THE ORCHID WORLD. 
The cultivation of Orchids so far from their 
natural liahilais, and in a climate of such a 
variable character as ours, depends for its 
success not so much on how we can by arti- 
ficial means reproduce the conditions under 
which they grow wild — and in one house we 
may have plants growing side by side that 
grow wild thousands of miles apart — but how- 
best we can apply the ascertained facts of our 
experience with them here in our glass-houses. 
A rooting medium of a suitable physical tex- 
ture, and containing all the constituents of 
plant food ; water, heat, light and air, under- 
stood and co-ordinated, mean success, and all 
cultural directions must revolve round these. 
ODONTOGLOSSUM HARWOODII. 
This very fine variety of Odontoglossum 
was obtained by crossing O. Wiganianum and 
O. maculatum auriferum. The colour of the 
flower is a clear buttercup )-ellow, with a 
somewhat lighter shade m the centre of the 
sepals and petals, which are spotted with dark 
claret colour. O. Wiganianum is a hybrid 
between O. Rolfeae and O. harvengtense, the 
latter being the result of crossing O. crispum 
and O. triumphans. It is only by the most 
Odontoglossum Harwoodii. 
careful selection and study of the parents 
used that we obtain such wonderful results, 
and the work of the hybridist has now- 
advanced to a very high position lu the world 
oL art. This rare Odontoglossum received a 
First-class Certificate from the Orchid 
Committee of the Royal Horticultural Society 
when exhibited by Messrs. Charles vorth and 
Co., on January 31st, igii. G. \\'. 
Odontoglossum Janthe. 
ODONTOGLOSSUM lANTHE. 
Hallio-cnspum x ardentissimum. 
For perfection in form it would be difficult 
to improve upon the present subject. The 
massive segments of creamy yellowish-white 
are heavily and beautifully marked with 
blackish-tinted brown, which always seems to 
be the result of Hallii crosses so far as they 
have yet been raised ; and the fine oblong lip 
w ith \ ery high shoulders is another character- 
istic peculiar to Hallii, which has been often 
sneered at iis a parent. 
I would like to sa)' here, before more 
hybrids are raised from Hallio-crispum, that 
this original name must be adhered to and 
that it be not called Cooksonii, as there is a 
subsequent hxbrid named Cooksonianum 
derived from mirificum x crispum. Mr. 
Charlesworth has added a good thing, in 
lanthe, to his already immense number roll.
