5 



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. CLEISOSTOMA dealbatum. 



G.dealbatum; foliis linearibus caualiciilatis caruosis dealhatis, spicis sim- 

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

 giuato lobis lateralibus acutis intermedio ovato carnoso multo majore 

 incurve, 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 coniu brevi obtuse, sepalis 

 petalisque ovatis, labelli trilebi pubescentis lacinia media ovata denticu- 

 lata basi alte excavata lateralibus latioribus rotundatis margine anteriere 

 serrulate. 



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 fetens. 



p. fcetens ; folio evali ceriaceo subtus cencoleri cauli carinato triquetra 

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

 sessUibus teraentosis coriaceis, sepalis eblongis convexis subsequalibus 

 intus papillosis lateralibus cennatis, petalis oblougis acutis glabris dcuti- 

 culatis subdiaphanis, labello lineari-eblengo obtuse Isevi lineis duabus 

 elevatis carnosis basi excavate. 



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

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

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

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

 not purple underneath.
