 Sainndus fljiSHSfi/o/iiis, Losqs., Anunal Keport, 1«3, p. 4ir.. 



Leaves iinpari-pinnate; leaflets slightly nuu.braDaceous, lauceolal., acuminate, very entire, ses- 

 sile or attacbeil to tbe raeliis by a uarrowcU, winged base. 



The species is repre^^eiilcl in iiuuiorou.^ spcoimcus by leaflets varying in 

 size from two and a half 1(. nine (■.•ntiinclers long, lanceolate or linear-lance- 

 olate, graclnally acuminate, inequilateral, but not falcate, sometimes merely 

 slightly eurvea at the point, enlarged in the upper side, and narrowed to a 

 ses'lile base, which is generally prolonged into a short, winged petiole. The 

 rachis is ilat, not winged. The nervation and areolation are of the same type 

 as figured by Heer for S. falcifoUvs (Fl. Tert. Ilelv., iii, pi. cxix, fig. 1 h), a 

 species to which this one is closely allied, especially ditlbring by the smaller 



size of its sessile leaves. 



Habitat— Castello's Ranch, Colorado {Prof. E. D. Cope). Middle Park, 



near Florissant, Colorado (Dr. F. V. Hayden).

 Sapindua coriaceua, Lesqx., Annual Report, 1873, p. 415. 



Leaflets bar.l, coriaeeous, oblong-lanceolate, very entire, more or less flistinetly ineqnilateral, 

 short-petioled; borders reflexed ; middle nerve thick; lateral veins scarcely d.scern.ble; surtaeo 

 polished. 



These fragments of leaflets have about the same form as those of the 

 former species, but are easily identifie.l by their hard, leathery texture, and 

 the distinct, though short petiole. They are generally larger, and appear 

 gradually narrowed to a short acumen. All the specimens are brokt-n, and 

 none represent the upper part of a leaflet. The rachis also has not been 

 observed. The lateral veins arc scarcely discernible through the texture of 

 Ihc leaves. All that could l)e seen of them is figured. 



Habitat.— Elko Station, Nevada {Prof. E. V. Cope), in connection with 

 Planera longifolia, Sequoia angustifolia, Taxodium duhium, etc.

Sapindus Dentoni, Lesqx., Annuiil Report, 1874, p. ;U.''>. 



Leaflets with entire or slightly nndnlate borders, lanceolate, gradnally tapering to a long acnn.en 

 ronnded to the base and narrowed to a short petiole; lateral nerves elo.e, parallel, neatly straight to 

 the bordeis, where they abruptly curve. 



By the shape and the size of the leaflets, this species is related lo <S.
