dated. Hence Exogens have been broken 
up into, 1 . Exogens proper, or those having an 
ovary, style, and stigma ; and 2. Gvmnogens, 
which have neither. 
" Among Endogens no difference has been 
remarked in the mode of propagation, but a 
material peculiarity has been noticed in the 
manner of growth. In the, great mass of the 
class the stem and root are formed in a similar 
way, or there is no considerable difference 
between them, and the leaves have no articu- 
lation with the stem ; but in a part of them 
the root is exactly like that of an Exogen 
without concentric circles, and the leaves fall 
oft" the stem by a clean fracture, just as in 
that class. Such fundamental distinctions have 
given rise to the separation by me of Endogens 
into 1. Endogens proper, and 2. Dictyogens." 
—P. 1—4. 
This, as the author observes, gives for the 
whole vegetable kingdom the seven classes 
which we have already quoted, to show the 
difference between the same author's notions 
in 1833 and 1845. At some other period we 
may give a specimen of some one order, with 
its details, but for the present we must dismiss 
the work, which we acknowledge to have read 
with considerable interest. In conclusion, we 
strongly recommend all those who desire to be 
made acquainted with the merits of the Natural 
System, to procure and carefully peruse this 
volume. It comprises all that has been, or 
that, in the present state of things, can be said 
upon the subject. The embellishments of each 
order are finely executed ; and it has the 
merit of being more intelligible and instructive 
than any other we have seen on the subject. 
NEW ORCHIDACEOUS PLANTS, 
INTRODUCED OH MADE KNOWN DUIUNG 1845-6 
Utluntuyiu*uLi;i GeFoantesii. 
The species of this fashionable and inter- 
esting family of plants, which are enumerated 
below, have been introduced to our gardens, 
or have been made known subsequently to the 
commencement of the year 1845. Some of 
the kinds here named, are exceedingly beau- 
tiful ones ; but others are possessed only of 
botanical interest. 
Aekides sr. — Two new species of Aerides 
were flowered during the last summer, by 
Mr. Eyles, of Roehampton. One, the A. 
roseum of Messrs. Loddiges, with a long 
narrow raceme of purple flowers, is in the 
way of A. offine. The other more nearly 
resembles A. crixpum. They were exhibited 
at Chiswick. 
Anurjecom apiculatum, Hooker. (Api- 
culated Angrtecum.) — This is rather a hand- 
some species, with a short leafy stem ; the 
leaves areobovately-lanceolate, and distichous, 
that is, arranged in two rows, opposite each 
Dither. The flowers are borne in a drooping 
axillary raceme ; they are white and spread- 
ing ; the sepals, petals, and lip, arc nearly 
uniform. It is allied to A. bilobum, but differs 
in not having its leaves two-lobed at the 
extremity ; and in not having the rachis and 
peduncle warted. It is a native of Sierra 
Leone, and was introduced by Mr. "Whitfield. 
Fig. in Sot. Mag. t. 4159. Quite new. 
Anguloa uxiflora variety. (One-flowered 
Anguloa.) — A superior variety of this rare 
plant, with delicate pink instead of cream-co- 
loured flowers, is grown by Messrs. Veitch, who 
exhibited it in the Regent's Park during 1845. 
Ansellia africana, Lindley. (African 
Ansellia.) — This is a very rare stove plant, 
introduced from Fernando Po, in Africa, and 
named after the gardener who was attached to 
the unfortunate Niger expedition. It has long 
erect stem-like pseudo-bulbs, from the top of 
which and from among the long narrow leaves, 
the flower-stalk arises. This is branched at the 
base, and somewhat drooping; and has altogether 
a very elegant appearance. The flowers are 
of a greenish ground colour, thickly marked 
with dark-brown spots, and the lip is yellow. 
Messrs. Loddiges have recently M ned the 
first plant which has been seen in (lower in 
Europe. Fig. in liot. ltcg. 1*46, t. 30.
