synonym Acanthorhipsalis monacantha, .

A young plant. It suffered a little during the winter. During freezing I kept her protected in the gardening tool shed. But it made ​​two flowers.
All pictures were taken yesterday, April 20, 2014, except one (mentioned below).

The flower is open just one day

Yesterday the first flower was gone and closed:

Second flower.
Unopened flower bud (of second flower)




Really nice plant - I'm not at all familiar with it. It looks like a Stapelia but the name sounds like Rhipsalis.

In the end, only kindness matters.

Science is not the answer, it is the question.

I looked up Lepismium and apparently Lepismium and Rhipsalis fall under the same "Tribe" (I didn't know there was such a thing as "Tribe"): Rhipsalideae. They are in different Genera though. So, they're related essentially. Interesting to know!




Yes, the same plant. Acanthorhipsalis monacantha is synonim for Lepismium monacanthum.

When a plant is reclassified into another genus the rule requires keeping the same second word in the binomial names.
But at the same time the rule requires the according of the epithet (the second word in the binomial name), with generic name (first word of the binomial name).
monacantha is the feminine form of the word and monacanthum is the masculine form. (rule of Latin language).
Monacantha originated in Greek. "Monos" - one , and "akantha" - spine.
So, monacantha, monachantos = one spin. Description suggested by the epithet "one spine" is more or less accurate.

(I am not sure if the word 'generic', used above, it is correct in English. I used it here, with the meaning of the word who show the genus where the plant is classified.)

This cactus like other cacti and many other plants have many synonims.
Other synonims for Lepismium monacanthum: Rhipsalis monacantha, Pfeiffera monacantha, Acanthorhipsalis incahuasina, Pfeiffera incahuasina, Pfeiffera monacantha
In fact the correct, full name of this plant it is
Lepismium monacanthum ( Griseb. ) Barthlott - Bradleya 5: 99. 1987
