nearly horizontal. The species was discovered by Ericsson, when collecting 
for Messrs. Sander & Sons, St. Albans, and was described by Dr. Kranzlin, 
in 1893 (Gard. Chron. 1893, ii. p. 522), the exact habitat not being recorded. 
Early in 1897 it flowered for the first time in cultivation, in the collection 
of the Hon. Walter Rothschild, at Tring Park, when it was figured 
(Gard. Chron. 1897, i. p. 61, fig. 16), and it was said to be probably a native 
of New Guinea. On March gth of that year it received a First-class 
Certificate from the R.H.S., and on November 18th, 1902, it was again 
exhibited from the same collection, and received a Botanical Certificate. It 
has recently been figured in the Botanical Magazine (t. 8088), from a plant 
which flowered in the collection of Sir Trevor Lawrence, in October, 1899, 
an observation of Mr. White being recorded that ‘‘the flowers close 
partially at night, and open again in the morning.” The individual 
flowers were originally compared with those of a Chimeroid Masdevallia, 
and recently they were described as “ arranged in acircle, with the dorsal 
sepals piled up in'the centre like a Chinese pagoda.” This appears to be 
the normal character, for a year earlier a plant was described as “ bearing 
an umbel of eight blooms, radiating like the spokes of a wheel, with the 
eight dorsal sepals piled up in a pyramid in the centre” (O.R. xiv. p. 270)- 
This character is not shown in the figures mentioned, which probably arose 
from displacement of the flowers when packed in a box to send to the artist- 
The ground colour of the sepals and petals is light green, and the markings 
dark brown, these taking the form of spots and transverse markings on the 
sepals, and of longitudinal stripes on the petals. The lip is broad, fleshy and 
recurved in front, and suffused and mottled with reddish purple on a 
whitish ground. The sepals are very acuminate, and it will be noticed that 
the lateral ones are curled in a spiral at the apex. The petals are only half 
as long as the sepals, but equally accuminate. The inflorescence as shown 
measured eight inches in diameter. The species is nearly allied to 
B. virescens, whose history was recently given (O.R. xii. p. 272), and is 
quite similar in habit, but differs in the spotted flowers.

CALENDAR OF OPERATIONS FOR AUGUST.

WATERING is always a very important detail in the management 
of Orchids, and, with the regular maintenance of a sweet and buoyant 
atmosphere, is one of the principal factors towards success. It does not 
matter how well a plant may have been potted, or how good the material 
used may have been ; if watering and ventilating are not done with great 
discretion, the highest ideal will not be attained. In commencing to write 
these remarks I had intended only speaking about watering, but the two
