THE SESSILE-FLOWERED SPECIES OE PAROSELA IN MEXICO. 



In 11 former paper in tlii.s serios^ the reasons are given for tuking 

 up the name Parosela instead of Dalea, and a nearly completed list 

 is supplied of the iSIexican species with podiceled flowers, Below will 

 be found the remaining species, so far as studied, arranged in the 



order in Avhich 1 liaA e chissifitMl them in my preliminary^ treatment. 

 Further work in this genus may change this arrangement somewhat. 

 There are perhaps still two dozen or even more species in Dalea not 

 included in these lists, but since these are species not yet studied or 

 whose exact status is not known it seems best not to consider them 

 now. These will be reported upon in another paper after more study 

 and further exploration in Mexico. Besides these, a considerable 

 number of new species already indicated, hut not 3'et all described, 

 will be presented at another time- Names wdnch have been previ- 

 ously published under Paroscla ai'(^ given without synonymy,
