Pistil 1, simple; style laterally inserted and flexuous toward the base; 

 ovary 1-eelled, 1- or 2-ovuled, becoming an achene covered by the 

 hardened persistent calyx-tube. 



1. A. fascicnlatum, Hook. & Am. Shrub 2—20 ft. high, the virgate 

 branches covered with leaf -fascicles : leaves linear-subulate, 2 — 5 lines 

 long, pungently acute, glabrous, often resinous; stipules small, acute: 

 fl. crowded, sessile; calyx 1 line long, bracted at base, the teeth much 

 shorter than the small petals : ovary obliquely truncate. — A most char- 

 acteristic bush of the summits and elevated slopes of the Coast Range. 



5. AC.EUA, Mulis. Perennial herbs, or the stems somewhat woody 

 at the decumbent or creeping base. Leaves unequally pinnate; leaflets 

 incised or pinnatifid. Flowers in terminal more or less spicate clusters. 

 Oalyx-tube oblong, contracted at the throat, persistent, at length armed 

 with retrorsely barbed prickles; limb 3 — 7 parted, valvate, deciduous. 

 Petals 0. Stamens 1 — 10. Pistils 1 or 2; ovary free from the calyx; 

 style terminal; stigma capitate, multifid; ovule 1, suspended. Achene 

 enclosed in the hardened calyx-tube. 



1. A. triflda, Ruiz & Pavon. Stems 1 ft. high, leafy mostly at the 

 creeping and woody base; herbage silky- villous: leaflets 9 — 13, oblong- 

 ovate, 3—5 lines long, pinnately cleft into 3 — 7 segments: fl. small, 

 greenish purple in an interrupted spike; filaments exserted: fr. ovate, 

 2 lines long, 3 — 4-angled; angles with 2 — 4 stout prickles, the intervals 

 with shorter ones. — Grassy summits or northward slopes of hills along 

 the sea coast. April — June. 



6. AGRIMONIA, BrunfeU (Agbimont). Perennials with odd-pinnate 

 leaves and long slender terminal racemes of small yellow flowers. Calyx- 

 tube urceolate; throat encircled by a border of hooked prickles; limb 

 5-lobed, at length connivent. Petals 5. Stamens 5— 15, in 1 row. Pistils 

 2, distinct, free from the calyx; styles terminal; stigma dilated, 2-lobed: 

 ovule pendulous. Achenes 1 or 2, enclosed in the bur-like calyx. 



1. A. Eupatoria, L. Hirsute or glabrate, 2 — 4 ft. high, sparingly 

 branched above: leaflets 5 — 7, usually 2 — 3 in. long with very small ones 

 intervening, oblong-obovate, coarsely toothed, acute at each end; stipules 

 large, semicordate, toothed or lobed: calyx in fruit }£ — % in. long, the 

 tube 10-sulcate above: achene 1, subglobose, 1 line thick. — Apparently 

 widely disseminated in California, but seldom seen. 



7. AIjCHEMILLA, Tragus. Herbs of various habit; ours small 

 annuals with leafy stems, and minute green flowers fascicled in the axils 

 of the palmately lobed leaves. Calyx- tube urceolate; limb 4— 5-cleft, 

 with or without as many minute bractlets or intervening teeth. Stamens 

 1 or 2, minute. Pistils 1 or 2; style basal or lateral; ovule 1, ascending.
