Gray, Pl. Lindh. 2. p. 218. On the Rio 



Texas. I find from De Candolle's herbarium that this is indeed his Cla\ 

 ttata ; but the leaves are so little toothed, and often entire, that I have pre 

 ferred a later specific name while referring the plant to another genus. The pap 

 pus affords no available distinction between Brickellia and Clavigera, and the latte; 



* Tho species have to be arranged imder a considerable number of sections, somewhat as follows; 

 Pappus coroniformis, vel in disco vel in radio, et SEepius 1 - 4-aristatis : 



Aristis sursumscabris v. nullis. (P. angustifolia, filipes, uniaristata, et sp. nov. Am. Merid.) Pectidopsis. 



Aristis corneis retrorsum hispidis. (P. Coulteri, multiseta.) 

 Pappus uniformis, ex aristis paucis corneis lcevissimis, 

 Pappus uniserialis, e paleis vel aristis basi paleaceo-dilatatis paucis- 

 Pappus biserialis paleaceus, in radio nunc diniidiato-ariculsGformis, nunc nullus* 

 Pappus setosus, 1 - 2-seriaIis, setis capillaribus basi vix aut ne vix dilatatis, in radio nunc
