Washington Flora Checklist A Checklist of the Vascular Plants of Washington State Hosted by the University of Washington Herbarium |
AboutThe Washington Flora Checklist aims to be a complete checklist of the vascular plants of Washington State. The checklist currently contains 3681 unique taxa.
Taxa included in the checklist:Fred Weimnann initiated development of the checklist in 1998, and with the help of Peter Zika and others a draft checklist was completed by 2002. In 2007 the checklist was transferred to the UW Herbarium, funded by grants from the Bureau of Land Management and Washington Native Plant Society.
Please note: This checklist is still a work in progress. Use it at your discretion. Families and taxa updated from 2004 and on are the most reliable.
