**Notes**: Updated Nov 2016 (Notes update). GH is fully integrated with A and AMES in the Harvard University Herbaria, but specimens from Gray Herbarium should be cited as GH. The 1 943 000 specimens in GH are included in the total given for the Harvard University Herbaria (listed under GH). The previously separate Harvard herbaria (A, AMES, ECON, FH, GH) were fully integrated in the 1980s and are now administered as a single unit. Although loans of vascular plants from the Harvard University Herbaria will include appropriate specimens from A, AMES, ECON, and GH, and also material from the New England Botanical Club Herbarium (NEBC), specimens cited in publications should use the standard abbreviations for each of those herbaria. Correspondence regarding specimens should not be sent to the separate institutions, but to
[email protected]. Work space can be provided for both long- and short-term visitors; written requests, especially for long-term visitors, should be sent to Michaela Schmull (
[email protected]). Also available for study are 50 000 paleobotanical specimens, 33 000 specimens of wood, 38 000 microscope slides of wood, 15 000 slides of other plant parts in the Bailey-Wetmore Wood Collection (Aw), and 11 000 pollen slides.
