We got this plant from the collection of the Marie Selby Botanical Gardens, with their accession number of SEL1978-2056. First off, we have doubts of the validity of this name. It is a very large grower with stiff, upright growing branches with elongate segments bearing crenate margins. We think this plant more closely resembles R. oblonga, but are keeping the Selby identity until we can confirm otherwise.
Note: This plant is on C.I.T.E.S. and can not be exported.
