5° THE ORCHID REVIEW. [FEBRUARY, 1923- 
While in the genus Cypripedium it is the dorsal sepal that is prominently 
developed, just the reverse takes place in Restrepia maculata, for, as may 
be seen in the accompanying figure, this segment is represented by an 
almost thread-like organ (S). The two 
lateral sepals cohere almost to their 
extremities, and form the chief attractive 
feature of this and other species of the 
genus. It is a similar example of the 
manner in which the lateral sepals 
cohere in Cypripediums, although in 
this latter genus the cohesion is con- 
tinued to the extreme points, and no 
V-shaped opening occurs. 
Although Disas are not generally 
represented in collections by more than 
a very few species, D. grandiflora being 
that most usually seen, one little point 
RESTREPIA MACULA 
concerning them is worthy of note. The _ with thread-tike upper and sass and broad 
coherent paset sepals. 
flowers possess a hood-shaped segment 
that is oftentimes erroneously spoken of by amateurs as the labellum, but 
which is, in fact, the upper or dorsal sepal; by its frequently large size and 
formation it seems to fulfil the part played by the labellum of other Orchids. 
The real labellum in Disas is an organ of comparative insignificance.

PHOLIDoTAs.—Though allied to Ccelogyne and requiring similar culture, 
horticulturally the plants. included in this genus have not so much to 
recommend them. The flowers are of small size, though freely produced, 
and are carried in terminal racemes, each flower being partly hidden by an 
overlapping bract. The plants have either decided pseudobulbs on creeping 
rhizomes, or ascending articulated stems with fleshy joints. P. articulata, 
conchoidea and imbricata are the three species generally met with.—Sanders’ 
Orchid Guide. 
EULOPHIA GUINEENSIS.—This species, perhaps the best known of the 
genus, was introduced from Sierra Leone, in 1821, by George Don, when 
collecting for the Horticultural Society of London, in whose garden at 
Chiswick it first flowered during the following year. It was successfully 
cultivated in the Burford Lodge collection by using a compost composed of 
fibre, moss and broken crocks. During the growing season it was kept in 
the East Indian house with liberal supplies of water, but when in flower a 
more airy and cooler atmosphere was.selected.
