226 Dr. Hooker and Dr. Greville on the Genus Hookeria 



Hab. Nepaul, Dr. Wallich. 



Similar in size and habit to H. lucens, which it also resembles in the 

 horizontal dark-coloured capsule and pale entire and reticulated calyptra. 

 Its acute leaves, however, constitute a remarkable point of difference 

 between the two species.

Hab. Near Rio Janeiro. Mr. Jameson. 



The stems of this species are two or three inches in length, pinnated 

 with small ramuli three or four lines long ; the leaves of the ramuli are 

 ovato-lanceolate. Its fructification is unknown. 



4. H. Jlavescens, caule vage pinnatim ramoso, ramis bre- 

 vibus simpliciusculis subcompressis, foliis undique laxe im- 

 bricatis ovato-acuminatis integris enervibus perichaHialibus 

 lanceolato-acuminatis, capsula nutante, calyptra basi multifida. 



Hab. Demerara. C. S. Parker, Esq. 



Stems creeping, irregularly pinnated with short branches. Leaves 

 pale yellow green, the lower ones inclining to brown, shortly, but very 

 sharply acuminated, entire, nerveless, somewhat reticulated, and of a 

 thin and membranaceous texture. — Pl. V. fig. l.^Cauline leaf; 2. 

 perichaetial leaf.

 late obovatis obtusissimis integerrimis immarginatis succulentis 

 opacis medio diaphano laxe reticulato, nervo infra apicem 

 evanescente " capsula erecta urceolata exigua. 1 '

Hab. South Sea islands. 



We only possess specimens of this moss without fructification from 

 Mr. Dickson. The habit and structure of its leaves are quite peculiar, 

 though at first sight it bears some resemblance in the former particular 

 to H. cristata. 



6. H. Dicksoni, subcompressa, foliis late ovatis acuminu- 

 latis tenuissimis pellucidis marginatis subundulatis integerri- 

 mis pulcherrimo-reticulatis, nervo ultra medium evanescente, 

 capsula nutante, calyptra, basi (ut videtur) laciniata. Pl. V.
