ONCIDIUM PHALAENOPSIS. 
THE annexed figure of the beautiful Oncidium Phalznopsis is reproduced 
from a photograph kindly sent by Frau Ida Brandt, Reissbach, Zurich (gr° 
Mr. Schlecht), and gives an excellent idea of the species—if such it be. 
It is one of a group of forms allied to O. olivaceum—better known under 
its later name of O. cucullatum—and was described by Reichenbach in 
1869 (Gard. Chron., 1869, p. 416), from materials collected in Ecuador by 
Gustav Wallis, and sent to M. J. Linden, of Brussels. It has generally 
larger flowers than its allies, and the sepals and petals are more or less 
heavily barred with purple on a very light ground, while the lip is white, 
or slightly flushed with rose, with numerous purple spots round the crest. 
Fig. 26. ONCIDIUM PHALNOPSIS. 
Its characters are well shown in the illustration. Very little seems to bave 
been recorded about its exact habitat, though it is known to be a high 
alpine form, coming from an altitude of between 8,000 and 10,000 feet 
elevation, and consequently it requires to be grown in the coolest house. 
Even then it is by no means an easy plant to cultivate, for it grows naturally 
under conditions which can only be approximately imitated in our Orchid 
houses. It is certainly a very beautiful plant, and one of the most attractive 
in the genus when seen in anything like its native vigour, which is unfortun- 
ately too seldom.
