GKEENE — PTELEA IN THE WEST AND SOUTHWEST. 67 



Kerrville, Texas, May H, 1894, A. A. Heller, in flower and perhap?^ nearly full- 

 ^rowu foliage; distributu^l uiider no. 1C90. In the mere outline of them the leaflets 

 recall those of P. helaUfoUa of Arizona, but the two are otherwise very unlike. 



31. Ptelea persicifolia, sp. nov 



Twigg of the reason light rhc«tnnt-eolor but dull and puberulent, finely rugulose: 

 foliage of a light green, ahnost subeoriaceoua, lighter beneath, and with scanty 

 pubescence of rather long hairs; odd leaflet somewhat broadly and elliptically lance- 

 olate, 5 to 7 cm. long, abruptly acuminate, the pair similar and not much smaller, 

 all sessile, subcntire: samaras nearly orbicular, obtuse at both emh, 2 cm. broad, 

 not quite as Inng; body round-oval, of less than the width of the wing, sinuout-ly 

 circumvallate, definitely transverse-rugose and strongly dotted; style twice as long 



as the stipe. 



Huntsville, Oklahoma, June 5, 189G, Laura A. Blankinship. Species in several 



respects peculiar, not easjy to place. Type in tlie National Herbarium. 



32. Ptelea subvestita, ap. nov. * 



Mature twigs of the season quite velvety, the indument concealing the evidently 

 lightly rugose and red-brown bark, the petioles also softly villous, and the lower face 

 of the leaves, these suhcoriaceous, glaucescent even above, and with mere traces of a 

 scattered pubescence beyond the veins and veinlets, the latter more distinctly pubes- 

 cent; odd leaflet rhombic-lanceolate to ellii>ticdanceolate, acute at both ends, 4 to 6 

 cm. long, lightly and often obscurely crenate, the pair inequilateral and obliquely 

 oval, small*T by about one-third; samaras suborbicular, 2 cm. long, more or less; 

 body oval, about as wide as the wing, indistinctly circumvallate, coarsely low-rugose, 

 the ridges not defiiutcly transverse, scantily and obscurely punctate ; style and stipe 



btith jirominent, subequal. 



Dry hills about Silver City and Fort Bayard, southern New [Mexico, the type 

 specimens collected by myself in jnaturc fruit, July 20, 1880, and preserved in the 

 Herbarium of the Califorida Acadeniv. Late in November of 1905 the same was col- 

 lected at Fort Bayard l)y Mr. J, C. Blumer, the twigs laden with mature fruit of the 

 largest dimensions, the foliage having jnostly fallen at that date; but the identity of 

 these specimens witli mine, as to the si^ecies, is certain, both from the twigs and 

 from such foliage as w^as preserved, 



33. Ptelea padifolia, sp. nov. 



Growing twigs delicately but densely puberulent under a not si^ar^e indument of 

 hirsute hairs Avhicb is deciduous, those of the second seasun wholly divested of the 

 hirsute hairs, only puberulent, even obscurely so, the red-brown bark appearing 

 glabrous, scarcely at all rugulose or glandular: leaves of a vivid green above, nearly 

 glabrous, some short hirtellous hairs along the Tuidvein, and a few more short and 

 appressed scattered over the surface, the lower face pale an<l almost hoary with a 

 minute villous tomeiitum; odd leaflet from narrowly crenate-obovate to almost 

 rhomboid- lanceolate, 5 to 7 cm. long, cusindately acute, the pair smaller by from 

 one-fourth to one-third, mostlv obligue-oval and pointless, all neatly and evenly 

 crenulatc: sanuiras not ijuite mature but full-grown roun.l-oval, nearly 2 cm. long, 

 1.8 cm. wide; body broa<boval, n.jt as wide as the Aving; style and stipe equal. 



Western Texas, in the canyon of the Rio Limi)ia, April 20, 1902, S. M. Tracy and 

 F. S. Earle, no. 272, as in my herliarium (ty]>e) and the National Herbarium. 



Most unlike all other species of Texas regions westward in its thin deep-gruen 

 foliage; this by its slender whiti.^h veins, evenly creimlate margins, and even by the 

 outhne of the terminal leaflets, readily recalls that of some of the so-called wild 

 cherries.
