GREENE FTELEA IN THE WEST AND SOUTHWEST. 75 



55. Ptelea bullata, sp< nov. 



puberulent 



lo&e; older brandies dark-brown, glaltrous: leaves of a ligbt and vivid green, lighter 

 beneath, glabrous on both faces exLX'pt for a apar^e short pubesceneeontlie midvein 

 beneath, sparsely gland-dotted and very nnnutely densely pnneticalate; terminal 

 leaflet elliptiedaneeolatej 5 to 6.5 cm. long, acnto at both ends, not very distinctly 

 subserrulate, the pair more than two-thirds as large, more or less inequilateral; flow- 

 ers many, in ample loose siibcoryndjose panicles, but these sessile, not equaling the 

 foliage: samaras suborbicular or inclining to round-obovate, abruptly acute, the base 

 truncate or subcordate, about 1.5 cm. long, 1.2 cm. wide above the middle; body 

 large, round-ovate, much wider than the width of the wing, puberulent, faintly cir- 

 cumvallate, gland-dotted oidy wdiile immature, in maturity finely transverse- 

 rugose, but the intervals between the ridges elevated above them and as if inflated. 



Anderson's Kanch, Lower Lake, Lake County, California, May 11, 1901, Agnes 

 Bowman; type specimen in tlie Herbarium of the California Academy; no others 

 seen. The species is a most notable one in the characters of its fruit, this being des- 

 titute of dot-like glands, and the surface of the capsular body rising in blisterdike 



elevations between theuncommoidy slender and low transverse ridges, all manifestly 

 quite normal. 



56. Ptelea cycloloma, sp. nov. 



Young twigs and other growing parts puberulent, even older twigs and branches 

 puberulent, dark-brown, tuberculate, but mature foliage more obscurely pubescent 

 or puberulent, yet not glabrous on cither face, wholly of a light but dull green; ter- 

 minal leaflet oblong, lanceolate, obtuse, but at base abruptly acutish, 4.5 to 6 cm. 

 long, somewhat crenulate, the pair about two-thirds as large, only slightly inequi- 

 lateral: samaras variable as to size, the smaller 1 cm., the larger L5 cm., wide, orbic- 

 ular, not notched or lobed or truncated at either end; body unusually large, 

 commonly almost obicular, its breadth nearly twice that of the wnng, also unusually 

 thick and double convex, with no trace of circumvallation, only a low transverse 

 rugosity but Avith copious and prominent gland-dots. 



Mountains near Mariposa in the Sierra Nevada, California, collected by J. W. 

 Congdon, the fruiting specimens in July, 1S93, the flowering in May, 1894; type in 

 the Herbarium of the California Academy, sheet no. 12214. The flow^ering speci- 

 mens are from the jjistillale shrub, and the stamens therefore unknown. The 

 species is most interesting, inasnmch as its fruits, with their unusually large and 

 thick nut-like bo<!y an<l narrow wing, make some approach, not however any near 

 apj^roach, to those of the more southerly I\ aptera. 



57. Ptelea nucifera, sp. nov. 



Itelea aptera Jirandogee, Proc. Cal. Acad, IL 2: 138. 1889, not Parry. 



Evidently a low^ stunted shrub, tlie branches of the season and leaf-bearing twigs 

 mostly less than an inch long, dark brown, puberulent, not strongly tuberculate; 

 flowers and early foliage not known: mature leaves subcoriaceous, small, the leaflets 

 very une(jual, the lateral pair usually greatly reduced and unequally so, the odd 

 leaflet narrowly obovate-oblong to obovate, lightly and not closely crenate, the 

 whole kaf glal^rous and coarsely gland-dotted above, scantily pubescent beneath: 

 fruits oval, 2 cm. long, very thick and nut-like, encircled by a distinct though narrow^ 

 wing, this and the body thickly beset with low tubercles frustulate at summit. 



Las Huevitas, Lower California, May 20, 1889, T. S. BrandtMgee. Type in the Her- 

 barium of the California Academy. It is mounted on the same sheet with some of 

 Dr, Parry's specim(^ns of his I\ aptera, and even the fruits of P. nucifera, all 

 detached from the twigs that supported them, have been recklessly placed within 

 the same pocket containing those of J\ aptera; but they are so different as to be
