genus Gesneria, this really splendid plant is unequalled among 
its congeners. It most nearly resembles G. zebrina , but has not 
the finely marked foliage of that species : in general aspect there 
is evident resemblance, and, with the exception just referred to, 
it not only possesses all the properties of the species under com¬ 
parison, but does so in a more eminent degree, and is devoid of 
its stiffness and formal appearance.— Pax. Mag. Bot. 
ORCHiDACEiE. —Gynandria Monandria. 
Saccolabium ampullaceum. A scarce and valuable plant, from 
the forests of Sylhet, from whence it was obtained and brought 
over by Mr. J. Gibson, his Grace the Duke of Devonshire’s col¬ 
lector. Except in its flowers, it does not in general appearance 
materially differ from some species of the same and allied genera. 
It is of medium strength, and there is a pleasing proportion be¬ 
tween the size of the flower-spikes and the plant, very unfrequent 
in the section to which it belongs. The flowers are borne on 
shortish spikes, and are remarkable among its division as being 
self-coloured, and are still more so among Orchidece , from the 
unusualness of their colour, which is bright rose.— Pax. Mag. 
Bot. 
Sarcochilus calceolus. This very singular species is a native 
of Manilla, whence Mr. Gumming sent it to Messrs. Loddiges. 
The lengthened stem is at variance with the usual habit of Sar¬ 
cochilus, as also is the lip, so far as the very large size of its 
middle lobe is concerned; hut no distinction appears to exist. 
The flowers are entirely white, except that the lip has a faint 
tinge of yellow, and some few streaks of crimson at its base. —

CALENDAR FOR MAY. 
The season is now advancing when the various species of 
caterpillars and grubs will become numerous and destructive, if 
all possible means be not taken to thin their numbers as much as 
possible. Good service will have been done towards this end in 
the fields, pastures, and lawns by rooks, fieldfares, starlings, and 
other birds, where they have not been disturbed, who, in mild 
winters and early spring, destroy enormous quantities of the 
grubs of the cockchafer, Harry-long-legs, and also of the wire-
