_ Specimens collected on the sbores of Monterey Bay, Monterey, California (Pl. Calif. Distr. 
Univ. Calif. no. 88) are believed by Mrs. K. Brandegee to represent a hybrid between Abronia 
latifolia and A. umbellata. In habit the plants are said to resemble A. Jatifolia; the perianth is 
either pink or yellow. Aside from the color of the flowers, the specimens seem to agree very well 
with typical A. umbellata.
