 slightly surpassing the purple corolla : ovules only 4 or 5 to each placenta. — South-eastern 

 California, on the Mohave Eiver, May, 1876, Palmer. Habit somewhat of P. Menziesii, 

 but lower, more diffuse, less hispid, and with different appendages to the corolla, tliis fully 

 4 lines long. 



Var. exilis, a slender form, more erect : leaves and calyx-lobes all linear and slightly- 

 broader upward : corolla only 3 lines long : seeds as in the next species. — Bear Valley on 

 the Mohave slope of the San Bernardino Mountains, California, Pang & Lemmon. 

 P. grisea, Gray. A span or two high, more cinereous with a sparse hirsute and a close 

 finer pubescence, rather stout : leaves ovate or oblong : spikes more densely hirsute or 

 even hispid, at length i to 6 inches long, densely flowered : calyx-lobes obovate-spatulate, 

 little exceeding the capsule : corolla nearly white : filaments and 2-clef t style conspicuously 

 exserted ; the former minutely and sparsely retrorsely papillose or hirsute : ovules 5 or 6 

 to each placenta : seeds coarsely alveolate. — Proc. Am. Acad. xii. 80. — W. California, on 

 Pine Mountain, back of San Simeon Bay, Palmer, 1876. 



++■ *H- Taller, setose-hispid : leaves pinnatifid and incised, petioled : appendages to the corolla 

 large, free and pointed at apex. 



P. loasaef olia, Torr . A foot high, somewhat viscid-pubescent as well as hispid with long 

 and stiff spreading bristles : leaves ovate or oblong, rarely subcordate, more or less pin- 

 natifid, and the lobes acutely toothed or incised : spikes geminate : corolla short-campanu- 

 late (3 lines long), little exceeding the linear-spatulate calyx-lobes ; its internal appendages 

 transverse and auriculate-incurved, with the free apex acuminate or cuspidate : naked fila- 

 ments and 2-parted style conspicuously exserted : ovules 6 to 9 on each placenta : seeds 

 angled, alveolate. — Bot. Mex. Bound. I.e. ; Gray, Proc. Am. Acad. x. 323, & Bot. Calif, 

 i. 509. Eutoca loasavfolia, Benth. 1. c. — California, near Monterey, Douglas, Parry. Little 

 known, in aspect between P. malvcefolia and P. ramosissima. 



•t— 4— Root probably perennial : scorpioid inflorescence at length open and geminate-racemose : 

 ovules and seeds about 50 on each dilated placenta: stamens hardly surpassing the very open 

 corolla : leaves conspicuously petioled, incised. 



P. Bolanderi, Gray. Hispid with slender bristles, also viscid-pubescent, especially 

 above : stem stout, erect, a foot or two high, freely branching : radical and lower cauline 

 leaves lyrate and oblong in outline, with one or two pairs of small and incised lateral divi- 

 sions ; the terminal division and the short petioled upper leaves ovate or oval (2 or 3 inches 

 long), coarsely incised or lobed, truncate or subcordate at base : corolla nearly rotate when 

 expanded and almost an inch in diameter, white ; its appendages semi-obovate, almost as 

 broad as long, distinctly connected at base in front of the adnate and sparingly bearded 

 filaments: anthers oblong: style cleft nearly to the middle: capsule broadly ovate, acute, 

 shorter than the lanceolate or at length spatulate lobes of the calyx. — Proc. Am. Acad. 

 x. 322, & Bot. Calif, i. 509. — Cottonaby Creek, 20 miles north of Noyo, Mendocino Co., Cali- 

 fornia, Bolander. Lowest leaves 4 inches long, exclusive of the petiole. Cymes once to 

 thrice forked ; the short racemes at length open : pedicels 1 or 2 or sometimes the lower 

 3 lines long. Calyx 3 or at length 4 lines long, decidedly shorter than the ample corolla. 



4- H— -H- Root perennial : spikes of the congested cyme once to thrice geminate or crowded at 

 the summit of a terminal peduncle, short and densely-flowered : ovules and seeds rather few : 

 appendages of the corolla very broad and obtuse : stamens and style conspicuously exserted : 

 anthers linear or oblong : leaves all petioled, incisely lobed. 



P. hydrophylloid.es, Torr. A span or two high from slender subterranean shoots 

 proceeding from a thickened stock or root, canescently pubescent, and above hirsute or 

 hispid as well as glandular : leaves silky-pubescent both sides, slender-petioled, ovate or 

 rhomboidal, an inch or two long, obtuse, incisely few-toothed or lobed, or sometimes the 

 lowest lyrate, having one or two nearly detached small basal lobes or divisions : short 

 spikes or racemes of the glomerate cyme not elongating : corolla violet-blue or whitish ; 

 its appendages semi-oval, united at base with that of the naked filament : anthers short- 

 linear : style almost 2-parted : capsule about the length of the calyx, abruptly mucronate- 

 pointed : seeds 6 to 8, angled. — Gray, Proc. Am. Acad. vii. 400, x. 323, & Bot. Calif. 1. c — 

 Dry sandy or gravelly soil in the Sierra Nevada, California, at 5-9,000 feet, from Mariposa 

 to Sierra Co., Brewer, Bolander, Lemmon, &c. Corolla 3 or 4 lines long: the appendages as 

 in the following species, but hardly connected in front of the base of the filament.
