Identification. Lin. Sp., 2. p.'755.; Willd. Arb., p. 230.; Dec. Prod., 1. p. 80. ; Don’s Mill, 1. p. 82. 
Synonymes. M. fragrans Salisb.; Swamp Sassafras, Beaver-wood, white Bay, small, Magnolia, 
Swamp Magnolia; Magnolie glauque, Arbre de Castor, Fr. ; grauer Bieberbaum, Ger. 
Derivations. It isnamed Swamp Sassafras on account of its growing in boggy places, and resembling 
in qualities the LaGrus Sdssafras ; and Beaver-wood, because the root is eaten as a great dainty by the 
beavers, and these animals are caught by means of it. It also grows inthe swamps, which they in- 
habit ; and Michaux tells us that itjis felled by them for constructing theirdens and houses, in pre- 
ference to any other tree, on account of the softness of the wood.

Varieties. The only aboriginal varieties, if varieties they can be called (for 
they appear to be only variations), are, that which retains its leaves during 
the greater part of the year, which appears to depend upon the moisture of 
the soil in which the plant grows, and which is called, in the nurseries, M. 
glafiica sempervirens ; that which assumes more of the tree character, and 
is called M. glatca arborea; and a third, noticed by Pursh, which has the 
under surface of the leaves somewhat silvery, and is accordingly named M. 
g. argéntea. 
¥ M. glaiica 2 Thompsoniana Thomp. Thompson’s glaucous-leaved Mag- 
nolia, M. glatca var. a major (Bot. Mag., new edit. p. 36.) —This is 
a supposed hybrid between M. glaica and M. tripétala; though it 
may possibly be only a long-leaved arboreous variety of M. glatica. 
It was noticed in a pot of seedlings by Mr. Thompson, in his nursery 
at Mile End, and by him kept distinct, and propagated under the 
above name. We should say that it was only a variety or race of 
the aboriginal species, enlarged in all its parts. 
* M. glaica 3 longifolia Hort., the long-leaved glaucous Magnolia, is a 
variety produced, as it is supposed, between M. tripétala and M. 
glatica. It was originated in Belgium, and imported into this country 
by Mr. Knight of the Exotic Nursery, King’s Road, Chelsea. It is 
in appearance intermediate between the two species; and seems to 
correspond with the M. longifolia of Pursh. The leaves are elliptical, 
acute at both ends, longer than those of M. glatica Thompsoniana, 
and resembling those of M. tripétala, but thicker, smaller, and glaucous 
underneath. It is a very handsome tree, and, supposing it to be that 
‘described by Pursh, it is found in Florida and Georgia. The flowers 
are sweet-scented, and resemble those of M. glaica Thompsonidza, 
but are smaller. 
Other Varieties. M.glatica Gordoniina, and M. glaica Burchelliana are 
_ variations or varieties, the names of which are found in some nurserymen’s 
catalogues ; the former having been raised by Mr. Gordon, at Mile End, and 
the other by Mr. Burchell, at Fulham: but they do not appear to us at all 
distinct. There are also semi-double and double-flowered varieties in some 
nurserymen’s catalogues, but the only distinct varieties are M. glatica 
Thompsonidna, and M. glaica longifolia. 
Description. A low tree, nearly evergreen, with slender stem, covered with 
a smooth whitish bark. The wood is white and spongy. The leaves are 
smooth, of a bluish green on their upper surface, and whitish or glaucous and 
a little hairy underneath. The flowers are produced in May or June, at the 
extremity of the last year’s shoots.- They have six concaye white petals, and
