from 2 to 3 inches. On the drainage place the rougher portions of 
the compost, and fill up until there is sufficient room left for the 
base of the bulbs to be level with the rim of the pot. Put a small 
stake to each, so as to keep them steady until sufficiently advanced 
to take care of themselves. Remove to a temperature of from 
60® to 70°, and syringe frequently about the pots, 
taking care not to sour the soil before the roots 
have made some progress. 
When the thick fleshy roots can be discerned 
making their way into the new compost top-dress 
with a few good pieces of lumpy peat and loam, 
placing small lumps of sphagnum moss where 
available. When the top-dressing is completed 
the base of the bulbs should just be on a level 
with it. As the season advances copious supplies 
of water may be given, and to plump the bulbs 
up thoroughly apply weak liquid manure twice a 
week. When the winter approaches, and the 
bulbs seem to have stopped growing, water may 
be withheld altogether, for it is only by a thorough 
season of rest that this Orchid can be induced to 
flower, and it is just at this stage that so many 
failures occur through not withholding water 
from them. 
In early spring the flower spikes may be seen 
pushing from the base of the stronger pseudo- 
every year, in efficiently drained pots, using about equal parts good 
fibry peat and sphagnum moss with a few small potsherds and a 
little fine charcoal being added, making the whole quite firm and 
keeping the plants well up in the pots. 
The plants require plenty of heat and atmospheric moisture, 
and being kept uniformly moist at the roots 
during the growing period and until the indi¬ 
vidual growths have developed their last pair of 
leaves. They should then be suspended from 
the rafters in a dry airy house to mature their 
growth, water being gradually withheld from the 
roots. The temperature of a late vinery would 
suit the requirements of the plants admirably, 
first making sure that they are perfectly free 
from mealy bug before putting them in a vinery. 
The plants may be introduced into a warm house 
early in January for flowering in March.—

Cypripedium X Penelaus. 
One of the finest hybrid Cypripediums raised 
during the past year or two was that exhibited 
by Messrs. James Veitch & Sons at the meeting 
of the R.H S. on January 17th under the name 
of U. Penelaus. It was the result of a cross 
between the distinct variety of C. caudatum 
bulbs, and until these get far enough advanced to discern them 
from the growth there should be absolutely no more water given 
than what will prevent the plants shrivelling. By following this 
system of culture we are able to flower this delightful Orchid every 
season. White scale often attacks the foliage. Sponging with a 
little softsoap and water will soon remove it, but care should be 
used, so as not to damage the leaves.—R. P. R. 
Dendrorium Devonianum. 
Plants of this pretty deciduous Dendrobium growing in 4|-inch 
and 6-inch pots, and suspended from the roof, are very effective. 
One shoot of a plant I have has forty expanded flowers extending 
over a length of 2 feet. The flowers are very pretty, the sepals 
and petals being creamy white streaked with rosy purple, and 
the lip being white, beautifully fringed and edged with rosy purple, 
and having two orange spots, one on each side, at the base. The 
plants should be potted when finished flowering, not necessarily 
named Lindeni, with its long, peculiar lip, and the well-known- 
C. calurum, the former being the pollen and the latter the seed 
parent. Their union was a happy idea on the part of the 
hybridiser, for the result could hardly fail to be distinct and- 
interesting, if not beautiful. C. Penelaus is all three. One of 
the most remarkable features of a noteworthy flower is the lip,, 
which does not follow the peculiar structure of C. caudatum 
Lindeni, but is large, full and massive, in colour a bright greyish 
rose. The dorsal sepal is long, narrow, and pointed, greenish, 
yellow in hue. The petals are extremely beautiful ; they are long,, 
drooping and twisted, soft rosy pink in colour, and impart a most, 
graceful appearance to the flower. It will be gathered that th® 
colouring does not partake of the “ harmony in green and brown ” 
type, but rather classes it with the select number of richer coloured 
forms, of which 0. Sedeni candidulum is one of the most familiar 
examples. The new hybrid has, however, a much finer flower than 
that favourite Cypripede can boast. Fig. 45 represents it.
