PHACELIA FAMILY. 339 



ecological forms. Var. pulchella Chandler. Distinguished by the minute or 

 even obsolete calyx-appendages, and the rotate-campanulate deep blue corolla; 

 scales linear, ciliate. — Foothills of the southern Sierra Nevada, rare (N. pul- 

 chella Eastw.). 



3. ELLISIA L. 

 Annuals, similar to Nemophila and scarcely separable. Leaves opposite or 

 the uppermost alternate, pinnately parted or twice or thrice pinnately dis- 

 sected. Flowers bractless, in axillary peduncled racemes. Calyx without ap- 

 pendages at the sinuses, and usually much enlarged under the fruit. Corolla 

 white, campanulate, shorter or little longer than the calyx, the internal 

 appendages minute or none. Ovules 4 to 8. Seeds not carunculate. (John 

 Ellis, English botanist of the 18th century, whom Linnaeus called a "bright 

 star of natural history.") 



Leaves once pinnately parted; ovules 4, borne on the front of the placentae 



1. E. membranacea. 



Leaves twice to thrice pinnatifid; ovules 8, 2 on the front and 2 on the back of each 



placenta 2. E. chrysanthemifolia. 



1. E. membranacea Benth. Stems procumbent, 1 to 2 ft. long; herbage 

 glaucous, the leaves with a few short scattered stiff hairs, the stems with minute 

 prickles on the angles; leaves pinnately divided, with 2 broad lobes (obtuse at 

 apex and broadest at base) spreading at right angles to the terminal lobe, or 

 often with 4 to 8 similar lateral lobes; petiole wing-margined; flowers racemose, 

 few or many on the peduncles; calyx without appendages, its lobes ciliate- 

 bristly; corolla white with a small lance-shaped purple spot in the center of 

 each lobe, 2 lines broad, no scales in the throat but with 10 glandular elevations; 

 capsule with several muricate prickles, 1 or 2-seeded; seed globose, reticulated. 



Shady places in the foothills: Santa Clara Co., Mt. Diablo and Tulare 

 southward to Southern California. Mar.-Apr. 



2. E. chrysanthemifolia Benth. Stem erect, freely branching, 1 to 2 ft. 

 high ; leaves twice to thrice pinnately dissected ; flowers loosely racemose ; 

 corolla open-campanulate, surpassing the oval calyx-lobes; the placentae line 

 and exactly conform to the valves; two roughened seeds are borne on the front 

 of each placenta, and smooth ones are concealed behind each placenta, that is, 

 between the placenta and the valve. 



Shady ground: San Francisco Bay to Southern California. 



4. PHACELIA Juss. 

 Perennial or annual herbs of marked aspect, with alternate leaves. Flowers 

 blue or white, in scorpioid spikes or racemes. Calyx of 5 nearly distinct sepals, 

 commonly accrescent. Corolla from nearly rotate to campanulate, tubular or 

 funnelform, promptly deciduous, the tube commonly with internal lamellate 

 projections or appendages. Stamens inserted on the base of the corolla. Style 

 2-cleft. Capsule 1-celled or nearly or quite 2-celled by the approximation or 

 union of the placentae in the axis, 2-valved, the thin septa-like placentae adher- 

 ent to the valves. Seeds reticulate-pitted or favose. (Greek phakelos, a cluster, 

 many species with crowded flowers.) 



A. Ovules 4 or more on each placenta; capsule not less than 6-seeded; stamens shorter than 

 (rarely equaling) the corolla; annuals. 

 Corolla-tube without internal scales or appendages. 



Leaves pinnatifid; corolla open-campanulate, twice the length of the calyx 



1. P. douglasii. 

 Leaves entire or mostly so. 



Corolla narrow, 3 lines long or less, little larger than the calyx... 2. P. circinatifoniiis.
