PANDANEZX. 
General Remarks. 
1. Pandanee approach to Palme, through Nipa, by those 
species in which the pistilla are disposed in phalanges, 
These pistilla however cannot be considered as representing, 
(like those of Nipa) a simple fruit, or syncarpous pistillum, as 
they are in two series, and the number of neither of these is 
precisely definite. 
In appearance there is a marked resemblance to those of 
Nipa, but the ventral suture is well developed, and the stig- 
mata have more of the ordinary appearance. The phalangeal 
disposition is remarkable from not being accidental: it obvi- 
ously indicates each phalange as constituting a distinct fruit 
of two series of carpells looking inwards towards their own 
axis, the outer series varying in number from З to 5, but ge- 
nerally 4 or 5, the inner, almost always having 2 absent. 
We may therefore certainly expect to find forms in which 
two series may be perfectly distinct, or even increased in num- 
ber, and if the plants be Moncecious, each of the partial axes, 
may have a male coma. 
ontrasted with Palmze, the size of the placentz is curious, 
and is the more remarkable from their only producing one 
ovulum, and that near the base.
