118 LEAFLETS. 
teeth or small lobes about midway, otherwise quite entire, dark 
green above and there glabrous except a minute but rather 
dense curled pubescence on all primary veins, beneath paler, 
the veins by no means sparsely hirsute with straight and rather 
coarse spreading hairs: fruits uncommonly small, subglobose 
but the length distinctly greater than the thickness, not um- 
bilicate, capitellate-mucronate, very smooth and shining, neither 
obviously striate nor wrinkled. 
Low woods in Riley Co., Kansas, J. B. Norton, 28 Sept., 1895, 
as in U. S. Herb., a fine fruiting specimen; also the same in 
flower, from the same station, 1896, the date not given. 
Fine species with altogether peculiar small fruit, and very large 
foliage strongly recalling that of Megundo. 
T. LONGIPES. Leafy branches reddish loosely puberulent 
and obviously lenticellate, the older brown, glabrous and the 
lenticels obscure: leaves small, on remarkably elongated peti- 
oles, these very firm and erect, 4 to 5 inches long, the length of 
the leaflets less than 2 inches, the terminal mostly on a petio- 
lule conspicuously shorter than that of the laterals, all the 
leaflets broadly ovate, cuspidately acute, coarsely and quite regu- 
larly serrate-dentate from near the base up to the apical cusp, 
dull pale green on both faces, wholly glabrous beneath, almost 
so above, but with a few strigose hairs on the surface, becoming 
more numerous at the margin: fruits of middle size, spherical, 
neither striate nor wrinkled nor shining but straw-colored and 
unpolished. 
Species from a cañon south of Glenwood, Utah, collected by 
L. F. Ward, 12 June, 1875, as in U. S. Herb., and a remark- 
able one in respect to characters both of foliage and fruit. 
T. HESPERIUM. Stems and foliage in every way twice the 
size of those of 7. Rydbergit, the petioles greatly elongated : 
branches of a fine pinkish brown the first season, glabrous or 
nearly so, striate-angled, closely and ‘finely lenticellate: leaves 
of very firm texture and vivid-green, the leaflets commonly 
round-ovate, 3 or 4 inches long, 2 or 3 in width, subtruncate or 
rounded at base, cuspidately acute, either quite entire or coarsely 
toothed, the teeth more often inclining to crenate than serrate,
