EXPLANATION OF PLATE V 



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

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

 termiual, crowded, spiral, elongated, amplexicaulis, acuminate, bordered with spiuose 

 teeth. Fruit sorose, peduncled, axillary, large, round, woody, composed of a great num- 

 ber of small pericarps of an hexagonal figure. The name Pandanus is from the Malay 

 word pa/idanff. Tlie common name is given from the direction of the grain of the bark, 

 which runs spirally. 



Fig. 2. Rm/opiiORA mnngle.f 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 heail of the tree ; the other aphyllous, stolonif- 

 erous, and inclining downwards, at length taking root and producing new slioots which 

 'become perfect plants. Branches opposite. Leaves opposite. Seeds germinating in the 

 fruit still suspended from the branches, and producing clavate radicles twelve or fourteen 

 Indies in length ; these, detaching themselves from the cotyledon which remains en- 

 closed in the pericarp, fall, and planting tliemselves in the earth, develop a new trunk 

 and branches, a, shows a shoot germinating. 



Fig. 3. Bromelia ananas.X Pineapi)le. An herbaceous, perennial plant, four feet 

 high ; it is a native of South America and the West Indies. Leaves radical, coriaceous, 

 channelled, ensiform, long, denticulate. Teetli spinose. Scape short. Sorose, ovate, 

 succulent, surmounted with a crown of leaves. This plant belongs to Hexandria 

 Monogynia. 



Fig. 4. THEoriiRASTA americana. (Family of the ApocinecB.)^ Shrub of South 

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

 elongated, obcrenulate, denticulate. Fruit spherical. 



* Belonging to the family Pandanea; of Brown and De Candolle ; somewhat allied to Typha3 in its* 

 fructification, and to the Palms in its arborescent stem. 



t Tlie Mangrove tribe, or RiiizoplioreaB oT Brown and De Candolle; described as "natives of the 

 shores of the tropics, where they root in tiie mud, and form a dense thicket to the verjje of the ocean." 



1 or the family Bromeiiacew, or Pineapple tribe ; Lindley says, "the habit of the Bronieliacea; is pe- 

 culiar: they are hard, dry-leaved plants, haTJng a calyx, the rigidity of which is strongly contrasted 

 with the delicnte texture ot the petals." 



§ Lindley follows Brown in placing this in the order Myrsineaj. He considers it as nea-ly related to 

 PrimuiaceaB through some of the genera of that order, and to Sapoteae through the genus .lacquinia.
