THE ORCHID REVIEW. es 
the list of first favourites, yet where room can be found for them a few 
_ members of the genus should be grown for the sake of their peculiar, 
wax-like flowers. They should be grown in shallow baskets without any 
crocks or other hard substances at the bottom, as the scapes usually take a 
downward course, and oftentimes go straight down through the basket. A 
small portion of good peat and moss is all that is needed for them to root 
into, and excepting when in full growth very little moisture is required 
other than that obtained from the air. Those whose baskets have become 
rotten, or too small, may b2 given new ones this month. They do best 
when suspended from the roof of the Cattleya house. An item of vital 
importance to the young growths is never to let water lodge in the young 
unfolded leaves, or the probability is they will damp off. 
Diacium bicornutum was long known under the name of Epidendrum 
bicornutum, and of all the Epidendrums at present under cultivation, it 
will be generally admitted that none surpass it in beauty, though from a 
cultural point of view it is far from satisfactory, as it almost holds the 
record of being the worst grower of the lot. It has cylindrical bulbs, 
which, strange to say, are hollow, like those of Schomburgkia tibicinis, and 
on this account will not stand a long period of drought. Having flowered 
during the last month, a short period of inactivity should ensue prior to new 
growths appearing. When these appear the plants should have all the old moss 
picked out and replaced with new. This species thrives best in baskets al- 
most filled with crocks, and just surfaced with moss. The baskets should 
be suspended in the warmest and lightest structure at command, and during 
the growing season deluged with water daily. As soon, however, as the 
growths are completed, a gradual lessening of the supply should follow, 
though, as stated above, they should not be kept dry for long together, or 
the bulbs will shrivel beyond recovery. 
ODONTOGLOSSUMS FROM KELVINSIDE. 
A SERIES of very beautiful Odontoglossums has been sent from the 
collection of Hugh Steven, Esq., Westmount, Kelvinside, Glasgow, by Mr. 
D. Wilson, affording evidence of excellent culture. Single flowers of over 
a dozen forms of O. crispum are included, showing the wide range of 
Variation met with in this beautiful species. Several forms have quite 
unspotted sepals and petals, ranging from pure white to light rose, some of 
them only flushed with very light rose in the sepals, but nearly all having a 
few small or larger spots in the lip. Two or three others have a few or 
several spots or blotches on the sepals, but the petals unspotted, while the
