Monographs Details: Anomospermum matogrossense Krukoff & Barneby
Authority: Barneby, Rupert C. & Krukoff, Boris A. 1971. Supplementary notes on American Menispermaceae. VIII. A generic survey of the American Tricilisisae and Anomospermeae. Mem. New York Bot. Gard. 22: 1-89.
Family:Menispermaceae
Discussion:This species is known only from staminate flowering material and cannot be firmly assigned to the genus until fruit is found. It could represent a species of Orthomene. The foliage is suggestive of O. schomburgkii, but the apex of the petiole is subterete and the sepals are all copiously strigulose externally. The plant differs from Amazonian A. reticulatum in the finely reticulate leaf-blades. In the protologue we compared A. matogrossense with A. steyermarkii, from which it differs in its relatively small leaves and in details of the staminate petals. No other Anomospermum and no Orthomene is known to occur in the State of Mato Grosso and only A. reticulatum or O. schomburgkii could reasonably be expected there.
