“334 THE ORCHID REVIEW. [NOVEMBER, 1907 
_arose from the fact that the plants were grown much too hot, and they then 
soon took on a very sickly appearance. Water was also withheld to a great 
extent, and thrip soon got master of the situation, and consequently the 
plant soon ended its career. This trouble all arose in the first place through 
the plant being placed in a too hot and stuffy house. Here we never allow 
the plants to become really dry. They are grown in the Cool intermediate 
house, where much air is given on all favourable occasions. They are 
potted in a mixture of equal parts of peat and sphagnum, with plenty of 
-small crocks and coarse sand, and potting may be done whenever the plant 
is throwing up new growths. During the greater part of the year they are 
ikept well sprayed over. When treated thus I do not think they will prove 
-at all difficult to grow, and I think in the near future it will be found in 
most collections of note. 
PESCATOREAS AND ALLIES. — Pescatorea cerina and Klabochorum, 
-with Warscewiczella Wendlandii, Wailesianum, and others of the bulbless 
allies of Zygopetalum, require very similar treatment to the Chondrorhyncha, 
except that they require a rather warmer situation, such as a corner 
in the Intermediate house. They have been branded as bad growers, 
but I see no reason why they should not be successfully grown, providing 
‘they are not placed in a hot and stuffy house. They are moisture-loving 
plants, and during the brighter parts of the year much good will be done 
by frequent overhead-spraying: At this season this cannot be done much, 
but they can be aided by keeping the surroundings well charged with 
moisture, and on a bright morning a spraying overhead will not do any 
harm. Potting may be done when new growths are starting, using the 
same compost as given to Chondrorhyncha. I would always advise using 
-ordinary pots, or deep pans without side perforations. 
ZYGOPETALUM ROSTRATUM.—This beautiful and now somewhat rare 
species is grown with those previously mentioned, and treated much in the 
‘same way, with the one exception that we keep them rather drier after the 
flowering period is over, and the new bulb is completed, till the new growths 
start away again. 
PROMEN#A XANTHINA AND STAPELIOIDES.—These are two beautiful 
though small varieties, which are now fast finishing up their new bulbs. 
‘When full development has been obtained, the supply of water should be 
reduced until they start away into growth again, but on no account allow 
them to suffer for want of water. They grow very well suspended in the 
Cool intermediate house, and when in active growth they need much water. 
Shallow, well-drained pans are the best receptacles, using the same compost 
as for the foregoing species. The best season for renovating the surface OF 
ipotting is just when the new growths are nicely away.
