7 feet. Flowers very large, sometimes 7 inches across. Sepals oblong, petals some- 
what broader. Whole flower rich purple with a yellow spot at the base of the lip. 
Flowers more or less continuously for two to three months, although the in- 
dividual blossoms last little more than a single day. Summer flowering. 
Var. Kienastiana——Pure white with a small greenish-yellow mark at the base 
of the lip. 
Var. nana.—Dwarf growing. Flowers deep purple and crimson. 
Var. pallida.—Sepals and petals rose-pink, lip white with a tinge of rose. 
SOBRALIA SESSILIS. Native of British Guiana. 
Stems slender and reedy, from 12 to 24 inches tall. Sepals and petals oblong and 
spreading and pure white, the petals being a little longer and broader. Lip cream 
to light yellow, tinged with rose pink, the front lobe being undulated at the 
edges. Flowers are about 2 inches across. Blooms in succession for a long time. 
SOBRALIA XANTHOLEUCA. Native of Mexico and Honduras. 
Similar in habit to S. macrantha, but does not grow to so great a height. Sepals 
and petals narrowly oblong. Pale lemon yellow. Lip a deeper yellow. Large 
flowers with the same characteristics as other species. 
SOPHRRONELIS 
A genus of dwarf growing, epiphytical orchids of which only three species are 
known. They have been used in the creation of hybrid genera with both Laelias 
and Cattleyas. They like reasonably cool conditions, and can be grown in an ordin- 
ary bushhouse in the warmer parts of Brisbane and the North, while cool glass- 
house treatment will be preferable in the cooler parts. A compost of osmunda 
fibre, or osmunda and polypodium in a 50/50 mixture, lightly covering ample 
drainage, will suit. Ample moisture is necessary while growth is in progress and 
even in Winter they should be kept damp. 
SOPHRONITIS CERNUA. Native of Brazil. 
A very small species with little two-edged, stem-like pseudobulbs about half an 
inch long, growing from a creeping rhizome and topped with a single broadly- 
ovate, dark green leaf about 1 inch long. The flowers are produced on a short 
peduncle which bears from 4 to 8 small, scarlet flowers, each about 1 to 1} inches 
across, with a short, narrow, pointed, yellow lip. Flowers in Winter and lasts 
some weeks.
