Welcome to the Consortium of California Herbaria Portal (CCH2)
CCH2 serves data from specimens housed in CCH member herbaria. The data included in this database represents all specimen records from partner institutions. The data served through this portal are currently growing due to the work of the California Phenology Thematic Collections Network (CAP-TCN). This collaboration of 22 California universities, research stations, natural history collections, and botanical gardens aims to capture images, label data, and phenological (i.e., flowering time) data from nearly 1 million herbarium specimens by 2022. Data contained in the CCH2 portal will continue to grow even after this time through the activities of the CCH member institutions.

Note also these other portals that will better serve the data needs of more-specialized users:
California vascular plants - CCH1: For California vascular plants linked to the statewide flora project (the Jepson eFlora: http://ucjeps.berkeley.edu/eflora/), please see the original the CCH1 portal (active since 2003).
Pteridophytes - fern portal: A new world-wide Pteridophyte portal is currently in development. Please check back later for a website URL
Macroalgae: For algae specimens, see the Macroalgal Herbarium Consortium Portal
Brytophytes: For bryophyte specimens, see the Consortium of North American Bryophyte Herbaria (CNABH)
Lichens: For lichen specimens, see the Consortium of North American Lichen Herbaria (CNALH)
Fungi: For fungi, see the Mycology Collections data Portal (MyCoPortal)
