82 LABIATiE. Trichostema. 



Annual. Stem 8-12 inhces or more in height, very obtusely 4-angled, often purplish, 

 paniculately much branched. Leaves about an inch long and 3-5 lines wide. Pedicels in 

 the axils of small bract-like leaves, 2-3 hnes long, one-flowered, twisting about the time of 

 the opening of the flower, which thus becomes inverted, 5-nerved : three of the teeth of the 

 calyx united except towards the summit, acute but scarcely mucronate ; the other two much 

 shorter, ovate. Corolla bright blue, or sometimes pale. Stamens half an inch or ,more in 

 length, beautifully curved. Achenia large, conspicuously reticulated and pitted. Style equally 

 2-cleft at the summit. 



Sandy fields ; common along the Hudson and on Long Island, but somewhat rare in the 

 northern and western counties. July - September. The plant has a rather agreeable balsamic 

 scent.

[ So named from Teucer, a prince of Troy ; because he is said to have first used the plant medicinally.] 



Calyx tubular-campanulate, almost equally 5-toothed, or somewhat 2-lipped and the upper 

 tooth broader. Corolla with the tube short ; the four upper lobes nearly equal, oblong and 

 declined, or very short and nearly erect ; the lowest lobe largest, oblong, declined. Stamens 

 exserted from a cleft between the two upper lobes of the corolla : cells of the anther con- 

 fluent. Achenia rugose. — Herbs or shrubby plants of various inflorescence and habit.

Perennial. Stem about two feet high, mostly simple, 4-angled. Leaves 3-4 inches long, 

 varying from nearly ovate to oblong-lanceolate, acute or acuminate, serrate, pale green above, 

 soft and canescent underneath ; the petioles 2-4 lines long. Spikes solitary, or sometimes 

 with two or more smaller ones at its base, 3-6 inches long ; the flowers often imperfectly 

 whorled, on short pedicels. Calyx downy, sometimes purplish ; the uppermost tooth rather 

 acute ; lateral ones obtuse ; the two lower acuminate. Corolla pale purple ; the upper lip 

 apparently wanting, owing to a deep cleft between the two lobes : middle lobe of the lower 

 lip remote from the others, and much larger, oblong and concave. Stamens ascending, 

 curved, shorter than the corolla. Style equally 2-cleft at the extremity. Achenes obovoid 

 and somewhat 3-sided, reticulated. 



Low and rather shady grounds ; frequent. July.
