prepared to ignore the variation in leaf width and leaf tippings and this can be borne out in my experience by giving the plant different cultural conditions as well as sometimes having two different leaf shapes on the same plant. Various leaf shapes can also be obtained from offsets from the popular Billbergia ‘Kyoto’ (06). The difference in the density of trichome covering can also vary greatly. A prime example of this is in Aechmea fasciata.
We are then left with petal colouring where there are contrasts if we do not use Smith’s vague terminology of ‘towards the apex’. There are two botanical terms used to describe a petal, the blade which we can all easily see, and the claw which is mostly hidden by the sepals. It has been my experience that the blade colour can vary from red with pale violet tipping, to totally violet to totally dark violet. The claw can vary from white to cream to yellow to pinkish but I have been unable to link these colours with a particular blade colour. This variation suggests that there is no need for variety lutea Leme and Weber (1984) (07a & b) which I have also noticed varies in colour in cultivation, under ICBN rules because all can be accommodated by varying the description of Billbergia pyramidalis to read.

Type Sims Hortus sn. Description and plate
M B Foster (1960) described a Billbergia pyramidalis var. striata from a variegated seedling obtained from a batch of what he termed a winter flowering form of B. pyramidalis. At that time B. pyramidalis was considered to have red petals with bluish tips but not only did Foster’s plant flower at a different time but it had a total petal blade of a violet hue and a claw whitish. In fact it was closer to Billbergia pyramidalis var. bicolor Lindley than to B. pyramidalis (Sims) Lindley. The naming of B. pyramidalis var. striata was ignored by Smith & Downs in 1979 in their monograph and was only reintroduced in DeRebus I in 1994 without any comment. Foster’s B. pyramidalis var. striata will be covered under the ICNCP rules by renaming it Billbergia ‘Foster’s Striate’.
In more recent times we have seen one taxon named var. vernicosa by Pereira in 1979 which was relegated to var. pyramidalis . This was because ”In the original description B. pyramidalis var. vernicosa is described as having “brilliant leaves and flowers” but this appearance is produced by a chemical substance on the voucher specimen to avoid insect predation.”
Now I have convinced myself that there is one broad based species of Billbergia pyramidalis there are a few forms that should be covered as cultivars. If you believe there are others please advise the Registrar. It is difficult to trace what happened with cultivars so many years ago because so few coloured photographs exist and written descriptions were, in many cases very vague. We do know that in the late 1950’s, early 1960’s both Mulford Foster and Julian Nally grew many plants of Billbergia pyramidalis from seed and offset. We have been able to contact Bill Frase who worked for Mulford in this period and Eloise Beach who worked for Julian. What is interesting is that Foster describes his striations as white. Eloise Beach tells us that she found one plant in the many that Julian had, was albomarginated and which she called ‘Julian Nally’ and we have a photo of this. It is possible that this cultivar has since disappeared. In 1983 Don Beadle thought he had the true ‘Julian Nally’ which has petals predominantly red and should not be linked as a cultivar with the dark violet petalled Billbergia pyramidalis var. striata . This Beadle’s plant is still in circulation and will be recorded from now as ‘Julian Nally Beadle’
We now come to the next problem where the white variegations have changed to creamish yellow. This must have been gradual because our informants advise that as far as they can remember the plants being grown now are the same as those grown 40 years ago. So ‘Foster’s Striate’ will show yellow striations in our photos! And that’s not all. In certain situations the variegations will almost totally disappear and the leaves become almost totally yellow when they become ‘Gloria’
To recap, we have
‘Foster’s Striate’ This replaces the old Billbergia pyramidalis var. striata. (08a,b,c,d)
‘Gloria’ For the totally yellow leaf form (09a,b)
‘Julian Nally’ for the original albomarginate form, now thought extinct (10)
‘Julian Nally Beadle’ for the plant in Don Beadle’s listing 1983 (11)
‘Kyoto’ a variegated form possibly from Japan (12)
‘Lutea’ To replace the old var. lutea (13)
‘Pale Face’ Probably extinct. No photo held
