216 THE ORCHID REVIEW. [JuLY, 1922. 
novel method, and one that is worthy of being used more extensively, was 
seen last year in an amateur’s house in the south of England. Coarse 
tiffany material, such as might be used for shading, was suspended along 
the edge of the staging, and when saturated with water kept the atmosphere 
continually moist. Each morning, and often again at mid-day, the watering 
pot was used to moisten this material, for with the ventilators under the 
staging wide open there was a constant current of air, and evaporation took 
place rapidly. Old sacking might be similarly used. When the door of a 
cool house opens into a corridor there is often an opportunity for ventilating 
the house by leaving it open, so long as the atmosphere in the corridor is 
fairly cool and moist. But when the door opens directly to the outside it is 
not advisable to allow the hot dry air of a sunny day to blow directly 
on to such plants as Odontoglossums, and an excellent preventitive 
measure is to make a light frame of similar size to the doorway and 
cover it with coarse tiffany or other canvas material which can be moistened 
as occasions arise. 
MAXILLARIA TENUIFOLIA.—This plant flowered for the first time under 
cultivation in the Horticultural Society’s garden at Chiswick, having -been 
sent there by Hartweg, who discovered it in 1837 in the vicinity of Vera 
Cruz. The ascending rhizomes carry pseudobulbs at intervals of about an 
inch. The flowers are deep sanguineous red to beyond the middle, the 
apical area yellow with leopard-like red-purple spots. In the Burford 
Lodge variety the flowers are yellow spotted with red, the spots on the 
petals and lip larger and deeper than those on the sepa!s.

CaTTLEYA TiTyus.—When this hybrid was first flowered by Messrs. 
Charlesworth & Co. in 1912 it was immediately accepted not only as an 
elegant result, but as a plant that would prove of considerable utility. 
The ten years that have since elapsed have more than proved this prophecy. 
An analysis of the two parents shows that in C. Enid (Mossiz X 
Warscewiczii) and C. Octave Doin (aurea x Mendelii), four well-known 
Species are included, all of which are individually beautiful and highly 
esteemed. Among the hybridists who realised at an early date that C. 
Tityus would prove to be a fine parent were Messrs. Flory & Black, and 
three of the new hybrids recently raised by them are descendants of it. 
The best, so far flowered, is Cattleya Dr. M. Lacroze (Octave Doin xX 
Tityus), of excellent form and substance, the sepals and petals unusually 
dark, and the large round labellum of rich purple. Two other promising 
hybrids are Cattleya G. P. Walker (Mendelii X Tityus), and C. Heather- 
wood (Mossiz x Tityus).
