' EXPLANATION OF PLATE V. 
Fig. 1 . Pandanus.* Screw-pine. Dioecious tree of South America, 24 feet in 
height. Fertile plant. Slype cylindric, rectilinear, vertical, branches at the summit. 
Leaves terminal, crowded, spiral, elongated, amplexicaulis, acuminate, bordered 
with spinose teeth. Fruit sorose, peduncled, axillary, large, round, woody, composed 
of a great number of small pericarps of an hexagonal figure. The name Pandanus is 
from the Malay word, pandang. The common name is given from the direction of 
the grain of the bark, which runs spirally. 
Fig. 2. Rhizophora mangle .t A low tree of South America, which grows in salt 
marshes, and at the mouths of rivers near the sea. It puts forth two kinds of branches, 
the one bearing leaves, and forming the head of the tree; the other aphyllous, stolo- 
niferous, and inclining downwards, at length taking root and producing new shoots 
which become perfect plants. Branches opposite. Leaves opposite. Seeds germi¬ 
nating in the fruit still suspended from the branches, and producing clavate radicles 
twelve or fourteen inches in length; these, detaching themselves from the cotyledon 
which remains enclosed in the pericarp, fall, and planting themselves in the earth, de¬ 
velop a new trunk and branches, a, shows a shoot germinating. 
Fig. 3. Bromelia ananas.t Pineapple. An herbaceous, perennial plant, 4 feet 
high; it is a native of South America and the West Indies. Leaves radical, coria¬ 
ceous, channelled, ensiform, long, denticulate. Teeth spinose. Scape short. Sorose, 
ovate, succulent, surmounted with a crown of leaves. This plant belongs to Hexarv* 
dria Monogynia. 
Fig. 4. Theophrasta americana. (Family of the Apocinece.)% Shrub of South 
America, four feet high. Trunk very simple, spinose. Leaves crowning, verticillate, 
elongated, obcrenulate, denticulate. Fruit spherical. 
* Belonging to the family Pandancae ot Brown and De Candolle ; somewhat allied to Typhae in its fructifi¬ 
cation, and to the Palms in its arborescent stem. 
t The Mangrove tribe, or Rhizophorese of Brown and De Candolle ; described as “ natives of the shores of 
the tropics, where they root in the mud, and form a dense thicket to the verge of the ocean.” 
t Of the family Bromeliaceae, or Pineapple tribe : Lindley says, “ the habit of the Bromeliacete is pecu¬ 
liar: they are hard, dry-leaved plants, having a calyx, the rigidity of which is strongly contrasted with the 
delicate texture of the petals.” . 
§ Lindley follows Brown in placing this in the order Myrsmeae. He considers it as nearly related t© Pri- 
mulaceae through some of thq. genera of that order, and to Sapotcae through the genus Jacquinia.
