 nrandijlorus, A.BC. I.e. — California, from Santa Barbara Co. sonthwa.Td, Douglas, Nuttall, 

 Peckham, &c. Capsule 4 lines long, the cuspidate persistent and indurated base of the 

 style a line in length. 



§ 5. WhitlXvia, Gray. Ovules and seeds numerous or rather few ; the testa 

 favose-pitted : appendages of the corolla reduced to 5 small truncate or emar- 

 ffinate scales, one adnate to the inner base of each capillary somewhat exserted 

 filament : style 2-cleft above the middle : Californian annuals, with inflorescence 

 and habit of the preceding section, but less glandular, and with longer petioles and 

 pedicels, and looser racemes, the flowers showy. — Proc. Am. Acad. x. 321. 



* Corolla large (violet-purple, varying to white in cultivation), with tube longer than the rounded 

 lobes and much longer than the liuear calyx-lobes: placentae and seeds of preceding section. — 



Whitlavia, Harvey. 



P. "Whitlavia, Gray, 1- c. About a foot high, loosely branching, hirsute and glandular : 

 leaves ovate or deltoid, incisely toothed : corolla with cylindraceous ventricose tube usually 

 an inch long, thrice the length of the lobes : appendages to the filaments hairy. —Whitlavia 

 grandifiora (and W. minor), Harvey in Lond. Jour Bot. v. 312, 1. 11, 12; Bot. Mag. t. 4813. 

 — S. California, Coulter, &c. Cultivated as an ornamental annual. 



P. campanularia. Lower : leaves subcordate, less deeply dentate : tube of the truly 

 campanulate corolla half inch long, expanded at throat, barely twice the length of the 

 lobes: appendages to the filaments glabrous and smaller; otherwise much resembles the 

 preceding, and almost as showy. — S. California, San Bernardino Co., Parry and Lemmon. 

 San Diego Co., Cleveland. 



* Corolla rotate-campanulate, deeply-lobed, hardly twice the length of the narrow calyx-lobes : 

 racemes very loose ; pedicels filiform, widely spreadmg : herbage hirsute or somewhat hispid and 

 glandular. 



P. Parryi, Torr. A span or two high, rather slender : leaves ovate. Irregularly and in- 

 cisely doubly toothed or laciniate, or the lowest sometimes pinnately parted ; the upper 

 cauline longer than their petioles : corolla cleft beyond the middle, deep violet, two-thirds 

 inch in diameter: filaments bearded : ovules on each placenta 20 or 30 and seeds 15 to 20. 



Bot. Mex. Bound. 144 ; Gray, 1. c. — California, near Los Angeles and San Diego, Parry, 



Cooper, Davidson, &c. 



P. longipes, Torr. Slender, loosely branched : cauline leaves roundish-oval or subcor- 

 date, coarsely and obtusely 5-8-toothed, about half inch long, all shorter than the petioles : 

 corolla hardly half an inch long, apparently white, 5-cleft barely to the middle ; ovules on 

 each placenta 8 or 10, and the seeds fewer — Gray, 1. c. — Santa Barbara Co., California, 

 Torrey. 



§ 6. EuTOCA, Gray. Ovules and seeds several (6 to 12) or more numerous 

 on each placenta ; the testa areolate-reticulated or favose-pitted, but not trans- 

 versely rugose: appendages of the mostly campanulate corolla in the form of 

 10 vertical salient lamellae: capsule ovate or oblong. (Chiefly occidental, one or 

 two boreal ; habit very various, several distinguished from analogous Eaphaceli(E, 

 &c.,ouly by the ovules and seeds.) — Man. ed. 2, 329, «fe Proc. Am. Acad. x. 322. 

 Eutoca, R. Br., excl. spec, Eutoca § Ortheutoca, A.DC. 



* Perennials, or annuals, with conspicuously (in P. Bolanderi and P. Mohavensis more slightly) 

 exserted stamens and dense scorpioid inflorescence : appendages of the open-campanulate corolla 

 conspicuous and usually broad, more or less oblique, at base united in pairs with or across the 

 base of the filament, forming a kind of sac behind it. 



-t- Root annual : spikes solitary terminating the branches, or geminate : ovules only 4 to 9 on each 

 placenta: anthers oval. , . 



++ Low, a span or more high, diffusely branched, merely hirsute and with finer somewhat viscid 



pubescence : leaves from ovate-oblong to linear-lanceolate, entire or rarely 1-2-toothed or incised, 



tapering at base into a short petiole: appendages to the corolla elongated-oblong and adnate up 



to the truncate summit : capsule ovate, acute. 



P. Mohavensis. Barely a span high : leaves lanceolate or the lowest linear-oblong 



(about an inch long) : racemes at length an inch or two long and strict : short pedicels erect :
