Thanks, Rohit ji,
These were blooming throughout the trails in Lava, Neora and Gorumara in
West Bengal.

Some extracts from Wikipedia link (for pictures & more details, click on the
link): http://en.wikipedia.org/wiki/Coelogyne (about Coelogyne genus)

*Coelogyne* Lindl. 1821, is a genus <http://en.wikipedia.org/wiki/Genus> of
over 200 sympodial <http://en.wikipedia.org/wiki/Sympodial>
epiphytes<http://en.wikipedia.org/wiki/Epiphyte>from the family
Orchidaceae <http://en.wikipedia.org/wiki/Orchidaceae>, distributed across
India <http://en.wikipedia.org/wiki/India>,
China<http://en.wikipedia.org/wiki/China>,
Indonesia <http://en.wikipedia.org/wiki/Indonesia> and the
Fiji<http://en.wikipedia.org/wiki/Fiji>islands, with the main centers
in Borneo, Sumatra and the Himalayas. They
can be found from tropical lowland forests to montane rainforests. A few
species grow as terrestrials or even as lithophytes in open, humid habitats.
The genera *Bolborchis* Lindl. <http://en.wikipedia.org/wiki/John_Lindley>,
*Hologyne* 
Pfitzer<http://en.wikipedia.org/w/index.php?title=Ernst_Hugo_Heinrich_Pfitzer&action=edit&redlink=1>and
*Ptychogyne* 
Pfitzer<http://en.wikipedia.org/w/index.php?title=Ernst_Hugo_Heinrich_Pfitzer&action=edit&redlink=1>are
generally included here. The genus is abbreviated
*Coel* in trade journals.

The wide distribution of this genus has resulted in a wide variety of
temperature variation from species <http://en.wikipedia.org/wiki/Species> to
species, some requiring cool to cold conditions to grow and bloom reliably,
while others need decidedly warmer temperatures to achieve the same.

The scientific name is derived from the Greek words *koilos* (hollow) and *
gyne* (woman), referring to the concave
stigma<http://en.wikipedia.org/wiki/Carpel>
.

This genus lacks the saccate base of the
labellum<http://en.wikipedia.org/wiki/Labellum>,
a typical characteristic which is present in the other genera in the
subtribe Coelogyninae. The free lip has high lateral lobes along the basal
part of the labellum (hypochile) and smooth, toothed or warty keels.

The pseudobulbs <http://en.wikipedia.org/wiki/Pseudobulb> of one internode
vary in size. They may be closely or widely spaced through
sympodial<http://en.wikipedia.org/wiki/Sympodial>growth along the
rhizome <http://en.wikipedia.org/wiki/Rhizome>.

Inflorescences <http://en.wikipedia.org/wiki/Inflorescence> often show a
small to very large number of showy, medium-sized to large
flowers<http://en.wikipedia.org/wiki/Flower>.
They may arise either from the apex of the newly completed pseudobulb at the
end of the growing season (as in *Coelogyne fimbriata*), or may precede the
new growth in early spring (as in *Coelogyne cristata*). The typical colour
range of this genus is white, through tawny brown to green, and occasionally
peachy tones. All species have four pollinia.

They have often a sweet scent, attracting different kinds of
pollinators<http://en.wikipedia.org/wiki/Pollinator>,
such as bees, wasps and beetles.

A few species are commonly known as 'necklace orchids', because of their
long, pendant, multi-flowered inflorescence.

The cooler growing species such as *Coelogyne fimbriata*, *Coelogyne ovalis*,
*Colegyne fuliginosa*, *Coelogyne cristata*, *Coelogyne flaccida*, *Coelogyne
nitida <http://en.wikipedia.org/wiki/Coelogyne_nitida>* originate in the
Himalayan region of India and southeast Asia. They require a decided rest
period during winter during which they receive no feed, very little water
(enough to prevent pseudobulbs shrivelling), cool to cold temperatures and
high light. These conditions seem to aid flowering in spring for some
growers, though others report that more constant conditions can also produce
regular flowering.
