the very narrow gland fining away to each side, sufficiently dis¬

Odontoglossum membrancLceum. This delicious species foi so 
it deserves to he called, on account of its agreeable odour and 
delicate flowers—this delicious species is quite like O. Cervantesii 
in general appearance, and may possibly be a mere variety oi it. 
It differs, however, in the following respects: the flowers are 
whiter and rather larger, and the lip is spotted at the base. Its 
petals are much blunted. Its lip is very deeply heart-shaped, 
and quite rounded at the point. The two front teeth ot the lip 
are shorter and less hairy, and the concavity at the base ot the 
lip has a much smaller central tubercle. In other respects the 
two plants may be regarded as being identical, they aie both 
Mexican, and may be regarded as among the finest species of that 
country.— Bot. Reg. 34-46.

The rapidly increasing taste for the pure, intellectual, and 
tranquillizing pleasures derivable from the pursuit or horticulture

development of available means for its enjoyment, ready and 
approachable ; the removal of supposed difficulties, which 
ever present themselves to the imagination of a beginner ; and 
the free, full, and unrestrained communion of ideas which the 
experienced may supply with so much advantage to the un¬ 
initiated—a degree of duty imposing itself on all connected with 
the science, to keep alive the existing interest, and to make its 
future advances extended, beneficial, and permanent. With this 
view of the case, we have determined on an occasional enlarge¬ 
ment of our space, that we may have increased opportunity of 
contributing to this desired end; and by treating the subject in 
detail, be enabled to place it in a thoroughly comprehensible 
view, with the advantage of being easily inferred to. 
The subject of the present paper is one which, let its size or 
position be what it may, is perhaps the most important, because
