Native names: Nicaragua: Banak, Sangredrago. Venezuela: Camaticaro, Camaticaro rojo, Camaticaro blanco. Surinam: Baboen- hout. Ecuador: Cacao del monte. Brazil: Ucuhnba vermelha (ex Capucho), Ucncutrana vermelha (ex Froes), Bicniba ocn (ex Claussen). The reduction of several names to V. sebif era, as here proposed, has been undertaken only after the examination of type material and the extensive series cited. The actual type of V. sebifera has not been examined, but there is no doubt that Aublet's plate illustrates the com- mon Guiana form of the species.
The type of V. mnocoa and several other Peruvian and Brazilian specimens have the leaves rounded at base and the secondary nerves comparatively few. Ducke (6: 256) maintains this as distinct from V. sebif era, but I fail to see how it can be maintained in view of numerous connecting forms.
The cotypes of V. panamensis and the type of V. Warburgii have obtuse or rounded leaf bases. The numerous Central American specimens which may be referred to this group have fruits slightly larger than average for V. sebifera, perianths slightly smaller than average, and leaves with a tendency toward eventual glabrescence. But among the cited specimens one may find every variation, and I am unable to draw a definite line between these Central American specimens and typical V. sebifera. Hayes 618, a cotype of V. panarnensis, appears to be a mixture, with foliage of typical Central American V. sebifera and a few detached fruits which probably represent V. Koschnyi. The name V. panamensis is here construed to belong to the foliage of this specimen and the other cotype.
The type of V. venezuelensis bears fruits a trifle larger than average and has the leaf base truncate.
The type of V. boliviensis has the leaves narrow and acute at base and with unusually long petioles. This type of leaf is found in several other Bolivian and Peruvian collections (ineluding the type of V. perutviana tomentosa). But some specimens (e.g., Buchtien 1684) have leaves of the narrow acute type and also leaves which are broad and obviously cordate at base. Since both leaf forms are found on the same plant it is obvious that the character cannot be used to distinguish species or even varieties
V. Mycetis, based on van Hall 8, appears to be a mixture. The type specimen in the herbarium bears branehlets and foliage, while staminate inflorescences are preserved in alcohol. The leaves are essentially identical with those of many specimens of V. sebifera. The inflorescences are either of V. surmnamensis or V. Melinoni (probably the former, but these two species cannot be readily distinguished from inflorescences alone). This reduction is not made without carefully considering the possibility of the type collection being authentically a unit. It must be noted that this type of leaf (large, broad, with spaced secondaries, pilose beneath with stalked stellate hairs) in all known species is associated with staminate flowers which have the anthers distinctly exceeding the filament columnn. Therefore, if V. Mycetis is really a single species, it is unique in this combination. No other specimens can be referred to this species, while the other three species ineintiolied above are known to be common in Surinam. In view of these facts, and lacking evidence that the leaves and infloreseences of van Hall 8 actually came from the same tree, it seems best to reduce the species.
In summing up the species V. sebifera, we find that it has the broadest range of any American myristicaceous plant. In the center of its distribution, Guiana and northern Brazil, it is fairly constant in leaf form, the leaves being cordate at base, large in size, and persistently tomentose. The fruits are of average size for the species taken as a whole. In southern Brazil we see a tendency for the leaves to be even nore broadly cordate at base and with clearly recurved basal nerves. Toward the other peripheries of its range, the species demonstrates leaves varying at the base to rounded and definitely acute. In Bolivia and Peru there is a tendenicy toward longer petioles. In Venezuela and Central America there is a tendency toward large fruits and early leaf glabrescence.
None of these characters seem sufficiently pronounced or constant to make subspecies, varieties, or even forms worthy of nomenclatural distinction. The typical Guiana form is likely to be met with throughout the range of the species
