 fjrandiJiorus,A.T)C. I.e. — California, from Santa Barbara Co. southward, i^owr/Zas, 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- 

 ginate 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 (purple or blue, varj'ing to white in cultivation), with tube longer than the rounded 

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

 Whillavia, Harvey. 



P. W^hitlavia, 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. — Whillavia 

 grand/flora (and IV.iriinor), Harvey in Lend. 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; otiierwise much resembles the 

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

 San Diego Co., Ckfdand. 



* Corolla rotate-campanulatc, deeply-lobcd, hardly twice the length of the narrow calyx-lobes : 

 racemes very loose: pedicels filiform, widely spreading: 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 laciniatc, 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 eacli 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, 

 Torrei/. 



§ 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 Euphacelice, 

 &c.,only by the ovules and seeds.) — Man. ed. 2, 320, & Proc. Am. Acad. x. 322. 

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



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

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

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

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



-I— Eoot annual : spikes solitary terminating the branches, or geminate : ovules only 4 to 9 on each 

 placenta: anthers oval. 



++ Low, a span or more high, diffuseh' 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 sunnuit : 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 :
