 21. MONARDELLA^ 



Perennial herbs, usually forming a low bush with several or nu- 

 merous ascending branches; leaves elliptic or oblong, entire; flowers in 

 terminal subglobose heads, these subtended by a few bracts similar 

 to the leaves but usually thinner and colored ; calyx tubular, the teeth 

 narrowly deltoid, erect, subequal; corolla white and usually purple- 

 punctate, or rose-colored, the tube somewhat exserted from the calyx, 

 the lobes oblong-linear, subequal; stamens 4, exserted; nutlets oblong, 

 smooth. 



The genus Monardella is inexplicable in terms of a conventional 

 system. The forms of each isolated region have a more or less 

 characteristic aspect, difficult or impossible to define, and form a 

 continuous spectrum of variation with the forms of other regions. 

 The genus is predominantly Californian. M. lanceolata Gray, an 

 annual species, may occur in northern Arizona. 



Key to the species 

 1. Pubescence curled downward; bracts ovate to rotund, usually cupped. 



1. M. ODORATISSIMA. 



1. Pubescence spreading; bracts narrowly ovate, spreading. _ 2. M. arizonica.

Kaibab Plateau, San Francisco Peaks (Coconino County), Hualpai 

 Mountain (Mohave County), 5,700 to 10,000 feet, mostly in conif- 

 erous forests. Montana to Washington, south to New Mexico, 

 northern Arizona, and California. 



2. Monardella arizonica Epling, Wash. Acad. Sci. Jour. 29: 489. 



1939. 



Black Mountains (Mohave County), Sierra Estrella (Maricopa 

 County), Silver Bell and Quijotoa Mountains (Pima County), Kofa 

 Mountains (Yuma County), 2,200 to 4,000 feet, rocky ledges in 

 canyons, spring, type from the Sierra Estrella {Epling). Known only 

 from Arizona. 



The form from the Black Mountains is perhaps not conspecific. 



22. LYCOPUS. Bugleweed 



Plant perennial, pubescent or glabrate; stems erect, up to 1 m. 

 high; leaves sessile or nearly so, oblong-lanceolate, sharply serrate; 

 flowers small, in dense sessile axillary clusters; calyx campanulate, 

 nearly equaling the corolla, regular or nearly so, with 4 or 5 subulate- 

 aristate teeth; corolla whitish, nearly equally 4-cleft; perfect stamens 

 2, the others rudimentary; nutlets turbinate, trigonous. 



1. Lycopus lucidus Turcz. ex Benth. in DC, Prodr. 12: 178. 1848. 



Only 1 collection is known from Arizona, without definite locality 

 (Palmer in 1869). Minnesota to British Columbia, south to Kansas, 

 Arizona, and California; northern Asia. 



Palmer's specimen has continuous corklike wings on the angles 

 and summit of the nutlet, and the leaves are sessile and merely serrate.
