The biologist Helen Sharsmith was born today in 1905.
A native Californian, Sharsmith, and her husband both received their doctorates from the University of California, Berkeley.
Sharsmith's dissertation on the Flora of the Mount Hamilton Range of California was published as a book in 1945. Twenty years later, she wrote another book called Spring Wildflowers of the San Francisco Bay Region (1965).
Her husband named a stickseed after her called Hackelia Sharsmithii. It's a pretty little endangered herb in the borage family.
Hackelia sharsmithii is a species of flowering plant in the borage family known by the common name Sharsmith's stickseed.
Adorably, the Sharsmiths had two children - a rich man's family - a boy and a girl.
The boy was named John, after the naturalist John Muir.
The girl was named Linnea, after Carl Linnaeus.
