Monarddla. LABIAT.E. 593 



Dry and open ground ; common nearly throughout the State to the southern boundary and tlie 

 frontiers of Nevada. The var. glabellum is a green and glabrate state, hardly needing a distinc- 

 tive name. 



5. MONARDELLA, Benth. 



Calyx tubular, narrow or elongated, 10 - 13-nerved, 5-tootlied ; tlie teetli short, 



straight, and nearly equal ; the throat naked within. Corolla with tlie tube either 



slightly or manifestly longer than the calyx, glabrous within ; the 2-cleft uj)per lip 



and the lobes of the 3-parted lower one all flat and linear or oblong. Stamens 



4, exserted, either strongly or moderately unequal : anther-cells often divergent or 



divaricate. — Annual or perennial sweet-odorous herbs (all Californian, one or two 



extending to Oregon) ; with the aspect, inflorescence and calyx of Monarda, and the 



corolla rather of Fi/cnaiithemum, but mostly on a larger scale : the flowers compacted 



in terminal heads involucrate with bracts, rose-color, purple, or white. Leaves 



entire or obscurely toothed. — Lab. 331, & DC. Prodr. xii. 190. 



§ 1. Flowe7-s comiKtrativeh/ few and loose in the head, large: corolla mostly with long- 

 exserted tube : anther-cells oval-oblong, divaricate. 



L M. macrantha, Gray. Perennial, tufted, a span high from creeping rather 

 woody rootstocks, puberulent or pubescent : leaves thickish, ovate, obtuse (6 to 10 

 lines long), glabrate, slender-petioled : bracts of the 10- 20-flowered head ovate or 

 oblong, obtuse, thin-membranaceous or somewhat scarious, sometimes whitish or 

 purplish-tinged, externally like the calyx villous-pubescent : teeth of the latter lan- 

 ceolate, merely acute : corolla about an inch and a half long, glabrous, orange-red ; 

 its tube fully twice the length of the calyx ; the lobes lanceolate. — Proc. Am. 

 Acad. xi. 100. 



Cuiamaca Mountains and near Julian City, northeast of San Diego, Cleveland, Palmer. Calyx 

 three fourths or in fruit even a full inch long. Corolla often nearly 2 inches long, apparently 

 bright orange-colored with the limb scarlet, the tube gradually enlarging upward. 



2. M. nana, Gray, 1. c. Resembles the preceding, with somewhat hirsute pu- 

 bescence : fltnvers smaller : corolla not twice the length of the calyx, white or 

 tinged with rose-color ; the slender tube pubescent : bracts whitish and rose-color. 



Mountains behind San Diego, CJcvdand. Specimens hardly sufficient. Calyx bareh' two 

 thirds of an inch long : tube ol" the pale corolla sometimes hardly exceeding its lanceolate teeth, 

 sometimes 2 lines longer. 



§ 2. Flowers numerous and densely capitate : calyx from a, fourth to a third of an 

 inch long : anther-cells shorter and less divaricate. 



* Perennial, in tufts from a procumbent and almost woody base, or from somewhat 

 creeping slender rootstocks: corolla from flesh-color to jyuvple, the tube little if at all 

 exceeding the calyx. 



3. M. villosa, Benth. Soft-pubescent or villous, a foot or two high : leaves 

 ovate, often with a few obtuse teeth, veiny (G to 10 lines long), petioled : bracts 

 ovate, foliaceous, pinnately veined. — Lab. 332, & Bot. Sulph. 42, t. 21. — Varying 

 greatly, especially in the pubescence. 



Var. leptosiphon, Torr. : a less pubescent form, with thinner and almost entire 

 leaves, on slender petioles, and slender more exserted tube to the corolla. — Bot. 

 Mex. Bound. 1 29. 



Var. glabella, Gray : a form with nearly oblong leaves, sometimes almost ses- 

 sile, varying from 5 to 18 lines in length ; the pubescence very close and minute. — 

 Proc. Am. Acad, vii. 386. M. Sheltoni, Torr. in Durand, PI. Pratten. 



Dry and mostly wooded grounds, common through the State ; the more villons foriii, which 

 suggested the specific name, chiefly southward.
