By this time, I was almost sure that the plant in cultivation since the mid-1800s as "luddemannii" (collected near the habitat of C. bivittatus) was in fact C. marginatus. I took a blooming plant to Harry Luther during the Southwest Guild Show in Fort Worth, Texas (90 Cryptanthus exhibited). He agreed to study the plant.
He found the cultivated material I gave him to be Cryptanthus marginatus. Upon examining the photo of the Morren drawing of var. luddemannii, the back side of the leaves shows heavy scurfing. Based on the taxonomic description is should be considered a synonym for C. marginatus: Rereading the monograph I came upon Cryptanthus marginatus. (A rare plant ... I didn't know of very many growers who had it in their collection other than one Bob Whitman brought back from his last collecting trip in Brazil.) I thought it odd that no one had C. marginatus. Mulford and Racine Foster collected the plant near Santa Teresa, Espirito Santo, July 25, 1939 (bloomed May 14, 1941 ). Leaves about 12 . . . light green with a narrow reddish margin, the broad flat median stripe somewhat darker than the equally broad undulate marginal stripes.
This sounded like the plant I owned as "luddemannii". I went to the greenhouse. Several plants were just coming into bloom (the bivittatus certainly aren't blooming in my area right now). I selected a blooming plant and brought it in to examine under better light with a magnifying glass.
The monograph illustrated the unusual sepals of C. marginatus. I was excited as I discovered the blooming plant on my table demonstrated this unique characteristic. But I couldn't be sure. Was this the rare C. marginatus identified by Dr. Lyman B. Smith in 1955, or was it just a hybrid.
The following weekend I judged the Sooner State Bromeliad Study Group's Standard Show in Tulsa, Oklahoma. Over one third of the entries were Cryptanthus. No one entered a C. marginatus, "luddemannii" or "major", but I discussed my research with many of the Cryptanthus Society members present. Kathy Dorr told Bob Whitman she believed the name "major" had been "tacked on" in the 1950s by a large commercial bromeliad nursery in southern California. The association was logical at the time... shadegrown, the plant looked like a large C. bivittatus.. —See Smith & Downs 1979
