I give the present and following species of this tribe as truly 
belonging to the genus Angrecum, upon the authority of Pro- 
fessor Lindley, who has done me the favour to examine and 
to name my entire collection of Orchidee, in all cases where 
the smallest doubt or difficulty occurred with respect to their 
determination. A. pectinatum is probably not uncommon on 
the forest-trees of the Mauritius, creeping on their trunks.
