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

 valuable timber-tree : fruit variable in size and shape of wmg, 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 

 Cwtissii, Vasey, Cat. Trees U. S. 20. — Eufaula, Alabama {Curtiss), &c. 



Var. Texensis. Low tree, glabrous tliroughout : 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. pistacimfolia, B. Hall, List. PI.

 Grande. Perhaps a distinct species. 



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

 gmed upward by the decurrent wing. 



P. 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: young 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 1^ to 2 inches 

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

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

F. viridis, Michx. f. (Green Ash.) SmaU 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).

Var. Berlaildieriana. 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?)

 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),
