cd, lower leaves sessile cuneate remotely obtuse 

 serrate, not trinervate, upper leaves decurrent 

 lanceolate acute subcrenate, rays grooved ? disk 

 globose discolor — another sp. akin to H.canal- 

 iculatum, but not smooth nor properly serrate, 

 stem bipedal quite dichotomous above, lower 

 leaves 3 inches long, upper uncial, disk redish 

 as in last, found in West Kentucky, 



946. Helenium traxiltihi li. nearly smooth, 

 stem angular striate hardly winged, leaves sub- 

 decurrent lanceolate elongate, both ends acu- 

 minate, margin entire very rough ; flowers co- 

 rymbose, rays flat reflexed, disk globose conco- 

 lor — found in Indiana and Illinois, pedal, leaves 

 large 2 or 3 inches long pale beneath, flowers 

 few small. — H. autumnale nearest to this has 

 serrate smooth leaves, and several varieties, an- 

 gustifolium^ latifolium, lemgatum^hrevifolium 

 longifoliuniy elatiim, patirifJorutn &^c,

This family also called Cichoracea and ^etni- 

 flosculose, has been stated to be very deficient 

 in North America ; but it is a mistake, 5 Genera 

 alone Lactuca, Eimoxis, Hieracitim, Nar- 

 halia and Krigia, include nearly 100 species; 

 being as numerous as the Asters, they have 

 been equaly involved in obscurity by blending 

 or overlooking sp. which require careful mono- 

 graphs, such as I have undertaken ; but must 

 delay at present and only give a few striking 

 novelties, as I wish to confine this flora to 1000 

 articles at present. This continent is the cen- 

 tral seat of Lactuca as it is of Vitis and Quer- 

 cus, possessing 30 or 40 species of each. The 

 Lactuca elongala of our blind botanists con- 

 tained 12 or 15 sp.with leaves smooth or rough, 

 entire or pinnatifid^ runcinate, sagittate, den-
