CATALOGUE. ]21 
EPi,ospium PpaNicuLatuM, Nutt—Utah; San Luis Valley, Southern 
Colorado, at 6,400 feet altitude. 
ZauscuNERIA Cairornica, Presl—Extending from California to East- 
ern Arizona. 
GayopHyTuM RAMosissimum, T. & G.—Nevada; Colorado (150, 146, 
147). 
GAYOPHYTUM RACEMosuM, T. & G.—Utah. 
CENOTHERA BIENNIS, L.—Utah and San Luis Valley, Colorado (181, 
141). . Var. grandiflora, T. & G.—Nevada. 
Var. HIRsuTIssima, Gray. (C2. Hookeri, Torr. & Gray.)—Close to the 
last—i. ¢., var. grandiflora—but with a very hirsute ovary.—Sanoita Valley, 
Arizona (658). 
CENOTHERA sinvaTA, L., var. GRANDIFLORA, 8S. Watson.—A poor specimen 
of what I take to be the above is found in the collection from Arizona, 
though I find it has hardly free tips to the calyx-lobes, and the flowers are 
nodding in the bud; seeds not seen. In this and the next species, there is 
a great difference in the length of the styles in plants from the same imme- 
diate locality, though it hardly suggests the idea of dimorphism. 
CENOTHERA PINNATIFIDA, Nutt—Usually erect and somewhat branched, 
canescently pubescent and more or less hirsute; lower leaves petioled, entire, 
serrate or pinnatifid, upper ones linear-lanceolate, deeply and somewhat 
irregularly pinnatifid ; capsule sessile, linear, tapering, hirsute, 1’ long; calyx- 
tube slender, dilating gradually, 2’ long; petals white or rose color, 1’ in 
diameter ; calyx-lobes reflexed, not more than 1’ long, tips hardly free ; seeds 
yellow, strongly pitted, slightly apiculate and oval.—Southern Arizona 
(318, 377); Colorado (125). 
CENOTHERA TRICHOCALYX, Nutt.—Erect, 4° high, tomentose or somewhat 
canescent, hirsute ; leaves sessile, tapering (in my specimens) into a petiole, 
oblanceolate, sinuate, denticulate ; capsule sessile, linear, tapering upward 
slightly ; seeds in a single row; calyx-tube 13’ long, calyx-tips free, throat 
naked ; petals yellow, 13’ long. Mr. Watson, to whom I am so greatly 
indebted, doubtfully assigns this rather rare plant here, adding in his 
remarks that it is 1068 of Wright—Willow Spring, Arizona, at 7,195 feet 
altitude (223).
