13. MONARDATL. Horsemint. 
Annual or usually perennial herbs, 30 to 60 cm. high, with petioled leaves, the 
flowers in crowded verticillate headlike clusters, these forming either terminal heads 
or a series of clusters in the axils of the upper leaves and surrounded by conspicuous, 
often colored bracts; calyx tubular, 15-ribbed, 5-toothed, the teeth about equal; 
corolla flesh-colored, rose, or purplish, 2-lipped, the upper lip arched, the lower 3- 
lobed; anther-bearing stamens 2, 2 rudimentary filaments present or wanting; nutlets 
smooth. 
KEY TO THE SPECIES. 
Flower clusters terminal and solitary; flowers rose purple. 
Stems and petioles villous-hirsute, the former especially so 
below the nodes..............-...------------------- 1. M. comata. 
Stems and petioles finely strigose or puberulent. 
Plants pale green; leaves finely puberulent, velvety to 
the touch, especially beneath..................... 2. M. menthaefolia. 
Plants bright green; leaves glabrous, in the dried speci- 
mens feeling papery to the touch................. 3. M. stricta. 
Flowers in several verticillate glomerules in the axils of the up- 
per leaves, mostly pale. « 
Calyx lobes triangular, acute, about as long as the width of 
the tube (long-ciliate); bracts conspicuously velvety, 
whitish or rose purple above. ...... ne rn 4. M. lasiodonta. 
Calyx lobes narrowly subulate-aristate, several times longer 
than the width of the tube; bracts mostly greenish, 
not conspicuously velvety. 
Bracts lanceolate, tapering into the aristate apex, green; 
calyx teeth, petioles, and bases of leaves sparingly 
or not at all ciliate; plants stout................- 5. M. tenuiaristata. 
Bracts ovate to oblong, abruptly aristate, sometimes 
purplish; calyx teeth densely long villous hirsute, 
the petioles and bases of the leaves sparingly so; 
plants rather slender................-.----------- 6. M. pectinata.

The distinctions between this and the next are so slight that it is doubtful whether 
they should be kept separate, but the various species of this group are all so closely 
related that they are separated with difficulty, and then only with large series of 
specimens.
