forming a head-like bunch, not elongating in fruit, terminating 

 the stems, with peduncles distinct. Divisions of the calyx nar- 

 rowly-linear, very hispid, as long as the corolla tube. Corolla 

 violet-blue, open-bell-shaped, hispid externally, smooth within, 

 lobes rounded, appendages extending from the insertion of the 

 stamens almost to the throat, free at top. Stamens and style ex- 

 serted ; filaments smooth ; style deeply 2-parted, hairy below the 

 divisions. Pod elliptical, tipped with a short point, viscid pubes- 

 cent, about as long as the calyx ; seeds m.any, rich chestnut 

 brown, glossy, irregularly angled, finely pitted. Converse Basin, 

 Millwood. 



Phacelia Eisenii Brandegee. Annual, 1-3 in. high, branch- 

 ing from the base, clothed with stiff hairs. Leaves elliptical to 

 oblong, on petioles of almost equal length, together about an 

 inch, entire, obtuse. Flowers in short racemes on hair-like pedi- 

 cels. Calj'x with narrow, linear-oblanceolate divisions, becoming 

 very narrow towards the base, unequal, twice as long as the pod. 

 Corolla blue, open-bell-shaped, somewhat surpassing the calyx. 

 Stamens and pistil not exserted, smooth. Pod ovoid, pointed, 

 minutely hairy ; seeds 2, pitted. 



Phacelia Purpusii Brandegee. Annual, a few inches to 

 more than a foot high, branching, hairy and glandular. Leaves 

 oblong to ovate, an inch or two long, including the short petioles, 

 3-nerved from the base, obtuse or acute. Flowers all on one side 

 of the spicate racemes, which sometimes lengthen to 8 in. in fruit ; 

 pedicels short. Calyx with leaf-like, spatulate to obovate divi- 

 sions, tapering to a thread-like base, unequal, enlarging in fruit. 

 Corolla violet, open-bell-shaped, a little longer than the calyx ; 

 appendages long, united at the base of the stamens. Stamens 

 somewhat bearded at base, together with the 2-cleft style extend- 

 ing beyond the corolla. Pod hairy, pointed ; seeds generally 6,

 green, not canescent. Leaves simple or compound ; when the 

 latter, with the upper leaflet much the larger, acute ; petioles as 

 long as the blades, together 3-5 in. Spikes from the upper axils, 

 generally branched, peduncled, strongly scorpioid, elongating in 

 fruit. Flowers on short, hair-like pedicels. Calyx with narrowly- 

 linear divisions spreading slightly, dilated at the top, twice as long 

 as the pod. Corolla pale lilac to white, tubular, with the divi-
