360 THE ORCHID REVIEW. [ DECEMBER, 1908. 
hybrids which may be pushing up their flowers, will need water oftener than 
those that are still resting. These are better staged by themselves, and then 
they do not get overlooked when watering. When these plants are in flower 
and several different mixtures have been used as a potting compost, notes 
should be made in comparing the flowers as to which have most substance, 
and last longest, as I think that good flowers are of far more value than 
sappy bulbs. Some mixtures give fine bulbs but inferior flowers. I find the 
most satisfactory way is to compare the flowers, as it is a much better guide 
to work on for next season. In making comparisons this year we find that 
the fibre mixture produces the finest flowers. A leaf mixture makes good 
bulbs but inferior flowers. I do not mean to say that leaves should be 
altogether discarded when such a result is found, but more fibre will need 
to be added next season in order to see what result we get then. 
Foas this year have so far been very scarce, here at any rate, and it has 
given us a better chance to prove our Cattleya flowers from different 
mixtures. 
So long as the weather keeps open plenty of moisture should be kept 
going in the houses, as it encourages plants to root, so long as a stagnant 
atmosphere is not created. A little air every day will prevent this, and if 
given with care and not just put on and taken off when one happens. to 
remember it, the plants will benefit by it. 
TEMPERATURES for the next few weeks should be kept about as advised 
in last month’s Calendar, and care should be taken to keep them as even as 
possible. Violent fluctuations are very detrimental to the health of the 
plants. 
PLEUROTHALLIS LEPTOTIFOLIA. 
IMAGINE a tiny Leptotes with a creeping rhizome, leaves reduced to under 
three-quarters of an inch long, and very slender scapes, twice as high as 
the leaves, bearing two or three yellow Pleuroth 
of an inch long, and you have this curious lit 
flowered with Mr. H, A. Tracy, 
with or taken off something else, 
succeeded in identifying it. Itis a native of Brazil, and was described by 
Babosa Rodrigues in 1877 (Gen. et Sp. Orch. nov., i. p- 15), from materials 
collected in the province of Minas Geraes. Then it appeared in cultivation 
d was figured by Dr. Kranzlin 
and afterwards it was collected in the 
ate » by Dr. Glaziou, and in one or two other 
localities. The short terete leaves and creeping habit give it a very curious 
appearance, and out of flower no one, without previous knowledge, would 
suspect it to be a Pleurothallis, A. R 
allis-like flowers, a quarter 
tle species, which has just 
at Twickenham. It had been imported 
and the record had been lost, but I soon.
