C. B. Clarke was certainly correct in placing Burman’s species 
as a synonym of Commelina benghalensis Linn., a very common 
Plant in the Indo-Malayan region,

The figure and description clearly indicate that Burman’s 
species is identical with the very common Indo-Malayan form 
currently known as Aneilema nudiflorum R. Br.

Burman’s species was based. on pre-Linnean references to 
Rheede and to Plukenet. The same species was described un- 
der the same binomial three years later by Linnaeus Mant. 2 
(1771) 222. A common plant in the Indo-Malayan region.

Burman’s binomial typifies Alpinia malaccensis Rosc., a species 
that has apparently been misinterpreted by modern authors; 
see Valeton in Merr. Interpret. Herb. Amb. (1917) 155. The 
type of the genus Alpinia, as described by Linnaeus, is Alpinia 
racemosa, of tropical America, which currently appears in
