376 BOTANICAL GAZETTE [ DECEMBER 
one-nerved, somewhat involute and usually more or less twisted, 
irregularly and widely divaricate, very numerous on the new 
wood and often fascicled on two-year old branches, short, rarely 
exceeding 3, usually much shorter: inflorescence and bracts 
much as in the species. 
This is what has often been called in this range Bigelovia Douglasit 
stenophylla Gray. I have distributed some specimens under that name, but 
I am now satisfied that that is a very different plant and belongs to a more 
western range.’ It occurs mostly on dry ridges and stony or sandy slopes. 
Type of the variety is no. 1847, Centennial valley, August 26, 1895. Another 
collection is no. 4434. 
CHRYSOTHAMNUS PUMILUS acuminatus, n. var.— The habit of 
the species: numerous slender stems from a woody base 2-3" 
high, with whitish bark: leaves numerous but early deciduous 
below, crowded toward the inflorescence, nearly filiform, ascend- 
ing, somewhat twisted, 2-3™ long: inflorescence more paniculate 
than in the species; bracts lanceolate, long-acuminate with more 
or less spreading tips, nearly equaling the 5-6 flowered disk. 
This variety I have from La Veta, Colorado, only, collected by Professor 
C. S. Crandall, August 21, 1897. 
CHRYSOTHAMNUS LANCEOLATUS Nutt. 1. c.—I see no reason 
for reducing this to a variety. Numerous collections of it show 
as much constancy in the essential characters as most of the 
recognized species. Its low tufted habit, its uniformly scabro- 
puberulent surface, and its either plane or twisted lanceolate 
leaves make it not hard to recognize. Specimens by the writer, 
nos. 889, 905, 2672, 2793, 5294 and 5314 are representative, 4

material was at hand, but it has since been secured in abun 
The characters as given are well borne out, except that in cl 
specimens the leaves are less glaucous. ‘ 
5I think it should be noted that C. viscidiflorus Nutt. l.c. (Bigelovia D om glass 
Gray) occurs probably in a range to the northwest of that now under oe 
and that several of its varieties, though often attributed to the eastern peur 
not in this range at all. Among such may be named vars. latifolius, serrulatus, 
tortifolius.
