Presented by the Honourable Court of 
Directors of tlie East luclia Company, among 
whose collections it often occurs. 
This little Orchid is one of a set scarcely 
known in gardens, the peculiarity of which 
consists in the stem when fully formed being 
nothing more than a pseudo-bulb. These little 
pseudo bulbs are compressed bodies, in form 
not unlike a flat flask, and piled one over the 
other in the singular manner shown in the 
annexed cut, which represents the plant of its 
natural size. The flowers are white, smooth, 
with a slight tinge of green, but otherwise 
eolourless. The lip is three lobed, with three 
elevated parallel lines, the middle lobe the 
longest, oblong, and acute. The foot of the 
column is neither chambered nor toothed. 
In all respects this plant is so entirely an 
Eria that it is referred to that genus, notwith¬ 
standing that, in the flowers examined, the 
number of its pollen masses was only four, 
instead of eight. But this may have been 
accidental. In its three-ridged lip, and re- 
flexed bracts, it so strongly calls to mind that 
genus, as to raise a reasonable presumption 
that the number of pollen masses would, in 
more perfect flowers, be as usual. 
A hothouse plant of no horticultural in¬ 
terest.—( Hurt . Soc. Journal.) 
In a recent number of the Revue Horlicole, 
M. Dupuis, of the imperial school at Grignon, 
has some observations on the two species of 
Gymnogrannua, Aurea and Argentea, and he 
introduces what he considers a distinct variety 
under the name of G. hybrida Mart., called, 
by Link, Ceroptcris Martensii. It is described 
as having the fronds bipinnate, with the pri¬ 
mary divisions attenuated at the summit; 
the pinnules are oval lanceolate, serrated; 
the lower ones pinnatiftd, the upper ones 
joined at the base; all the fronds are said to 
be covered with a pale yellow powder. 
It is stated that the two well-known 
species were grown for some time near each 
other in one of the houses of the Botanic 
Garden, Louvain, and no other Ferns were 
in the house; the sporules of G. aurea were 
sown by M. Donkelaer, the gardener, and the 
young plants which sprung up were, in general, 
as to form, habit, and all the characters, inter¬ 
mediate between Aurea and Argentea, being 
even more like the latter than the parent plant; 
at least, the fronds had more of the vigour of 
Argentea than the delicate elegance of Aurea. 
M. Pepin, of the Garden of Plants, has a 
note on the effects of sulphur on Camellias 
'and other kinds of house plants, to show 
that, though sulphur may be good for Vines and Peaches, 
there is danger in using it for other plants in the same 
manner. He mentions an instance in which the gar¬ 
dener of a gentleman residing in Paris had applied it, in 
the month of October, to young Camellias covered with 
insects, thinking, as it is stated, that by this plan he would 
get rid of them in the same way as those on the Peaches 
treated for blight in the open ground. But as the con¬ 
ditions were very different, the results were not the same. 
It appears that the Camellias in question, about fifty in 
number, were from three to six feet high, planted out in 
clumps and en espaliers ; some of them only were in pots. 
Those in the clumps were trained in the pyramidal form, 
and the others in the fan form along the walls of the house. 
The borders of the clumps were filled with miscellaneous 
plants, having a margin of Lycopodium Brasilicnse. Shelves 
running round the house were filled in the same way. 
[Erla aeervata.] 
The sulphur was applied in the evening, and next 
morning the ground was covered with Camellia buds) 
Some days after the young branches were affected seriously, 
and, subsequently, the whole of the wood down to the very 
roots, so that, with the exception of Donkelacrii, mutalilis, 
Cliandlerii, and elegans, the whole of the Camellias died. 
Among the ligneous plants saved, the principal are a Ficus 
elastica, about seven feet high ; the buds and terminal 
leaves, however, have been much affected. With this were 
a Draceena australis and some varieties of EpiphyUnm Acker - 
manni. It appears that the Lycopodium which formed the 
margin, twenty-five varieties of Azalea in pots, a collection 
of Heaths, Habrolhamnus elegans , Clematis Japonica, Passi- 
Jiora Relolii, Daphne Indica, and more than a hundred other 
plants of similar kinds, have been destroyed by the sulphur¬ 
ous vapour which was produced during the night in the house. 
M. Pepin observes, that, as is well known, sulphur is
