MINT FAMILY 647 



calyces hirsute-ciliate or glabrate. Calyx deeply 5-cleft, the two lower teeth longer, the 

 tube mostly IS-nerved, glabrous within. Corolla blue or purple, the tube exserted, tubular- 

 funnelform; upper lip erect, entire, lower spreading, 3-lobed. Stamens 4, all antherifer- 

 ous, or the upper pair sterile, ascending under the upper lip; filaments pubescent. Style 

 slightly exserted, bearded. [Name Greek, meaning bearded and female, in reference to 

 the bearded style.] 



A California genus of about 4 species. Type species, Pogogyne Douglasii Benth. 



All 4 stamens bearing fertile anthers; style densely pubescent below stigma-lobes. 



Floral bracts and calyx-lobes conspicuously hirsute and bristly ciliate. 1. P. Douglasii. 



Floral bracts and calyx-lobes glabrous or nearly so. 2. P. nudiuscula. 



Only the lower pair of stamens bearing fertile anthers, the upper filaments with or without rudimentary anthers 

 sometimes completely suppressed. 



Stems generally prostrate or spreading, slender; corolla 2.5-5 mm. long; nutlets 1 mm. long. 



3. P. scrpylloides. 



Stems erect or essentially so, generally robust; corolla 4-8 mm. long; nutlets 1.7-2.5 mm. Jong. 



4. P. zizyphoroides.

Pogogyne Douglasii subsp. minor J. T. Howell, loc. cit. 



Stems erect, simple or branching below, 5-45 cm. high, glabrous or puberulent. Leaves 

 1-2 cm. long, narrowly oblanceolate to elliptic, mostly obtuse, entire or shallowly and remotely 

 toothed, usually obtuse, attenuate below to a broad petiole ; inflorescence in a dense spike or the 

 lower verticils distinct, 1-3 cm. broad; bracts linear to oblanceolate, mostly pungent at apex, 

 densely conspicuously bristly ciliate on the margins; calyx 8-12 mm. long, the lower teeth 1.5- 

 2.5 times as long as the tube, the upper shorter, ciliate on the margin, the tube glabrous or 

 puberulent ; corolla 1-2 cm. long, lavender or purple, the palate of the lower lip often mottled 

 with pale yellow ; fertile stamens 4, anthers and upper part of filament pubescent ; style a little 

 exceeding corolla, pubescent for 2-6 mm. below the lobes ; nutlets obovoid, brown. 



Low ground, especially in dry beds of winter pools. Upper Sonoran Zone; Lake and Butte Counties, south 

 to Kern and San Luis Obispo Counties, California. Type locality: California. Collected by Douglas. May-July. 



Pogogyne Douglasii subsp. parviflora (Benth.) J. T. Howell, Proc. Calif. Acad. IV. 20:117. 1931. 

 (Pogogyne parviflora Benth. Lab. Gen. & Sp. 414. 1834.) Inflorescence subcapitate; bracts oblanceolate to 

 linear; lower calyx-lobes relatively stouter, only 1-1.5 times the length of tube; corolla 11-15 mm. long; style 

 hairy 4 mm. below stigma-lobes. Low places in the valleys of North Coast Ranges, Mendocino, Lake and Sonoma 

 Counties, California. Type locality: "Hab. in California septentrionali." First collected by Douglas. 



2. Pogogyne nudiuscula A. Gray. San Diego Pogogyne. Fig. 4427. 



Pogogyne nudiuscula A. Gray, Bot. Calif. 1: 597. 1876. 



Stems 1-3 dm. high, simple or branching from the base, erect or somewhat spreading. Leaves 

 broadly to narrowly oblanceolate, 1-2 cm. long, narrowed to a petiole about as long as the blade, 

 obtuse or acute, entire or nearly so, glabrous ; inflorescence a short subcapitate spike usually with 

 1 to several rather distinct verticils below ; bracts oblanceolate to linear-oblanceolate, glabrous 

 or sparsely ciliate on the margins ; calyx-tube 3-4 mm. long, glabrous or very sparsely pubescent, 

 strongly nerved ; lower calyx-lobes 3-5 mm. long, margins of the lobes smooth or thinly ciliate ; 

 corolla 1 1-14 mm. long, lavender, sparsely pubescent outside ; all 4 stamens fertile, the lower 

 pair 5-6 mm. long, glabrous ; upper pair 2-3 mm. long, pubescent ; style pubescent, 1-4 mm. 

 below the stigma-lobes. 



Dry bottoms of winter pools. Lower Sonoran Zone; mesas in the vicinity of San Diego, California. Type 

 locality: San Diego. May-June. 



Pogogyne Abramsii J. T. Howell, Proc. CaliL Acad. IV. 20: 119. 1931. Similar to P. nudiuscula A. Gray, 

 floral bracts and calyx-lobes conspicuously hirsute and bristly ciliate. Mr. Howell's field notes on his specimen 

 (6636) read in part as follows: "upper lip of limb cucuUate, the lobes of the lower lip reflexed; limb and 

 throat rich rosy-purple, tube white; middle lobe of lower lip with central yellow area spotted with deep purple." 

 Dried bottoms of winter rain pools, on mesas north of San Diego, California. Type locality: mesa five to six 

 miles north of San Diego. April-June. 



This species is a close relative of P. nudiuscula and possibly not specifically distinct. However, although 

 both species grow in the same general region no one has reported them as growing together and no intermediate 

 forms have been noted.

Hedeomoides serpylloides Briq. in Engler & Prantl, Nat. Pflanzenf. 43«: 295. 1897. 



Stems slender, diffusely spreading from the base or rarely simple and erect in diminutive 

 plants, 3-25 cm. long, retrorsely puberulent. Leaves oblanceolate to oblong-obovate, narrowed 

 to a petiole about equaling the blade, 5-10 mm. long, entire, glabrate or those subtending the 

 verticils short-ciliate toward the base ; inflorescence usually of several distinct lower verticils 

 and two or more upper ones crowded into a short subcapitate spike ; floral bracts equaling or 

 exceeding the calyx, spatulate to linear-oblanceolate, somewhat ciliate on the margins ; calyx- 

 tube 1-3.5 mm. long, thinly pubescent in the nerves, lower teeth 2-4 mm. long, the upper 

 1.5-3 mm., ciliate on the margins; corolla 3-5 mm. long, lavender; lower pair of stamens fertile,
