Discussion:

Type. Ule 8807, Venezuela-Brazil, Roraima, alt 1500-1700 m (nv).

The last-mentioned specimen together with Steyermark 75172 (type, nv) was described recently (Moore, Principes 13: 139. 1969) as a new species, Prestoea steyermarkii. According to Moore, in his original description, “Prestoea steyermarkii is perhaps related to Euterpe (Prestoea) tenuiramosa .... but the latter is described as having a glabrous petiole and a short columnar pistillode: P. steyermarkii has prominent scales on the lower surface of the petiole and a deeply trifid pistillode.” For the present study only the paratype of P. steyermarkii could be studied which did not justify a specific segregation. Consequently P. steyermarkii is considered here to represent a synonym of E. tenuiramosa and is not treated as a distinguishable taxon.
