116 THE ORCHID REVIEW. [| APRIL, 1923. 
petals sometimes tinged with green. Sepals and petals nearly uniform, 
about 24 inches long, with undulated margins; lip clawed, the blade large, 
expanded, obscurely four-lobed. The variety nobilis has shorter and thicker 
pseudobulbs ; flowers a little larger with the sepals and petals always pure 
white, the blade of the lip a little broader, and with the yellow spot 
enlarged. T. candida is asynonym of T. fragrans. 
T. Galeottiana was discovered by Galeotti, an Italian explorer, some 
time before 1845, growing on oaks at an elevation of 3,000 feet near 
‘Teotaleingo in Mexico, Sepals and petals similar, pale tumeric-yellow, 
lip adnate to the column at the base, the blade four-lobed, light yellow with 
a darker yellow disc that is sometimes spotted with red. Column 
greenish. 
T. hymenantha is easily distinguished by the absence of pseudobulbs, by 
its long narrow fleshy leaves and by its nearly flat labellum. Flowers 
nearly 2 inches in diameter, sepals and petals similar, light straw-yellow, 
but sometimes white; lip broadly oval, fringed at the margin, white 
sparingly spotted with deep claret-red and covered with crystal dots. This 
Trichopilia was first discovercd by Schlim in the eastern Cordillera of 
Colombia near Ocana, and most likely introduced by him. 
T. laxa has much compressed pseudobulbs, 2-3 inches high, leaves 8-12 
inches long, and scapes 6-12, flowered. Unfortunately, it does not possess 
any attractive colours. Sepals and petals pale rose with a greenish median 
band, lip white, obscurely three-lobed, the basal lobes rolled over the 
column. It was discovered by Hartweg in the same locality as T. fragrans, 
about the year 1841. 
T. rostrata was discovered by one of Messrs. Low’s collecters In 1866, 
and introduced from Colombia a few years later. Pseudobulbs much 
compressed 4-6 inches high, leaves narrow, 4-7 inches long, scapes sub- 
erect, sepals and petals light yellow-green, twisted, lip white with 
some yellow markings on the disc, spotted and marked with orange in 
the tube. 
T. sanguinolenta has compressed pseudobulbs 1-2 inches high, leaves 4-7 
inches long, scapes sub-erect, sepals and petals olive-green, barred and 
spotted with chestnut-brown, the spots on the petals ocellated ; lip oblong, 
two-lobed at the apex, white, spotted and marked on the basal half with 
red-purple. This interesting species, also known in gardens as Helcia 
sanguinolenta, was discovered by Hartweg on the Ecuadorean Andes in 
1841. He sent it with other Orchids from the same locality to the 
Horticultural Society of London, in whose garden at Chiswick it flowered 
soon after. 
T. suavis also has much compressed pseudobulbs, about 3 inches high, 
leaves 4-9 inches long, sometimes more. Flowers large, fragrant, the sepals 
slab asain
