Borassus flabelliformis is a grand tropical palm from southern Asia, and the East Indian Archipelago. The Palmyra, as it is called, is dioecious, has enormous, fan-shaped leaves and bears bunches of flowers and fruit from the axils of the leaves. I do not know that it has been cultivated in Florida but it should be tried in the warmer parts of the state.
Chamaerops Humilis from southern Europe and northern Africa is a beautiful, very hardy palm. The leaves are divided into a great number of segments and their under surfaces are somewhat silvery. The compact heads of yellow flowers are quite attractive; the tree is vigorous and healthy here, and it ought to be generally cultivated. It is quite variable and the variations have received specific names. There is a larger form, possibly a species, which grows in northern Africa, called C. macrocarpa, which is also fine. They will grow on pine land and in exposed situations.
C. cerifera is the Wax Palm of Brazil, the young leaves being covered with wax. It is a handsome palm and should be tried in Florida. There are several fine species in Cuba.
A genus of noble palms with immense leaves from southeastern Asia which contains the famous Talipot Palm (C. umbraculifera). The leaves are said to be sometimes twenty feet across and the enormous panicles of white flowers may reach an equal length. The trees of this genus are slow growing when young and when they blossom they die. I have tried C. um-braculifera, C. megapoda, C. gebanga and C. elata and all have flailed. I understand that they have not succeeded in Florida.
A group of palms from Lower California and Mexico, containing three species, - I have had no success whatever with any of them.
Tropical palms from Equatorial Africa with very firm leaves, the rachides armed with strong spines. The trunks branch in old trees and the nut is covered with an edible pulp, hence the name Gingerbread Palm. I have a very fine specimen of H. schatan in my grounds but up to date it has not produced anything in the cookery line.
The species included in this group have generally been called Sabal. In Inodes the midrib of the leaf is bent backwards while in Sabal the leaf is flat. This is a group of American palms designated as the palmettos, rather slow growing when young but quite vigorous at maturity. They all succeed admirably in Florida and are among our finest garden ornaments. The genus is represented in Florida by I. palmetto the common cabbage tree, and a dwarf species with an S-shaped stem which is all buried in the ground; the latter, I. megacarpa, living on the shores of Biscayne Bay and for some distance northward. I. caerulescens, I. mauritiaeformis, I. ghiesbreghti, I. umbraculifera and J. princeps are beautiful. When on pine land it is a great help to give them liberal dressings of muck. Most of the species will probably prove hardy half way up the peninsula.
A magnificent group of palms from Mauritius and neighboring islands. Their leaves are among the most majestic of any of the family, either in a young state or when mature, all being more or less highly colored. They are tender but may be grown in places exposed to the sea, even where they are sometimes submerged. Specimens of L. loddigesi and L. commersoni at Cape Florida were completely covered with water for several hours some years ago during a hurricane but were uninjured. The so-called Latania borbonica is a Livistona.
Licuala Peltata, Elegans, Runiphi, Grandis And Horrida have all been in my collection but without exception have totally failed, and other growers in the state report a similar experience. They are beautiful palms, generally of dwarf size, which grow in the hot, steamy forests of the Oriental Tropics.
Livistona is a fine genus of palms from the same general region as Licuala, but I have had much better success with it. L. chinensis, commonly called Latania borbonica, is a beautiful, slow growing species, quite hardy. L. altissima, L. hoogendorpi, L. subglobosa, L. jenkinsiana, L. olivaeformis and L. mariae have all done well with me. L. rotundifolia is a charming species. All except the first are probably tender.
Lodoicea Seychellarum is the celebrated Coco de Mer, or Double Coconut, from the Seychelles. It is a wonderful tree with a trunk a foot in diameter and a hundred feet high; the fan-shaped leaves are twelve feet long and twenty wide. It does not bear fruit until it is thirty years old; the nuts weigh forty pounds each and require ten years to ripen. The base of the tree is rounded and fits into a natural bowl which is filled with holes through which the roots pass. This bowl is a part of the tree but is not attached to it and it has been found in a good state of preservation sixty years after the tree has died. The nuts require a long time to germinate but they have been sprouted and are growing at Washington. They should be tried in lower Florida.
