aris. Linear-leaved lanceolate Hovea ; — it is a native of New Holland, from 
whence it was introcjuced some years ago ; it differs from the true Hoi'ea 
Lunoeoliitu, only in the narrowness of its leaves, the flowers grow in pairs, 
from the axilla of the leaves, and are of a violet-purple colour, with darker 
coloured wings. MuxiUdna 7* (?»Y/gv)««, Four-cornered Maxillaria; this spe- 
cies is deficient in beauty, the flowers being of a greenish yellow colour, but 
remarkable for its rich fragTance, which much resembles fresh violets; it is a 
native of Rio Jaiiiero, from whence it was imported by the Horticultural 
Society. Salvia Fuliosa, Leafy Mexican Sage; — a native of Mexico, where 
seeds were collected by Mr. Graham; it is a hardy annual, flowering in Au-

Qiiercifolia, Oak-leaved Eanksia; — this shrub is a native of Lewin's Land, 
in New Holland, whence it is said to have been introduced in 1805; it ap- 
pears to flower very rarely ; the heads of the flowers are on short stalks, and 
about three inches in length, the segments of the calyx are remarkably re- 
flexed, and each elongated into a slender, subulate, brown point, which is what 
Mr. Brown calls being aristate, covered with hairs of the same nature as those 
upon the rest of the calyx, except that they are shorter. Cheirdntlim Miitci- 
liil'is, Changeable Wall-flower ; — a beautiful half-shrubby plant, a native of 
Teneritfe; it requires the protection of a green-house in winter, and may be

purple. Ilimt'inciili's ('rrl/cux, va.r. Afu(Top/i>/lli(s; — it was introduced so long 
ago as the year 16oS, and cultivated in the Botanic Garden at Oxford, but seems

ino- wcis taken, was found in Tenerifi'e or the neighbouring islands, by P. B. 
Webb, Esq. it requires the protection of a frame in winter; the colour of the 
flower is yellow. Eub'qihiu Mackaidna, Mr. Mackay's Eulophia; — this most 
lovely species is, of all the Orchideous tribe, one of the most deserving culti- 
vation • it thrives well in pots filled with moss or rotten wood, and is easily 
increased by separating the pseudo-bulbs with a few roots attached to them ; 
it is a native of Brazil, whence it appears to have been introduced by Mr. 
Mackay, ofthe Dublin College Botanic Garden j the flowers are less perish- 
able than those of many of the Orchis tribe; their sepals and petals are green- 
ish, spotted with irregular blotches of brownish purple; the labellum is a 
brio'ht blue, deeply stained with darker lines, and has at its base a remarkable 
fleshv elevated, lunate, transverse ridge. (Ytsxia ilerberlidna, Mr, Herbert's

Contains a variety of specimens, which, though not of so ornamental a nature
