508 IIYDROPHYLLACE^. • Phacelia. 



7. P. tanacetifolia, Bonth, Erect, 1 to 3 feet high, ronghish-hiisute or hispid : 

 leaves D- 17 dividetl into linear or oblong-liuciir ouee or twice piiiiiately-purLed or 

 cleft divisions, all aessilo or nearly so; the lohes small and mostly linear ol)loiig : 

 spikes cymosely chistered, 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. Keg. t. 1G9G ; Brit. ¥\. Chad. ser. 2, t. 3G0 ; Hook. 

 Bot. ilag. t. 3703. 



Sandy or gi-ivelly banks of streams, &c., tlnougliout the western part of the State. Generally- 

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

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

 very fine-leaved state. 



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

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

 5 -7-divided or parted into oblong or even linear pinnatilid-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. J\ lauuctti/olia, var. luti/olia, Thurber in Bot. Mex. 

 Bound. 143. 



Var. hispida, (iray, 1. e. 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-linear to more broadly 

 spatulate, in fruit sometimes half an inch long. 



D17 ground, apparently from San Fianciseo 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, Xuntas, Torrcy, 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-tlowered, 

 the short i)edicels ascoiKling iji fruit : stamens and commonly the style not surpass- 

 ing the more o])en or almost rotate corolla : calyx-lobes from linear-lanceolate to 

 ovate, thin, bristly only or chielly along their edges (whence the specilic name). 



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

 if constant, should mark this sjjccies. 



V. PHVLLOMANICA, Gray, is a remarkable new species of this subdivision, most j)eculiar in 

 having all or a part of tlio sepals pinnatitid or trilid and foliaceous ; and the j)ube3i;enco is very 

 soft. It was discovered ou (Juadalupo Islanil, Lower California, by Dr. E. I'alnur. 



§ 2. Ovules and seeds several oi' numerous to each placenta, the latter not transversely 

 corrugated : tube of the corolla aj^pendac/ed ivith 10 internal vertical plates or 

 lamellce in pairs. — Eutoca, Gray. {Eutoca, 11. Brown.) 



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



+■ Perennial, silky -pubescent or canescent : leaves once to thrice 2>innatijid. 



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

 with numerous narrow ami mostly linear lobes : (lowers 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 8])ecies); the in- 

 ternal appendages oblong and free from the stamens : style 2-ch:ft at the ajiex ou]y : 

 seeds 12 to 18, ribbed and reticulated. — Amer. Jour, ycience (18G2), xxxiv. 254;; 

 Watson, ]>ot. King Exp. 252, Kutoca saricea, (Jraham; Bot. Mag. t. 3003. 



In the higher mountiiins 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.
