364 LABIATiE. Pogogyne. 



uously bilabiate calyx oblong-campanulate ; the teeth especially hispid or hirsute with 

 long whitish hairs ; those of the broad upper lip short .and deltoid; the two of the lower 

 aristiforni subulate, equalling the tube of the purple and spotted corolla : fertile stamens 

 equalling the emarginate upper lip of the corolla ; sterile filaments subulate, sometimes 

 with small rudiments of anthers. — Gray, 1. c. ; Chapm. in Bot. Gazette, iii. (1878), 10. — 

 Low pine barrens, W. Florida, Chapman. From the name the species apparently is not 

 sweet-scented. 



24. P0G-6GYNE, Benth. (Tlcoyoov, beard, yvv/j, female ; the style bearded.) 

 — Califoruian annuals, of low stature, sweet-aromatic ; with oblong-ovate or ob- 

 lanceolate mostly entire leaves, the lower narrowed into a petiole, the upper 

 diminished into bracts, these and the calj^x usually conspicuously ciliate-bearded 

 with hirsute or hispid hairs. Flowers verticillastrate-glomerate and sessile, at least 

 the upper glomerules spicate or capitate. Calyx-teeth mostly 3-nerved. Corolla 

 blue or violet purple, sometimes paler. Fl. spring and summer. — Benth. Lab. 

 414, & DC. I.e. 243 ; Gray in Bot. Calif, i. 596. 



§ 1. Stamens all four with perfect anthers: style conspicuously bearded above ; 

 its subulate lobes or stigmas almost equal : corolla 6 to 9 lines long, with funnel- 

 form tube, and throat surpassing the (variable) calyx. 



* Inflorescence oblong- or cj-Iindrical-spicate and nearly continuous, conspicuously white-hirsute or 

 hispid witli the long and rigid marginal hairs of the bracts and calyx. 



P. Douglasii, Benth. 1- c. Rather stout, a span to a foot high : leaves spatulate-oblong 

 or narrower, veiny, rarely dentate : bracts linear, acute : flowers comparatively large, blue 

 or violet ; lower calyx-lobes twice the length of the tube, much longer and narrower than 

 the others. — Hook. Bot. JNIag. t. 5886 ; Gray, Bot. Calif, i. 597. P. mullijiom, Benth. I. c, 

 is merely a smaller form, with rather shorter bracts. — California, through the foothills of 

 the Sierra and westward. 



P. parviflora, Benth. 1. c. More slender and lower : leaves narrower : spike shorter : 

 bracts mostly obtuse : corolla barely half inch long : lower calyx-lobes hardly longer and 

 the upper ones shorter than the tube. — From San Francisco Bay northward, Douylas, 

 Bolander, &c. 



* * Verticillastrate clusters more or less distant: bracts and calyx inconspicuously hirsute-ciliate : 

 anthers of posterior stamens smaller but polliniferous. 



P. nudiuscula, Gray. A span to a foot high: branches slender, puberulent: leaves 

 spatulate or narrower, obtuse, not over an inch long, glabrous : bracts linear-subulate and 

 cuspidate : corolla only half inch long, about twice the length of the calyx : lobes of the 

 latter lanceolate- or linear-subulate and cuspidate. — Bot. Calif, i. 597. — Near San Diego, 

 D, Cleveland. 



§ 2. Hedeomoides, Gray, 1. c. Posterior stamens sterile : style sparingly 

 hairy, its lobes very unequal : flowers smaller, some of the lower ones often dis- 

 tant and solitary or nearly so in the axils of ordinary leaves. 



P. TENuiFLORA, Gray, Proc. Am. Acad. xi. 100, of Guadalupe Island off Lower California, 



has tlie tube of corolla longer than the calyx, as in the preceding section. In the following 



species the corolla is only 2 lines long, and at least its tube included. 



P. ziziphoroides, Benth. Stem 2 to 6 inches high : leaves ovate or oval, thickish ; 

 uppermost, with the rigid narrow bracts and calyx, hirsute-ciliate with strong and wiiite 

 bristly hairs : inflorescence capitate or short-spicate : cal3^x-lobes slightly unequal, broadly 

 lanceolate, very acute, hardly twice the length of the tube, the longer about equalling 

 the corolla : posterior filaments as large as the anterior, but their anthers abortive. — 

 PI. Hartw. 330 ; Gray, Bot. Calif. 1. c. — Valley of the Sacramento River, Ilartweg, Andrews, 

 Bolander. 



P. serpylloides, Gray. Stems slender, branched from the base, ascending or at length 

 diffuse, 3 to 6 incites high: leaves obovate-oval or spatulate, 3 or 4 lines long; the lower 

 distant, most of them single- or few-flowered in the axils ; upper more floriferous, approxi- 

 mate and becoming bracts to the oblong or often longer and much interrupted spike ; the
