of the peduncle is obliquely inserted a simple coloured perianth' of 5 
somewhat dissimilar’ leaves, whose edges touch below’ to form a long 
Embothrium (Oreocallis) grandiflorum.

1 All authors are not agreed as to the mor- 
phological signification of’ this perianth. Those 
who compare it with that of Loranthacee, Santa- 
lacea, Olacacee, &c., consider it a corolla, con- 
trary to those who side with JussrEv in taking it 
as a calyx. Without denying the analogies of 
Proteacee with the above orders,we think that the 
development of the perianth asobserved by PaYER 
(Organog. Comp., 473, t. 97) indicates a corolla 
rather than a calyx, for its leaves appear succes- 
sively, not simultaneously asin Santalacez. We 
shall, however, avoid committing ourselves deci- 
dedly on this point, and simply employ the terms 
‘perianth” and “leaves” (“fololes’”’) in our 
descriptions, 
2 The dissimilarity is chiefly below, owing to 
the obliquity of the receptacle. As this is cut 
obliquely downwards and outwards, the anterior 
leaves are naturally a little the longer. 
®* They often remain united at the apex; while 
about half-way up two separate from one another, 
part of the style escaping through the cleft. Its 
stigmatiferous apex remains long afterwards still 
caught between the stamens and the parts of the 
perianth on a level with the anthers. However, 
even these parts finally separate, and the leaves 
commence folding or bending back. This occurs 
in a large number of the members of this order.
