The species of Chusquea (Poaceae: Bambusoideae) with verticillate buds

Abstract

A natural alliance of four species of Chusquea is characterized by having verticillate branches and a spikelet in which the transitional glumes one and two are very small or scalelike, and transitional glumes three and four are about equal to each other and about one-half or three-quarters as long as the lemma. Two of the four species, C. circinata and C. coronalis, are described as new and are provided with illustrations. The other two species, C. liebmannii Fourn. and C. pittieri Hack., are included in a key. The types and other collections are cited for the four species and their relationships are discussed. © 1978, The New York Botanical Garden. All rights reserved.
