42 THE ORCHID REVIEW. 
recorded as tropical valleys up to 3500 feet, and its whole distribution 
suggests that it requires rather more heat than its allies, especially during 
the cooler half of the year. For hybridising purposes it has proved most 
useful, having participated in the parentage of some of the finest hybrids 
yet raised. 
ADVENTITIOUS GROWTHS ON ORCHIDS. 
I NoTICE in the OrcHip REVIEW for December last (p. 357) a note by Mr. 
Ross on a supposed seedling growing from the very base of a seed-pod, and 
your remarks thereon. I have very little doubt that it is a growth in place 
of what might have been a bud, and analogous to the aérial growths of 
Dendrobiums and other Orchids. 
In the article which you were kind enough to insert under the heading 
of ‘“‘An Amateur’s Experiences” in the volume for 1898, I mentioned 
(page 163) that before ripening of a pod ona small plant of Cypripedium 
x Leeanum superbum, a little growth was produced, immediately below the 
pod, from the point whence another bud might have developed had there 
been a succession of flowers on the same spike. In* faet, the first leaf 
produced had the appearance of a small, deformed dorsal sepal. From the 
base of this (which almost immediately died off) another little green leaf 
commenced to grow, just as in a seedling, but rather broader, and in time 
another little one commenced to show. At about this stage the seed pod 
above it ripened, and the stalk below the little growth began to wither, and 
one morning I found the latter fallen on the surface of the compost in the 
pot. It looked so fresh, and the base of it appeared so firm, though as yet 
pushing no root, that I was tempted to treat it as if it were a seedling, and 
potted it up. No change occurred for some time, though it kept its fresh 
appearance. After a few months, however, I observed that it was com- 
mencing new leaf growth, and emitting a little root. It continued to grow 
slightly, but none of the leaves yet made have been so big as the first made 
on the plant stalk, and which has since rotted off. It has evidently a poor 
constitution, and now looks like a small seedling about six months old. 
{ have not heard of a parallel case in Cypripediums, though, of course, 
aérial growths in pseudobulbous Orchids with many joints are common. 
I am under the impression that the cause of this unusual growth might 
be the presence of some Jadoo fibre in the compost. The plant has not 
required re-potting (until quite recently) since 1897, but it has continued to: 
increase its growth and seems very healthy, though it has not been at all 
floriferous. It has just expanded one fine flower, the first since 1897- 
Another C. x Leaanum now propucing two flower buds (and which did the 
same as last year) has not been repotted for a considerable time, Jadoo
