GERANIUM FAMILY 5 



ish, 3-5 mm. long; carpel-bodies sparingly pubescent, and glandular-hispid on the keel- seeds 



.5-0.5 mm. long, coarsely reticulate. 



Moist soils, Transition and Canadian Zones; eastern British Columbia to Saskatchewan and South Dakota 

 south to northern Mexico. In the Pacific States it ranges from the Cascade Mountains of southern Oregon south 

 through the Sierra Nevada to the mountains of southern California. Type locality: vallevs of thp RorW Mnnr. 

 tains, collected by Drummond between latitudes 52° N. and 54° N. May-July. ^ 



Geranium concinnum G. N. & F. F. Jones, Rhodora 45: 38. 1943. Somewhat intermediate between G 

 Rtchardsonit and G. cahfornicum. The length of the free style-tips is intermediate between the two species- hairs 

 of the pedicels are tipped with yellowish glands instead of purple; pubescence of the stem and petioles differs 

 from both species in being finely retrorse-pubescent to nearly glabrous; petals 10-15 mm. long pale pink or 

 lavender. Known localities are: Olancha Mountain and Kern River (type locality), Tulare County Frazier 

 Mountain, Ventura County; and Bear Valley, San Bernardino County, California; all stations at altitudes of 

 7,000—9,000 feet. 



13. Geranium californicum G. N. & F. F. Jones. California Geranium. Fig. 2975. 



Geranium leucanthtim Small, N. Amer. Fl. 25: 18. 1907. Not Griseb. 1874. 

 Geranium californicum G. N. & F. F. Jones, Rhodora 45: 38. 1943. 



Perennial, with a heavy caudex and ascending rather slender stems, 2-4 dm. high. Leaves 

 thin, 3-parted, the divisions incised or toothed, more or less appressed-pilose ; petioles with 

 spreading or retrorse pilose hairs; pedicels and sepals densely glandular-pubescent, the glands 

 usually yellowish; petals 16-21 mm. long, veiny, white or pale pink; style-column 20-25 mm. 

 long; style-branches 6-7 mm. long; carpel-bodies hairy. 



Moist woods or meadows, Arid Transition Zone; Sierra Nevada, from Yosemite National Park southward 

 and in the San Bernardino and San Jacinto Mountains, California. Type locality: Pine Ridge, Fresno County' 

 California. June-Aug. 



Pelargonium L'Her. ex Ait. Hort. Kew. 2: 424. 1789. The well-known pelargoniums or "geraniums" of 

 gardens belong to this African genus, which is distinguished from true geraniums chiefly by the irregular 

 flowers. Several species often grow spontaneously along roadsides or in waste places where garden refuse has 

 been dumped, especially in southern California. 



2. ERODIUM L.Her. ex Ait. Hort. Kew. 2:414. 1789. 



Herbs with mostly jointed nodes, opposite or alternate stipulate leaves, and axillary 

 umbellate nearly regular flowers. Sepals 5, imbricated. Petals 5, hypogynous, imbricated, 

 the 2 upper slightly smaller. Glands 5. Anther-bearing stamens 5, with slightly dilated 

 filaments alternating with as many sterile filaments. Styles becoming spirally coiled after 

 splitting away from the central column, pubescent on the inner face. Carpel-bodies nar- 

 rowed at the base, closed. Seeds smooth. [Name Greek, meaning heron, in reference to 

 the beaked fruit.] 



About 60 species, widely distributed in temperate and subtropical regions. Type species, Erodium crassi- 

 folium Soland. 



Leaves not pinnately parted. 



Leaves palmately parted, lobed or toothed, cordate at base, about as broad as long. 



Pedicels closely appressed-pubescent; leaves deeply cleft or divided. 1. E. texanum. 



Pedicels glandular-pubescent with spreading hairs; leaves shallowly lobed or toothed. 



2. E. macrophyllum. 

 Leaves pinnatifid, much longer than broad, not cordate at base. 3. E. Botrys. 



Leaves pinnately parted. 



Sepal-tips without bristle-like appendages; anther-bearing filaments 2-toothed. 4. E. moschatum. 



Sepal-tips with 1 or 2 bristle-like appendages; anther-bearing filaments toothless. 5. E. cicutarium. 



1. Erodium texanum A. Gray. Texas Filaree. Fig. 2976. 



Erodium texanum A. Gray, Gen. III. 2: 130. 1849. 



Stems several from the base, 4-25 cm. long, the whole plant appressed-pubescent and canes- 

 cent, not glandular. Leaves deltoid-ovate or ovate, 1 . 5-5 cm. long, cordate, subpalmately 3-5- 

 lobed, crenate-dentate ; sepals minutely awn-tipped, 10-13 mm. long; petals purple, the early 

 ones exceeding the sepals, the latter much reduced; fruiting style-beak 4-6 cm. long. 



Sandy soils. Upper and Lower Sonoran Zones; Mojave and Colorado Deserts, southern California to Lower 

 California and Texas. Type locality: Texas. April-May. 



2. Erodium macrophyllum Hook. & Arn. Large-leaved Filaree. Fig. 2977. 



Erodium macrophyllum Hook. & Arn. Bot. Beechey 327. 1837. 



Mostly nearly or quite acaulescent, puberulent with few interspersed glandular hairs at least 

 on the pedicels. Leaves triangular-ovate or reniform, crenate-serrate, sometimes crenately-lobed ; 

 peduncles exceeding the leaves, sepals glandular-hirsute, minutely awn-tipped, the outer 11-16 

 mm. long; petals equaling the sepals, dull white; carpel-bodies truncate, 2.5-4 mm. broad at apex, 

 densely velvety-pubescent. 



Occasional in dry grassy places in the valleys or low foothills, Upper Sonoran Zone; Oregon to Lower 

 California. Type locality: California. March-May. 



Erodium macrophyllum var. californicum (Greene) Jepson, Fl. W. Mid. Calif. 247. 1901. (Erodium 

 californicum Greene, Fl. Fran. 99. 1891.) Like the typical species in general habit; peduncles and pedicels less 

 puberulent, but abundantly beset with long gland-tipped hairs; petals purple. Central and southern Calitornia. 

 Type locality; "Berkeley Hills and eastward in the Mt. Diablo Range."
