MiCROCALA QUADRANGULARis Griseb. Whether this South 

 American species is indigenous to California would appear uncertain 

 as to the vicinity of San Francisco. But Dr. Bolander found it 

 " near Mendocino, under Pinus contorta" where it seems milikely 

 to have been brought by the agency of men or cattle. Dr. Engel- 

 mann indicated to me that the stamens are inserted in the very 

 sinuses, not below on the tube as figured by Progel in the Flora Bra- 

 siliensis. Then the stigma, as Dr. Engelmann has also shown in both 

 species of the genus, is separable or in age actually divides into two.
