Annetta Carter Memorial Fund Grants
Next deadline: December 31, 2025

Leave a Legacy, Plant a Seed
As western North American wild flora has become increasingly imperiled, grants available to young botanists for innovative botanical research can make a career-changing difference. A donation of as little as $600 can seed a fund in your name.

The newsletter and digital forum of the California Botanical Society.

Botany Ambassador Program
We invite undergraduates, graduate students and postdocs to introduce botany to K-12 and beyond, “interpret” Madroño articles, and review Madroño manuscripts.

About the Society

The California Botanical Society was founded by Willis Linn Jepson in 1913 and serves a major role in advancing Western American botany with its five primary program services:

  • Scientific Publications. The Society has published the peer-reviewed, scientific journal Madroño since 1916. Madroño is the leading source of research articles on the ecology, systematics, floristics, restoration, and conservation biology of Western American flora, including those of Mexico, Central and South America. Madroño is available to our individual members online through BioOne (Volumes 52, 2005 to current). All issues of Madroño are available through JSTOR, a digital library for scholarly journals, and through the Biodiversity Heritage Library.
  • Annual Banquet. The Society sponsors a banquet and lecture held annually in California.
  • Research Support. The Society supports botanical research on the green plants of Baja California through grants under the Annetta Carter Memorial Fund, and supports graduate and undergraduate students undertaking botanical research within western North America through Paul Silva Student Research Grants.
  • Graduate and Undergraduate Student Support. Every other year, in conjunction with our annual banquet, the Society sponsors a student-organized symposium where graduate and undergraduate students come together to present their research and participate in a diverse community of botanists. The Society provides reduced prices and other subsidies to students to encourage their participation in all Society events, including travel grants to attend the biennial Graduate Student Symposia. Student research support is provided through Paul Silva Student Research Grants and Annetta Carter research grants. Students are encouraged to publish their research in Madroño. As part of the Botany Ambassador Program, the Society offers professional development opportunities to students, including writing non-technical summaries that “interpret” recent Madroño articles, serving as reviewers of Madroño manuscripts, and bringing botany to K-12 schools.
  • Community Outreach. The CalBotSoc Botany Speaker Series showcases and promotes the work of early career botanists. The Society sponsors social events for professional networking purposes, field trips, and lectures. The Society also publishes Nemophila, a digital newsletter and forum covering topics of interest to our members, including upcoming meetings, new botanists in the state, and articles about plants and the environment. To encourage our next generation of botanists, the CalBotSoc Botany Ambassador Program brings botany to K-12 schools, and sponsors awards for outstanding botany projects presented by budding K-12 scientists at recognized California science fairs.

The Society welcomes membership by all individuals interested in Western American botany. Subscriptions to Madroño are available for institutions. Membership dues and institutional subscriptions support the publication of Madroño, and our grants and education programs.

Remembering our friend, colleague and fellow botanist, Gabriel Trujillo

It is with deep devastation that we mourn the loss of Gabriel R. Trujillo who was murdered on June 19th in Sonora, Mexico while driving through Mexico collecting plants for his Ph.D. research.

Gabriel was brilliant, genuine, talented, adventurous, brave, generous, and above all unfailingly kind and loving to everyone. He was a deeply spiritual Danzante and was reconnecting to his Indigenous Opata and Nahua ancestry.

We are sharing a GoFundMe link to support his family.
