370 THE ORCHID REVIEW. [DECEMBER, IQII- 
the rock as high as we could, I was obliged to get upon the shoulders of my 
companion M. Sonnerat, when, with a long stick, I beat down five of these 
plants, the only specimens that were then in bloom. M. Sonnerat, who 
before had not had an opportunity of collecting as many plants at the foot 
of the mountain as I had, made in this one day only a collection of 300 
different species, but was so singularly unfortunate, though he had brought 
with him three pairs of shoes for this excursion, as to return to town 
barefooted. . . . Your thin French pumps are by no means suited for 
excursions upon the mountains.” 3 ‘ 
Formerly the species was regarded as peculiar to Table Mountain, but 
latterly it has been discovered in the Stellenbosch Mountains. Unlike 
D. uniflora, it loses its leaves usually after flowering, and this would suggest 
a resting period in its culture. 
Cultivators on the look-out for novelties should endeavour to secure the 
albino form of D. uniflora, which has occurred spontaneously among the 
normal type on Table Mountain within recent years. The flowers are as 
large as in the normal form, but the colour is a pure sulphur yellow, 
without the faintest trace of red. 
CALENDAR OF OPERATIONS FOR DECEMBER.

WE have now arrived at the darkest and dullest part of the year as regards 
climatic conditions. The days are short and the nights long; therefore it 
is an absolute necessity that our plants should enjoy all the light possible to 
consolidate their growths, and that the glass of the various houses should be 
kept as clean as possible. In some localities this will require much more 
attention than in others ; in some cases it may require to be done outside 
every week, and in others, where they are entirely free from smoke, twice 
during the winter months will suffice, but in no case should the detail of 
light be neglected. 
TEMPERATURES should now be brought down to the winter figures— 
namely, those given in the January number. 
WATERING AND VENTILATION.—The remarks made last month as 
regards these two items should be strictly adhered to, as it is obvious that 
if the conditions of the various houses do not suit the inmates they must 
- suffer, just as we ourselves suffer when placed under unhealthy conditions. 
Pottinc.—Very few plants will now require re-potting, but if at all out of 
condition, do not hesitate toturnthem out. The only thing to guard against 
afterwards is over-watering. It is astonishing how soon a plant will push 
new roots into new compost if kept in a proper condition. It is always 
desirable at this season to keep a stock of the various fibres and other 
articles that go to make up the various composts, as often in the New
