1^0 PARSLEY FAMILY 



to 94 in - long- Flowers minute, without petals. Stamen and 

 style 1 each. — In pools at the Soda Springs of the Tuolumne. 

 Widely distributed in the Northern Hemisphere. 



UMBELLIFERAE. Parsley Family. 



Herbs with usually hollow stems and alternate mostly 

 compound leaves, the petioles expanded at base. Flowers 

 small, in umbels or heads. Calyx entire or 5-toothed, the tube 

 wholly adherent to the 2-celled ovary, the 5 petals and 5 sta- 

 mens inserted on the disk that crowns the ovary and sur- 

 rounds the base of the 2 styles. Fruit of 2 seed-like bodies, 

 when ripe separating from each other and usually suspended 

 from the summit of a slender axis; each body marked with 

 ribs and between the ribs are commonly oil-tubes (best seen 

 in slices made across the fruit). 



This is a large and difficult family. Since mature fruits are 

 needed for determining most of the species, and since these 

 are seldom collected by the amateur, only the more showy or 

 otherwise interesting ones are here described.

1. SANICULA. Snake-root. 

 1. S. nevadensis Wats. A glabrous perennial, 3 to 12 in. 

 high, with long taproot. Leaves 1 or 2 in. long, palmately 

 divided, with lobed segments. Flowers yellow, in compact 

 clusters terminating naked peduncles from near the base. 

 Fruit small, bristly all over, with many oil-tubes. — Middle 

 altitudes; not common. S. nemoralis Greene, was described 

 from "Big Trees" and "Yosemite Valley." It is a coarser 

 plant with pinnately divided leaves. Among other species to 

 be expected, especially toward the foothills, is 5". tuberosa 

 Torr., with pinnately divided and finely cut leaves, the stem 

 from a small, globose tuber. 



2. OSMORHIZA. Sweet Cicely. 

 1. O. nuda Torr. Common Sweet Cicely. Stems glabrous
