THUNIA BRYMERIANA. Native of Burma. 
Similar in form to T. Marshalliana. Stems about 2 feet high. Sepals and petals 
white. Lip is yellow with radiating crimson lines. 
THUNIA MARSHALLIANA. Native of Burma. (Illustrated. ) 
Probably the finest species, with reed-like stems 2 to 3 feet high and typical foliage. 
Flowers produced in the usual terminal raceme. They are about 5 inches across 
with lanceolate-oblong, acute, spreading sepals and petals. They are pure white 
except the front part of the large lip, which is rich golden-yellow veined with 
orange-red. Disk has five yellow, raised veins and five shorter ones on each side. 
This plant flowers in midsummer and it is almost axiomatic that, if the flower 
scape is not in appearance by the first week in December, it will not flower that 
year. 
TRICHOCENTRUM 
A genus of dwarf epiphytes with tiny, ovoid, single-leaved pseudobulbs which 
send out short scapes from the bases of the pseudobulbs. These bear one or two 
small flowers. Most species are of botanical interest only, but one or two are 
worthy of inclusion in collections if the opportunity offers. They do best in a 
shallow basket in a compost of osmunda or polypodium fibre. They need plentiful 
water during the growing period, but only sufficient in Winter to prevent the 
plants from losing condition. They require rather warm conditions, but in the 
North ordinary bushhouse treatment will serve, while in Brisbane a glasshouse, 
and in the South artificial heat, will be necessary in the Winter. 
TRICHOCENTRUM ALBO-PURPUREUM. Native of North Brazil. 
A pretty species with very small pseudobulbs and oblong, acute, shining green 
leaves 4 to 6 inches long. Flower spikes bear a single flower about an inch across 
at the widest part. Sepals and petals bright cinnamon-brown inside, tawny-yellow 
outside. Lip large, projected forwards, fiddle-shaped, broad and bilobed in front, 
white with two large purple spots near the base. Crest marked with four rosy- 
purple keels. Flowers Autumn. 
TRICHOCENTRUM ORTHOPLECTRON. Native of Argentine. 
Flowers comparatively large. Sepals and petals light cinnamon-brown, tipped with 
yellow. Lip large, white with a crimson lake blotch each side of the base, with 
five keels of the same colour between them. Disk yellow. Flowers Autumn. 
TRICHOCENTRUM TIGRINUM. Native of Ecuador. 
A desirable species with oblong leaves dotted with deep red. Peduncles one- or
