52 THE ORCHID REVIEW. [ FEBRUARY, 1915, 
but as each'specimen becomes firmly re-established increased supplies may 
be given. Endeavours should always be made by cultivators to prevent 
injury to the new roots by insects, such as wood-lice and cockroaches, both 
of which do much harm by gnawing them and destroying their succulent 
points. Beetlecute will destroy large numbers of them, but baits should 
also be freely employed, such as apple and potato, which should be 
hollowed out in the centre, and frequently examined, particularly at night 
and early morning. Old well-established specimens should also be carefully 
examined soon after each watering, as oftentimes wood-lice may then be 
seen on the surface, and especially near to the base of the pseudobulbs. 
L2&LIOPSIS DOMINGENSIS.—This West Indian Orchid is still rare, and 
blooms at this season. _Its flowers are produced on long slender stems, in 
a similar manner to those of the better-known Lelia acuminata, and they 
measure about two inches across, the colours being pale rosy mauve with 
purple veins and markings. The plant requires similar treatment to the 
Mexican Leelias. : , | 
ODONTOGLOssUM CITROSMUM.—Suspended close to the roof glass in the 
same house as these Lzelias, plants of the distinct Mexican Odontoglossum 
citrosmum will be starting into growth, but they should not be disturbed by 
repotting now. The new growths should not be unduly excited, by heat or 
otherwise, to make a rapid advance, or they will start away and produce no 
Hower spikes at the proper season. Still keep the plants fairly on the dry 
side, but immediately the small white flower spike is seen pushing Up 
through the centre of the growth, then the plant may be allowed more 
generous treatment, both as regards atmospheric moisture and a consider 
able increase of water at the roots. 
CaTTLEYA WaLkERIANA,—In this house plants of Cattleya Walkerian@ 
are about to flower, and will require a little more water at the root. This 
distinct species produces its flower spikes from the apex of short lateral 
growths which issue from the last-made bulb, The plants should be suspended 
in a light position near to the roof glass. A similar position should be found 
for plants of C. O’Brieniana and its pure white variety alba. As these 
plants are now dormant, they should be kept comparatively dry at the root 
idl growth recommences, remembering that only a small amount of 
moisture Is needed to retain the pseudobulbs in a plump, fresh condition. 
EPIDENDRUM PARKINSONIANUM.—An interesting Orchid now flowering 
in this house is Epidendrum Parkinsonianum, a plant with very small 
a but with large fleshy leaves. Owing to the weight of the leaves the 
plant grows in a downward direction, Suspended as it were by its root 
The flowers, which are produced from the base of the leaves, are of a pale 
seed green, and the lip a good white. Like the allied’ E. ciliare, the 
Owers emit a strong sweet perfume at night. Its cultural requirements
