CLASS II.— PLANTS WITH ONLY ONE COTYLEDON (MONOCOTYLEDONEJE). 
THE NARCISSUS TRIBE (aM ARYLLIDEtE). 
Zephyranthes Drummondi. Drummond's Zepliyranthes. An elegant 
little bulbous plant, gathered in Texas by Mr. Drumraond, after whom it is speci- 
fically named. The flowers are of a pale pink, produced upon a long tube, and must, 
seen naturally, have a gay appearance. BiHt. Fl. Garden^ 328. 
THE ORCHIS TRIBE (ORCHIDE^). 
Stanhopea insignis. Nohle Stanhopea. This wonderful plant was originally 
found by Messrs. Humboldt and Bonpland on the trunks of old trees in shady 
woods near Cuenca in Quito, but has since been met with in various districts in 
South America. Dr. Lindley says, " In order to see its curious blossoms in perfec- 
tion, the young spikes should be watched, and, as soon as they appear, they should 
be artificially led over the edge of the pot or basket, otherwise their tendency to 
turn downwards is so great that they are apt to force themselves into the earth and 
to become smothered. Naturally it fixes its pseudo-bulbs upon branches, clinging 
to them with its numerous creeping roots, and suspending in the air its stout zig- 
zag spikes of fleshy wax-like flowers." Bot. Reg., 18-37. 
ORCHIDEiE. 
CoRYANTHES MACRANTHA. Large fiow ST ed Coryanthes. "Accustomed as 
we are now become," says Dr. Lindley, " to strange forms amongst orchideous plants, 
I doubt whether any species has yet been seen more remarkable for its unusual 
characters than Coryanthes macranthaJ' The plant has the habit of a Stanhopea or 
Gongora ; and pushes forth from the base of its pseudo-bulbs a pendulous scape, 
on which two or three flowers are developed. Each flower is placed at the end of a 
long, stifi", cylindrical furrowed ovary, and when expanded measures something more 
than six inches from the tip of one sepal to that of the opposite one. In colour, the 
sepals are an ochrey yellow, spotted irregularly with dull purple ; they have a most 
delicate texture ; the upper sepal falls back from the tip of the ovary ; is narrow, 
and not above one half the length of the two lateral ones, which, instead of apply- 
ing themselves to the tip, as is usually the case, turn directly away from it, placing 
themselves at an acute angle with the upper sepal, and after a while collapsing at 
their sides till they look something like bats' wings half at rest. 
OPERATIONS FOR MAY. 
All kinds of half hardy plants, that are intended to fill up vacant spaces in the 
flower garden by being disposed singly, or two or three together, in appropriate 
parts of the beds, borders &c., or those that are intended to occupy a whole or a part 
of a bed by several sorts being grouped together with a view ultimately to produce 
a dense mass of varied blossoms, may now safely be placed in those situations where 
they are intended to flower. The above hints embrace the many varieties of 
Salvias, Verbenas^ Lobelias, Petunias, Alonsoa, Calceolaria, Mimulus, &c. Also 
the common scarlet and other Geraniums, and any common green-house plants that 
are desired for flower-garden purposes may now be plunged where they are to
