24. LEPTANDRA Nutt. Gen. 1:7. 1818. 



Tall stout erect perennial herbs, with verticillate or opposite leaves, and small minutely 

 bracted white or blue flowers, in dense peduncled spike-like racemes, terminal, or in the 

 upper axils. Calyx 4-parted, short. Corolla tubular, or salverform, nearly regular, 4-lobed, 

 the tube cylindric, longer than the lobes. Stamens 2, exserted, inserted low down on the 

 corolla-tube; filaments filiform; anthers obtuse, short. Style about as long as the stamens, 

 stigma minute. Capsule narrowly ovoid, scarcely compressed, not emarginate nor obcordate, 

 4-valved at the apex. Seeds numerous, oval, minutely reticulated. [Greek, slender stamens, 

 referring to the filaments.] 



Two species, the following typical one native of eastern North America, the other of north- 

 eastern Asia.

 commonly i-sided racemes. Calyx 5-parted, the segments imbricated. Corolla declined, 

 somewhat irregular, the tube contracted above the ovary, then rather abruptly expanded, 

 longer than the 4-5-lobed slightly 2-lipped limb; upper lip broadly emarginate or 2-cleft; 

 lower lip 3-lobed, the middle lobe largest, the lateral ones exterior in the bud. Stamens 4, 

 didynamous, ascending, mostly included ; anthers approximate in pairs. Style slender ; stigma 

 2-lobed. Capsule ovoid, septicidally dehiscent. Seeds numerous, rugose. [Latin, digitale,
