Vernon I. Cheadle Student Travel Awards
DR. VERNON I. CHEADLE is remembered as a great teacher for the courses he taught at the University of Rhode Island and the University of California at Davis. However, he is most noted for his work as a botanical research scientist. Much of his anatomical collection remains a significant part of botanical history as "The Vernon I. Cheadle and Katherine Esau Structural Botanical Collections", which is now housed at the Vernon and Mary Cheadle Center for Biodiversity and Ecological Restoration at the University of California, Santa Barbara. Dr. Cheadles contributions span 60 years and include over 6,000 preserved (pickled) plant specimens, 64,000 microscope slides supporting the specimens, field collection information including photographs, herbarium voucher sheets, tracheary cell measurements, and general anatomical information is contained in the extensive data card files. The websites for the The Vernon I. Cheadle and Katherine Esau Structural Botanical Collections can be found at: http://ccber.lifesci.ucsb.edu/
In Memorium, VERNON IRVIN CHEADLE 1910-1995, Plant Science Bulletin 1995, Vol. 41, Issue 3
The Botanical Society of America, in conjunction with the Developmental & Structural Section offers four (4), $500 Vernon I. Cheadle Student Travel Awards. Awards are available to undergraduate and graduate students who will be attending and presenting a paper or poster at the annual meeting of the Botanical Society of America. Although it is not a requirement, students who are presenting in a session sponsored by the Developmental and Structural Section will be given the highest priority.
