A number of species which do not occur wild in the Malay Peninsula were 
recorded by mistake in Hook. fil. F.B.I., either mis-identifications or from 
garden plants. The fine A. nutans, Roscoe, with very long hanging panicle 
of large flowers, occurs in gardens only. A. malaccensis, Roscoe, apparently 
a native of India, is occasionally to be seen in gardens, but is not a native of 
the Malay Peninsula.
