l)a.sally; disc bracts ordinarj^ pointed, witliout lateral lolx^s or teeth. 
Achenes perfectly jflahrous; papj)us-scales nearly two-thirds the length of 
the disc corollas, two in nntnher, without intermediate stpiainellae, hnt 
the ray achenes are trigonal, and regularly ])osses'.s three j)ai)i)ns scale.s; 
disc yellow; rays bright orange. 
\ cry common at the tyjH' locality, few miles east of llonlder, Colo¬ 
rado. Type, i\o. I, Cockerell.* 
Helianthus coloradensis andrewsi var. nov. 
Rays deep orange, a mnch richer color than the tyi)e. Ronlder (D. 1\I. 
Andrews). Type, No. 2, Cockerell. 
Ibis is possibly a western subspecies of Jf. grossescri'atus, hut the leaves 
are only leehly dentate and beneath are scalwous and hardly pallid. It 
is not known that the plant meets the range of typical grosseserratus; 
hut if it does, and intermediates are found, it will still be a question 
whether they are not hybrids. The ecological position of the plant is 
distiiict, as well as some of the characters. According to Greene’s de¬ 
scription of ir. fascicularis, that species diflers by the solitary stems, 
only two or three feet high; leaves all (so far as the description shows) 
opposite, the blades 8-6 inches long (9 inches long in coloradermis) ; heads 
1 to 8 (many in coloradensis) ; bracts mostly apj^tressed (loose and spread¬ 
ing in cofo?-adcnsfs); pappus scales shorter. Comparing IL coloradensis 
with //. utahensis (fascicularis), as described by Nelson, the same differ¬ 
ences appear, and in addition the disc of utahensis is said to he yellowi.sh 
brown, whereas it is yellow in coloradensis. Later, Nelson has referred 
both fascicularis and utahensis to H. nuttalli.f I am indebted to Mr. 
O.sterhout for the loan of a cotype of II. fascicularis, from Gunnison, 
Colorado, 7680 ft., August 16 (T8aker, 816). Some of the characters sup¬ 
posed to he distinctive do not hold; the upper leaves are alternate, and 
the plant carries six heads. The color of the disc does not appear to 
differ from that of H. coloradensis. On the other hand, the stature is 
very much less than in coloradensis ; a fully mature plant is 8 feet 6 
inches high. The iuvolucral bracts are more or less spreading, at least 
the outer ones; hut they do not extend conspicuously beyond the head 
in hud as they do in coloradensis. Tins difference is equally evident on 
comparison with a head of Id. fascicularis from the Alogollon Mts., 
Socorro Co., New Mexico (Wootou), kindly sent by Mr. Standley. The 
leaf blades of the cotyi)e fascicularis are about 4 inches long and % inch 
broad, narrowly acuminate at both ends, with the suhhasal lateral nerv- 
ures coming off at a very acute aiigle, in entire contrast with the other 
♦ I have no permanent lierbariinn, and all my plant typos, so far as I have control 
of them, will go to the U. S. National Museum. 
t On the Pacific coast the niUlallii group is represented by II. cnliforniais, for fresh 
material of which (grown in the garden of the University of ('alifornia) 1 am indebted 
to Dr. H. M. Hall. This plant is remarkahlo for having the achenes of the i-ay florets 
wholly without pappus scales, even in bud; the disc; achenes have the usual pair of 
long pointed pappus scales. The involucral bracts are sparsely hairy, hut not ciliate.
