PLANTS COLLECTED BY DR. GAMBEL. 159 



placentas presents the large circular cavity of the capsule, as if merely one-celled, 

 with two hemispherical valves ! Seed with a corneous, large albumen ; embryo 

 straight, minute, central, not half the length of the albumen. Annuals with 

 bipinnatifid leaves, and the flowers in loose racemes. 



E. *PANicuLATA. O- Flowers in a loose terminal panicle; stem viscid; uppermost leaves pinnatifid, 

 segments of the calyx oval, obtuse. 



About one to two feet high, somewhat hairy and viscid. The leaves bipinnatifid ; 

 the segments short, and toothed bluntly. Flowers small, yellowish-white, rather more 

 than the length of the calyx, disposed in loose, naked, terminal racemes, with long 

 peduncles. Calyx cup-shaped, increasing with the fruit; the segments oval and 

 obtuse. Corolla pubescent, tubular-campanulate, shortly 5-cleft, before opening, with 

 three of the segments external. Stamens equal, with slender filaments; anthers 

 small and oval ; style longer than the germ, with a very short bifid stigma. Capsule 

 depressed, globose, apparently 1-celled, each of the placentas becoming adnate to the 

 sides of the valves, with about four rugose seeds, two to four other even, elliptic seeds 

 concealed behind the placental lamina, one or two behind each. The rugose 

 epidermis of the seed swells up into a pulpy mass on being moistened. 



Hab. Island of Santa Catalina, Upper California. Flowering in March and April. 



E. *FOLiosA. Leaves all bipinnatifid, hirsute; racemes not longer than the leaves; segments of the calyx 

 ovate, acute. 



Hab. With the above, which it much resembles, but a lower, less viscid plant, 

 with rather smaller flowers and capsules. 



COLLOMIA. 



§. *PiCRAC0LLA. Calyx obconic, scarcely cleft to the middle, with foliaceous 

 segments. Flowers racemose, scattered. Intensely bitter to the taste. 



C. *LiNoiDES. Leaves narrow-linear, scattered, ending in a short mucro ; flowers small, scattered, 

 subsessile, the calyx shorter than the tube of the corolla. 



Hab. Banks of the Platte. (Nuttall.) 



PHACELIA. 



P. *CANESCENS. Canesceut and hirsute ; leaves spathulate, oblong or sublanceolate, entire ; racemes 

 condensed into circinate clusters ; corolla twice the length of the calyx ; stamens exserted, the 

 filaments pilose. 



A perennial dwarf species, about a span high, with many stems from the same root. 

 Radical leaves whitely and densely pilose, with two sorts of pubescence, rather silky. 

 Radical leaves two to three inches long, by three-fourths of an inch in width, on
