plants collected by Coulter, and will soon be described by Mr. 
Harvey and Dr. Gray. This is distinguished from the others by 
numerous ray-flowers, and is the B. multiradiata, Harv. and Gr. 
The whole plant is clothed with a woolly pubescence, and varies: 
from a few inches to a foot or more in height. The leaves are 
somewhat pinnatately cut into several-narrow segments. The heads 
are on long naked peduncles, and when the raysare fully expanded: 
are more than an inch and a half in diameter. The rays are 40 or 
50 in number, in two or more series, obovate cuneate, of a bright 
orange yellow, and 7-nerved, carolla of the disk, flowers with five 
short segments which are glandulary pubescent, with intra-margi- 
nal nerves. Branches of the style short, somewhat dilated and 
truncate at the extremity. Very abundant along the Del Norte 
and in the dividing region between the waters of the Del Norte 
and those of the Gila. Flowers from October 4th to November. 
Zinnia grandiflora. Mutt. in Amer. Phil. trans. (n. ser.) 7, p. 
348; Torr. and Gray ft. N. Amer. 2, p. 298. Valley of the Del 
Norte. This plant, which was first detected by Dr. James in Long’s. 
first expedition, is certainly frubescent at the base; in which re- 
spect it resembles the nearly allied Z. linearis, Benth. plant Hartw., 
No.47. This is the most humble species of the genus; being not 
more than six inches high. The stem is branching and rigid. The 
leaves are linear, sessile, and somewhat connate at the base, 
strongly 3-nerved, and glandularly punctate. Heads mostly solitary 
at the summit of the branches, on short peduncles. Involucre 
ovoid-cylindrical; the scales about 8, closely imbricated; outer ones 
somewhat orbicular; the inner oblong, ciliate, and somewhat scari- 
ous on the margin. Ray flowers 3-5, coriaceous and persistent, 
roundish-ovate, emarginate, continuous with the summit of: the - 
achenium. Disk flowers few. Lobes of the corolla villous. An- 
thers yellows. Branches of the style tapering into a subulate-lanceo- 
late point, hairy above the middle. Achenia obcompressed, scarcely 
winged, scabrous; the outer integument thin; those of the ray 
naked, of the disk with a single awn. :
