specimens from Mr. Skinner. The flowers are very pale 

 green, almost white, with no spots or stains upon them. It 

 has not much beauty. It is near E. tripunctatum. A very 

 singular feature in it is the presence of one or two fine pointed 

 horns on the anther on each side, which give it, when seen 

 in front, the appearance of some insect's head. 



5. CLEISO STOMA dealbatum. 



C. dealbatum; foliis linearibus canaliculars carnosis dealbatis, spicis sim- 



plicibus glaucis, sepalis petalisque rotundatis, labelli calcare ovato emar- 

 ginato lobis lateralibus acutis intermedio ovato carnoso multo raajore 

 incurvo, columnae dente bilobo. 



An Orchidaceous plant of little beauty, obtained from 

 Manilla by Messrs. Loddiges, through Mr. Cuming. The 

 flowers before they expand are almost white, when open they 

 are bright yellow, with a white lip ; but they are too small 

 to produce much appearance. 



6. DENDROBIUM aqueum. 



D. aqueum, (§ foliis planis, floribus gemellis, labello trilobo) foliis ovato- 



oblongis undulatis acuminatis, floribus patulis cornu brevi obtuso, sepalis 

 petalisque ovatis, labelli trilobi pubescentis lacinia media ovata denticu- 

 lata basi alte excavata lateralibus latioribus rotundatis margine antenore 

 serrulato. 



A native of Bombay, whence it was imported by Messrs. 

 Loddiges, with whom it flowered in November, 1842. The 

 habit is that of D. Pierardi : the flowers are rather larger, 

 and of a pale watery green colour. 



7. PLEUROTHALLIS fcetens. 



P. /ceteris; folio ovali coriaceo subtus concolori cauli carinato triquetro 



sequali, spatba univalvi acuta coriacea striata pauciflora, floribus sub- 



sessilibus tomentosis coriaceis, sepalis oblongis convex* subsequabbus 



intus papillosis lateralibus connatis, petalis oblongis ac utis ?»«bnB denU- 



culatis subdiaphanis, labello lineari-oblongo obtuso l«vi hneis duabus 



elevatis carnosis basi excavato. 



A species very near the Mexican P. aphtkosa, with an 



unpleasant odour. It has no beauty, and is a native of 



Brazil, whence it was obtained by Messrs. Loddiges. Ine 



leaves are rather narrower than in P. aphthosa, and green 



not purple underneath.
