present it may stand as var. intermedia ; Ido not think it can pos- 
sibly be regarded as a valid species. It has nothing to do with the 
odorata series, though the plants have a certain superficial resem- 
blance to the annuals of southern New Mexico. 
“ Hymenoxys Earlei (Ckll.) 
Picradenia Earlei Cockerell, Bull. Colo. College Museum, 
December I1, 1903. 
Apparently perennial, erect, as tall as H. floribunda, and with 
much the same manner of growth, but less spreading ; leaves 
similar to those of HY. floribunda, but segments inclined to be 
broader; stems reddened at base, without cottony tomentum ; 
heads broader in proportion to their length than in A. floribunda, 
rays orange (clear yellow in 1. floribunda) ; outer bracts yellowish, 
broad and obtuse, stgongly convex, united not over one-third ; 
pappus-scales (viewed by transmitted light in glycerine) ferruginous, 
pointed but not at all aristate; corolla cylindrical, not expanded 
above. The rays are only about 1 mm. broad. The inner bracts 
are much thickened dorsally. (PLATE 21, FIGURE I.)

Other sheets from the same original lot are in the herbaria of the 
National Museum, the California Academy of Sciences, the Mis- 
souri Botanical Garden, and the New Mexico Agricultural Col- 
lege. Those in the last-mentioned herbarium are dwarfed plants, 
like those mentioned as frequently occuring in H. floribunda. 
A rather unsatisfactory specimen, with scanty foliage, is from 
San Luis Park, Colorado, 1877, /. D. Hooker & A. Gray, in herb. 
Calif. Academy of Sciences. It has the pappus-scales longer- 
pointed than in the type, but the manner of growth, foliage, etc., 
are those of 1. Earlei. 
It is not altogether impossible that H. Earlei may be connected 
by intermediates with H. floribunda, but I expect that field-study 
will only emphasize its distinctions.
