vent and subulated semiovate segments, the 2 upper ones 

 somewhat \urg;er, and directed from the tube of the corol- 

 la. Corolla about an inch lone:, yellowish-white, oi'ten 

 marcescent, not arising from tlie centre of the calix; 

 tube widely inflated or rather funnelform and atteru- 

 ated downwards, at the orifice more than double tiie 

 breadth of the calix; upper lip entire, arounded and dis- 

 tinctly arched; lov\ er lip 3-lobed, all tiic lobes entire and 

 obtuse, the lateral ones oblong and somewhat shorter, 

 central lobe rounded, elegantly striated longitudinally 

 with about 8 purple lines. Stamina converging beneath 

 the upper lip; filaments intricately tomentose on the inner 

 side, anthers corneous, 2-ccIled, yellowish-white with 

 acute blackish sKiping points, the shorter pair perfect and 

 unconnected, tlie longer pair firmly cohering by the mar- 

 gins of their upper cells which are barren or destitute of 

 pollen, the lower cells only being perfect, so that the an- 

 thers are attached without appearing cruciate. Seeds 

 smooth, pale, depressed triquetrous, rarely more tiian 2 

 becoming ripe. — Flowering lime about June. Hab. On 

 the shady banks of the Ohio; in rocky situations near Cin-

Species. 1. S. JiyssopiJoUa. 2. aspera. Stem nearly 

 smooth, angles only somewhat retrorsely aculeate, leaves 

 oblong-lanceolate, acuminate, serrate, shortly petiolate 

 and very smooth; verticills about 6.flowered, calix diva- 

 ricate, spinescent. 3. hispida. The whole plant hispidly 

 pilose; leaves shortly petiolate, cvate-oblong, acuminate, 

 angularly serrate; verticills about 8-flowered, calix subu- 

 lately divaricated. — Nearly allied to the preceding though 

 sufficiently distinct, but scarcely more than a variety of 

 the following? 4. *sylvatica. Verticills 6-flowered; leaves 

 cordate-ovate, petiolate. Mab. On the banks of the Ohio, 

 not uncommon, on the skirts of thickets, giving out the
