74 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM 



The type, and only known Bpecimen, I find on Bheel 321, National Herbarium, 

 collected in California in i s 7."> by <b R. Vasey, no other data given; in all the 

 valuable collection of Californian Ptelea belonging to the < lalifornia Academy there is 

 nothing Bhowing approach to this in respect to either ita broad and large oval leaflets 

 or its transversely elongated Bamaras. 



53. Ptelea cinnamoniea, sp. nov. 



'1'w iga ol the Beason oi a ratlin- bright cinnamon-red, glabrous, rugose and glandu- 

 lar-tuberculate l>ut polished, those a year old Bimilar l>ut darker and no1 Bhining: 

 - thin, of a vivid light-green above, paler beneath, copiously glandular and the 

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

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

 those of the lower and fruiting branches, elliptic-lanceolate on vigorous sterile Bhoots, 

 always obtuse, lightly crenate, the pair two-thirds as large, only slightly inequilateral: 

 samara from Buborbicular to somewhat obovate, aboul is nun. long, obtuse at base, at 

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

 the wing, the body very large, much \\ ider than the width of the w im_ r . Buborbicular 

 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, Ernesi Braun- 

 ton; type in the National Herbarium.

Ptelea angustifolia Brew. A Wats. Bot. Cal. 1:97. 1876, in pan. not Benth. 

 Ptelea crenulata Greene, Pittonia 1: 216. 1888; Flora Franciscans 75. 1891; Man. Kay- 

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



Young twins gland-dotted and sparsely hirtellons-villons. those of the second Bea- 



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

 notably unequal, 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 pnbernlent, the feather veins strongly divergent and 

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

 largest and most vigorous specimens doubly subserrate crenulate, the apes 

 acute or in some obtusish: branches of the inflorescence and tin- pedicels minutely 

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

 1.4 to L.6 cm. wide, the length from slightly less to a trifle more, not flat but dis- 

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

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

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

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

 shallow furrow, the whole moderately gland-dotted and pnbernlent; style and stipe 

 short, equal. 



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

 light of perfect 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 Merriam. Its habitat on that 

 mountain seem- t-» be in Mitchell's Canyon, on the northward slope, and, as Dr. 

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

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

 L903, the distribution numbers being 2942 and 2943. The species appears to occur 

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



Number 5564 of Heller <S Brown, from the Marysville Buttes, distributed for P, 

 crenulata, [suspect may represent another and a more local Bpecies; but the speci- 

 men- are, as usual, in (lower only. A like degree of uncertainty exists in relation to 



a sheet from Kaweah, Tulare County, collected h\ Miss Eastwood, April, 1896.
