EXPLANATION OF PLATE V. 



Fig. 1. Pandanus.* Screw-pine. Dioscious tree of South America, 24 feet in 

 Height. Fertile plant. Stype cylindric, rectilinear, vertical, branches at the summit. 

 Leaves terminal, crowdecl, spiral, elonp;ated, 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

Fig. 2. RmzoPHORA mangle.i 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 mchning 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 Hexan- 

 dria Monogynia. 



Fig. 4. Theophrasta americana. (Family of the .4poei7zecE.)§ Shrub of South 

 America, four feet high. Trunk very simple, spinose. Leaves crowning, verticillate, 

 elongated, obcrenulate, denticulate. Fruit spherical. 



* Belonging to the family PandanoEE of Brown and De CandoIIe ; somewliat allied to Typhae in its fructifi- 

 cation, and to the Palms in its arborescent stem. 



t The Manffrove trilje, or Rhiznphoreae of Brown and De CandoIIe ; described as " natives of the shores of 

 the tropics, where they root in the mud, and form a dense tliioket to the verge of the ocean." 



I Of the family BromeliaceEB, or Pineapple tribe ; Lindley says, " ihe 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 Myrsinese. He considers it as nearly related to Pri- 

 mulaceae through some of th^ genera of that order, and to Sapotcae through the genus Jacquinia.
