above, the numerous short-pedicellate heads rather large: 
stem glabrous below, the branches of the inflorescence 
coarsely pubescent in lines: leaves linear-lanceolate, acute, 
of firm texture, slightly curved, the lowest 3 or 4 inches 
long, evenly and sharply serrate, those of the branches and 
branchlets perfectly entire, very closely stiffly and sharply 
setose-ciliolate: campanulate involueres 4 inch high, their 
linear bracts in 2 or 3 series but nearly equal, the outer 
sometimes wholly herbaceous, the inner with dark-green 
tip and midnerve: rays about 30, pale-purplish or flesh-color. 
Meadows about San Bernardino, California, S. B. Parish, 
n. 3,818. Confused with his A. hesperius, by Asa Gray, but 
very distinct from that Rocky Mountain type by its rigid 
sword-shaped and sharply edged leaves, the lowest of which 
are sharply serrate. It is a Pacific Coast homologue of 
the eastern 4. paniculatus. 
CORRECTIONS IN NOMENCLATURE.— III. 
The name Oreastrum, employed by me on pages 146 and 
147 of the third volume of this series to designate a genus, 
I find to have been practically preoccupied; for it can not 
be maintained as different from the Oriastrum of Poeppig 
& Endlicher. I therefore propose OREosTEMMA as a con- 
venient substitute for my former and untenable Oreastrum ; 
the species to be named thus: 
O. ALPIGENUM. Aster alpigenus, Gray. 
O. HavpENr. Aster Haydeni, Porter. A. pulchellus, D. C., 
Eaton. 
O. ANDERSONIL Aster Andersonii, Gray. 
O. ELATUM. Oreastrum elatum, Greene.
