tose, 3' i' loug, 1^-2^' wide; seeds obovoid or triangular obovoid, more or less 

 flattened, ^' long. 



A tree, of pyramidal habit, 60-80 liigh, with a tall straight trunk occasionallj 

 40-41 in diameter, rather small spreading branches, and branchlets hoary-tomentose 

 at first, slightly tomeutose in their second year, and much roughened by the elevated

leaf-scars displaying a marginal row of conspicuous fibro-vascular bundle-scars. 

 Winter-buds pale or rusty-tomentose, the terminal I'-l^' long. Bark ^'-^' thick, 

 gray or light brown and covered with thin appressed scales, rarely more than 1' 

 long. Wood hard, heavy, creamy white, soon turning brown with exposure, hardly 

 distinguishable from the heartwood of 60-80 layers of annual growth; little used 

 except for fuel. 



Distribution. Rich moist soil on the borders of river swamps and Pine-barren 

 ponds, or rarely on high rolling hills; coast of Xorth Carolina southward to Mosquito 

 Inlet and the shores of Tampa Bay, Florida, extending across the peninsula, and 

 through the maritime portions of the other Gulf states to the valley of the Brazos 

 River, Texas, through western Louisiana to southern Arkansas, and on the bluffs 

 of the lower Mississippi River northward to the mouth of the Yazoo River; best 

 developed and often the characteristic and most conspicuous feature of the forest in 

 western Louisiana. 



Largely cultivated as an ornamental tree in all countries of temperate climate ; in 

 the eastern United States precariously hardy as far north as Philadelphia. Numer- 

 ous varieties, differing in the form of the leaf and in the duration of the flowering 

 period, have appeared in European nurseries; of these, the most distinct is the vari- 

 ety Exoniensis, Loud., with a rather fastigiate habit and broadly elliptical leaves 

 densely clothed with rusty tomentum on the lower surface, which begins to flower 

 when only a few feet high. 



2. Magnolia glauca, L. Svsreet Bay. Swamp Bay. 



Leaves oblong or oval and obtuse or somewhat oblong-lanceolate, covered when 

 they unfold with long white silky deciduous hairs, at maturity bright green, lustrous 

 and glabrous on the upper surface, minutely pubescent and pale or nearly white on 

 the lower surface, 4'-6' long, \'-^\' wide, with conspicuous midribs and primary 

 veins, falling in the north late in November and in early winter, at the south remain-
