THE ORCHID REVIEW. 235 
_’ Further in the interior and on trees on the lower range of hills are found 
D. longicornu and D. cariniferum. These two plants I never found in the 
hot plains, and they may be considered intermediate between the heat- 
loving Formosz and the mountain forms. These two varieties do not 
require to be grown in so much heat as the others, but they require more 
than the two special mountain forms, D. Jamesianum and D. infundibulum. 
In Veitch’s Manual, D. Jamesianum is considered a variety of D. 
infundibulum, but I never found them growing together on the same hills. 
Each variety is confined to its own range of mountains. “ Theobald,” in 
his remarks on the land*shells of Moulmein, remarks that each isolated 
group of hills has its own peculiar land shells, nearly allied to each other 
but quite distinct, and probably the same remark would equally apply to 
certain groups of Orchids. © 
‘On the very top of the range of mountains which can be seen from 
Moulmein, grows in abundance a short robust form of D. Jamesianum. It 
is found growing abundantly on the rocks and also on the trees. The 
flowers of this variety are very rich in colour, but the plants are dwarf and 
robust in habit, quite different from the variety found on the southern range 
of the Arracan hills, where the plants are found extremely abundant; and 
in habit quite four times the size of the Moulmein hill plants. 
D. infundibulum is found in the ranges of hills further away from 
Moulmein, and also in the north of Arracan far up the River Kuladan, in 
the hills which are probably the source of this river. There is no doubt 
that both D. Jamesianum and D. infundibulum require quite different 
treatment from the other forms. They are essentially mountain varieties; 
and they continue to grow throughout the winter, flowering abundantly in 
the spring. I have seen, in the Arracan hills, five hundred plants of the 
variety Jamesianum in flower at one time, forming a grand sight. So 
profusely do these plants flower in their native habitat, that the plants 
become much shrivelled, and should the heavy rains be delayed many of the 
plants die. | : 
I should say of these two varieties, judging from the conditions unde 
which they grow abroad, that they should be grown warm in winter and 
cool in summer in our houses at home, and I have experienced no difficulty 
in keeping them in good condition when treated in this way.. They are two 
of the most useful of the Formosz section, as they last such a long time in 
flower.

CYPRIPEDIUM x HARRISIANUM VIRESCENS. 
The appearance of a green variety of Cypripedium x Harrisianum can 
now be recorded, as it flowered a short time ago in the collection of H.
