Peovince, ENDOGENS, 



Or Monocottlbdons. PhEenogamous Plants having a stem 

 without the distinction of bark, wood and pith, composed of 

 thread-like htmdles of trachenchyma imbedded irregularly in 

 the general cellular mass, the newest interior, not forming layers 

 in growth. Leaves mostly parallel-veined. Flowers very gener- 

 .ally 3-merous. Embryo with one cotyledon, rarely with 2 alter- 

 nate and unequal. 



Class III. PETALIFEK^. Plants of the endogenous struc- 

 ture, the flowers normal and complete with a whorled pe- 

 rianth, or the perianth wanting — in either case destitute of 

 glumes.

Trees or shrubs chiefly with unbranched trunks growing by the terminal bud. 

 Leaves large, plaited, on sheathing petioles, collected in one terminal cluster. Flow- 

 ers perfect or polygamous, on a branching spadix bursting from a spathe. Perianlh 

 double, 3-merous, hexandrous, ovaries (and styles) 3, distinct or commonly united 

 into 1, each 1-ovuled. Fruit fleshy, 1 — 3-seeded, embryo minute, superficially 

 imbedded in albumen. Kg. 47, d, e. 



Genera 73, specien 500 ? of noble aspect and most interesting attributes. They are chiefly 

 tropical, a few advancing into the wai-mer parts of the Temperate Zone. 



The pi-operties and uses of tlie Pahns ave of the highest Iraportanco and variety. JFrom tha 

 drupes of several African P.ilms, and from the Cocoa Nut, oil is obtained. Other species secrete 

 «)ff« from, tllcJir leaves. Starch is obtained abundantly from the Sago Palm (Sagus Rumphii) 

 and maoy Other species. Even suffar^ and alcoholic liquors, .ire made froiji the juice of the 

 unopened spathe of Sftguerus saceharifer, Mauritia vinifer, &c. The bud of the Cabbage Palm 

 ^Areca oler.acfa) is boiled and eaten as a vegetable. Among the/ruiiBf are enumerated the date^ 

 Irom Phoinis dactylifera, and the cocoa-nut, from Attalea funifera. &c.
