culars, valvular æstivation, opposition of stamina, composi- 
tion of ovarium, structure of placentæ and reduction of the 
usual parts of an ovulum ; this being carried to its maximum 
in Loranthaceæ, the differences of albuminous seeds are non- 
adhesion of calyx in one, but this may be explained away, 
and the development of corolla, which as it is irregular, 
is of less account, 
Santalaceæ are usually supposed very nearly akin to Elæag- 
nez and other Tubiferous classes, but the affinity may not 
perhaps be so very close to Proteaceæ. Thymelez, and Eleag- 
nez have simple ovaria ;a sign of much consequence. Lindley 
places Anthobol ee among Thymelee on account of its 
superior fruit, but as it agrees otherwise with Santalaceze, it 
will probably serve to point out, that the ideas I have 
above noted are very natural. 
Choretrum is stated by Brown to have a very minute 5-par- 
tite calyx, I say from analogy that its perianth is more co- 
lored than those in which no calycule exists. Quincha- 
malium has an urceolate bractea, totally distinct from the 
ovary, and this is rightly considered by Brown as an argu- 
ment in favour of the perianth of the related orders being 
calycine. This instance I take to be most important, for it 
explains away the greater part of the anomalies, for the brac- 
tea cuculliformis of Quinchamalium is obviously akin to the 
calycule of Loranthacez, the same of Schepfia, the same 
perhaps of Olacinez. 
As Brown says it is probable that the perianth is calycine 
not corolline, because of the valvate estivation, an uncommon 
occurrence among truly petalous orders. Then he notices 
Viscum and Loranthus. 
The look of the perianth of Schepfia is not at an early pe- 
riod continuous with the calycule, if it be strictly so, it must 
be calycine. 
A genuine calyx must be continuous with the outer struc- 
ture of the part of which it isa development, if it be not
