Description:Distribution and Ecology - Distribution. Large tree 20-25 m, the branchlets more or less sulcate becoming terete and somewhat striate with age, deep brown tomentose, the inflorescences maroon or yellow-brown tomentose up to 19 cm long, according to the collector, axillary, the subtending leaves oblong-elliptic with shining more or less glabrous uppersurface, yellowish tomentose beneath on the venation (silvery beneath, according to the collector), rounded at the base and very long-acuminate at the apex. Aside from the type locality, this has not been reported elsewhere until the present. VENEZUELA.

Discussion:Despite the disjunct distribution, the fruiting specimen from Guayana appears in every way to be conspecifle with Lasser's species. I have not seen the type, but the isoparatype, Williams 10718, a flowering specimen, is at hand. The fruiting material is perhaps not fully mature, but may be described as follows: Infructescence to 16 cm long, sturdy, pedicel stout to 2.5 cm long, the rachis brown-magenta, according to the collector, and clothed with a dense tomentum, brownish in the dried state, the maroon, subsessile, hemispheric cupule is campanulate, 8-12 mm long, 4-7 mm deep and up to 15 mm in diameter, subtending the pale green, obovoid (1.5-2.5 X 0.7-1.5 cm) fruit and enclosing it for approximately one-third of its length. The leaf surface of the specimen cited is not shining above as that of the type, nor is the reticulation as pronounced. The species most closely resembling N. meyeriana is Nectandra kunthiana (Nees) Kostermans [Acrodiclidium kunthianum Nees; Ocotea kunthianum (Nees) Mez] which differs in the more consistently oblong leaves, sharply reticulate throughout, with presumably a narrow, slightly acute cusp at the apex. Both species have a shining upper leaf surface which is more or less densely, minutely punctulate and roughly, minutely granular. It would be necessary to compare the types of both taxa, in order to be certain of the genus. The Martin number cited by Mez shows a consistently longer fruiting pedicel than that of the Steyermark & Dunsterville number. Schomburgk 798, cited by Mez, also a staminate specimen, is very definitely an Ocotea. The isoparatype of N. meyeriana, LI. Williams 10718, has seemingly pistillate flowers with expanded petalloid stamens of the two outer cycles more or less simulating the stamens of the genus Nectandra. The illustration accompanying the type, which latter description I have not seen, shows what appears to be a pistillate flower also; the cells of the stamens are not well defined. Until such time as the types are available, it seems preferable to maintain both species.
