Wightl, c. : Epiphyte on branches of irces. From ihe Pulneys. Flowers rose 

 coloured. The specimen from which ihe species was originally taken up werc far 

 from good, and the cbaracier is unavoidably impcrfect, but suflicicntly so LD lcave 

 little ground to doubt, ihat ihis is ilie plant. i have quoied Richard (Aerides 

 radicosum Ann. sc. nat. Vol. 15.) wilh a doubt , ihough I bclicvc unneccssarily, his 

 dcscription and figure agreeing so well witli niy planl. The eiect not recumbent co- 

 lumn and ercct, not 3-lobed lip of this plant show thai it is not referablc to Acrides, 

 at lcast as dcflncd by Lindley.
