unknown plant

[Gea Zijlstra]

An unknown plant from Pibiri, near Mabura, Guyana, has puzzled the Utrecht
plant taxonomists during the last seven years. Three photographs and a short
description by Paul Maas have been placed on the website of the Utrecht
Herbarium (NHN-Utrecht): http://www.bio.uu.nl/~herba/news.html
Who knows the name? Reward for the first good suggestion: one copy of Maas &
Westra 'Neotropical Plant Families' ed. 2, 1998.
