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 

 bat 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 Negutido. 



T. LONGiPES. Leafy branches reddish loosely puberuleat 

 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 3 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 cafion south of Glenwood, Utah, collected by 

 L. F. Ward, VI 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 T. Rydbergii, 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 leafiets 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.
