The polyphyllous series is represented much more numerously 
than the gamophyllous one, perhaps not by generic, but conspicu- 
ously by specific types; and in the present paper I have dealt 
only with the genera and species of the first two polyphyllous 
tribes, Scillew and Chlorogales—the latter, like its gamophyllous 
representative Odontostemonex, represented very scantily, but 
the former, Scillez, containing nearly as many species as the whole 
of the tribes of the gamophyllous series, exclusive of Aloinex, put 
together. 
In the way of general remarks, preliminary to the technical de- 
finitions of genera and species, I have exceedingly little to say. 
Scilleæ may be fairly taken as representing the endogenous type 
of structure in its most typical and symmetrical development ; 
and Scilla and Ornithogalum are plants so familiar to every one 
that it is quite needless to enlarge upon them. I shall therefore 
only pass the different organs briefly in review, and say a few 
words upon the modifications which they furnish to characterize 
genera and groups of species. 
Bulb.—There is no material difference in the bulbs of all the 
plants here included. All are proper typical bulbs of the tu- 
nieated kind. Two of them are of officinal interest, the Squill and 
the Californian Soap-plant. 
Leaves.—The leaves are usually contemporaneous with the 
flowers; but they are developed more or less decidedly after them 
in several species, as in our British Scilla autumnalis, and still 
more distinctly in several of the Urgineas. In Bowiea, a curious 
monotypic Cape genus with a wide-climbing habit, there are only 
a pair of small fleshy linear leaves, which vanish very early.
