method of dehiscence is as follows:—The capsule splits at the 
base along all its five sutures at once and the several elastic 
portions roll up towards the apex, the motion being so rapid that 
when the limit of the elastic half of the capsule has been reached 
the membranous portion is torn to pieces and the seeds are thrown 
out. It wilkbe noticed that here there is only one motion 
It would appear probable that in those species in which the bag 
is at the base and the elastic portion is at the apex it would be 
found that the action would be similar except for the fact that 
the sutures would all split first at the apex and the several por- 
tions would coil inwards and downwards instead of outwards and 
upwards, but no actual ‘species of this kind have been collected in 
Burma by the writer although, no deubt, they are common. To 
such an extent is the distribution of the ‘seeds dependent o1 on the 
tearing to pieces of the membranous bag by the force of the elastic 
half, that if the capsule is held at the juncture of these two tissues 
till the force of the elastic portion is expended and then released, 
it will be ‘found that the bag ee the seeds’ has lost all 
power of splitting up and ejecting them
