SIR JOSEPH HOOKER’S COELOGYNE. 
COELOGYNE. Sepala subaequalia, erecta v. patentia, libera v. leviter cohaerentia. Petala sepalis conformia 
v. saepe angustiora nunc angustissima. Labellum ad basin columnae sessile, erectum, basi concavum et interdum 
breviter saccatum, lobis lateralibus nunc amplis erectis columnam amplectentibus v. involventibus, nunc brevibus v. 
fere obsoletis, lobo medio saepe expanso patenteque indiviso. Columna erecta, longiuscula, superne v. apice saepe 
bialata, apoda; clinandrium obliquum, saepe membranaceo-dilatatum, integrum dentatum v. antice biangulatum. 
Anthera intra marginem clinandrii affixa, subopercularis, incumbens, bilocularis, loculis basi v. fere undique confluen- 
tibus ; pollinia 4, cerea, obovata v. oblonga, compressa, per paria in loculis segregata, apice appendice granulosa 
polymorpha connexa. Capsula saepius oblonga, costis acutissimis et plus minus in alas expansis. 
Herbae epiphyticae, caespitosae v. longe repentes, Pseudobulbi secus rhizoma saepius crassi insigniter angulato- 
costati v. subteretes, apice saepissime diphylli. Scapi v. pedunculi alii inter folia terminales basi paucivaginati, alii 
sub anthesi ad basin pseudobulbi longius imbricato-vaginati, foliis sub pedunculo tardius evolutis, rarius ad apicem 
rhizomatis in caulem paucifoliatum abeuntes. Flores majusculi v. speciosi in pedunculo v. scapi solitarii, v. plures 
laxe racemosi. Bracteae saepe coriaceae v. subpetaloideae, deciduae v. persistentes. Labelli superficies saepe laminis 
v. lineis prominentibus dentatis ciliatisve cristata. 
Species ad 50, per Indiam orientalem et Archipelagum Malayanum late dispersae, una usque ad Chinam 
australem extensa.

his handsome species was discovered about the year 1849 or 1850 
| by Dr (now Sir JoszepH) Hooxer in the Sikkim Himalayas, between 
| 7,000 to 10,000 feet elevation. It was originally described as a pretty 
little plant, about four inches high, with almost the habit of Cypripedium guttatum. 
It is said to be common on mossy banks, and flowers in spring. Its discoverer 
states that there are certainly two forms in the Sikkim Mountains, or the lip 
is very variable. The typical form grows at the lower elevations. The other, 
afterwards called variety brachyglossa, by Reicuensacn, has the lip shorter and 
more open from the base, and more rhomboid when spread open. It grows 
at the higher elevations, from 9,000 to 10,000 feet above sea-level. The typical 
form is figured at t. 6388 of the Botanical Magazine, and was introduced to 
cultivation many years ago. The variety is said to have been introduced by 
2053
