THE ORCHID REVIEW . |Septe 
plants, especially those that have been divided. Undisturbed plants will 
need a liberal supply of water during the growing season, and an 
occasional dose of weak farmyard manure will benefit them. In the case 
of large specimen plants, some of the old growths that have flowered should 
be removed, severing them close to the roots, thus allowing the young 
growths that are forming additional room to develop, and at the same time 
admitting light and air to them. The leaves are subject to attacks of red 
spider and thrips, but if the syringe is used freely under and over the foliage 
on fine days little difficulty will be found in keeping these pests in check. 
Sobralias thrive best in a cool, intermediate temperature, with plenty of sun¬ 
light and fresh air at all times to enable the plants to form strong healthy 
reeds that will flower satisfactorily. 
Gcelogyne cristata.— Healthy established plants of this species and 
its varieties will require copious supplies of water at the roots until the 
pseudo-bulbs have completed their growths, and weak farmyard manure 
applied occasionally will prove beneficial. Plants newly potted this year 
need clear water only, and watering must not be overdone as the new 
material is very retentive of moisture, and too much water would sour the soil. 
The plants will be all the better if they are grown well up to the light, and 
with a free circulation of air about them, thus ensuring good, hard pseudo¬ 
bulbs. 
Pleiones. —These will be finishing their season’s growth, and as the 
leaves decay, scarcely any water will be needed at the roots, although the 
potting material should not be allowed to become dust dry, but kept just 
moist until the flowering season is past. 
Lycastes. —These should now be treated liberally, as the plants 
generally are forming their bulbs and rooting freely at the same time. 
Anguloas should be treated likewise, until such time as they show signs of 
losing their leaves, when the supply of water to them, and also to the 
deciduous section of Lycastes, should be gradually diminished. Others of 
the genus that retain their foliage should, after the growths are complete, be 
given less water, but they must not be allowed to remain dry at the roots 
for any length of time. 
Caladenia Doutchab. —This new species is described in the Journal of 
Botany, 1921, p. 175, by Mr. Oswald H. Sargent, who states :—“ This closely 
resembles C. Roei, Benth., from which it is readily distinguished by its 
definitely caudate sepals and purple-veined labellum with extremely small 
and slender calli. I have named it in honour of Miss L. Doutch, from 
whom I received it in September, 1919. She was in charge of the State 
School at Datatine near Katanning, and the species was collected not far 
from the school.”
