Bromelia landbeckii Lechl. ex Phil., Linnaea 33: 246 (1864-1865).
Vernacular name: Nocha (Philippi, 1864-65; Hoffmann and Flores, 1989).
Uses: The leaves are reported to be widely used in the weaving of handicrafts (baskets, ropes, mats etc.) due to being firm and durable, whereas Greigia sphacelata is unsuitable for this purpose (Philippi, 1864-I865).
Characteristics of this species include the large conspicuous leaf-sheaths, the long and firm but flexible leaves which unlike Greigia sphacelata bear much shorter spines only in the apical part. The inflorescence is distinctly pedunculate, whereas in G. sphacetata the scape is shorter and largely hidden by its bracts. The outer primary bracts are different from those in G. sphacelata being widely ovate, entire and ca equaling the flowers. nThe authorship of Bromelia landbeckii is still in doubt. On the printed labels of Lechler's specimens we find: "3098. Bromelia landbeckii Lechl. hb.:' We interpret the notation to refer the specimen to Lechler's herbarium, but it could also be interpreted to refer the name B. landbeckii to Lechler. Furthermore, the exact "publication" date of the herbarium labels remains unclear. Concluding from an announcement by Hohenacker (1883), they were probably issued in 1853.
In the past, Greigia landbeckii has often been confused with G. pearcei. Baker's (1889) description of G. landbeckii is actually based on specimens of both G landbeckii (Lechler 3098) and G. pearcei (Ochsenius s.n., Pearce 269). Consequently, some of the features described only match one of either of the two species. Even Krause who first collected Greigia pearcei seems to have been confused by the two species. Philippi (1864-65), in his protologue of Bromelia landbeckii, cites a remark by Krause saying that the described species is not identical with the plant usually called Nocha but that this name belonged to yet a fourth species-which very likely refers to G. pearcei. As explained below one mixed collection exists in SGO. The general appearance of Greigia landbeckii is distinctly different from that of G. pearcei. The former being much larger, with much wider, thicker and firmer leaf-sheaths and blades, longer spines, larger inflorescences. Though, in both species the primary bracts are entire.
According to Smith and Downs (I979) the holotype may be at SGO. To the best of our knowledge, SGO has three specimens considered as types for either Greigia pearcei or G. landbeckii. We have only seen the photos of these specimen. Only one of them seems to have been collected by Lechler, however, it does not carry a collectors number and is dated 1860. Therefore, this specimen is not regarded to be a duplicate of Lechler 3089 (hence not the holotype). The label reads "Bmmelia landbeckii. Lechler. Incolis Nocha. Ad originem Rio Futa legi. Januario 1860:' The specimen clearly belongs to Greigia pearcei and not to G. landbeckii. The second specimen is a mixed collection. It consists both of leaves and inflorescences from both G landbeckii and G. pearcei. It seems to be a collection of Krause with no collection number, and is not a type. The third specimen, Krause s.n.?, although labelled G. landbeckii, clearly belongs to G. pearcei. According to Harms {1930} G. landbeckii is closely related to G. sodiroana Mez.
Chile, region VIII and Chiloe in region X, 37°2S'5-42°03'5 (Fig. 1). According to Skottsberg (1916), Greigia landbeckii can be found as far south as Isla San Pedro, Chiloe, which would extend its range to ca. 43°20'S, but no specimen is cited. Occurrence of G. landbeckii is reported for Chiloe also by Donoso et al. (1985; Cordillera de San Pedro, 42°20'S) and Armesta and Rozzi (1989; Cordillera de Piuchue, 42°30'S). Its conservation status is "Vulnerable" (Hoffmann and Flores, 1989). The most recent collection dates from 1985 (Billiet 3736). —SeeHarvard Pap. Bot.
