9'8" GERANIACE^. 



filaments white-villous : beak of fruit glandular, \y^ in. long, short- 

 pointed.— In dry open places of the Sierra, from Fresno Co. northward.. 



6. G. Ricliardsouii, F. & M. Ind. Sem. Petr. iv. 37 (1837) : G. alhi- 

 florum, Hook. Fl. i. 116. t. 40 (1830), not Ledeb. (1829). More slender,, 

 somewhat retrorsely pubescent, the stalklets more or less villous and 

 glandular : uppermost leaves lanceolate, serrate but not lobed : sepals- 

 canescent and glandiilar : petals clear white, villous on the inside. — Range 

 of the preceding, but at higher altitudes and only in moist soils. Flowers, 

 invariably white. 



2. ERODIUM, L'lleritier (Stobksbilt.). Vegetative characters of 

 Geraniuni, but leaves often pinnate. Flowers and fruit almost the same ; 

 but fertile stamens 5 only, as many scale-like sterile filaments alternating 

 with them. Beak of carpel when ripe silvery-bearded within and spirally 

 twisted. 



* Naturalized species ; leaves pinnate. 



1. E. cicuTAKiUM, L'Her. in Ait. Kew, ii. 414 (1789) ; Linn. Sp. PI. ii. 

 680 (1753), under Geranium. Leaves chiefly radical, in a depressed 

 rosulate tuft, usually 6—10 in. long, the many leaflets laciniately 

 pinnatifld with narrow acute lobes ; cauline leaves reduced ; peduncle& 

 exceeding them and bearing an umbel of 4 — 8 small bright purple 

 flowers : beak of carpels 1 — 2 in. long.— Frequent in the Bay region ; 

 perhaps more common in the interior and southward. This is one of the 

 pasture plants commonly called Pin-clorer and Alfilerilla ; but it is not 

 the important one. The herbage is rather strongly aromatic for a good 

 fodder plant. 



2. E. MOSCHATUM, L'Her. 1. c; Rivinus, Pentap. t. 110 (1699), under 

 Geranium. Coarser and larger, the radical leaves ascending, 1 ft. long 

 or more ; cauline more ample ; leaflets unequally and doubly serrate : 

 corolla pale and rather dull purple or rose-color : herbage with a delicate 

 marshy odor. — This is the prevalent Pin-clover of middle California, 

 where it is a hundred fold more abundant than any other species, of 

 ranker growth, its foliage not depressed, and a moist valued plant for 

 pasturage. E. cicularitim is less common and of little relative value. 

 Both species are annual, and begin their growth with the coming of the 

 first autumnal rains, and are in flower through all the later winter and early 

 spring months. Though well established in California from a very early 

 period, neither of them is with reason believed to be indigenous. The 

 New World type of Er odium is simple-leaved. 



3. E. BoTRYs, Bertoloni, Amoen. Ital. 35 (1819). Radical leaves rosu- 

 late, closely depressed, shining above, of oblong obtuse outline, the 

 segments coarsely dentate : stems short : sepals 4 lines long ; pale
