Paul Silva Student Research Fund
Annetta Carter Memorial Fund
Leave a Legacy, Plant a Seed
In recent years, as western North American wild flora has become increasingly imperiled, a few hundred dollars at a critical time for innovative botanical research can make a career-changing difference to young botanists. With this great need in mind, we invite those of you who are seeking novel ways to make a difference to offer your support to the Society in the following ways:
(1) Augment our current research endowments: Please consider donating whatever you can to the Paul Silva and Annetta Carter endowments above; we’d love to increase the size, number, and frequency of these awards.
(2) Create a new named permanent endowment: Offer a donation of sufficient size to create a named endowment (in your name or in the name of an honored mentor or loved one) from which the interest can be drawn in perpetuity to provide annual or biennial grants (e.g., $600 - $1500) to early-career botanists.
(3) Create a new named short-term fund: Offer a donation of sufficient size to create a named fund from which the capital can be drawn over the next three to five years to provide larger (e.g., $1500 - $3000) annual grants to early-career botanists. You may either specify the amount of each annual grant or leave this decision to the Society's Council.
(4) Fund banquet tickets for students: Support the attendance of a student at our annual banquet that follows our biennial Graduate Student Symposia. These $25 tickets are often out of reach of students, so a small donation could go a long way toward helping our students network informally with a wide range of professional botanists. Your donation will be acknowledged at the banquet and on our website.
Should you wish to discuss in detail these tax-deductible (or other) options, please email Susan Mazer or any other Council member. If you feel ready to contribute, send a check to the Society's address below, with instructions for how you wish it to be used, or you may donate to our specific funds and programs above.
