behind San Diego; Parry; (a somewhat glabrate form.) NuttaU's orighial specimens are 

 depauperate and not fully developed ; they gave rise to the unfortunate plirase ^^ heads small^'* 

 in the Flora of North America. But, in fact, they are perhajis the hirgest of the genus. The 

 conspicuous pappus at length projects beyond the villosity of the achenium.

 Cordilleras east of San Diego, California, June ; Parry. This rare plant was known only from 

 a specimen in Coulter's Califoruian collection, No. 813, which presented no mature fruit. Dr, 

 Parry's specimen is also a single one, (more mo^) hut with well-formed fruit. The only points 

 to he added to the original account of the plant are that the viscid-glandular leaves are scarcely, 

 if at all, hoary ; the corollas appear as if they were flesh-color rather than pale yellow, and 

 the marginal ones are hardly ampliate ; the mature achenia, all fertile and similar, arc slightly 

 incurved, compressed, and not manifestly striate. The compression of the achenia tends to 

 confirm the genus as distinct from Ch^Dnactis, although the numerous analogous cases in this 

 suhtrihe warn us to heware of genera resting solely on the ahsence of pappus. Vide^ Plantae

) 



Plant 4 inches high ; the 



leaves half on inch long. Peduncles from half an inch to an inch in length. Involucre 3 lines 

 long. Disk-flowers 14-20, yellow. Ligules oval, deeply notched or 3-4-toothed at the 

 apex. Pappus about one-quarter the length of the prismatic achenium; the paleae of equal 

 length, four of them obovate-ohlong, the alternate ones narrower and more spatulate, entire. 

 With the style of true Bahia, hut the appendages tipped with a longer and sharper cone this 

 little plant has the involucre of the section Eriophyllum, and a still more elevated (even 

 conical) receptacle ; and so tends to combine the two. In the rays, which are said to be pale 

 purple and white, it accords with the obscure B, troUiifolia, of which it is probably a true 

 congener.
