Rhipsalis bauchienii

R. buchtienii, and R. buchenii seem to be the same plant with different spelling. As at Apl 2011 have not been able to check any publications to prove either way.
Detail in B&R IV 247. 1923
Rhipsalis bucheni Behagnon (Rev. Hort. 85: 436. f. 152. 1913) we know only from the illustration of a poor potted plant and an incomplete description.
Treated as L. lumbricoides fa lumbricoides by B&T 1995
