wahoo elm is found only in the lower part of Virginia, in themaritime districts of the Carolinas and Georgia, in WestTennessee, and in some parts of Kentucky . It is generallyfound on the banks of rivers, and in the great swamps en- iclosed in the pine barrens. The wood is fine-grained, more ccompact, heavier, and stronger than that of U. americana.The heart-wood is of a dull chocolate colour, and alwaysbears a great proportion to the sap-wood. At Charleston ,and some other parts of the southern states, it is used forthe naves of coach wheels ; but Michaux says that it is not

appropriated to any other use. There are small plants inMessrs. Loddiges’s collection, which, from the leaves, mightbe taken for those of U. ( c.) suberosa ; and the engraving

in Michaux, from which fig. 1248. is reduced to our usualscale, closely resembles the young shoots and leaves of that tree of U. (c.)suberosa in the Horticultural Society’s Garden, of which a plate is given inour last Volume.

App. i. Doubtful Sorts ofXJ'lmus.

This genus, as observed by Professor Lindley (Synops., p. 227.), is in such a state of confusion, that itis impossible to determine what plants are meant by various names extant in botanical works. U. pu-bcscens Walt, and U. fruticbsa Willd. are of this description. In p. 174., U. integrifblia and U. virghiaare mentioned as Himalayan species, probably hardy or half-hardy. In Royle’s Illust., p. 339., U.lancifdlia, U. erdsa, which resembles U. efftisa, U. Icsvigata, and U. virgata, are mentioned as nativesof the Himalayas and other parts of India, and some of them of China . A plant named V. canadensis,in the Horticultural Society’s Garden, has a smooth bark, like U. montana, and appears to be nothingmore than that species. The Wormley Grange, or Byford, elm, and the black elm of Ireland , aresaid by Dr. Lindley to be probably other species to add to the British flora. Sir J. E. Smith considersthe Hertfordshire elm as U. montdna; but Dr. Lindley says that it “ is probably a variety of U cam-ptetris.” Notwithstanding the utmost attention that we have been able to give to this subject, andthe communication of specimens from all parts of the country, we have by no means been able todraw up this article in a manner perfectly satisfactory to ourselves. Specimens, except in caseswhere they have been gathered from trees by ourselves, and, therefore, serve to remind us of the ge-neral appearance and habit of the tree whence they have been taken, we have found in this, as in manyother cases, to be of comparatively little use. The genus, as Dr. Lindley has observed, must bestudied during a period of several years, from living plants. An ulmarium, though it would notexhibit so much grandeur as a pinetum, so much beauty as an erieetum, nor so much blossom inearly spring as a salictum, would be incomparably more useful j provided proper space were allowedto admit of every tree attaining its natural size and shape, and that, after ten or twelve years, aspecimen of every tree were cut down, and the wood examined.
