Welcome to the UOG Herbarium!

The University of Guam Herbarium specializes in research on the insular floras of Guam, the Northern Mariana Islands, and all of Micronesia -- a region in the Western Pacific of more than 2,000 tropical islands in an area the size of the continental United States. Important collections include those of P.H. Moore, A.F. Rinehart, B.C. Stone, and R.T. Tsuda. The Herbarium contains more than 57,000 specimens (with 46,000 phanerogams and pteridophytes) and is listed in the Index Herbariorum, the world directory of public herbaria.

We accept inquiries for exchange of specimens. Please direct any requests via post to the curator.
