Brodiaea santarosae: A New Species

This species was previously confused with B. filifolia and B. orcuttii.

The following images show brodiaea flowers that superficially resemble an oversized B. orcuttii, except they have longer filaments & styles. They also have slender, erect or spreading staminodes.

Armstrong K. Madore 927 (holotype UCR; isotypes RSA, SD).
