246 GERANIACE^. 



California; " it is a nearly related species with the leafy "branches 

 from a stout erect woody caudex. 



2. O. Oregana Nutt. Ebdwood Sokrel. Acaulesoent, more or 

 less rusty-viJous; leaflets broadly obcordate, broader than long, 1 to 

 IJ in. long; scapes from creeping rootstocks equaling or exceeding 

 the leaves, 2-bracted near the top, commonly 1-flowered; petals- 

 oblong-obovate, 9 to 12 lines long, pink, white, or rose-color, often 

 veined with purple; capsule linear, 9 lines long; cells about 6-seeded. 



Shady woods in the Kedwood Eegion from Santa Cruz northward. 

 Mar. -Apr. 



2. GERANIUM L. Cranksbill. 



Herbs (ours annual) with forking stems, swnl'en nodes and stipu- 

 late palmately parted leaves. Peduncles axillary, umbellately 2 to 

 3-flowered, or 1-flowered. Plowers regular, 5-merous, the sepals 

 imbricate in the bud. Stamens 10, sometimes slightly connate at 

 base, all with perfect anthers, the 5 longer alternate with the petals 

 and with glands at their base. Carpels 5, 2-ovuled, 1-seeded; styles 

 united around a central elongated axis (prolongation of the receptiicle), 

 separating elastical'.y from it when mature, and forming a coil which 

 is the "tail " of the carpel and is nearly glabrous inside. Cotyledons 

 plicate, incumbent on the radicle. (Greek geranos, a crane, from the 

 elongated fruit-bearing beak.) 



Flowers light pink . ... ..... . 1. G. Carolinianum. 



Flowers purple ... . . 2. (?. dissectum. 



1. G. Carolinianum L. Carolina Geranium. Hirsute- 

 pubescent and ofien somewhat glandular; smaller plants erect, the 

 larger ascending or decumbent, 7 to 14 in. high; leaves palmately 

 5 to 7-parted, the cuneate segments more or less incisely dissected or 

 toothed, the ultimate segments rather broad; peduncles commonly 

 shorter than the petioles; flowers about 3 lines long; petals light 

 pink; beak of fruit looselv villous or glandular; carpels hairy, usually 

 black; seed reticu'ately ridged or pitted. 



Naturalized plant, at one time more common in the Bay Region 

 than now. Mar. -Apr. 



2. G. dissectum L. Common Geranium. DifFering little 

 from the last, but the primary lobes of the leaves very narrow, with 

 the ultimate divisions mostly slender, somewhat falcate, and acute; 

 petals rose-purple. 



An Old World species naturalized in California not many years 

 since and recently became more common than the preceding. 



G. piLOSUM Porst, of Au.'stralia and New Zealand, adventive at 

 Alameda and San Francisco, is a similar species but is perennial by a 

 thick rootstock and retrorselv canescent-pubescent but not glandular. 

 G. parviflorum Willd., collected at Mt. Tamalpais and Duncan's 

 Mills, has few points of diflTerence with the precedi' g or with G. dis- 

 sectum. G. moUe L; has glabrous carpels, conspicuously wrinkled 

 transversely, and unpitted seeds; reported as occurring at San Fran- 

 cisco and at Olema.
