 F. discolor, Muhl. Cat. 111. — Rich or moist woods, Canada to Florida and Lovusiana. Very 

 valuable timber-tree : fruit variable in size and shape of wing, but that of the terete cylin- 

 draceous body quite constant. Monoecious flowers have been met with. 



Var. microcarpa. Fruit (seemingly full grown but seedless) remarkably small, 

 half to two thirds inch long. — F. albicans, Buckley in Proc. Acad. Philad. 1862, partly. F. 

 Curtissii, Vasey, Cat. Trees U. S. 20. — Eufaula, Alabama (Curtiss), &c. 



Var. Texensis. Low tree, glabrous throughout : leaflets mostly 5, slender-petiolu- 

 late, from ovate to broadly oval, 1^ to 2 inches long, either rounded at apex or slightly 

 acuminate : fruit small, two-thirds to barely an inch long, the wing hardly double the 

 length of the body. — F. albicans, Buckley, 1. c, in part. F: pistacice/olia, E. Hall, List. PI. 

 Tex. no. 527. F. coriacea, Watson, 1. c, as to pi. Bigelow, " Devil's Run Canon," Texas 

 (not "Arizona"), a form with remarkably long-petiolulate leaves of firmer textm-e, with- 

 out flowers or fruit. — Texas, on rocky hills, from Austin to Devil's River, near the Rio 

 Grande. Perhaps a distinct species. 



= = Body of the fruit more slender, tapering gradually from summit to base, more or less mar- 

 gined upward by the decurrent wing. 



F. pubescens, Lam. (Red Ash.) Tree of middle or large size: inner face of the 

 outer bark of the branches red or cinnamon-color when fresh : j'oung parts velvety- 

 pubescent, commonly permanently so : leaflets as of the preceding, or else longer and 

 narrower, the lower face and the petioles more tomentose : fruit commonly Ii to 2 inches 

 long ; its body more than half (or even little less than) the length of the linear or spatulate 

 wing. — Diet. ii. 548 ; Walt. Car. 254; Muhl. in N. Schrift. Berl. 1. c. ; Gray, Man. ed. 5,

 Florida ; rare \vest of Ohio. 



F. viridis, Michx. f . (Green Ash.) Small or middle-sized tree, glabrous : leaflets 

 5 to 9, bright green both sides, or barely pale beneath, from oblong-lanceolate to ovate, 

 mostly acuminate and sparsely and sharply serrate or denticulate (2 to 4 inches long) : 

 fruit nearly as in the preceding or with a rather more decurrent wing (from 9 to 18 lines long).

 and Arizona ? Pale-leaved forms, with some pubescence on the veins of the leaflets be- 

 neath, pass into the preceding. 



Var. Berlandieriana. Leaflets 3 to 5, with a more cuneate base : wing of the fruit 

 rather wider and more decurrent on the body. — F. Berlandieriana, DC. Prodr. viii. 278. 

 F. trialata, Buckley, 1. c, a state with 3-winged samara. — Texas. (Cuba?)

F. platycarpa, Michx. (Water Ash.) Tree of middle size, glabrous or pubescent : 

 branchlets terete : leaflets 5 to 7, ovate or oblong, acuminate, sharply serrate or entire, 

 conspicuously petiolulate : fruit elliptical, obovate, or spatulate (one or two inches long), 

 contracted below into a stalk-like base, each face with an impressed midnerve, not rarely

F. quadrangulata, Michx. (Blue Ash.) Large timber-tree, the inner bark yielding a 

 blue color to water, glabrous : branchlets square : leaflets 7 to 9, ovate-oblong to lanceolate,
