long and less than 1 mm. wide, and tlie shape of the leaves \vliicli are often 

 rounded at apex and more symmetrical at base seem to distinguish suffi- 

 ciently the soutliern plant from 77. virginiana. From IL.veriadis it differs in 

 the yellow color of the inner surface of the calyx, and in the tubercles on the 

 leaves which are green and not pale or glaucous below, and I am inclined to 

 consider the plant of the Gulf States a species and to take up for it Pursh's 

 name although it is an unfortunate one for the leaves are usually smaller 

 than those of 77. virginiana and they are rarely if ever " suborbicular." 



Hamamelis macrophylla Pursh, Fl. Am. Sept. i. IIG, 18M. — Elliott, 

 Sketch, I. S'iU (1821). — Hamamelis virginiana /3. macrophylla Nuttall, 

 Gen. I. 107, 1818. — Hamamelis virginiana of many authors, not L. 



Leaves oblong-ol>ovatc or occasionally broad-elliptic, rounded, acute or 

 rarely acuminate at apex, cuneate, rounded or cordate at the narrow slightly 

 unsvnunctrical base, crcnalely lobulate above the middle with small 

 rounded lobes, covered when they unfold with short stellate hairs more 

 abundant on the lower than on the upper surface, at nuiturity dark greeu 

 above, lighter green below, and roughened by the persistent tubercle-like 

 bases of the stellate hairs, 8-13 cm. long, and 5-8 cm. wi<l(N with a slender 

 midrib and five or six pairs of primary veins; petioles slender, pubescent, 

 1.5-2 cm. in length. Flowers oi)ening in December, January and February; 

 caljTC yellow often slightly streaked with red on the inner surface. Fruit 

 ripening in the autunm, about 1.2 cm, long; seeds acute, dark chestnut- 

 brown or nearly black. 



A tree often 10-15 m. high, producing stoloniferous shoots round the tall 

 trunk up to 15 cm. in diameter, spreading branches, and branchlets rusty 

 tomentose during their first year, becoming glabrous or nearly glabrous in 

 their second season.
