Celogyne Dayana is a plant of evergreen habit, and is furnished with long narrow 
—almost cylindrical—pseudobulbs which bear dark green foliage. It produces its long 
pendulous inflorescence from the base of the pseudobulb, and bears about twenty-four 
flowers on each of its somewhat loose racemes. The sepals and petals are of a very 
light ochre yellow, the lateral lobes of the lip being marked with numerous collateral 
longitudinal broad dark-coloured and white stripes, and the front lobe on the same 
light-coloured ground, bearing a crescent-shaped half ring of dark brown. This 
Bornean species blooms during summer and flowers in succession, all down the spike. 
This species will thrive with the same treatment as C. Massangeana, that is, 
it may be grown either in a pot or in a basket suspended from the roof of the 
Orchid-house, using as a compost rough fibrous peat and sphagnum moss, and being 
careful to secure good drainage. A liberal supply of water must be given during 
the period of vigorous growth, and a smaller quantity during the season of rest. 
The plants are free in blooming if they are well cultivated and _ receive proper 
attention, which is simply to have plenty of light, and to be furnished with good 
Sweet material to grow in. They will do either in the East India house or in the 
warmest part of the Cattleya house, with a slight shading during the time the sun 
is powerful. The foliage frequently gets spoiled through having too much sun; a 
little of the early morning sun will not harm it, neither will it suffer after four 
o'clock in the afternoon when the heat is on the decline; but the hot midday 
sun is more than it can bear,
