ARALIACEAE. Aralia Family 



Ours perennial herbs. Closely allied to Umbelliferae, but the stems solid, the 

 petals not inflexed and the ovary 2 to 5-eelled. Petals, stamens and styles 5. 

 Calyx-tube coherent with the ovary, its limb a mere rim with 5 salient teeth. Fruit 

 berry-like, containing as many 1-seeded nutlets as there are carpels. — Genera 51, 

 species 400, all continents, but mostly tropical. 



1. ARALIA L. 



Leaves alternate, very large, compound. Flowers small, whitish, borne in 

 panicled umbels, the pedicels pointed. Styles united to the middle. Embryo mi- 

 nute. — Species 30, all continents save Africa. (Derivation uncertain.) 



1. A. calif ornica Wats. Elk Clover. Stems simple, stout, 6 to 10 feet high, 

 arising from a large rootstock with milky juice; herbage glabrous, subulate-sca- 

 brous on the main stem; leaves 1 to 5 feet long, the blades ternate, then pinnately 

 3 to 5-foliolate, 1 to 5 feet long; leaflets ovate, sometimes elliptic, serrate, acuminate, 

 subcordate at base, % to 1 foot long; panicles 1 to 1^2 feet long; flowers 11/2 lines 

 long, on pedicels I/2 inch long; ovary red, becoming a globular black berrj^ 2^ 

 lines in diameter. 



Shaded caiions in moist spots and beds of living mountain streams, 100 to 2500 

 feet: Coast Ranges from Del Norte and Siskiyou Cos. to San Luis Obispo Co.; 

 Sierra Nevada from Plumas Co. to Calaveras Co.; coastal Southern California. 

 July. 



Geog. note. — Aralia californica has not been reported from the Sierra Nevada south of Cala- 

 veras Co., nor is it kno-nTi nor to be expected in the inner Coast Eange from the Yollo Bolly Mts. 

 southward to the Diablo Eange between Fresno Co. and San Luis Obispo Co. In the northern 

 Sierra Nevada, where it is only slightly known, many stations for it, between Shasta Co. and 

 Amador Co., will probably be discovered. In Trinity Co. it is called Spig-nut.

UMBELLIFERAE. Parsley Family 



Herbs with commonly hollow stems and often dilated petioles. Leaves com- 

 monly alternate or basal, compound (sometimes simple), usually much incised or 

 divided. Flowers small, in compound umbels, or the umbels sometimes simple or 

 capitate. Umbels when compound with the peduncle divided at summit into a 

 number of rays, each ray bearing a secondary umbel termed an umbellet. Umbel- 

 lets commonly subtended by bractlets (forming an involucel); rays commonly 

 subtended by bracts (forming an involucre). Calyx-tube wholly adnate to the 

 ovary; calyx-teeth small, sometimes obsolete. Petals 5, usually with an inflexed 

 tip. Stamens 5, inserted on an epigynous disk. Ovary inferior, 2-celled, one hang- 

 ing ovule in each cell. Styles 2, united below and forming a swollen or cushion-like
