1st Palmes Palms. These from their noble growth were called by 
Linnaeus Principes, or Princes of the Vegetable World. The size and 
appearance of some of these noble trees,maybe partly conceived by 
imagining a stem * growing straight, and branching to the height of 
100 or 150 feet, and spreading from the top of this vegetable column, 
thirty or forty vast leaves, of fourteen feet in diameter! This class 
of plants differ exceedingly in the principle of their growth, from 
the timber and other trees with which we are familiar, resembling 
more the bamboos or grasses, being hollow at the commencement of 
their attaining full size, and afterwards filling up in the inside towards 
the centre, instead of receiving successive depositions, layer on layer 
on the outside, as is the case with all timber trees. On account of 
this peculiarity. Palms and other plants of like formation, are called 
endogenous , or inside growers, whilst the others are denominated 
exogenous or outside growers. Endogenous plants continue to fill up 
the hollow stem until there is no more room for them to grow, and as 
in the case of the Talipot Palm, and some others, they flower and die. 
* The stems of Palms have, by some writers, been considered as an extended 
cormus, and not a true stem, but this seems an extravagant application of the 
term ; or rather an application which reduces the signification of the term to no¬ 
thing. A cormus is a depressed subterranean stem of a particular kind: the 
trunk of a Palm is, as far as its external character is concerned, as much a stem 
as that of an Oak.—D r. Lindley Int. Bot.page 55.
