OBSERVATIONS ON THE COMPOSIT2. ll 
Professors Eaton and Gray, I fail to distinguish from this 
the EH. resinosa of Nuttall. The species is of the western 
part of the Great Basin, and is seldom collected. According 
to Nuttall the rays are not always well developed as ligules, 
and are ochroleucous rather than yellow, this last a point of 
affinity, as far as it has value, with the West Indian species. 
7. (C. laricifolia. Aplopappus laricifolius, Gray, Pl. 
Wright. ii. 80 (1852). Aster laricifolius, O. Ktze. 1. ¢. 318. 
Plant of the southwestern interior, inhabiting rocky hills and 
low mountains; ligules both well developed and rather 
numerous. 
8. C. euneata. Aplopappus cuneatus, Gray, Proc. Am. 
Acad. viii. 635 (1873). Aster cuneatus, O. Ktze. 1. ¢. 317. 
Middle and southern Sierra Nevada of Callfornia. Heads 
radiate. 
Var. spathulata. Bigelovia spathulata, Gray, Proc. 
Am. Acad. xi. 74 (1876); B. rupestris, Greene, Bot. 
Gaz. vi. 183 (1881). More dwarf and compact than the type, 
and destitute of rays. Lower California, Arizona, etc. 
The concluding series of species have a linear heath-like 
foliage, which gives them a rather peculiar appearance. 
Number 9 is the type of Nuttall’s Hricamera, a genus main- 
tained by Bentham and Hooker and some others; but I can 
can not separate this from those next preceding it in these 
pages, nor those from the typical Chrysoma. Numbers 9, 10 
and 11 were ranged by A. Gray under his Aplopappus for 
the reason that they have ligules. The others were placed in 
his Bigelovia because rays were wanting. That they are 
most strictly congeneric does not seem likely to be called in 
question. 
9. C. ericoides. Diplopappus ericoides, Less, Linnea, 
vi. 117 (1831). Aplopappus ericoides, Hook. & Arn. Bot. 
Beech. 146 (1833). Ericameria microphylla, Nutt. Trans. 
Am. Phil. Soe. vii. 329 (1840). Aster ericinus, O, Ktze. 1. ¢, 
313. Shrub of seacoast sandhills in middle California; the 
leaves slightly pubescent.
