214 THE ORCHID REVIEW. 
grande is in full growth, and must not suffer for want of water. O. 
Schlieperianum is in flower, and will soon commence to grow. Another 
good thing belonging to this group is also flowering, and puts the latter 
quite in the shade. It is Odontoglossum Williamsianum, and, I think, is 
rather uncommon in‘cultivation. It bears a large and many-flowered spike 
of large and well-shaped flowers, and may probably be a natural hybrid 
between O. grande and O. Schlieperianum. Would that it were more 
plentiful. Plants of O. citrosmum are also growing fast, and those that 
were potted last year are finding the advantage this. We must expect 
those that have recently been disturbed to make smaller pseudobulbs the 
same year, and this remark applies to many other Orchids. If Ada 
aurantiaca, Cymbidiums, &c., require repotting, they should be done at once. 
Former experiences with Odontoglossum cirrhosum gave what seemed to 
me direct proof that the Intermediate house was the best place for it, and 
since then I have always grown it there. Last year, however, I placed a 
small plant in the coolest house for another trial, and, strange to say, it has 
grown, if not better, equally as well. Towards the end of this month will 
see our stock of Miltonia vexillaria done. They always grow best and are 
less liable to sudden collapse if kept in rather small pots. Water very 
carefully after repotting. Dendrobium amcenum, D. Falconeri, and D. 
cymbidioides are grown in this house. The first-named is now in bloom, 
the flowers being small but sweetly delicate and pretty. All the Coelogynes 
greatly appreciate being very near the glass, so as to get plenty of light. C. 
cristata delights to be in the sun, and being now growing strongly, is assisted 
by waterings of weak liquid manure. Lycaste Skinneri is also assisted by 
the same means. This last-named species is easily injured by getting it 
too wet at the roots; even when growing great care should be exercised. 
THE DENpRoBIUM House is now continually kept very warm and moist, 
and everything is done that will assist in promoting free, healthy, and 
strong growth. We meet with fair success with most species, but when 
compared with those grown in Cheltenham we are obliged to take a back 
seat. I notice in the D. nobile section this year a greater tendency for the 
foliage to become marked with black spots than they have ever done before. 
I can attribute this to nothing else but the severe winter through which 
we have passed, preceded by a dull and comparatively sunless summer. 
It would be interesting to know if this spot is general elsewhere ; and 
should these lines meet the eye of Mr. James Cypher, of Cheltenham, he 
would oblige many readers, as well as myself, if he would kindly say if it is 
so with him. The Calanthes are now getting nicely rooted, and may 
receive a little weak liquid cow-dung manure. Keep a sharp look out for 
red spider in this house. Roll up the blinds about 4 o'clock, thoroughly 
damping down at the same time. During cool nights employ a little 
artificial warmth. Some of the Thunias will, by this time, have finished
