 months. Mexico. 



S. oculata. — This species derives its name from 

 the peculiar eye-like spots on the side of the 

 hypochil, which are sometimes represented by one 

 pair, at others two pairs. Eacemes bearing nume- 

 rous large flowers. Sepals pale yellow, profusely 

 spotted with lilac or purple ; petals much narrower,

 wards the base with tawny-orange. The lip pale 

 yellow, dotted with pink, the hypochil tawny-orange.

S. tigrina. — This species produces the largest 

 flowers in the whole genus, often measuring eight 

 inches across. Sepals and petals very thick and

 spotted with reddish- orange. The hypochil orna- 

 mented with a large blotch of dark velvety-purple.

Stenorhynehus. — A small genus of terrestrial 

 Orchids, containing very few showy-flowered species. 

 The name is derived from its narrow column: stenos, 

 "narrow," and rhynchns," a beak." The various 

 members of this family are all natives of South 



America and the islands of the West Indies. For 

 soil use two parts of loam to one of peat, and 

 do not elevate the plant above the rim of the pot. 

 Supply freely with water until growth is mature, 

 when very little will suffice until fresh growth com- 

 mences. Brazilian House. 



S. speciosus. — Leaves broadly-oblong, waved at the 

 edges, dark green. Scape erect, longer than the 

 leaves, bearing large scarlet bracts, longer than the 

 flowers. Raceme dense and many- flowered. Outer 

 portion of flower scarlet ; petals and Up white. Its 

 brilliantly coloured flowers and bracts render it very 

 conspicuous. Spring and summer months. West 

 Indian Islands. 



Thunia. — A small genus of terrestrial plants, 

 which have been separated from Pkajus. They have 

 long terete, stem-like, deciduous pseudo-bulbs, and 

 terminal clusters of flowers. Pot-culture suits them 

 best. Plant them in rough peat, sphagnum moss, 

 and well-decomposed cow-manure. During the grow- 

 ing season these plants require an abundance of 

 water. After the flowering is over the leaves will 

 soon begin to fall, and very little water will be 

 sufficient to keep life in them until growth com- 

 mences again. East Indian House. 



T. alba. — Stems erect, two to three feet high, 

 clothed with glaucous, lanceolate, stem - clasping 

 leaves. Flowers in short, dense, terminal racemes. 

 Sepals and petals linear-lanceolate, longer than the 

 Hp, pure white. Lip white, streaked with purple 

 and lilac. Summer months. Xorthern India. 



T. Bensonice. — Similar in habit to the preceding ; 

 leaves sheathing at the base, about ten inches long, 

 linear-lanceolate, bright green above, paler below. 

 Flowers large, some three inches long, in dense 

 terminal racemes. Sepals and petals linear-lanceolate, 

 deep reddish-purple on the outside, paler towards the 

 centre. Lip three-lobed, rolled over the column at 

 the base, where it is white, spreading in front, 

 where it is rich deep purple, frilled on the edge, and 

 bearing several yellow-crested ridges on the disc. 

 Summer months. British Burmah. 



Tricho centrum. — From thrix, " a hair," and 

 centron, "a spur," in reference to the spur at the 

 base of the column. A small genus of dwarf tufted 

 epiphytes, only two species of which are worth 

 growing for their beauty. They should be grown 

 upon a block of w r ood, or in small earthenware 

 baskets, and kept moderately well supplied with 

 water all the season. Brazilian House. 



T. albo-purpureum. — Pseudo-bulbs ovate, bearing 

 oblong-lanceolate, coriaceous, bright green leaves. 

 Peduncle pendulous, one-flowered ; flowers about 

 two inches across. Sepals and petals brown, tipped
