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.
