Synthyris. SCROPIIULARIACE^E. 285 



23. C APR/ARJ A, L. ( Caprarius, relating to goats, i. e. Goat-weed. - 

 Tropical American herbs or undershrubs ; with rather small white or flesh-colored 

 flowers, on slender often geminate pedicels, in the axils of the alternate serrate 

 leaves. One species barely reaches our southern border. 



C. biflora, L. Stiff ruticose, 2 to 4 feet high, pubescent or glabrous : leaves oblong-lanceo- 

 late, sharply serrate above the middle : sepals linear-subulate, equalling the capsule. 

 Key West, and S. Texas on the coast; the glabrous form, mostly 5-androus, C. Mexicana, 

 Moricand in DC. (Tropical shores.) 



24. SY"NTHYRIS, Benth. (From GVV, together, and Ovmg, little door or 

 valve, the valves of the capsule long adhering below to the short placeutiferous 

 axis.) W. North American perennials, nearly related to Wulfenia of S. E. 

 Europe and the Himalayas ; but the anther-cells not confluent and seeds discoidal. 

 Leaves largely radical and petioled ; those of the simple stem or scape and the 

 bracts all alternate. Flowers small, purplish or flesh-color, in a simple spike or 

 raceme ; in summer. Stamens inserted close to the sinuses of the corolla. DC. 

 Prodr. x. 454, & Gen. ii. 963. 



1. Ovules and seeds only a pair in each cell, on a short partition : capsule 

 divaricately 2-lobed ; the cells transversely oblong : seeds with thickish margins 

 incurved at maturity : acaulescent, with naked scapes. 



S. rotundifolia. Rootstock short and creeping, bearing a tuft of cordate-orbicular doubly 

 crenate or crenate-incised leaves (glabrous or slightly hairy), and weak scapes hardly 

 exceeding the petioles (3 or 4 inches long) : pedicels of loose short raceme longer than the 

 bluish flowers (about half inch long): sepals spatulate : corolla campanulate. S. reni- 

 formis, Gray, Bot. Calif, i. 571, chiefly, not Benth. Oregon, in shady coniferous woods of 

 the Columbia and Willamette, Nuttall, E. Hall; and probably first collected in woods N. E. 

 of Fort Vancouver by Gairdner. 



Var. cordata, a form with smaller and thicker almost simply crenate leaves of cord- 

 ate outline. S. renifonnis, var. cordata, Gray, I.e. Gravelly hillsides, Mendocino Co., 

 California, Kelloijij & Harfvrd. 



2. Ovules and usually seeds several or numerous in each cell: capsule merely 

 emarginate : seeds plane or meniscoidal, thin-edged. 



# Flowers racemose rather than spicate : leaves of the preceding section : capsule orbiculate, much 

 compressed, acute-edged. 



S. reniformis, Benth. 1. c. A span or so high : leaves orbicular-reniform, crenate and 

 crenately somewhat incised, an inch or two in diameter : surpassed by the somewhat 

 bracteate slender scape : pedicels mostly shorter than the bluish flowers : capsule trun- 

 cate-emarginate. Wulfenia reniformis, Dougl. in Hook. Fl. ii. 102, t. 71. (Fig. 3 repre- 

 sents the capsule much too long and too turgid.) Oregon and Washington Terr. " Grand 

 Rapids of the Columbia and Blue Mountains," Douglas. 



Var. major, Hook. Leaves of thicker texture and with multilobulate margin, the 

 lobelets crenate: raceme spicifonn : capsule strongly emarginate. Kew Jour. Bot. v. 257. 

 Idaho. Fertile northerly slopes of snowy mountains, highlands of Nez Percez, Geyer,'m 

 fruit. Porphyry Peak, Prof. Alarcy, in flower. 



* * Flowers in a dense spike terminating a stouter and more or less brarteate or leafy scape or 

 stem: rootstock or caurtex short, thiekish, not creeping: capsule turgid, from short-oval to ellip- 

 tical, slightly emarginate or retuse. 



-i Leaves laciniately cleft or divided, all radical : corolla cylindraceous, considerably longer than 



the calyx. 4-cleft to the middle. 



S. pinnatifida, Watson. Tomentulose-pubescent and glabrate : leaves slender-peti- 

 oled, from round-reniform to oblong in circumscription, from palmately to pinnately 3-7- 

 parted or below divided, and the divisions again laciniately cleft or parted : scape spar- 

 ingly bracteate, a span high : spike narrow : flowers subsessile : corolla whitish. Bot.
