508 HYDROPHYLLACE.E. Phacelia. 



7. P. tanacetifolia, Benth. Erect, 1 to 3 feet high, roughish-hirsute or hispid : 

 leaves 9 1 7-divided into linear or oblong- linear once or twice pinnately- parted or 

 cleft divisions, all sessile or nearly so ; the lobes small and mostly linear- oblong : 

 spikes cymosely clustered, at length elongated ; the very short pedicels ascending 

 or erect : corolla light violet or bluish : stamens and style usually very much 

 exserted : calyx-lobes linear or linear-spatulate, not twice the length of the oval 

 or oblong-oval capsule. Bot. Reg. t. 1696 ; Brit. Fl. Gard. ser. 2, t. 360; Hook. 

 Bot. Mag. t. 3703. 



Sandy or gravelly banks of streams, &c., throughout the western part of the State. Generally 

 well marked by its much dissected Tansy-like foliage, which gives the specific name : this is 

 particularly applicable to the form called by Thurber var. tenuifolia (Bot. Mex. Bound. 143), a 

 very fine-leaved state. 



8. P. ramosissima, Dougl. Divergently branched or straggling, below merely 

 pubescent or hispid, above hispid and commonly glandular-viscid : leaves pinnately 

 5 - 7-divided or parted into oblong or even linear pinnatiiid-incised divisions : spikes 

 clustered and elongating little in age, the short pedicels soon horizontal : stamens 

 and style moderately exserted : calyx-lobes from linear or spatulate to obovate, more 

 than twice the length of the almost globular capsule. Benth. in Linn. Trans, 

 xvii. 280 ; Hook. Fl. ii. 80. P. tanacetifolia, var. latifolia, Thurber in Bot. Mex. 

 Bound. 143. 



Var. hispida, Gray, 1. c. Conspicuously bearded with long and white spreading 

 bristles, like Borrage, especially the spikes, which are more open and racemose in 

 fruit, sometimes elongated : calyx-lobes from narrow spatulate-liuear to more broadly 

 spatulate, in fruit sometimes half an inch long. 



Dry ground, apparently from San Francisco Bay to the southern limits of the State, and in all 

 the dry regions east of the crests of the Sierra Nevada, whence it ranges far northward and 

 southward, passing into the foregoing. The var. hispida, a striking and less known form, if 

 not distinct species, occurs from Santa Barbara southward, Nuttall, Xantus, Torrey, Cleveland. 



9. P. ciliata, Benth. 1. c. A span or two high, resembles depauperate or low 

 forms of the two preceding with less dissected foliage : leaves rarely divided but much 

 incised or cleft and toothed : spikes simple or in pairs, at length loosely-flowered, 

 the short pedicels ascending in fruit : stamens and commonly the style not surpass- 

 ing the more open or almost rotate corolla : calyx-lobes from linear-lanceolate to 

 ovate, thin, bristly only or chiefly along their edges (whence the specific name). 



Near the coast, from San Francisco Bay and the Sacramento southward. The included stamens, 

 if constant, should mark this species. 



P. PHYLLOMANICA, Gray, is a remarkable new species of this subdivision, most peculiar in 

 having all or a part of the sepals pinnatifid or tritid and foliaceous ; and the pubescence is very 

 soft. It was discovered on Guadalupe Island, Lower California, by Dr. E. Palmer. 



2. Ovules and seeds several or numerous to each placenta, the latter not transversely 

 corrugated: tube of the corolla appendaged with 10 internal vertical plates or 

 lamellae in pairs. EUTOCA, Gray. (Eutoca, E. Brown.) 



* Stamens and style capillary and much longer than the open-camjmmdate corolla. 

 -t- Perennial, silky-pubescent or canescent : leaves once to thrice pinnatifid. 



10. P. sericea, Gray. A span or two high : stems simple, rather leafy : leaves 

 with numerous narrow and mostly linear lobes : flowers much crowded in a narrow 

 spike-like cluster : corolla violet-blue or sometimes whitish, cleft to the middle, 

 persistent in fruit around the base of the capsule (as in no other species) ; the in- 

 ternal appendages oblong and free from the stamens : style 2-cleft at the apex only : 

 seeds 12 to 18, ribbed and reticulated. Amer. Jour. Science (1862), xxxiv. 254; 

 Watson, Bot. King Exp. 252. Eutoca sericea, Graham ; Bot. Mag. t. 3003. 



In the higher mountains of Nevada (as well as in the Rocky Mountains), also in the south- 

 eastern borders of Oregon, and thence northward ; therefore probably in the northern sierras of 

 California,
