Phacelia. HYDROPHYLLACE^E. 513 



the upper entire : racemes loosely few-flowered ; short pedicels spreading : funnel- 

 form corolla (3 or 4 lines long) fully twice the length of the linear calyx-lobes ; 

 the appendages small and obscure : capsule ovoid, 6 - 8-seeded. Watson, 1. c. 

 Reese River Valley, Nevada, Watson. Not unlikely to be also Californian. 



4. Like 2, but no appendages within the rotate-campanulate corolla or on the base 

 of the filaments : ovules and seeds very numerous on the dilated placenta?, the 

 latter pitted : very glandular annuals. GYMNOBYTHUS, Gray. 



31. P. viscida, Torr. A foot or two high, branching and hirsute at base, very 

 glandular-viscid above : leaves ovate or obscurely cordate, doubly and irregularly 

 toothed or incised, an inch or two long : flowers in loose racemes : corolla deep blue 

 with purple or pale centre (sometimes white), from 6 to 10 lines broad, about the 

 length of the very slender filaments : style 2-parted : capsule ovate, abruptly pointed.

Var. albiflora, Gray (Eutoca albiflora, !Nutt.), is a white-flowered form, other- 

 wise similar. 



Open grounds near the coast, from Santa Barbara southward. 



32. P. grandiflora, Gray, 1. c. Very like the preceding, perhaps more hispid 

 at the base of the stem ; but the light blue or white almost rotate corolla about 

 double the size. Eutoca grandiflora, Benth. 1. c. E. speciosa, Nutt. PI. Gainb.

5. Like 4, but with a small truncate or emarginate scale adnate to the inner base 

 of each capillary exserted filament : style 2-cleft above the middle: corolla either 

 oblong-campanulate or open-campamdate : glandular annuals. WHITLAVIA, 

 Gray. 



* Corolla open-campanula te : ovules and seeds not very numerous. 



33. P. Parryi, Torr. 1. c. A span or two high, hirsute or even hispid as well 

 as glandular-viscid : leaves ovate, irregularly doubly toothed or laciniate, or the 

 lowest pinnately parted, the upper cauline longer than their petioles : racemes very 

 loose, at length elongated : pedicels widely spreading, slender (from half to a full 

 inch long) : corolla cleft beyond the middle, deep violet with a yellowish or white 

 5-rayed eye, half an inch long, about twice the length of the narrow calyx-lobes : 

 rilaments bearded, a little exserted : ovules 20 or 30 to each placenta. 



Near San Diego and Los Angeles, Parry, Cooper, &c. 



34. P. longipes, Torr. Apparently low, slender, loosely branched, glandular 

 and slightly hispid (base of the stem iinknown) : cauline leaves round-oval or 

 cordate, coarsely and obtusely 5 - 8-toothed (half an inch long), shorter than their 

 petioles : racemes very loose : corolla hardly half an inch long, apparently white, 

 5-cleft to the middle, nearly twice the length of the spatu late-linear sparsely hispid 

 calyx-lobes: style rather deeply 2-cleft: ovules only 8 or 10 to each placenta: seeds 

 few. Gray, 1. c. 322. 



Santa Barbara Co., Torrcy. No one else has yet met with it. 



* * Corolla oblong-campanulate, the tube cylindraceous-ventricose : ovules and seeds 

 very numerous on tlie dilated placentae. ( Whitlavia, Harvey.) 



35. P. Whitlavia, Gray. About a foot high, loosely branching, hirsute and 

 glandular : leaves ovate or deltoid, obtusely and incisely toothed, longer than the 

 petiole : raceme loose and elongating : tube of the violet (or rarely white) corolla an 

 inch or so long, twice or thrice the length of the rounded lobes and of the narrow 

 calyx-lobes : stamens conspicuously exserted. Whitlavia grandiflora, Harv. in
