658 MENTHACEAE 



puberulent. Leaves lanceolate to linear-oblong, 1-3 cm. long, strigose, narrowed at base to a 

 short petiole ; heads 1-1.5 cm. broad ; bracts ovate-lanceolate, acuminate, 1-1.5 cm. long, fenestra- 

 like, the midvein prominent, lateral veins ascending and anastomosing to form a prominent mar- 

 ginal vein, the intervenous spaces membranous and translucent, the veins roughly puberulent and 

 purple ; calyx rather thinly hirsute, the teeth triangular-lanceolate, cuspitate ; corolla deep reddish 

 purple, tube little-exserted, lobes especially those of the upper lip ending in a cup-shaped gland.

 County to San Benito and southeastern Monterey Counties, California. Type locality: "California." Collected 

 by Douglas. June-July. 



Monardella Douglasii var. venosa (Torr.) Jepson, Fl. Calif. 3: 443. 1943. {Monardella candicans var. 

 venosa Torr. Pacif. R. Rep. 4: 123. 1857; M. Douglasii var. Parryi Jepson, Man. Fl. PI. Calif. 884. 1925.)

 broad, hirsute-ciliate on the margins. East side of the Sacramento Valley in Butte and Sutter Counties, Cali- 

 fornia. Type locality: "Plains of the Feather River, near Marysville." Apparently a rare species, seldom 

 collected. In addition to the type which was collected by Bigelow in 1854, the only other collections known to

24. PYCNANTHEMUM Michx. Fl. Bor. Amer. 2:7. 1803. 



Perennial aromatic herbs with mostly branching stems, glabrous or pubescent foliage 

 and small white or purple-dotted flowers in terminal or sometimes also axillary capitate 

 glomerules or cymose clusters. Calyx ovoid to cylindric, 10-13-nerved, equally or slightly 

 unequally 5-toothed. Corolla bilabiate, the upper lip emarginate or entire, the lower 

 3-cleft, its lobes obtuse. Stamens 4, didynamous, nearly equal or the lower pair a little 

 longer; anther-sacs parallel. Ovary deeply 4-parted; style slender. Nutlets smooth, 

 pubescent or roughened. [Name Greek, meaning dense and flower, in reference to the 

 glomerate inflorescence.] 



A genus of about 17 species, natives of North America. Type species, Clinopodium incanum L. Koellia 

 (Moench, Meth. 407. 1794.) is the older name, but Pycnanthemum has been conserved by the International Botan- 

 ical Congress.
