TRIBE 6. AJUGE'AE. 



Corolla, with the upper Up sometimes very short, sometimes deeply cleft, with the 

 lobes depending, rarely erect and arched ; lower lip elongated ; stamens mostly 

 didynamous, and much exserted; nutlets reticulately rugose, obliquely affixed, and

SOS. TRICHOSTEW A, L. 



[Or. Thrix, trickos, hair, and Sterna, stamen ; from its long hair-like stamens.] 

 Calyx depressed-campanulate, oblique, resupinate, unequally 5- 

 cleft; the 3 tipper teeth (becoming the lower ones, by the twisting of 

 the peduncle) elongated, and partly united ; the lower (finally upper) 

 teeth very short. Corolla 5-lobed ; lobes oblong, declined. Stamens 

 much exserted, declined and then curved upward ; anther-cells 

 divergent, finally confluent. Annuals: leaves entire; flowers axil- 

 lary, the inflorescence finally elongated into brachiate leafy racemes. 



1. T. dicliotomuni, L. Stem bushy; leaves lance-oblong, or 

 rhombic-lanceolate, rather obtuse, petiolate; flowers solitary, in 

 the axils of leaf-like bracts. 

 DICHOTOMOUS TRICHOSTEMA. Bastard Pennyroyal. Blue Curls. 



Stem 6 to 12 inches high, brachiately branched, clothed with a short cinereous 

 ronghish pubescence. Leaves 1 to near 2 inches long, tapering at base to a petiole 

 % to % an inch in length. Flowers on peduncles % to % an inch long, the ter- 

 minal ones di- or tri-chotomous ; bracts lanceolate, shorter than the peduncles; 

 corolla bright blue, rarely purplish.

 equal, oblong and declined, the lower lobe largest, mostly concave. 

 Stamens exserted from the fissure on the upper side of the corolla ; 

 anther-cells confluent. Cymules few-flowered, in a terminal rather 

 crowded greyish-green spike.

Perennial. Stem 1 to 2 feet high, simple, or sparingly branched, square with the 

 sides concave and the angles obtuse, retrorsely pubescent. Leaves 3 to 5 inches 

 long; petioles % to % of an inch in length. Cymules 2- or 3-flowered. in a simple 

 tpteate raceme 2 to 6 inches in length (often an opposite pair of such racemes from 

 the axils of the first leaves beneath) ; bracts about as long as the calyx ; coroOa 

 pale purple. 

 Bab. Moist, shaded grounds : frequent Fl. July. Fr. Aug. 



Obs. An intelligent practical farmer, a few years since, brought 

 to me specimens of this plant, as one which he had found to be a 

 very pernicious weed, and difficult to get rid of. Whether others
