attention given, providing, of course, that proper houses and conveniences 
exist in which to grow them. __D. cruentum is now in flower, and is quaint 
and rather pretty, the sepals and petals being greenish white, whilst the lip 
is prettily marked with a bright chestnut red. 
Oncidium longipes, O. Schillerianum, and O. nigratum, are three pretty 
little species which are also now blooming. They are very free growing 
and require no exceptional treatment other than to be grown in the 
Intermediate house. The first-named is best suspended in pans or baskets. 
O. Schillerianum is noted for the great length of its thin wire-like spikes, 
which twine together when growing in a tangled mass, and when so is more 
showy and pretty when in bloom, as the flowers being small would look 
nothing if not so massed together by nature. O. nigratum is rather 
effective when the spikes are strong, the colour of the flowers reminding one 
of a miniature Odontoglossum cirrhosum. 
Oncidiums do not like being often disturbed at the roots, and this 
therefore should not be done without good cause. But when potting is 
necessary, give good and perfect drainage, and use good fibrous peat and 
sphagnum moss, taking every precaution that the watering is always 
carefully done, so that the compost lasts the longest possible time in good 
condition. 
GENERAL Remarks.—As the power of the sun declines see that the 
shading is gradually reduced and more air given, So that the plants may 
become well matured. Air during the autumn months can always be given 
more freely than at any other season. Go through the plants now, if 
possible, and sponge them, as this is a time of year when the various 
species of scale, &c., breed and increase very rapidly, and should be 
checked, as no plant can grow well if not kept clean. What Cattleya and 
Lelia potting is required should be done not later than this month. I 
mean the late summer-blooming kinds like C. Warscewiczii and C. 
Gaskelliana. If not done this month it is too late, and they are best held 
over until the following spring. 
SPOT ON DENDROBIUM LEAVES.

llections, and before 
With respect to the question mentioned at pag 
leaves being more spotted than usual this season, Mr. 
that he has observed the same thing in many CO ; 
reading Mr. Burberry’s notes had arrived at the same conclusions as to the 
Cause, namely the severe winter preceded by a comparatively dull and 
sunless summer. Mr. Elwes, of Colesborne, has observed the same thing 
in his Dendrobiums, and is at a loss how to account for it. It would 
therefore appear to be pretty general. We cannot suggest any amie cause 
for the mischief, but our knowedge of this disease is still very imperfect.
