Description from Britton & Rose 1923
Acanthorhipsalis crenata (Britton).
=Hariota crenata Britton, Bull. Torr. Club 18: 35. 1891.
Type locality: Yungas, Bolivia.
Distribution: Known only from the type locality.
When first described,,this species was thought to be nearest the Brazilian Rhipsalis platycarpa, which it resembles, but that species has no spines.
Figure 212 is from a photograph of Dr. Rusby's herbarium specimen (No. 2047).
Further detail from Bradleya 18/2000
Lepismium crenatum (Britt.) Barthlott
Range: Small. Endemic to Bolivia, Distribution in Bolivia: Montane rain forests of the Yungas of the La Paz and Cochabamba.
Altitudinal range: 900-2,300 m.
Epiphytism: Obligatory (accidentally saxicolous). Hanging shrub, up to 4 m long.
Flowers: Red. Southern winter.
Fruits: Not seen.
Conservation value and status in Bolivia: not endangered but merits special national attention.
Notes: Quite rare even where it occurs, Apparently favours forests somewhat less humid (but still evergreen) than L. bolivianum and L. asuntapatense, and may be limited to a narrow ecological transition zone between semi-evergreen and perhumid montane forests, suggesting a limited and very fragmented distribution. Recently found in Cochabamba (E. Aguilar in the Yungas of Cochabamba nearby Tablas Monte; Kimnach 1995), and in the Yungas of La Paz (nearby Coroico; Kirschnek pers. com.). The closely related L. micranthum (Vaupel) Barthlott, known only from the Sandia valley, Peru, about 50 km from Bolivia, might occur in Andean valleys in the westernmost Department of La Paz.
