the banks of the lower Ohio, and Missouri ri- 

 vers, a small plant extending 3 to 6 inches with 

 many short branches, leaves 3 lines long. 



760. DIONEA SESSILIFLORA Raf. atl. J. 78. 

 Petiols winged oblong or cuneate narrow, acute 

 at both ends, leaves bilobe ; flowers sessile agre- 

 gate 3 to 5, bracts lanceolate. The beautiful 

 G. Dionea is no longer monotype but has devia- 

 ted sp. D. muscipula the type is quite distinct 

 from this by petiols broadly obcordate, flowers 

 corymbose. Seen alive in our gardens as well 

 as a variety Uniflora, smaller uniflore, with 

 broader shorter leaves, petiols oblong acute 

 winged. Both native of Carolina, flowers white 

 estival, leaves irritable in all. This G. is the 

 type of a Nat. Family DIONIDIA different from 

 ALSINIDIA by single style.

761. PULMONARIA ELLiPTicA R. leaves ellip- 

 tic acute at both ends, the radical on very long 

 petiols, upper ovate ; flowers axillary peduncu- 

 late nodding, calix with short segments lanceo- 

 late acute. In the Apalachian Mts. of Virginia 

 and Carolina, stem smooth branched bipedal, 

 flowers blue and small. 



762. LITHOSPERIHUM CRACILE Raf. annual, 

 silky villose, stem slender erect virgate naked 

 below, leaves petiolate linear acute adpressed, 

 flowers terminal subsessile, tube of corolla 

 longer than calix, segments of corolla oblong 

 obtuse. A very striking sp. sent me from Ala- 

 bama and found on Red River Arkanzas and 

 Texas by Nuttal in Collins herb, where noted 

 as perhaps a N. G. but I see no difference, un- 

 less the fruit be different, the corolla is realy 

 funnel .shape, but the lobes deeper or longer. 

 Stem semipedal nearly simple, leaves uncial
