Sapiiidns candatns, Lesqz. 

 Plate XLVIII, Fig. 6. 

 Sapindaa caiidatus, Lesqs., Annual Report, l!:i72, pp. 380, 397. 



Leatlet8 somewhat thick and membranaceous, sessile, very entire, inequilateral, rounded to the 

 base, oval-oblong, abruptly narrowed into a long, sharply pointed acumen. 



The leaf i.s comparatively large, eleven centimeters long, four and a 

 half centimeters broad, one of the sides ineasuring two centimeters; for, 

 like all our fossil species, it is inequilateral, entire, and with a pinnate, camp- 

 todrome nervation. By its form and nervation, it resembles S. falcifolhis, Al. 

 Br. in Heer, Fl. Tert. Ilelv., p. 61, pi. cxix, the areolation being of the same 

 character as in fig. 1 b. But the leaflet was evidently sessile, like those of 

 S. densifolius of the same work (pi. cxx), and it differs from both by its 

 scarcely falcate outline, its broader size, and its long, narrow acumen. 



Habitat. — Golden, Colorado, and Black Buttes, Wyoming.

 Plate XLIX, Fig. 1 . 

 Sapiudus anguaUf alius, Lesqx., Annual Report, 1873, p. 415. 



Leaves small, linear, imparl pinnate; leaflets mostly alternate, lanceolate, acuminate, rounded in 

 narrowing to a sessile base ; nervation obsolete. 



The branch (fig. 1) seems to represent a fascicle of leaves not yet fully 

 developed. Its connection with the leaflet (fig. 2) upon the same specimen, 

 and also the size of that of fig. 3, which is intermediate, seemed to author- 

 ize the reference of the branches and leaflet to the same species. I have, 

 however, received lately, from a different locality, a specimen which contra- 

 dicts this reference. It represents one branch bearing leaflets, and some 

 detached ones of the same characters and size as those of fig. 1. The branch 

 is fully developed; the rachis, flattened by compression, somewhat broader; 

 the leaflets are sessile, in odd number, and no remains of the following species 

 are mixed with them. The characters are moreover somewhat different from 

 those of S. angustifolius ; the leaflets, sessile, without prolongation of the 

 narrowed base, are thin, nearly equilateral, and therefore I now consider this 

 union of the leaflets of two species closely allied in characters as casual. The 

 leaflets of this species are largest nearer their base, anil more abruptly rounded 

 to the point of attachment; tlic point is more acute and less prolonged. 



Habitat. — Near Florissant, South Park, Colorado {Trof. E. D. Cope). 

 Near Castello's Ranch, Colorado {Prof. W. A. Brownell).
