74 CONTRIBUTIONS FEOII THE NATIONAL HERBARIUM. 



The type, and only known t^peciinion, I find on ^beet :]21, National IIerl>ariuin, 

 collected in California in 1875 by G. R. Vat-ey, no other data given; in all the 

 valuable collection of Californian Ptelea belonging to the Uallfurnia Academy there is 

 nothing showing approach to this in respect to either its broad and large oval leaflets 

 or its transversely elongated samaras. 



63. Ptelea cinnamomea, sp. nov. 



Twigs of the season of a rather bright cinnamon-red, glabrous, rugose and glandu- 

 lar-tuberculate but polished, those a year old similar but darker and not shining: 

 leaves thin, of a vivid light-green above, paler beni^atli, copiously glandular and the 

 glands colorless and pellucid, obscurely puberulent along the veins beneath, glabrous 

 and shining above; middle leaflet 5 to 7.5 em. long, obovate-oblong and obtuse as to 

 those of the lower and fruiting branches, elliptic-lanceolate on ^'igorons sterile shoots, 

 always obtuse, lightly crenate, the pair two-thirds air largo, only slightly inequilateral: 

 samara from suborbicular to somewhat obovate, about 18 nun. long, obtuse at base, at 

 apex subulate-pointed, by the projecting style pervading a cusp-like continuation of 

 the wingj the body very large, much wider than the widtli i»f the wing, suborbicular 

 to round-obovate, the usual transverse ridges faint, apt to be broken into something 

 like a reticulation, the intervals strongly glandular. 



Vicinity of lone, California, in the foothills of the Sierra, June, 1904, ]^>nest Braun- 

 ton; type in the National Herbarium. 



54* Ptelea crenulata Greene, Pittonia 1: 216. 1888. 



Pielea angmlifolia Brew. & Wats. Bot. Cal. 1: 97. 1876, in part, not Benth. 



Ptelea crenulata Greene, Pittonia 1 : 21G. 1888; Flora Franciscana 75. 1891; Man. Hay- 

 Reg. 72. 1894, of all in part only. 



Young twigs gland-dotted and sparsely hirtellous-villous, those of the second sea- 

 son dark brown or blackish, glabrate, glandular-tuberculate and rugulose: leaflets 

 notably unecpiab the laterals one-third to two-thirds the size of the terminal, this 4 

 to 7 cm. long, broadly to narrowly cuneate-obovate, all of rather light vivid green, 

 gland-dotted and more or less puberulent, the feather veins strongly <livergent and 

 on the lower face whitish antl very conspicuous, the margins crenulate, or in the 

 largest and most vigorous specimens doubly subserrate crenulate, the apex 

 acute or in some obtuaish: brant'hes of the inflorescence and the pedicels minutely 

 hirtellous: filaments hirsutulous from base to above the middle: samara orbicular, 

 1.4 to 1.6 cm, wide, the length from slightly less to a trifle more, not flat but dis- 

 tinctly concavo-convex, sometimes a little retuse at both ends, sometimes at neither; 

 body very large and thick, of nearly or quite twice the width of the wing, very 

 broadly round-oval or almost orbicular, not circumvallate, closely but irregularly 

 transverse-rugose and also marked, at least from the njiddle upward, by a broad, 

 shallow furrow, the wdiole moderately gland-dotted an<l ])uberulent; style and stipe 

 short, equal. 



The description of this more connnon Californian species is here completed in the 

 light of lu^rfect material from Mount Diablo, partly as collected by the late Dr. 

 Parry, July 4, 1872, and partly from a pocket of many mature samaras brought 

 from the same locality, October, 1898, by Dr. C. Hart ^lerriam. Its liabitat on tinit 

 mountain seems to be in Mitchell's Canyon, on tlie northward slope, and, as Dr. 

 Merriam informs me, at an elevation of about 300 meters. Flowering specimens 

 were distributed from this station by C. F. Baker, collected by himself in April, 

 1903, the distribution numbers being 2942 and 2943. The species apjicars to occur 

 at various other places up and down the Coast Range of middle California. 



Number 5564 of Heller tt Brown, from the Marysville Buttes, distributed for P. 



crenulata, I suspect may represent another and a more local species; but the speci- 

 mens are, as usual, in flower only. A like degree of uncerbiinty exists in relation to 

 a sheet from Kaweah, Tulare County, collected by Miss Eastwood, April, ]>i\)b.
