Since our notes, No. 3 on Cuba, were printed, we have received the following letter from Havana, confirming the facts connected with the curious plant described as embracing the Bishop's house and the Ceiba-trees. It will be read with interest: -

Havana, June, 1867

"John Jay Smith, Esq. - Dear Sir: The plants which envelop the Ceiba, Palms, and, in fact, any tree which has the misfortune of coming in contact with it, are not a vine. The most common is the Jaquey, Pious Indica occidentalis; the other is the Clusia rosea et alba, called here Copey. Both are handsome trees. The seeds are deposited by birds, I suppose, on the bare rocks, or in the hollow of trees. There they gemmate at first as humble parasites. Soon after, they send out a smooth, thin root, which lengthens sometimes as much as sixty or eighty yards, until it reaches the ground; there it takes root; another and another is soon after sent out, encircling the tree as with a small twine of a few lines dia-meter. They keep growing on in thickness until the unfortunate tree is smothered. Bach of these filaments or twiny roots unite together, and form of itself magnificent trees, the heart of which is the mother tree which first lent it its support, and gave it food. The Jaquey is often seen forming trees of six or eight yards diameter at the bottom or lowest part. It is a most beautiful tree, and gives a delightful shade.

The Juice is used as glue, to catch birds, The wood has no application.

"The Copey, er Clusia, is not so large. Its habits are nearly the same. The roots or filaments that shoot downwards to the earth, aa thin as they are, can bear the weight of three or four persons. Its large and beautiful flower, its singular shaped fruit, its thick and shiny leaves, make it a very handsome tree. The juice is a gum resin (which it yields abundantly), at first white, but soon yellow. It may be used as glue for book-binding, as the insects never attack it.

"I now hand you a painting of the flower of the Carolinea-tree, a Pachira of the Bom-b&ceffl family.

"Any information you may desire on the natural history or botany of Cuba, I shall be glad to transmit. I remain, respectfully, dear sir, your most obedient servant, Franclsco A. Sauvalle".
