The dry stove seems to suit it, for there it produces its 
rich orange flowers in great perfection, and retains them in 
all their freshness and beauty for several weeks. 
We do not understand upon what principle this genus is 
referred to the Linnean Hexandria Monogynia, instead of 
Trigyuia, for it unquestionably has 3 distinct styles ; unless 
it is to be considered a new case of the necessity of under- 
standing the natural affinities of plants in order to use the 
sexual system. 
Few persons, when they look at the leaves of a plant, 
ever think of the curious internal mechanism by which all 
its vital actions are put and maintained in motion ; and yet 
there is not in the whole range of the creation a. more 
singular object than a leaf, nor one whose structure is a 
more admirable instance of design and forethought. The 
internal anatomy in this species is highly curious and very 
easily examined. It consists as usual of a quantity of cellular 
matter enclosed in a cuticle, but the arrangement of the 
parts, which is most uncommon, is probably connected with 
the habits of life of the species in its native wildernesses. 
The cuticle is hard and composed on the upper surface of 
three, and on the lower of five layers of extremely minute 
compact cubical cells. The leaf itself is plane above and 
convex below; corresponding with the convexity is a 
stratum of equal thickness of dodecahedral cells, which are 
green, and pierced towards their upper side by the parallel 
veins of the leaf; above this structure is a very thick plano- 
convex bed of hard prismatical cells, which are planted nearly 
perpendicularly below the cuticle; so that when the section 
of the leaf is viewed by the naked eye it appears, as is
