CATALOGUE. J 21 



Epilobium paniculatum, Nutt. — Utah; San Luis Valley, Southern 

 Colorado, at 6,400 feet altitude. 



Zauschnebia Califobnica, Presl. — Extending from California to East- 

 ern Arizona. 



Gayophytum ramosissimum, T. & G. — Nevada ; Colorado (150, 146, 

 147). 



Gayophytum kacemosum, T. & G. — Utah. 



QEnotheea biennis, L. — Utah and San Luis Valley, Colorado (131, 

 141). Var. grandiflora, T. & Gr. — Nevada. 



Var. hiesutissima, Gray. ((E. HooJceri, Torr. & Gray.) — Close to the 

 last — i. e., var. grandiflora — but with a very hirsute ovary. — Sanoita Valley, 

 Arizona (658). 



(Enotheea sinuata, L., var. grandiflora, S. 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. 



(Enothera 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, l'long; calyx- 

 tube slender, dilating gradually, 2' long ; petals white or rose color, V 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). 



(Enothera teichocalyx, 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 If long, calyx-tips free, throat 

 naked ; petals yellow, 1 J' 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).
