62 THE ORCHID REVIEW. [ FEBRUARY, 1907. 
derived from P. x Sallieri Hyeanum x Spicerianum, and two forms of 
P. x Leeanum. There is also a very good form of P. X Charlesianum. 
Flowers of two very beautiful hybrids have been sent from the collection 
of Major G. L. Holford, Westonbirt, Tetbury, by Mr. Alexander. Leelio- 
cattleya Ariel was derived from Lelia Cowanii and Cattleya Dowiana aurea, 
and clearly shows its origin, as the sepals and petals are under two inches 
long, and very deep yellow in colour, while the lip is three-lobed, and orange- 
crimson with yellow veining on the disc. It isa gem, and Mr. Alexander 
considers it by far the best of the L. Cowanii hybrids. Paphiopedilum xX 
Moloch, derived from P. x Euryades and P. Charlesworthii, is also very 
beautiful. The centre of the dorsal sepal is rose-purple, and the broad 
margin white, with some rose-purple blotching at the sides. The lip and 
petals are of the Charlesworthii type, the latter being rather longer, and the 
staminode white with a yellow tooth. Both were exhibited at the R.H.S. 
meeting on January 22nd, last.

ODONTOGLOSSUM LEAVES DECAYING AT THE TIP. 
A CORRESPONDENT sends us examples of some Odontoglossum leaves which 
are decaying at the tip, and asks us to suggest the cause and a possible 
remedy. He remarks :—‘‘ The tips of the new leaves begin to turn brown, 
and if they are not cut off the whole leaf is soon lost. I know that is 
nothing unusual for Odontos to get tipped in this way, and when I was at 
one of the nurseries it was taken as a matter of course, but it disfigures the 
plants. It does not seem to attack weak plants more than strong ones, aS 
some of our strong plants suffer most. The house is kept well ventilated 
and only during frosty weather are the bottom ventilators closed, and we 
are able to keep a steady temperature, the lowest reading during this winter 
being 40 degrees, but our usual night temperature is about 45. It might be 
suggested that the house is too moist for the time of year, but since'I first 
noticed the tipping some weeks ago I have kept the house drier, but that 
seems to have no effect, indeed I believe it has spread worse than before. 
In the case of O. crispum it attacks the tips, and gradually works down, 
but in a leaf of O. Harryanum which I enclose it has attacked the leaf in 
the form of spots. I should be EY grateful if anyone can suggest a 
remedy.” 
We cannot detect any trace of fungus, and we are inclined to think the. 
disease commences with a chill, owing to the presence of too much moisture 
with a falling temperature, as it occurs chiefly we believe during the winter. 
The full effects would not be seen immediately. We should be glad to 
know the experience of other correspondents.
