sula to Silhet, where Zripleura and Cnemidia are found, and Georchis and Herpysma 
in Nepal. Anectochilus (Chrysobaphus, Wall. Tent. Fl. Nep.) is a genus found in 
Java; but A. Rorburghii, a species which exists in Silhet, Nepal, and as far north 
as the valleys near Choor and Kedarkanta. Zeuxina, Lindl. (Pterygodium, Roxb.) 
contains only one species. Z. sulcata, which is very generally diffused over the plains 
of India, and the only Orchideous plant I ever found in them, that is, in the Doab, 
and have specimens from as far north as the banks of the Sutlej, where it flowers 
in the month of January. 
The Neottiee of the more northern parts of the Himalayas, are better known in 
northern and temperate regions, as species of Spiranthes, Neottia, and Goodyera. 
S.amena, a species found in Eastern Siberia and the North of China, extends in the 
Himalayas from Silhet to Nepal ; and thence, with Goodyera procera, to Kemaon and 
Gurhwal. Neottia having only a single European species, has another, N. disteroides, 
in these mountains, near Mussooree, which Dr. Lindley considers as most remarkable, 
in having the brown habit, bird’s nest roots, and short round stigma of N. Nidus avis, 
but with the spreading perianth of Listera; and as thus confirming the propriety of 
keeping this genus distinct from Neottia. 
Epipactis is placed by Endlicher among Neottiee, but by Dr. Lindley among Arethusee. 
The genus is common, as well as Cephalanthera, in Southern and Central Europe ; ; 
the former is found in these mountains from the Sutlej to Silhet, and the latter to 
Nepal. The species are four in number, E. consimilis, Don, and E. macrostach ya ; 
whether or not these be distinct species, they are both very closely allied to the European 
E. latifolia. E.herbacea is a new species from Mussooree, and E. Royleana, another 
from Lippa, in Kunawur. Cephalanthera acuminata is common in Nepal and Mhassoo 
near Simla, as well as in the oak forests of Lundour, flowering in spring. Other 
Arethusee occur in Nepal, as the new genus Anthogonium, with two species of Pogonia, 
of which the others are found in North America. 
Vanilla, which is included in Arethuse@ by Endlicher, but separated into a distinct 
order, Vanillacee, by Dr. Lindley, is best known for its aromatic fruit, and as a 
produce of the hottest parts of Equinoctial America. The genus is also found in 
Tropical Asia, one species being indigenous in Penang and another at Singapore. Dr. 
Lindley informs me that Dr.Wight has a third, Vanilla pterosperma, 
Cypripedium, which alone forms the tribe of Cypripediea, is found in the temperate and 
cold parts of the northern hemisphere. It extends all along the Himalayas, at consi- 
derable elevations from Simla to Silhet. The species are highly ornamental. A. cordi- 
gerum, discovered in Nepal, is also found on Manma and Mhassoo. There is a new 
species in Lady Dalhousie’s collection from Simla. 
The Orchidee, remarkable for their extreme variety in form and appearance, as 
well as for the curious structure of their flowers, are much prized as objects 
of conics ture, Since modern science has shewn the causes of former failure, as well 
suring the present success by attention to principles which are of the
