Fig. 1. Pandanus * Screw-pine. Dioecious tree of South America, 24 foei tn 
neignu Fertile plant. Sivpe cylindric, rectilinear, vertical, branches at the suinmii. 
Leaves terminal, crowded, spiral, elongated, amplexicaulis, acuminate, burdered 
With spinose teeth. F'ruit sorose, peduncled, axillary, large, round, woody, composed 
cf a great number of small pericarps of an hexagonal figure. The name Pandanus is 
from the Malay word, pavdanff. The common name is given from the direction ot 
the grain of the bark, which runs spirally. 
Fig. 2. Rhizophoba manffteA 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, siolo- 
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 radiclea 
t>\elve or fourteen inches in length; these, detaching themselves from the cotyledon 
wnich 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 
h:gh; it is a native of South America and the West Indies. Leaves radical, coria- 
ceous, channelled, ensifonn, long, denticulate. Teeth spinose. Scape short. Sorose, 
ovate, succulent, surmounted with a croAm of leaves. This plant belongs to Hexan- 
drla Monogynia. 
Fig. 4. Theophrasta americana. (Family of the Apocine(B.)% Shrub of South 
America, four feet high. Trunk very simple, spinose. Leaves crowning, verticillate, 
elongated, obcrenulate, denticulate. Fruit spherical. 
* Belonginf; to the family Pandannte of Brown and De Candolle ; somewhat allied to Typha in its fructifi- 
cation, and to the Palms in its arborescent stem. 
t The Manerove tribe, or Rhizophoreae of Brown and De Candolle ; described as " natives of the shores of 
the trollies, where they root in the mud, and tbmi a dense tliicket to the verge of the ocean." 
t or the family Bromoliaceae, or Pineapple tribe : Lindley says, " the habit of the Bromeliacese is pecu- 
Kar: they are hard, dry-leaved plants, having a caljrx, the rigidity of wliich is strongly contrasted with tlia 
jelirate texture of the p«?tals. " 
$ l,indley follows Brown in placing this in t^le order MyrsinetE. lie considers it as nearly related to Pri- 
inu.Mce(D through some of tn^ genera of tiiut order, and tu riaputest tbrougii the genus Jaciiuinia.
