42 LOASACE^. 



GODETIA. 



G. micropetala, Greene. Erect, 1-3 feet high: spike rather short: calyx tube 2 

 lines long, segments 4 lines, the slender tips twisted in the bud: petals linear-lanceolate, 

 3 lines long: stigma purple: capsule sessile. Contra Costa Co. 



G. rubicunda, of the Bay -Reg. Bot., may be a variety of Q. Amo&na. 



CLARKIA and EUCHABIDIUM. 



In Bay-Reg. Bot., Eucharidium is put under Clarkia. C. grandiflora is proba- 

 bly a more branching and larger flowered form of Eucliaridiuxn concinnum. E. 

 Breweri is the rarest and most beautiful of the genus. It was discovered on Mt. Oso 

 in Stanislaus Co., and has been collected at the Geysers and on Mt. Hamilton. The 

 flowers have air almost perfectly square outline, the long middle lobes of the petals 

 forming the angles. 



BOISDUVAUA. 



B. glabella, Walp. A span or two high: leaves ovate- lanceolate, serrulate, bluish, 

 densely soft-hairy to glabrous, 5 lines long: flowers in a terminal, leafy spike, or some 

 in the lower axils, about a line long. 



LOASACE^E. 



Herbaceous plants with either stinging or jointed and rough-barbed hairs; no stipules, 

 calyx tube adnate to the 1-celled ovary. Stamens usually very numerous. Key to 

 genera and species, p. 128. 



MENTZELIA. 



Calyx cylindrical to ovoid; the persistent limb 5-toothed. Petals 5 or 10: stamens 

 numerous, inserted below the petals on the throat of the calyx: filaments free or in 

 clusters opposite the petals, filiform or the outer petaloid. Style 3-cleft, the lobes 

 often twisted. The leaves are alternate, mostly coarsely toothed or piunatifid; flowers 

 white to yellow or orange. 



M. affinis, Greene. Similar to M. dispersa, but stouter, often 2 feet high, simple 

 and leafy below, widely branching above: leaves lanceolate, deeply sinuate-pinnatifid: 

 flowers 6 lines broad: capsule an inch long, slender. 



M. pectinata, Kell. Stem usually simple, 4-8 inches high, clothed like the leaves 

 with barbed hairs: flowers deep yellow, an inch broad: petals mostly obcordate, with a 

 minute cusp in the sinus: stamens numerous, half as long as the petals. Marysville 

 Buttes southward. 



Li. Isevicaulis is perhaps always found on the flood beds of streams. Its flowers 

 have narrow petals, lacking the satiny luster which marks the other large flowered 

 species.
