CE. TRILOBA, Nutt. ; Gray, PI. Wriffht. p. 70. Valley between the Salado and 

 Lake Santa Maria, Chihuahua; April. (1375.) — This species has never before 

 been found in the New Mexican region. 



OE. (Pachylophis'?) primiveris (sp. nov.): acaulescens, pygmaea, annua vel bien- 

 nis ; radice exili ; foliis lyrato-pinnatifidis vel primordialibus integris lanceolato-ob- 

 longis ad margines costamque cum calyce villoso-pubescentibus ; tube calycis filiformi 

 lobis (petala flava subpequantibus) multoties longioribus ; capsulis ovoideo-conicis 

 acutis leviter 10-costatis in cello sessilibus ; seminibus ad chalazam suberoso-cristatis. 



— Dry hills near El Paso, Feb. - April. (1376.) — This little plant evidently springs 

 from the seed in the autumn, or even in the winter, and flowers at the first opening 

 of spring. Some of the specimens are barely an inch high ; the leaves of the larger 

 ones attain the length of 3 or 4 inches ; and the tube of the calyx is one or two 

 inches long. The petals, from 5 to 8 lines long, are pure yellow, not turning pur- 

 plish. Anthers linear, fixed by the middle. Lobes of the stigma linear, distinct. 

 Capsule 8 or 10 lines long, tapering from near the base to the apex, terete, some- 

 what hirsute, coriaceous ; the ribs filiform, equal, not crested nor tuberculate. 

 Seeds very numerous and biserial in each cell, oval, with a thick and rather corky 

 testa, somewhat rugose, grooved along the rhaphe, and enlarged into a thick and 

 short appendage at the chalaza. The plant is strictly acaulescent and probably 

 disappears by the end of spring. The leaves become glabrate. Strictly speaking, 

 this belongs to a new section analogous to Pachylophis.

 multoties longiore ; petalis spathulato-oblongis integerrimis calycem stylumque 

 sequantibus ; capsulis elongatis filiformibus rectis sessilibus. — Stony hills along the 

 Rio Grande near El Paso; March. (1377.) — Plant a span, or at length 9 or 10 

 inches high, erect, or the side branches from the base ascending, with wholly the as- 

 pect of a small Epilobium ; the branches slightly viscous-pubescent. Radical leaves 

 li to 2 inches long, 3 to 5 lines wide ; the cauline smaller ; the later floral linear- 

 subulate, much shorter than the ovary, and like it pruinose-puberulent. Calyx- 

 tube scarcely a line and a half long. Petals less than a line long. Stigma large, 

 globular. Pods H to 2 inches long, filiform, terete, half a line in diameter, erect-
