1 -series. Herbaceous : stems naked at the apex corymbose : 

 involucrum ovate 1 -series, with 3-5-calyculate scales ; recep- 

 tacle naked. [This genus, so far as I can learn from written 

 characters, is not distinct from Lactuca, L. saliva being 

 apparently about as justly referable to the one as the other.] 



97. Brachyramphus, (D. C. 7-176). Capitula 10-15- 

 flowered : achaenia oblong muricate, suddenly attenuated into 

 a short beak, neither angled nor costate : pappus many series. 

 Herbaceous : capitula racemosely spicate : involucrum oblong 

 imbricated, the scales scariose on the margin : receptacle 

 naked. 



98. Microrhynchus, (Less. D. C. 7-180). Capitula se- 

 veral flowered : achaenia 4, rarely 5- angled, subrostrate at ma- 

 turity ; beak wanting in the ovary : costae thick subbrugose : 

 pappus pilose. Herbaceous perennials : involucrum cylin- 

 drical calyculate, imbricate at the base : receptacle naked : 

 flowers yellow. 



99. Sonchus, (Cass. D. C. 7-184). Capitula many flower- 

 ed : achaenia wingless, compressed, erostrate, longitudinally 

 costulate ; costulae often transversely tuberculato-muricato : 

 pappus soft, most slenderly filiform. Herbaceous polymor- 

 phous plants : involucrum imbricated : receptacle naked : 

 flowers yellow. 



100. Youngia, (Cass. D. C. 7-192). Capitula about 12- 

 flowered : corolla pilose at the apex of the tube : achaenia 

 oblong, compressed, subtrigonous, striated, beakless, at- 

 tenuated at both ends : pappus pilose, scarcely denticulate. 

 Herbaceous plants : inferior leaves lyrate or pinnatifid : capitu- 

 la paniculate : involucrum cylindrical 8-leaved, with about 

 5-calyculate accessory scales : receptacle naked. [D. C. con-
