160 A FEW HINTS ON THE MANAGEMENT OF TERRESTRIAL ORCHIDEiE. 
O. speculum. One of the prettiest of this genus ; a native of Portugal : 
introduced in 1818. It requires a slight shelter, and will grow in any light sandy- 
soil, requiring the same treatment as the others. 
PERISTERIA. 
P. elata. This is a splendid species ; a native of Panama, from whence it 
was sent to R. Harrison, Esq., of Liverpool, by H. Barnard, Esq., in 1826. The 
flower-stem springs from the base of the large pseudo-bulb, and grows four feet or 
more high ; and producing many yellowish-white waxy flowers, of pleasant fra- 
grance. The inside of the flower bears a striking resemblance to a dove with its 
wings expanded. This species requires the heat of the stove, and should be potted 
in a mixture of rotten vegetable earth and sandy peat ; and must not be over 
watered at any time of the year. 
PHAJUS. 
P. maculatus. A fine species, native of Nepal. The flower-stem rises two 
feet or more high, and produces ten or twelve yellow-green flowers. It requires the 
heat of the stove, but is impatient of over dampness, and should therefore be placed 
in any cool airy part. It should be potted in loam and peat. 
P. grandifolius, or Bletia Tmikervillice, is so well known, and the culture 
so easy, that it is unnecessary to say anything about it here. 
POGONIA. 
P. ophioglossoides. A native of North America, brought into this country 
in 1816. It requires the shelter of the greenhouse or frame, should be potted 
in sandy loam and turfy peat, and is propagated by division of the roots. 
SATYRIUM. 
S. carnbum is a native of the Cape of Good Hope. The flower-stem grows 
about eighteen inches high, and produces numerous pink flowers. It requires the 
protection of the greenhouse, and should be planted in well-drained pots, filled with 
sandy peat. 
STENORHYNCHUS. 
S. speciosus. This is a very beautiful species, a native of the West Indies, 
from whence it was introduced in 1790. The flower-stem grows about a foot high, 
and is thickly clothed more than half that length with brilliant scarlet flowers. It 
is a herbaceous plant, and may be increased by division of the roots. 
8. orchioides is also a very charming kind. The flower-stem grows taller 
than that of the last, reaching about a foot and a half, and producing numerous 
flowers. It requires the same treatment as the last ; viz. the heat of the stove, to 
be potted in sandy peat soil, well- drained, and increased by division of the roots.
