Welcome!

The Humboldt State University Vascular Plant Herbarium (HSC) consists of nearly 100,000 specimens, with a strong emphasis in the flora of northwest California and southwest Oregon. Established in 1960, the Herbarium serves as a botanical resource for students and faculty, as well as, community members and professional botanists.

The Vascular Plant Herbarium is one part of the larger Humboldt State Herbarium which includes reference specimens and teaching collections for our courses in agrostology, bryology, mycology, phycology, and plant taxonomy.

Our collections offer excellent opportunities to learn more about the rich diversity of our native flora, local unique and rare plant species, and exotic and invasive weeds. The Herbarium also participates in loan and exchange programs with other herbaria throughout the country.
