330 THE ORCHID REVIEW. [NoVEMBER, 1914. 
The species was then lost sight of for a long period, but in rgrra plant 
flowered in the establishment of Messrs. Charlesworth & Co., Haywards 
Heath, which they had obtained from the Cattleya Dowiana district, and 
was identified as the missing plant (O.R., xix. p. 271). Soon afterwards it 
was exhibited at a meeting of the R.H.S. bearing a fine inflorescence of 
seven flowers, and received an Award of Merit (Gard. Chron., IQII, il. p. 
177, fig. 84). A year later Messrs. Charlesworth also exhibited a fine plant 
bearing four spikes of flowers (O.R., xx. p. 288). H. Wallisii is a distinct 
and striking species, and bears erect spikes of deep buff-yellow flowers, with 
numerous red-brown blotches on the sepals and petals, and in some cases a 
blackish red blotch on the base of the lip. Its re-appearance is interesting.

7 CALENDAR OF OPERATIONS FOR NOVEMBER. H 
Hybridising Department. 
URING the month of November the temperatures should be the same 
as advised in our last issue, and little change will be necessary in 
regard to watering, ventilation, &c. A sharp eye, however, must be kept 
on the stoker, or extremes in temperature are sure to occur. A dry, desert- 
like atmosphere, which is caused by excessive fire-heat, must be prevented, 
while a low temperature when the houses are heavily charged with moisture 
should also be avoided. 
Focs.—We expect dull weather at this period of the year, with perhaps 
an occasional fog, which does irreparable damage to the flowers of 
Dendrobiums, Lelia anceps, and especially to Calanthes, while even the 
foliage suffers where collections are near large cities. When foggy weather 
occurs all the ventilators must be closed, and the temperatures should be 
kept normal. This will enable the grower to do the usual damping down, 
and thereby help to keep out the fog. When the visitation has passed, the 
outside glass must be washed, also any of the plants that need it. Slight 
frosts may also be expected, particularly in northern districts, and where 
lath-roller blinds are employed they will be very helpful in keeping the 
temperatures even, and in saving fuel. 
PLEIONES.—At this season very few Orchids need attention so far a5 
repotting is concerned, but the Pleiones, such as maculata, lagenaria, and 
Wallichiana, which will soon pass the flowering stage, may be repotted. 
The flowers are produced with the new growths, and as soon as the flowers 
are removed a batch of new roots is produced at the base of the 
growths. Shallow pans are the most useful receptacles, which should
