Abstract
Despite their economic and ecological importance, Amazonian palms have been largely neglected by contemporary taxonomists. The resulting confusion at the specific level is a serious impediment to research efforts by specialists in other fields. To assess the state of systematic collections presently available in Amazônia, we conducted a survey of the palm specimens in three Brazilian herbaria (MG, IAN and INPA). Twelve criteria were utilized to measure the quality of the specimens. We found that most of the 897 specimens are reasonably complete in a physical sense, but a large proportion lack crucial information on their labels. Curating facilities are in serious need of improvement, as is evident from the significant (26%) percentage of specimens found to be in an unreasonable state of preservation. A checklist of the 232 currently recognized palm species in Brazilian Amazônia shows that 145 (62.5%) are not represented by identified specimens, and that the representation which does exist lacks depth. To improve the quality and representativeness of collections in regional herbaria, we suggest procedures for collecting and storing palms as well as policies designed to intensify collecting efforts in Amazônia.
