cultivation is the orange-scarlet-flowercd 0. So/'/iro)iitis

ORNITHOCEPHALUS. 



Sir Joseph Hooker founded this genus of warm, 

 intermediate-house, epiph\-tal Orchids, belonging to the 

 tribe Vaiidcte. The name is deri\-ed from oniis, ornitlios, 

 a bird, and kepltalc, a head, and is in reference to the form 

 of the column and anther. The species are nati\-es of 

 tropical America, the onh" one probably in cultivation 

 being 0. grandiflorns [Liiidl.). Flowers yellow ; inflores- 

 cence manj'-flowered. Leaves large, oblong, blunt, acute or 

 obtuse. It is best suited b\- being grown in a basket, where 

 it can be suspended in a moist position. The compost 

 consists of two parts chopped sphagnum to one of peat- 

 fibre. Free drainage must also be afforded. It requires 

 a liberal amount cjf water during the acti\'e season of 

 growth, while in a dormant state only sufficient to keep 

 the foliage in a plump condition is necessar\-. 



0RN1TH0CHILU5. 



This small genus of stove or East Indian-house epi- 

 phytal Orchids belongs to the tribe J^amhw. The species 

 are natives of Burma and the Himala\-as. The name gi\en 

 by \\'allich is from ornis, oniithos, a bird, and cheilos, a lip ; 

 and is in allusion to the shape of the labellum. Flowers 

 small, pedicellate, disposed in lateral racemes ; sepals 

 spreading, the lateral ones rather broader ; petals rather 

 narrower than the dorsal sepal ; lip spreading at the base 

 of the column ; lamina two- or three-lobed. The species 

 are rarely found in cultivation outside botanic collections. 

 They require the same cultural conditions as Acridcs. 



OTOCHILUS. 



Three or four species of stove or East Indian-house 

 Orchids of the tribe Epidendrcce, natives of the Himalayas 

 and Burma, are found under the above-named genus. 

 Lindley's name is from cms, otos, an ear, and clictlos, a lip,
