behind San Diego; Parry; (a somewhat glabrate form.) Nuttall's original specimens are 
depauperate and not fully developed ; they gave rise to the unfortunate phrase “ heads small,’’ 
in the Flora of North America. But, in fact, they are perhaps the largest 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 Californian collection, No. 313, which presented no mature fruit. Dr. 
Parry's specimen is also a single one, (more swo,) but with well-formed fruit. The only points 
to be 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, are slightly 
incurved, compressed, and not manifestly striate. The compression of the achenia tends to 
confirm the genus as distinct from Cheenactis, although the numerous analogous cases in this 
subtribe warn us to beware of genera resting solely on the absence of pappus. Vide, Plantae

panulato 8-phyllo lanuginoso, squamis erectis discum adequantibus; ligulis 8 roseis ovalibus 
3—4-dentatis ; appendicibus styli fl. disci cono acutissimo superatis; receptaculo conico; acheniis 
hirsutulis; pappi paleis 8 enerviis obtusissimis.—Interior of California, in a dry valley, near 
San Felipe, (between San Diego and the Rio Colorado;) June; Parry. 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-oblong, the alternate ones narrower and more spatulate, entire. 
With the style of true Bahia, but 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. trolliifolia, of which it is probably a true 
congener.
