Lepismium miyagawae

Desc from protologue in CSJ (US) p63 1987

Plant - shrubby succulent epiphyte: first erect, later sprawling-pendent; laterally or basally branching.
- up to 100 cm long, fleshy-soft, 1.5 - 2 cm in diameter; mostly 3 angled, rarely 4 - 5 angled; only slightly subcrenate.
- about 1 - 2 cm distant from each other with very short white wool, up to 10 soft lateral bristles and 3 - 5 whitish spines up to 7 mm long.

Style - 10 mm long, white, with about 6 papillose white stigma lobes.
- about 9 mm in diameter, strongly tuberculate with numerous bristly areoles. Pericarp wall with abundance of large mucilage cells.
- whitish, rather small, globose-tuberculate, about 10 mm in diameter. Numerous areoles with ca. 10 soft spines up to 5 mm long. about 20 seeds per fruit, 1.7 mm long and 1 mm broad; testa light brown with convex cells and deeply depressed cell corners (cereoid testa type, not rhipsaloid)

DISTRIBUTION. This plant is only known from one collection by Mario Miyagawa on the 19 October 1974 in the yungas of Alto Beni, near Mataral (between Cochabamba and Santa Cruz, Dept. Cochabamba , Bolivia) at 600 m altitude.

The plant grows and flowers easily in cultivation.

This new species is rather unique and has no very close relatives. Its closest relatives we would consider to be Pfeiffera ianthothele (Monville) Weber and Acanthorhipsalis (Rhipsalis) monacantha (Griseb.) Britton and Rose. However, the new species represents probably the most ancestral type of all rhipsaloid taxa known resembling in many details even of Erdisia and Corryocactus.

The type locality of Pfeiffera miyagawae by Bauer in Cact Syst. Init. 20:9. 2005
When P. miyagawae was described (Barthlott & Rauh 1987) the quite large (for the genus) bright orange flowers, produced in abundance in very early spring, were a little sensation. The type locality, according to the finder, Mario Miyagawa, was given as: Bolivia; Cochabamba; yungas of Alto Beni, near Mataral, 600 m. Subsequent collectors have always failed to find the species at this locality and experienced field collectors have doubted that the locality data were correct (Barthlott, Krahn, pers. comm.; Ibisch, Kessler, Nowicki & Barthlott 2000). Climatic conditions suggest it would be most unlikely to find a plant like that there. It was not until 2003 that the problem was resolved, thanks - as so often with Bolivian epiphytic cacti - to Wolfgang Krahn. On 31 October 2003, along a dirt road in the dept. La Paz, prov. Sud Yungas, 7.7 km south of La Asunta at 750 m altitude, he found a second clone (Krahn 1044). Its long stems were hanging out of the tanks of a bromeliad colony and there was a single flower to confirm its identity. Living material is currently under observation in hort. Krahn, Dorsch and Bauer. When Krahn told me about his locality "La Asunta" I vaguely remembered having heard of this locality before, somehow in connection with Mario Miyagawa. My remembrance came back when Krahn showed me further collections from that area - five clones of Selenicereus inermis from two localities in dept. La Paz: Prov. Sud Yungas, c. 36 km N of Chulumani along the road to La Asunta, Totora Pampa, 900 m; 30 October 2003; Krahn 1040; prov. Sud Yungas, c. 50 km south of La Asunta, Tolapampa, 880 m; 1 November 2003, Krahn 1049. In the Botanical Garden at Bonn there is a culti¬vated specimen of S. inermis in cultivation, having been collected by Miyagawa (Bonn accn no. 6977: "Miyagawa no. 2, Bolivia, Asunta, yungas"). So far I had always doubted these collection data, because S. inermis was only known from northern Colombia and Venezuela, north-western Costa Rica and Mexico (Isthmus of Tehuantepec). Such a remote locality in Bolivia seemed most unlikely to me; maybe labels had been switched or there was some sort of mixing up as happens so often. But the data on Miyagawa's plant were obviously right, confirmed by Krahn's collections (Bauer 2003); and this must inevitably lead to the conclusion that Miyagawa's P. miyagawae had also come from a place near La Asunta and not (as everybody doubted!) from Mataral. For NCL I would like to suggest citing the questionable type locality with a (?) and to give the data for Krahn's collection as well.

Living material examined: BOLIVIA: Cochabamba, Alto Beni, near Mataral, 600 m (?), 19 October 1974, Miyagawa s.n. (type coll.); cult. hort. Bauer and Bot. Gart. Bonn). La Paz, Sud Yungas, 7.7 km S of La Asunta, 750 m, 31 October 2003, Krahn 1044 (cult. hort. Krahn and Bauer).
