PHALZENOP SIS. 413 
Another charm of Phalzenopses is their remarkably free- 
flowering nature; P. Schilleriana has been known to bear 
over 170 flowers on a raceme, and as each flower is 2in. 
to 3in. across, very full and spreading, its splendid appear- 
ance may be easily conceived. In regard to the individual 
flower, the genus may be roughly divided into two sections: 
the one in which the sepals and petals are about the same 
size, and the lip is undivided at the apex—represented by 
P. Luddemanniana and P. violacea—and the other in which 
the petals are much larger and broader than the sepals, 
and where the apex of the lip separates into two divergent 
horns, which in some species assume quite a thread-like 
form. To the latter section the showiest species belong. 
A valuable property is the length of time the flowers remain 
in beauty; indeed, in cases where the plants are not in 
the most vigorous state, it is advisable to remove the flowers 
before they naturally fade. 
Culture.—Growing, as has already been stated, in some 
of the most tropical regions of the globe, on the trunks of 
trees and on the sides of rocks, Phalznopses’ luxuriate only 
under conditions of great heat and moisture, and especially 
is this the case during the period of active growth. During 
winter the plants should be kept in a temperature of from 
65deg. to 7zodeg., which after February, when signs of 
growth will re-appear, ought to be gradually raised until at 
midsummer it reaches 7odeg. to 75deg. by night, with a 
natural rise of todeg. by sun-heat in the daytime. In bright 
sunshine they require to be shaded, a thin tiffany blind being 
the best for this purpose. The most essential factor in the 
culture of these plants is probably the moistness of the 
atmosphere in which they grow. In the active season it 
should be kept as near saturation point as possible, and 
whilst in the shorter days it should be regulated in proportion 
to the temperature, anything approaching dryness is harmful
