THE ORCHID REVIEW. 183 
keep under at all costs. This department is still very gay. Odontoglossums 
crispum and O. Pescatorei are now seen to the best advantage. As a ser- 
viceable and showy Orchid the first-named can never be beaten, and small 
wonder that it is such a general favourite and grown in such enormous 
quantities. Nothing can possibly look nicer than a house full of this species 
in bloom, as they are at the present time, intermixed with a few O. 
polyxanthum, O. Hallii, O. luteopurpureum, O. x elegans, O. X Coradinei, 
and other yellow and chocolate-coloured species in their ever-varying hues 
and degrees of brightness. The culture of the whole of the above is of the 
simplest character. They require repotting about once in every two years 
—they may go as long as three—but should be top-dressed annually. The 
compost should be of the usual peat and moss, and the potting done some- 
what firmly. They like plenty of water during the summer, but should not 
be continually saturated. If treated in such a way, with free ventilation, 
they cannot fail to grow. But as I have said before, one thing is most 
particular, and must be strictly observed, namely, repotting them when in 
the right condition, which is when the new growths are one or two inches 
long. This may be at any time from now until the autumn months. 
Oncidium Marshallianum, O. concolor, and O. olivaceum (cucullatum) 
are others now in flower. They are best grown in pans or baskets and 
suspended, otherwise the culture required is similar in every respect to 
other cool Orchids. Oncidium candidum, sometimes called Palumbina 
candida, is now pushing its flower spikes. This species, like O. cheiro- 
phorum, a pretty little thing that flowers in autumn, does best under pan 
or basket culture. They grow well in the Cool house for the summer, but 
are better for intermediate treatment in winter. 
Lycastes are now growing apace, and if they are to be repotted should 
be done at once. They like a rather more substantial compost. The peat, 
therefore, need not be of the best quality, or a little fibrous loam can be 
mixed in. Lycastes are also better in the Intermediate house during 
winter, though they will stand a low degree of temperature if not over- 
watered. They are frequently lost through being kept too wet, especially 
L. Skinneri, which even when in full growth should be watered carefully. 
L. aromatica, L. cruenta, and L. Deppei, having been well rested since 
their last pseudobulbs were completed, are now producing a quantity of 
flower buds from their base. The new growths also appear from there 
simultaneously, and when these are seen they should be repotted, or they 
may be left over until the flowers have faded. If the latter course is 
adopted the new growths and roots will have grown very much in the 
interval, consequently the check will be greater. Bifrenaria Harrisonie 
(Lycaste Harrisoniz) is a very pretty old Orchid, and requires about the 
same treatment and warmth as for the Lycastes in general. It is not a
