GREENE PTELEA IN THE WE81 AND SOUTHWEST. 67 



Kerrville, Texas, May 3, L894, A. A. Heller, in flower and perhaps nearly full- 

 grown foliage; distributed under no. 1690. In the mere outline of them tie- leaflets 

 recall those of /'. &< tulifolia <»f Arizona, bu1 tin- two are otherwise very unlike. 



31. Ptelea persicifolia, sp. nov 



Twigs "!' the season light chestnut-color bul dull and puberulent, finely rugulose: 

 foliage <>f a lighl green, almost subcoriaceous, Lighter beneath, and with scanty 

 pubescence <»f rather long hairs; odd leaflet somewhat broadly and elliptically lance- 

 olate, 5 t" 7 cm. long, abruptly acuminate, the pair similar and nol much smaller, 

 all sessile, sabentire: samaras nearly orbicular, obtuse at both ends, - cm. broad, 

 not quite as long; body round-oval, of less than the width of the wing, sinuously 

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

 as the stipe. 



Huntsville, Oklahoma, June 5, L896, Laura A. Blankinship. Species in several 

 respects peculiar, not easy to place. Type in the National Herbarium. 



32. Ptelea subvestita, sp. nov. 



Mature twin's of tin- season quite velvety, the indument concealing tin- evidently 

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

 of the leaves, these subcoriaceous, glaucescenl 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 elliptic-lanceolate, acute at both ends, 1 to 6 

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

 oval, smaller 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 definitely transverse, scantily and obscurely punctate ; style and stipe 

 both prominent, subequal. 



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

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

 Herbarium of the California Academy. Late in November of 1905 the same was col- 

 lected at Fort Bayard by Mr. J. C. Blumer, the twi;_ r s laden with mature fruit of the 

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

 these specimens with mine, as to the species, is certain, both from the twigs and 

 from such foliage as was preserved. 



33. Ptelea padifolia, sp. nov. 



Growing twigs delicately but densely puberulent under a not sparse indument of 



hirsute hairs which is deciduous, those of the second season wholly dive-ted 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 midvein, and a few more short and 

 appressed scattered over the surface, the lower face pale and almost hoary with a 

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

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

 one-fourth to one-third, mostly oblique-oval and pointless, all neatly and evenly 

 crenulate: samaras not quite mature but full-grown round-oval, nearly 2 cm. long, 

 1.8 cm. wid« ; body broad-oval, not as wide as the wing; style and stipe equal. 



Western Texas, in the canyon of the Rio Limpia, April 26, L902, S. M. Tracy and 

 F. S. Earle, no. 272, as in my herbarium (type) and the National Herbarium. 



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

 foliage; this by its slender whitish veins, evenly crenulate margins, and even by the 

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

 cherries.
