 bescent : leaflets 7-9, ovate or oblong-lanceolate, taper-pointed, almost entire, 

 pale or more or less pubescent beneath ; fruit acute at the base, flattish and 2-edged, 

 the edges gradually dilated into the long (l^'-2') oblanceolate or linear-lanceolate, 

 icing. (F. tomentosa, Michx.) — With No. 1: rare west of the Alleghanies : a 

 smaller tree, less valuable for timber : passes by gradations into the next. 



3. P. viridis, Michx. f. (Green Ash.) Glabrous throughout ; leaflets 5 - 9, 

 ovate or oblong-lanceolate, often wedge-shaped at the base and serrate above. 

 bright green both sides ; fruit acute at the base, striate, 2-edged or margined, gradually 

 dilated into an oblanceolate or linear-spatulate wing, much as in No. 2. (F. 

 concolor, Mukl. F. juglandifolia, Wtlld., DC, and Ed. 1, but not of Lam.) — 

 Near streams, New England to Wisconsin and southward; most common west- 

 ward. — A small or middle-sized tree. ( The figure of the fruit given in Michaux's 

 Sylva evidently belongs to F. Americana.) 



* * Fruit winged all round the seed-bearing portion. 

 -t- Calyx wanting, at least in the fertile flower*, which are entirely naked! 



4. F. sambucifolia, Lam. (Black or Water Ash.) Branchlets and 

 petioles glabrous; leaflets 7-11, sessile, oblong-lanceolate, tapering to a point, 

 serrate, obtuse or rounded at the base, green and smooth both sides, when young 

 with some rusty hairs along the midrib ; fruit linear-oblong or narrowly ellipti- 

 cal, blunt at both ends. — Swamps, Penn. to Kentucky, and everywhere north- 

 ward. April, May. — Small tree; its tough wood separable into thin layers, 

 used for coarse basket-work, &c. Bruised leaves with the odor of Elder. 



•*- ■»- Calyx present, persistent at the base of the fruit. 



5. F. quadrangulata, Michx. (Blue Ash.) Branchlets square, at least 

 on vigorous shoots, glabrous ; leaflets 7-9, short-stalked, oblong-ovate or lance- 

 olate, pointed, sharply serrate, green both sides ; fruit narrowly oblong, blunt, and 

 of the same width at both ends, or slightly narrowed at the base, often notched at 

 the apex (1^' long, \' -|' wide). — Dry or moist rich woods, Ohio to Wisconsin, 

 Illinois, and Kentucky. — Tree large, with timber like No. 1. 



6. F. platyearpa, Michx. (Carolina Water-Ash.) Branchlets terete, 

 glabrous or pubescent ; leaflets 5-7, ovate or oblong, acute at both ends, short- 

 stalked ; fruit broadly winged (not rarely 3-winged), oblong (9'' wide), with a taper- 

 ing base. — Wet woods, Virginia and southward. March. 



5. FORESTIEE-A, Poir. (Adelia, Michx.) 



Flowers dioecious, crowded in catkin-like scaly buds from the axils of last 

 year's leaves, imbricated with scales. Corolla none. Calyx early deciduous, 

 of 4 minute sepals. Stamens 2-4: anthers oblong. Ovary ovate, 2-celled, 

 with 2 pendulous ovules in each cell : style slender : stigma somewhat 2-lobed. 

 Drupe small, ovoid, 1-celled, 1 -seeded. — Shrubs, with opposite and often fasci- 

 cled deciduous leaves and small flowers. Fertile peduncles short, 1 -3-flowered. 

 (Named for M. Forestier, a French physician.) 



1 . F. acuminata, Poir. Glabrous ; leaves thin, oblong-ovate or ovate- 

 lanceolate, acuminate at both ends, often serrulate; drupe oblong, usually 

 pointed. — Wet river-banks, W. Illinois and southward. April.
