to parietal placentas equalling the styles in number. Capsule membranous, 
loculicidally 3-5-valved; seeds numerous, albuminous ; embryo straight, 
axile. 
A small family, comprising 6 genera and about 120 species, distributed over the 
whole world with the exception of Polynesia, but most abundant in. Australia. The 
whole of the species capture insects, usually by means of glandular viscid and irritable 
hairs; but in some cases, as the well-known Venus’s fly-trap (Dionaea muscipula) by 
rapidly closing laminae, which shut the insects as it were In a box. or a full account 
reference should be made to Mr. Darwin’s well-known book on “ Insectivorous Piants.” 
The single New Zealand genus is the largest in the family, and has an almost world- 
wide distribution.
