a42 THE ORCHID REVIEW. | May, 1903. 
‘Cymbidiums do not appreciate dryness, either at the root or in the atmos- 
phere, as it will cause loss of foliage, greatly to the disfigurement of the 
iplants. The above remarks also apply to C. elegans, C. Mastersii, 
C. affine, C. aloifolium, C. ensifolium, C. chloranthum, and. C. 
‘longifolium. C. Lowianum does not require such a large amount of pot 
iroom as C, eburneum, and when properly potted and looked after may 
‘remain undisturbed for many years, and will produce its long arching spikes 
‘more freely when kept ina pot-bound condition. An occasional dose of 
‘weak liquid manure will greatly benefit the plants when throwing up their 
flower spikes. C. giganteum, C. pendulum, and C. Hookerianum may be 
treated as advised for C. Lowianum. C. Devonianum produces its 
‘pendulous racemes from the base of the young growths, and should be 
grown in a basket suspended. All these Cymbidiums may be grown well 
-along with C. eburneum. 
Pleiones are now growing freely, being suspended in a sunny position in 
‘intermediate temperature. They are fond of plenty of water at the root, 
-and should not be allowed to get dry; syringe them at least once a day. 
Sobralias are now showing for flower, and if at all pot-bound with roots will 
‘be helped by an occasional watering with weak liquid manure. The 
Anguloas will now be growing, and fast sending up their flowers, which, 
when fully developed, are both attractive and interesting. These plants 
may be re-potted either immediately they commence to grow, or when they 
shave done flowering. Anguloas are free rooting plants, hence they should 
have considerably more material to grow in than the majority of Orchids 
require. Fill the pots half way up with clean broken crocks, then cover the 
‘drainage with a layer of moss, using as a compost two parts peat, one good 
fibrous loam, and the remainder chopped sphagnum. During active 
growth, and until the bulbs are thoroughly matured, give plenty of water, 
and an occasional supply of weak liquid manure will be beneficial. When 
growth is completed, gradually diminish the supply of moisture at the root, 
_just enough being given to prevent undue shrivelling. 
DENDROBIUM WILLIAMSONI AND D. CARINIFERUM. 
DENDROBIUM WILLIAMSONI is a very imperfectly known species of the 
D. formosum group which has at last re-appeared -in cultivation. It was 
-described in 1869 (Gard. Chron., 1869, p. 78), from a specimen which 
flowered in the collection of the late John Day, Esq., of Tottenham. 
Reichenbach described it as an ally of D. Draconis, having ivory-white 
flowers, and bearing a ‘“‘grand three-lobed blood red spot ” on the iep. » It 
‘was sent from Assam by W. J. Williamson, Esq., Mr. Day’s nephew, with 
-other novelties. Then it was recognised (from description) among some
