ODONTOGLOSSUM TRIUMPHANS. Native of Colombia. 
A popular and striking species with large, ovate-elliptic, compressed pseudobulbs 
bearing two bright green leaves from 12 to 18 inches long, and dark green in 
colour. The scape is arching and often branching, and from 2 to 3 feet long. 
It carries a large number of flowers, each between 3 and 4 inches across. Sepals 
and petals brilliant yellow with blotches of deep brownish-crimson. Lip oblong, 
the apex extended into a narrow tail-like tip, the edges being toothed. The front 
part is light brown, the back portion white with a yellow centre. The white 
crest has two long teeth. Flowers in early Summer. 
Var. aureum.—Sepals and petals soft yellow blotched with deeper yellow. Lip 
white with large yellow blotches. Crest yellow and toothed. 
ODONTOGLOSSUM URO-SKINNERI. Native of Guatemala. 
A large growing species with stout, ovate, compressed, glossy, purple-spotted 
pseudobulbs growing from a creeping rhizome. The scape grows erectly from the 
base of the matured pseudobulbs, reaching a height of between 2 and 3 feet, and 
bearing a number of fine flowers, each nearly 3 inches in diameter. Sepals and 
petals chestnut brown mottled with green. The roundly cordate heart is mauve- 
purple mottled with white, the disk having two white crests. Flowers in Autumn. 
ODONTOGLOSSUM WALLISII. Native of Colombia. 
A slender species with ovoid pseudobulbs and narrow pointed leaves. The scape 
is slender and carries a few 24-inch flowers. Sepals brown with yellow margins. 
“Petals yellow spotted with brown. Lip white with a rosy blotch in the centre 
of the blade. Flowers in Spring and lasts well. 
The above are the principal species of Odontoglosswms. There are many more of 
them, but those not mentioned are of rare occurrence even in their native regions, 
so are very unlikely to be met with in Australia. 
There are many hybrids (both natural and man-made) available for cultivation, 
and the beauty of all the members of this genus is great enough to encourage 
growers to further efforts to establish them, even though first attempts have 
proved unhappy. 
The hybrids usually sold have, of course, been raised in artificial surroundings, 
and should, therefore, be more adaptable to our cultural conditions than species 
which have been torn from their harbourage on tree or rock and shipped overseas, 
but in most cases the hybrids will need rather warmer conditions than the species. 
I would recommend that all hybrid plants imported from England be moved 
under glass for the Winter months.
