pot a size larger, if the growth made warrants it. This annual repotting will 
prevent souring of the compost which is detrimental to the plant. 
The following are the best species:— 
ODONTOGLOSSUM APTERTUM. Native of Mexico. 
A strong growing species with large pseudobulbs, carrying two green leaves each 
9 inches long by an inch in width, Flower-scape stout and about a foot in length, 
carrying from three to seven good sized blooms, each about 3 inches across. 
Sepals and petals white, spotted at the base with reddish-brown. 
Syn. O. nebulosum, 
ODONTOGLOSSUM BICTONIENSE. Native of Guatemala. 
A robust species with ovoid, compressed pseudobulbs clothed with two or three 
sword-shaped, somewhat undulated leaves about a foot long, with prominent 
nerves, and bright green in colour. The scape is upright and grows from the 
matured bulbs, reaches to a length of two feet and carries a number of beautiful 
flowers each about 1} inches across. In the type form they are yellowish-green 
with a brownish-purple blotch. Lip is lilac and undulated. Flowers in Autumn 
and lasts a long time in perfection. 
Var. album.—Sepals and petals chestnut-brown, lip white. 
Var. splendens.—Green and brown sepals and petals, lip pink. 
Var. superbum.—Sepals and petals chocolate, lip large and purplish-mauve marked 
with darker lines, 
ODONTOGLOSSUM BLANDUM. Native of Colombia. 
A small species with small pseudobulbs rarely more than an inch in height. The 
two leaves are about 9 inches long, narrow and pale green. Spike is about 10 inches 
long and bears anything up to a dozen charming flowers with sepals and petals 
equal and tapering to a point. They are white spotted and blotched with reddish- 
purple. Lip has brown, triangular blade, sharply pointed at the apex, same colour- 
ing as the segments with a yellow crest and two erect narrow teeth. Requires 
rather warmer treatment than most of the Odontoglots, but should do well 
enough out of doors in Brisbane during the Summer if it is moved to a glass- 
house in the cooler months. 
Var. albo-cupreum.—Segments pale yellow with coppery bars and bands. Labellum 
pure white with yellow crest. 
Var. Rossianum.—Sepals and petals white spotted with brown. Lip yellow, the 
base spotted red and the front spotted and barred with lavender.

A charming species with oblong, compressed, two-leaved pseudobulbs up to 4 
inches tall. The leathery leaves are oblong and about a foot long. The flower 
spikes are stout and branching, and carry a number of handsome flowers, each
