Notes from Britton and Rose 1920

There has long been much uncertainty regarding this species and Dr. Rose, during his trip to South America, in 1915, endeavored to solve the problem. He first visited one of the three localities mentioned in the original description, namely Tijuca, a mountain near Rio de Janeiro. Here he found two species which belonged to the same group, Rhipsalis grandiflora and R. pulvinigera. He then visited the herbarium of the Museo Nacional, where he found specimens of R. neves-armondii. Unfortunately, they did not bear an original label but one doubtless written after the appearance of the description in the Flora Brasiliensis for the three localities mentioned therein. After studying this material carefully, he visited the mountain region just above Tijuca, namely Pica Popagaya, where he feels certain he has collected the true form, although the joints are more terete and the flowers are pure white instead of yellow; it is a singular Rhipsalis and a very shy bloomer. A second visit was then made to Tijuca, but lower down on the mountain, and here he again found this species

forma neves-armondii
