292 ORCHIDS. 
M. Harryana represents the robust-growing, free-flower- 
ing kinds which thrive in as low a temperature as is 
advisable for any cool Orchid. It has been successfully 
grown in an unheated frame, being protected from frost 
by mats; but it is, of course, safer when grown in a 
house the temperature of which in summer is as cool as 
possible, and the atmosphere moist. The leaves are easily 
scorched by bright sunlight. The plants should be grown 
in well-drained pots, using a compost of two parts rough 
peat and one part sphagnum, with a sprinkling of silver 
sand. The soil should be kept moist all the year round, 
and almost saturated in summer. The most favourable 
time to re-pot is February, when the soil should be shaken 
away from the roots if at all sour, and the dead roots cut 
away. It is not unusual for a large proportion of the 
roots to die during winter. 
M. ignea.—A pretty, bright-flowered species, and one 
of the most popular. The leaves are semi-erect, 6in. to 
gin. long, with a long, attenuated, stalk-like base, rounded 
at the apex, 1}in. across, fleshy, dark green. The scapes 
are gin. to 12in. long, erect, one-flowered. Each flower has 
a short, curved tube, so that the sepals face horizontally ; 
the upper one is narrow, tailed, decumbent, rin. long; the 
two lower ones are joined half-way down, broad-ovate, 
sharp-pointed, 14in. long, flat, 14in. across the pair; colour 
orange or flame-red, with six broad, crimson lines. They 
are fleshy in substance, and remain fresh on the plant for 
about six weeks. This species should be grown as advised 
for M. Harryana. It blossoms in winter and spring. Speci- 
mens with over forty flowers open are sometimes shown. 
Introduced from New Grenada in 1871.
