turgid-oval or subglobose, apiculate, longitudinally striate-ribbcd, and punctate 

 between the ribs. 



CE. coRONOPiFOLiA ; var. calycibus hirsuto-villosis seu villosissimis. — Valley of 

 the Pecos, in alluvial soil ; June. (1070.) — Seeds striate and punctate, as in the 

 preceding. 



CE. ROSEA, Ait. ; DC. Prodr. 3. jj. 51. Hartmannia gauroides, Spach, Monogr. 

 Onagr. p. 41. On steep banks of the San Pedro, Sonora; Sept. (1071.) — Also 

 collected by Coulter (No. 165), and by Gregg (Saltillo, and San Angel, near 

 Mexico). 



CE. (Megapterium) Wrightii (sp. nov.) : subcaulescens e caudice perenni, cinereo- 

 puberula ; foliis lanceolato-oblongis acutis mucronatis venosis dentatis basi plerum- 

 que laciniatis seu lyrato-pinnatifidis petiolatis ; laciniis calycis tubo multo brcviori- 

 bus petala flabelliformia subtequantibus ; capsula immatura quadrialata. — Stony 

 hills, near the copper mines, New Mexico; Aug. (1072.) — "Flowers open in the 

 morning, withering early." The corolla is evidently yellow, and turns faintly rose- 

 colored in fading, about as large as in CE. Missouriensis (namely 2 to 2^ inches long), 

 the calyx (tube 5 or 6 inches long), stamens, stigmas, and immature seeds likewise 

 similar. The leaves are herbaceous in texture, from 5 to 11 inches long, including 

 the short petiole, an inch to an inch and a half wide, repand-denticulate or sharply 

 and even doubly toothed, and commonly with 2 to 6 narrow and sharp lobes at the 

 tapering base. The few and very immature capsules are sessile, an inch long, half 

 an inch wide when flattened, canescent or sparsely tiairy ; the wings two lines wide, 

 but obviously not fully developed. 



CE. Wrightii ; var. vernalis, minor, magis canescens ; foliis brevioribus ovatis 

 oblongisve integerrimis vel plerisque lyratis. — Stony hills near Frontera, New 

 Mexico; April. (1374.) — Root or caudex stout and deeply descending, bearing a 

 rosulate tuft of leaves of 3 or 4 inches in length, and numerous flowers and young 

 pods, and beginning to show short stems. Flowers smaller than in the foregoing ; 

 the petals scarcely more than an inch and a half in length. Immature pods an inch 

 and a half long, about half an inch wide, narrowly ovate-oblong, tapering to the 

 summit, sessile, cinereous-puberulent, 4-winged, the wings 2 to 3 lines in width ; 

 the texture chartaceo-coriaceous. Seeds packed in a double row in each cell, 

 angled, with a thick testa, transversely corrugate below, the upper part winged in 

 the manner of CE. Missouriensis, hut more decidedly so. — I can scarcely doubt that 

 this is a vernal form of the preceding, and that it should be referred to the section 

 Megapterium, although the wings of the pod are narrow. Except in the fruit it 

 much resembles the following, which indeed belongs to the same section rather 

 than to Lavauxia. 



CE. brachycarpa, Grai/, PI. Wrifjht. p. 70. Hill-sides on the Limpio ; June. 

 (1073.) — " Flowers expand about sunset." A specimen of this was also gatliercd 

 on the mountains east of El Paso, in fruit. May. The larger pods are nearly an 

 inch in length, cartilaginous in texture, with pretty thick walls ; the angles very 

 narrowly but distinctly winged. Seeds much as in the preceding, but Avith a thick- 

 ened crest-like apex with a sharp edge, rather than winged.
