&BEENE -PTELEA IN THE WEST AND SOUTHWEST. 



55. Ptelea bullata, Bp. QOV. 



Shrub dioecious, the male aol known: growing twigs obscurel) puberulent, rugu- 

 lose; older branches dark-brown, glabrous: leaves of a lighl and vivid green, lighter 

 beneath, glabrous on both faces excepl for a sparse Bhorl pubescence od the midvein 

 beneath, sparsely gland-dotted and very minutely densely puncticulate; terminal 

 Leaflet elliptic-lanceolate, 5 to 6.5 cm. long, acute at both ends, nol very distinctly 

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

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

 foliage: samaras subortyicular «>r inclining to round-obovate, abruptly acute, the base 

 truncate or Bubcordate, about L.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 only while Immature, in maturity finely transverse- 

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



Anderson's Ranch, Lower Lake, Lake County, California, May II, L901, Agnes 

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

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

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

 elevation- between the uncommonly slender and low transverse ridges, all manifestly 

 quite normal. 



56. Ptelea cycloloma, Bp. nov. 



Young twigs an<l 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 either face, wholly of a light but dull green; ter- 

 minal Leaflet oblong, lanceolate, obtuse, but at base abruptly acutish, 4.r> 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 1.5 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 wing, also unusually 

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

 rugosity but with copious and prominent gland-dots. 



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

 Congdon, the fruiting specimens in .Inly, 1893, the flowering in May, 1894; type in 

 the Herbarium of the California Academy, sheet no. 12214. The flowering speci- 

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

 Species is most interesting, inasmuch as its fruits, with their unusually large and 

 thick nut-like body and narrow wing, make some approach, not however any near 

 approach, to those of the more southerly /'. <n>\>i-<i. 



57. Ptelea nucifera, Bp. nov. 



Ptelea aptera Brandegee, Proc. Cal. Acad. II. 2: 138. 1889, not Parry. 



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

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

 flowers and early foliage not know n: mature leaves subcoriaceous, small, the leaf let- 

 very unequal, the lateral pair usually greatly reduced and unequally so, the odd 

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

 whole Leaf glabrous and coarsely gland-dotted above, scantily pubescent beneath, 

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

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



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

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

 Dr. Parry's specimens of his /'. aptera, and even the fruits oi /'. nucifera, all 

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

 the same pocket containing those of /'. aptera; but they are so different a- to be
