ONCIDIUM LANCEANUM. Native of Dutch Guiana. 
This species is of the same habit and form as O. haematochilum, and has the same 
disabilities. Leaves, without pseudobulbs, spring from a stout rhizome. They are 
a foot or more in length, 3 inches wide, thick, leathery and green spotted with 
brown. The many-flowered spike is erect, branched and stout, the flowers being 
between 2 and 3 inches wide. Sepals and petals ovate, fleshy, yellow, barred and 
blotched with chocolate. Lip 14 inches long, narrowed in the middle, spreading 
and flat at the apex, pinkish at the base and violet in front. Flowers in Summer 
and lasts a month. Treatment as for O. haematochilum. 
ONCIDIUM LEUCHOCHILUM. Native of Mexico. 
A variable but beautiful species with ovate, flattened pseudobulbs, slightly fur- 
rowed, and bearing one or more pointed recurved leaves, each about 9 inches long 
and 1 inch wide. Flower spikes are very long (instances where they have extended 
to 10 feet having been recorded), branched and panicled. They bear a great num- 
ber of flowers each about 2 inches wide, with equal oblong sepals and petals which 
are yellowish-green blotched with dark brown. Lip reniform with a red stalk-like 
base, the two-lobed blade is white, turning yellow with age, with two small, white 
side lobes. Flowers at various times during the year, the blooms lasting five or six 
weeks. Treatment as for P. candida. 
ONCIDIUM LONGIPES. (Var. Croesus). Native of Brazil. 
A dwarf species with tufted, narrow, furrowed pseudobulbs about an inch tall, 
tapering into a neck at the top, and bearing two strap-shaped leaves about 4 
inches long and light green in colour. Flower spike, inclined outwards, is short, 
and bears up to half-a-dozen pansy-like flowers, each about 15 inches wide. Sepals 
and petals oblong and spreading and with recurved margins. They are reddish- 
brown in colour. Lip is three-lobed, the lateral lobes being almost circular, the 
front one large and kidney-shaped and nearly an inch across. It is rich golden- 
yellow in colour, and has a large blotch of black-purple around the toothed crest. 
Warm treatment as suggested for O. cornigerum. Flowers in late Summer. 
ONCIDIUM LURIDUM. Native of Trinidad. 
This species grows at low altitudes, generally on tall trees, but often on the 
ground in the heavy humus of the tropical forests where it has been blown by a 
passing storm. It is a robust growing plant with fleshy, pegriform pseudobulbs 
topped with broad, fleshy leaves about 24 inches wide and up to 18 inches long. 
The panicles spring from the base of the newly matured pseudobulbs. They 
are very long and slender, and the flowers are borne on short, lateral branches at 
intervals along the stem, usually from four to eight blooms appearing on each 
branch. The flowers are yellow with fringed margins, the column being white 
marked with black and pink. This plant requires plenty of moisture and sunlight. 
In Brisbane it will do passing well in a basket suspended from a tree. In Sydney 
glasshouse treatment will be needed; while in Melbourne and Adelaide heat is 
essential. Flowers in Summer, the blooms remaining perfect for three or four weeks.
