224 Mr. D. Don's Descriptions of new Genera and Species 



bilabiati, lactei ; labio exteriore petaloideo, orbiculato, ob- 

 tusfe tridenticulato, 4-nervio, patulo ; interiore bipartite : 

 segmentis lanceolato-attenuatis, apice obtusulis, revolutis. 

 Anthera appendicula ovato-lanceolat^, acut^, membrana- 

 ced terminatae, basi bisetae : setis linearibus, acutis, com- 

 planatis, simplicibus, ipsA^ anther^ ferfe dupl6 brevioribus. 

 Stigma bipartitum : segmentis recurvis, apice truncatis, 

 minute papillosis. Achenia trigona, undique villosissima. 

 Pappi radiis 3, paleaceis, linearibus, canaliculatis, caducis : 

 apice recur vato, ciliato, niveo. 



Ihis curious genus agrees with Proustia, before described, m 

 the definite number of its florets, in its hairy receptacle, and 

 in its imbricate involucruin; but I have placed it here prin- 

 cipally on account of the structure of its pappus, although the 

 difference of this organ is moi*e apparent than real: for the 

 palese, which crown the fruit of this genus, are evidently formed 

 by the confluence of innumerable fibres, whose extremities even 

 in this instance are free. ii.,oM4«i»-v>i>^5V w ;
