kind somewhat further and higher, The relation of a leaf as foliage to 
the scale of a bud, or to the thorn of a Barberry is clearly of the same 
category as its relation to a sepal or a petal,—the latter, as we regard it, 
bringing in no new idea, and requiring no new point of v 
Next, Quincuncial imbrication is defined by Mr. Sie to be that 
arrangement in which “one petal is outside, an adjoining one wholly 
inside, the three others intermediate and overlapping on one side.” But

In the third place, we are eatery inclined to demur to the proposed 
modifications of the sense of the terms perigynous and epigynous ‘(paragr. 
140), Mr. Bentham sai the former to those cases in which th 
tals, d&c., are adnate to a perfectly free calyx, as in the Cherry, and 
applying the latter i in cases where the pele equally bearing the petals, 
&ec., is adnate even mens to the base of the ovary, if only the adhesion 
reaches above the level of the insertion of. the lowest ovule ;—which 
would make most Saxifrages epigynous. Besides the etymological ob- 
jections, and the inconvenience of a change, the new definitions seem to us 
be at least as ambiguous as the old in practice; and it is not surpris- 
ing that they are not uniformly adopted in the Hongkong Flora itself. 
Finally, as to paragr. 166, we are not much better satisfied with the 
definition that the radicle is the “base of the future rot,” than with the 
original statement that it is “the future root.” To us nothing in ye 
is clearer, or more patent to observation during germination, than that 
while the radicle is, if you please, “ the base of the future root” inasmuch 
as it is that from which the root proceeds, it is itself the first internode

If the ay sa failed to elongate, as in Monocotyledons, and in
