  • Discussion

    N. T. Silva 843 is a voucher for a sample of wood for chemical studies. In the context of sect. Elissarrhena this species is unique because of its coarsely reticulate leaves which turn brownish-olivaceous when dried. The dichotomously cymose staminate inflorescence is not exactly matched in the section, and is very unlike that of sect. Anomospermum. The erect filaments bearing prominulous, collateral anther-sacs at apex are of the same type as in A. solimoesanum, significantly differing from the cobra-shaped, distaUy incurved stamens of A. grandifolium.

    It should be noted that features of stature and pubescence contributed to the protologue by the sterile specimen other than the type are foreign to A. bolivianum as we understand it today. The contaminant is now thought to represent A. chloranthum subsp. chloranthum (Krukoff 10639).
