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. Since 1916, the Society has published the peer-reviewed, scientific journal Madroño, 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.
  • 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 students undertaking botanical research within western North America through Paul Silva Student Research Grants.
  • Graduate Student Support. Every other year, in conjunction with our annual banquet, the Society sponsors a student-organized symposium where 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, and 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 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. Additionally, the Society brings botany to K-12 schools through the Botany Ambassador Program, and aims to encourage our next generation of botanists by sponsoring 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.

Dear Members of the California Botanical Society,

The scientific study of plants — as all of science — is based on openness, inclusivity, and mutual respect, and so science cannot thrive in a society that is riven with racism, bigotry, or injustice.

We – the Council of the California Botanical Society – are writing today in solidarity with the Black community to acknowledge and to condemn our country’s long-standing, collective failure to create, support, and maintain a society that is in alignment with its stated commitment to peace and justice for all. We are appalled, repelled, and horrified by the racism and brutality that resulted in the recent murders of George Floyd, Ahmaud Arbery, and Breonna Taylor and we recognize that these are just the latest examples of a long and escalating history of state-supported dehumanization of marginalized citizens and residents of the United States. We support the calls for justice to be brought to the perpetrators of these crimes.

The links between our professional lives, our love for Botany, and our political and social beliefs become impossible to ignore when the lives of our community members are not equally valued by the federal- and state-supported agencies designed to protect them, to ensure their health, and to hear their voices. When our country’s political environment puts the personal safety of any member of CBS, our families, our colleagues and students, our broader social networks, and communities of color at risk while destroying their economic stability, we, as a society, must speak out.

The California Botanical Society is but one of thousands of self-organized communities in which many members are in distress due to a global pandemic, political unrest catalyzed by vicious brutality and divisive leadership, and economic ruin. As a diverse and inclusive organization, we pledge to help find a path forward, not only for our members, but as an example to other formal and informal non-governmental organizations whose members face similar obstacles to their personal and professional well-being.

We affirm that Black Lives Matter, and we have the responsibility to work against racism in all its forms. We welcome input from members who have suggestions for how we can broaden our Society’s inclusiveness and light the way for a more equitable, promising and sustainable future. You can provide anonymous feedback here. We hope to hear from you about the actions we can take to ensure that the next generation of botanists is as stunning and as diverse as our incredible flora.

With our best wishes,

The Council of the California Botanical Society
