and substance, which are sometimes quite distinct from on(^ 
another, and sometimes united along their borders. In Draccena 
the pedicels spring out of the rachis in bundles of two or three, or 
in some species of many together, without any such regular arrange- 
ment of bracts and bracteoles as I have just described. The pedicels 
in Draccena are usually longer than in Cordyline^ and the perianth 
is united through a greater portion of its length, but this does not 
hold good invariably, and in the shape of the leaves there is very 
much the same range of variation in both. Dr. Kegel adds that 
Lraccena may be distinguished also by its orange -coloured roots and 
by the absence of runners, but these latter are present in the 
African B. surculosa. The number of ovules and seeds, the shape 
of the stigmas, and the arrangement of the pedicels and bracts are 
the points on which it is safe to rely, and the two genera were 
separated by Jussicu when he laid the foundations of the Natural 
System in 1789, and have been adopted by Robert Brown, End- 
licher, Meisner, Kunth, Dr. Hooker, and all other writers who 
have had occasion to deal with them. 
The geographical distribution of the two genera is not dissimilar. 
They are both spread through Tropical Asia and North Australia, 
and are, both entirely absent from Europe and America; but whilst 
there are several species of Draccena in Tropical Africa there are 
no Cordylines, and the latter, on the contrary, stretches into New 
Zealand and Polynesia, wherQ Draccena does not reach. An ex- 
cellent monograph of all the known species of Draccena has lately 
been published by Dr. Kegel in the " Gartenflora," and there is 
an account by Dr. Hooker of the New Zealand and Australian 
Cordylines in the volume of the " Gardener's Chronicle " for 1860, 
and two later descriptive lists of all the known species and forms 
have been published by Dr. Karl Koch in the Berlin " Wochen- 
schrift." 
I will conclude with a list of forms of Cordijline which within 
the last few years have been placed in circulation in horticulture 
as species of Draccena. None of them, so far as I know, have been 
botanically described, and we shall probably not be far wrong in 
assuming that most of the names in the following list represent 
mere forms of Cordyline terminalis^ varying in the shape, size, and 
colouring of the leaf. I need scarcely point out that the distribution 
of slight varieties of an old well-known plant under new specific 
names appended to a genus to which they do not belong has a great 
tendency to cause confusion in the minds both of gardeners and bota- 
nists ; and I hope tliat in tliis particular case the Horticultural
