364 LABIATE. Pocjogyne. 



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

 long wliitish 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, I. c. ; Chapm. in Bot. Gazette, iii. (1878), 10. — 

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

 sweet-scented. 



24. P0G-6G-YNE, Benth. {Uajoiv, beard, yvvi], female ; the style bearded.) 

 — Californian 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 calyx 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. 1. c. 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 cylindrical-spicate and nearly continuous, conspicuously white-hirsute or 

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



P. Douglasii, Benth. l. 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. Mag. t. 5886 ; Gray, Bot. Calif, i. 597. P. mulliflora, Benth. 1. 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, Douglas, 

 Bolander, &e. 



# * 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. 1.597. — Near San Biego, 

 D. Cleveland. 



§2. Hedeomoides, Gray, I.e. 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. tendipl<3ra. Gray, Proc. Am. Acad. xi. 100, of Guadalupe Island off Lower California, 



has the 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, thlckish ; 

 uppermost, with the rigid narrow bracts and calyx, liirsute-ciliate with strong and white 

 bristly hairs : inflorescence capitate or short-spicate : calyx-lobes slightly unequal, broadly 

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

 the corolla : posterior fllaments as large as the anterior, but tlieir anthers abortive. — 

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

 Bolander. 



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

 diffuse, 3 to 6 inches 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
