THE ORCHID REVIEW. 43 
having formed a fraction of this compost also, but on the whole it seems to 
me to encourage growth from several points, these growths taking longer to 
develop, and probably flowering together, losing vigour, perhaps, a little 
afterwards. 
A rather large plant of C. x Sallieri in my possession, in the compost of 
which some Jadoo fibre was at one time mixed (though I do not think any is 
now present), also made luxuriant growth, and has four flowering growths 
this year.- It has also given me two batches of seedlings (in 1897, X 
venustum, and in 1898, X Leeanum Masereelianum), and is now bearing a 
pod (X Spicerianum). Perhaps this has told upon it, for I notice that 
there are many white streaks along the leaves : and seedlings from the cross 
between this plant and C. venustum (both as pollen and seed parent) have 
a similar anemic tendency, the worst affected making very poor progress. 
Whether this is in any way attributable to the original Jadoo it is difficult 
to say, none of the seedlings having been grown in any, but possibly they, 
as well as the old plant, want a stronger compost than they now have. 
Perhaps one of your readers could suggest some remedy for this anemic 
condition, 
Whatever the oe value of such a material as Jadoo fibre may 
Prove to be as a constituent of a compost for Cypripediums, there seems no 
doubt that: plants so treated can do for much longer in a comparatively , 
small receptacle, and with less water. But still over-watering is more 
dangerous. On the other hand, the compost should never be allowed to get 
really dry. I have not as yet noticed that young seedlings derive any 
advantage from its use—rather the reverse. I have not experimented on 
Pseudobulbous Orchids with Jadoo, but was told by a gardener from 
Messrs. R, Veitch, of Exeter, that a Cattleya labiata had done well in it for 
Some time. I should scarcely like to try it myself on any Cattleya, unless 
it were a very common and poor plant that I should not mind losing. _ 
On page 486 of Linden’s Les Orchidées Exotiques 1 observe that, speaking 
of the effect of the climate of the Equator on the culture of Orchids from 
other regions, he quotes Mr. Rand, of Para, who describes Phalznopsis 
Schilleriana as making long spikes, which, though they form bracts from 
which buds should issue, produce no flowers, but, after a time, at the end ot 
each stalk or ramification, a leaf is developed, and gives birth to a new 
plant. He had thus thirty plants on one stalk.

[In connection with the effect of climate, see the note on Mr. Rand’s 
specimen of Aérides odoratum (ante, vi., p- 274): At Para it grew 
vigorously for years, but never flowered, but since it was brought to 
England it has flowered freely each year.—ED. |
