I have seen no authentic specimens of this species, and so can only rely for this 
identification upon Kunth’s description (Nov. Gen. et Sp. iii. p. 146). The four species 
M. Coito, Miers, M. platypoda, Miers, M. corymbosa, Griseb., and M. laurifolia, Miers, 
are evidently very closely allied. The first of these has, however, a calyx straight 
to the tip; the pedicels of M. platypoda are winged, while acuminate leaves subcordate 
at the base are characteristic of M. corymbosa. Our plant, with the recurved calyx-tip 
of M. corymbosa and M. laurifolia, has leaves which exactly agree with the description 
given of those of the latter species. [Venezuela. |
