SEPTEMBER, 1911.| THE ORCHID REVIEW. 259 
Among Odontoglossums and allied genera the rate of progress has been 
temarkable, and if one may judge by the thousands of unflowered seedlings 
in many of our great establishments it is likely to be maintained for a long 
time to come. What is wanted now is work along definite lines, and with 
some set purpose in view. A correspondent suggests that blotched Odonto- 
glossums have now become so numerous that more attention should be, 
given to the improvement of albino races, and in this connection we may 
mention the beautiful O. armainvillierense xanthotes as still one of the best, 
‘yet it might be possible to improve it by re-crossing it with the best albino 
<rispums. [Indeed we believe this has already been done, but a little time 
must elapse before the results can be seen. 
Hybridising Orchids is, after all, rather slow work, and one must not 
lose patience because the results are not immediately apparent. The chief 
thing one can do is to use only good parents, and avoid combining them in 
such a way as to neutralise their good qualities, and one can then fee! 
pretty sure that some satisfactory results will follow. The inferior forms 
¢an easily be discarded. 
DENDROBIUM LOWII AND D. DEAREI. 
AN interesting piece of information respecting the rare and_ beautiful 
Dendrobium Lowii has just come to hand. M. G. Poupardin, Ferrieres- 
en-Brie, Seine et Marne, France, sends the apex of a pseudobulb, with two 
flowers and leaves attached, remarking: ‘I send you a specimen of a 
Dendrobium which we found in a group of Dendrobium Dearei imported 
last year, but not having imported the plants ourselves I cannot give the 
exact locality.” The plant is Dendrobium Lowii, Lindl., and agrees 
exactly with the Botanical Magazine figure (t. 5303). Now D. Lowii is a 
native of Borneo and D. Dearei of the adjacent Philippine Islands, but this 
information suggests that somewhere the areas of the two species overlap, 
and it may therefore be interesting to trace their history. 
Dendrobium Lowii was originally described by Dr. Lindley about half 
a century ago (Gard. Chron., 1861, p. 1046), the author remarking: “A 
most attractive species, imported by Messrs. Low, of Clapton, from Borneo, 
and exhibited by them at a meeting of the Floral Committee of the 
Horticultural Society. Fragments of what appears to be the same plant 
occur among Mr. Motley’s Orchids (n. 201), gathered at Banjarmassing. 
The flowers are admirably beautiful, produced in dense racemes, as many as 
seven together, and are fully two inches in diameter, of a charming yellow 
colour, set off in a striking manner by six red lines on the lip, bearing long 
crimson fringes.” Shortly afterwards it was figured in the Botanical 
Magazine (t. 5303) as: “A splendid and remarkable new species,
