and obtusely 5-lobed. The capsule 2-celled, opening 

 above. The G. purpurea, flowering from August to 

 October, is not unl'requent in moist sandy soils, and 

 marshes, near waters. It is much branched, bearing 

 long, scabrous, linear, acute leaves ; and large, purple, 

 subsessile flowers; with the divisions of the calyx sub- 

 ulate. Another species in drier places, in woods, the 

 G. tenuifolia, is very similar, but lower growing, and 

 with peduncles which are longer than the purple flow- 

 ers. The G. flava of the second section, unlike the 

 preceding, is perennial ; having nearly a simple stem, 

 subsessile, lanceolate, pubescent leaves, either entire 

 na toothed, the lower ones deeply so, with subsessile, 

 large, yellow flowers like those of the Foxglove. In 

 the corolla of several of these species there is often 

 the rudiments of a 5th stamen. 



In wet places and ditches, about the month of Au- 

 gust, you will not unfrequently meet with the Mhnulus 

 ringens, with blue, ringent, almost personate flowers ; 

 having the palate of the lower lip prominent, and the 

 upper lip reflected at the sides. The calyx is also 

 angular, with the summit 5-toothed ; the stigma thick, 

 and bifid ; the capsule 2-celled, the seeds numerous 

 and minute. This species is erect and smooth, with 

 sessile, lanceolate, acuminate leaves, and axillary pe- 

 duncles longer than the flowers. The M. alatus is 

 very similar, but has quadrangularly margined stems, 

 peduncles shorter than the flowers, and petiolated, 

 broader leaves. 



In Pcntstemon, a peculiar genus of America, abound- 

 ing in the western wilds and territories, there is a 5- 

 leaved calyx (as in Foxglove) ; a bilabiate, ventri- 

 cose corolla ; a ffth sterile filament longer than the 

 rest, and bearded on its upper side ; and hence the 

 name of PentaHnnon. The capsule is ovate, 2-celled, 

 2-valved, containing many angular seeds. There arc
