During the months of October and November last, Dr. A. W. Chapman of Apalachicola, Fla., made a journey along the western coast of Florida, examining the Keys and running up several rivers into the interior. The journey was made by schooner for the purpose of obtaining specimens of the trees of that region, for the display of forest trees which is to be made by the Department of Agriculture at the approaching Centennial.

It is pretty well known that the vegetation of Southern Florida is of the West Indian type, and is not found in any other portion of the United States. What knowledge we have of that region is recorded principally in Dr. Chapman's Flora of the Southern States which was prepared some years ago, and as that region has been little visited by botanists, our information has been little extended since. I made out a list from Dr. Chapman's Flora, of such plants as were recorded as trees, amounting to about forty species.

The result of Dr. Chapman's investigation will best be stated by quoting from his Report. He says:"The number collected exceeds your estimate by ten species and falls short of my own by the same number. I believe I obtained all the native trees known down there except Simarnba, and perhaps Calyptranthus, if it is a tree. I found several trees which I supposed to be shrubs and vice versa. I made a thorough exploration of the whole western coast from An-clote Keys to Cape. Sable, wherever we could find smooth water for safe anchorage. At Charlotte Harbor I diverged from the coast and ascended Caloosahatchie river, in order to get such woods as do not grow in the influence of salt air. This was really the most interesting part of the route. Gigantic Acrostichums ten feet high covering acres, Epiphytes loading the trees, and the entire vegetation tropical. A peculiarity of these tropical trees is that for miles they occur to you as mere shrubs, when at some other locality you find them lofty trees. I was much disappointed in the size of most of the forest growth in that region. On the Keys you can scarcely anywhere find a large, (or rather a tall) tree. Some of these were large enough at the base, but we generally found such hollow, and of some we never did find a sound one.

You will be disappointed, as I was, to find the growth so small. I do not remember to have seen a tree, during the trip, two feet in diameter, with the exception of the live oak, and on the Keys none of them get to be more than thirty or forty feet high. The Mahogany is not found in Florida, and should be erased from the Flora, My authority for introducing it was a pod picked up on the beach by Dr. Leitner. Hibiscus tiliaceus was not seen by me, and I think Dr. Blodgett must have got it from cultivation. In Jamaica it is a shrub twelve to fifteen feet high. Terminalia is not a native, and is, I believe, local along the St. John's or near St Augustine. The others mentioned I did not meet with on any of the Keys I visited. Whether they become trees I cannot say, for I- forget the sources of my information regarding them when writing my book. It was of course impossible to visit all of the hundreds of Keys along the reefs, and it is probable that these omissions may occur on more westwardly ones than those I visited."

I append Dr. Chapman's list of trees obtained (modifying the arrangement) believing that it will be found very interesting.

Anona? (Custard Apple). No flowers or fruit, fifteen to twenty feet high. The fruit is said to be egg-shaped, one and a half inches in diameter, and eatable when fully ripe.

Capparis Jamaiccnsis (Caper tree). A low tree.

Canella alba.

Guaiacum sanctum (Lignum Vitae). Only found, if I am rightly informed, on the "Lignum Vitae Keys," and quite rare there.

Xanthoxylum Pterota {------). 15 to 20 feet high.

Bursera gummifcra (Gumbo Limbo, Gummer Limmer). The largest of South Florida trees abounding in gum.

Amyris Floridana (Torch-wood). Mostly shrubby.

Ximenia Americana (Hog Plum). 2 to 20 feet high.

Schiefferia frutescens? (Crab-wood). A small tree.

Sapindus (White-wood). This is scarcely the tree of the Southern States and of my Flora; I suspect it is S. saponaria.

Hypelate paniculata (Madeira-wood). This wood is very like Mahogany and is highly valued. It is not abundant and was only found on Metacumba Keys.

Rhus Metopium (--------). 20 to 30 feet high.

It is very poisonous and we all got peppered by it.

Piscidia Erythrina (Dog-wood). A rather large tree.

Pithecolobium Unguis-Cati. Rarely a small tree.

Rhizophora Mangle (Red Mangrove). Commonly a low spreading tree. On the Thousand Islands it attains its largest size, forty to sixty feet, All the low Keys are formed by this tree.

Conocarpus erecta (White Button-wood). It comprises almost the only fuel used in Southern Florida, and extends north as far as Anclote Keys.

Laguncularia racemosa'(Black Button-wood). A small tree everywhere, or a mere shrub except among the thousand Islands and north of Cape Sable, where it forms a large tree.

Eugenia buxifolia (Iron-wood). 25 to 30 feet high.

Eugenia monticola {--------). South Florida, about 20 feet high.

Eugenia--------.

Eugenia --------, near dichotoma, but probably distinct. This was only seen at Caximbus Bay, and was called " Naked Wood."

Eugenia--------(Stopper-wood). A small tree, in fr.

Gueitarda Blodgetti. Mostly a shrub. Randia clusisefolia (Seven year's Apple), with fl. and fr.

Sideroxylon pallidum (Mastic). A middle-sized tree.

Sideroxylon pallidum, var. spheerocarpum. A small tree.

Sideroxylon--------. A large tree.

Chrysophyllum microphyllum. Six to twenty feet high.

Mimusops Sieberi (--------). A large tree. We found the trunk invariably hollow.

Bumelia parvifolia (--------). A shrub or small tree.

Jaquinia armillaris. A rather small tree with most curiously grained wood.

Myrsine Floridana. Mostly a shrub, rarely a small tree.

Ardisia Pickeringii. Mostly a shrub, but on the Keys a small tree.

Citharexylon villosum (Fiddle-wood). Rarely a small tree.

Avicennia oblongifolia (Black Mangrove). Only a tree among the Thousand Islands.

Avicennia tomentosa (Black Mangrove). At Cedar Keys only.

Pisonia obtusata (--------). With male flowers.

Coccoloba Floridana. 20 to 30 feet high. In fruit.

Coccoloba uvifera (Sea-side Grape). In fruit.

Persea Catesbxi (--------). No flowers or fruit.

Drypetes crocea (--------). A small tree.

Ficus aurea (Wild Fig). A large tree, full of milky juice. It is also called Gum Tree, and the juice forms a kind of India Rubber.

Ficus--------. Perhaps the same as the preceding.

. . . . (Silver Palmetto or Silver Cabbage Tree.) The berries are white, but in the absence of flowers the genus is doubtful. It attains a height of 30 to 40 feet. It occurs first at Cape Romano, and is found sparingly on the mainland southward. It is more common on the Keys, but I never heard of it before.

Yucca aloifolia? (--------). I found this from Manitee southward, 15 to 25 feet high.

Pinus Clausa, N. sp. At Apalachicola. Dr. Engelmann is doubtful. Perhaps it may be a variety of P. inops.
