Descriptive Flora 



each of the clusters of leafy bracts that form opposite each other 

 at intervals all along the upper parts of the stem and branches. 

 Leaves simple, opposite. Blades sparingly hairy, narrow, sessile, 

 entire or with very few coarse teeth. Corolla 2-lipped, widely 

 gaping, % to 1" long, very hairy in the throat. Upper lip small, 

 concave. Lower lip much larger and longer, broad, flat, 3-lobed, 

 the middle lobe broad and notched. Calyx conspicously hairy 

 on the outside, and bearded so densely within that the throat is 

 closed at maturity. Stamens 2. March to July. On dry lime- 

 stone hills and well drained hillsides. 



Salviastrum seems to take two distinct forms. The second 

 and more common one has the corolla tube longer and narrower, 

 exceeding the calyx tube, and color is violet (not pale blue) with 

 2 parallel white bars that resembles fangs on the lower lip. 

 Leaves are broader, often nearly oblong, and the floral leaves are 

 longer. This may be Salvia engelmannia Gray. 



Monarda dispersa Small. Purple Horsemint. " Aroma 



Rather coarse-stemmed plant with showy purple rosettes of 

 flowers, surrounded by a whorl of purplish, 3-veined, leafy bracts 

 at intervals along the upper portion of the stems. Leaves simple, 

 set in opposite pairs on the stems. Blades linear to narrowly ob- 

 long, 1 to 4%" long, aromatic, closely dotted with minute glands, 

 shallowly saw-toothed. Corolla funnel-form, strongly 2-lipped, 

 wide-mouthed, gaping, lilac to rose purple, covered with minute 

 glands. Upper lip arched. Lower lip larger, spreading, 3-lobed. 

 Calyx with 5 bristle-tipped lobes at the top, and densely bearded 

 in the throat. April to July. Grows in patches along the road, 

 along railroad tracks, and in pastures. A white-flowered form 

 with lower lip dotted with purple, and with pale bracts is quite 

 common. Monarda dispersa differs from the succeeding species 

 by the bristle-tipped calyx lobes and bracts and the larger 

 corolla. 



Monarda lasiodonta (A. Gray) Small. White Horsemint. 



Similar to the purple horsemint but leaves are linear-lanceo-
