20 THE ORCHID REVIEW. [JANUARY, I913- 
Pescatorei, and Wilckeanum will be in flower, and some throwing up spikes, 
whilst others will be at rest. 
OncipiumMs.—Most of the species of this genus will be in flower, notably 
crispum, Forbesii, incurvum, tigrinum, and varicosum. When they have 
finished blooming, stand them on the elevated shelf. 
CyMBIDIUMS.—Several members of this handsome genus will be in 
flower, notably insigne, Tracyanum, and Winnianum. Lowianum will 
probably be in full growth, and should receive weak liquid manure twice a 
week. : 
CyPRIPEDIUMS.—Undoubtedly many of these will be in full bloom, and 
it is largely in those winter-blooming varieties that the utility of this genus 
lies. C.aureum, Boxalli, insigne, exul, Hitchinsiz, Leeanum, Spicerianum, 
and villosum are invaluable. 
GENERAL REMARKS. 
Little needs to be done in an Orchid house this month. It is too early 
to repot any plant, and top-dressing should not yet be performed, and, 
therefore, the chief operations consist in maintaining a damp atmosphere, 
the correct degree of warmth, and in watering carefully. Damp the staging, 
pipes, and path, twice a day if fine weather prevails, if otherwise once at 
midday will be sufficient. An average temperature of 45°-50° Fahr. should 
be maintained at night, with an optional rise of five degrees during the day, 
or a little more with sun heat. 
For a beginner the following rules are suggested with regard to watering 
for this month: Growing plants, a good dose every other day. Flowering 
plants, in fine weather once a day, on cold, sunless days, every alternate 
day.. To all which are resting once a week will be found ample. With 
respect to watering, there are a few facts which should be clearly impressed 
upon the beginner: Should the temperature of the house fall below 45° 
Fahr. do not water any plants until it has risen to the correct figure. When 
applying water to any Orchid a good dose should be given, sufficient, in 
fact, to thoroughly wet the whole compost, not a mere sprinkling on the 
surface. Rain water, which in winter should be tepid, should always be 
employed. Admit as much air as possible, but do not ventilate if the 
thermometer stands below 48° Fahr. 
Generally, during the middle of the day, a fair amount of air can be 
admitted, but close the ventilators as soon as the temperature is liable 
to fall below the prescribed degree. No shading is needed this month. 
Group all plants which are at rest at the cooler end of the house. Here 
they will remain inactive for a greater length of time than if placed at the 
warmer end, and no mistakes need be made with regard to their watering. 
Next month I shall hope to dwell at greater length on the important 
subject of ventilation.
