Galatlienium macrophyllum. Sonchus macrophyllus, Willd. Mulgedium ma- 

 cr(yphjllum, Decand., Vol. VII., p. 248. 



Galatlienium multiflorum. Mulgedium miLltiJlorum, Decand.. Vol. VII., p. 

 249. Perhaps too nearly allied to the following. 



Galathe?iium Floridanum. Sonchus Floridanus, Linn. Mulgedium Flori- 

 danum, Decand., ib., p. 249. Achenium scarcely striated. 



Galatlienium * salicifolium; il, very smooth; stem simple and terete; leaves 

 entire, lanceolate or linear-lanceolate, much acuminate, sessile, lower ones re- 

 pandly dentate; panicle contracted, racemose, bracteate; achenium elliptic, 

 acute, with a single nerve on either side, the stipe nearly the length of the 

 fruit. 



Hab. In West Florida. (Mr. Ware.) Bethlehem, Pennsylvania and Salem, North Carolina. 

 (Herb. Schweinitz.) The flower appears to have been pale blue or white. Leaves three to four 

 inches long, by half an inch wide, entire, or now and then Avith a slight denticulation, but nothing 

 down to the root like dentation or division of any kind, (in the three perfect specimens before me.) 

 Uppermost leaves diminishing to bractes with long filiform acuminations. Flowers crowded, on 

 short bracteolate pedicels in the Florida specimen, the flowers racemose, and rather distant. 



Galatlienium graminifolium. Lactuca graminifolia, Mich., Flor. Bor. Am., 

 Vol. IL, p. 85. Stem leaves entire, sagittate at base. Achenium elliptic-lan- 

 ceolate, dark brown, with one striature on a side only, the stipe nearly as long 

 as the fruit. Panicle divaricate, naked and dichotomous. Radical and lower 

 stem leaves more or less runcinate.
