(t) Cannabis saliva. The hemp has long been extensively 

 cultivated in the u Elkhorn country 1 ' around Lexington, and 



the exuberant fertility of the soil of this district is admirably 

 adapted to its culture. Owing to these cii I :es it has 



become partially naturalized, and we have met with it in se- 

 cluded situations, miles distant from any scene of cultivation. 



(1) Convolvulus micranthus. For a description of this spe- 

 cies, see "A synopsis of the Flora of the Western States. By 

 John L. Riddel!, A. NL" (Cincinnati. O. 1835.) p. 70. "Close- 

 ly allied to C. lacunosus. Sprengt perhaps only a variety of it." 



(2) Eupatoreum *Torrcyanum. Leaves tern ate and oppo- 

 site, sub-sessile, narrow-lanceolate, coarsely serrate, three 

 nerved, punctate beneath, glabrous above. 



Description: Stem solid, erect, striate, purplish, slightly 

 pubescent below, becoming more so above, about two feet 

 high; lower leaves by threes, narrow lanceolate on short pe- 

 tioles or mostly subsessile, with a few coarse serratures, and. 

 scabrous on the margin, three nerved and thickly sprinkled be- 

 neath with glandular dots; upper leaves opposite, or by threes, 

 narrower and less serrate. At the axil of each leaf is a small 

 branch with numerous small narrow entire leaves, all glandu-

 Corymb nearly iastigiate. Involucrum 5-flowercd, 8-10 leav-

 pappus slighty scarious; pistil deeply cleft, the divisions re- 

 volute. 



Found on dry sandstone knobs in the'barrens of Kentucky, 

 near the Mammoth Cave; flowering September 20th. 



This species has some agreements with E, parvijlorum, and 

 perhaps still more with £?• am<rnum* but seems in some parti- 

 culars to difFer from both; from the last especially in not hav- 

 ing the "coloured" leaves of the involucrum, nor the "purple 

 or flesh-coloured flowers" — ours arc a pure white. The name 

 trifoliatuiH) or tcrni folium* would be peculiarly appropriate for
