Abuta manauscnsis Krukoff & Barneby, Mem. N. Y. Bot. Gard. 20(2): 20. 1970.
the protologue of A. manauscnsis we compared the proposed new species with
A. rufescens and A. splendida, mentioning A. candollei only in passing, as having
much smaller staminate flowers. Subsequently we have dissected flowers from two
further collections of A. candollei (Ducke 2162; Froes 26643) and find them, although
still not as large as those of the type of A. manauscnsis (inner sepals 1.7-1.8
not ± 2.7 mm long), virtually identical in form. The androecium, formed of six free
linear filaments which spread apart from their common point of origin and curve
inwards distally toward the prominent bead-Uke anthers, is characteristic of all
material studied. Among species of Abuta with velvety-tomentulose back of the leaf
A. candollei is easily distinguished by the contrast in shape between the Unear outer
and broad, thin-textured inner sepals.
The reduction of A. manauscnsis to A. candollei carries the range of the latter up the Amazon River into Amazonas, whence it has not been reported previously.
