Descriptive Notes on Papuan Plants. 
The Javanic plant was cautiously disting'uished by Miquel (Plant. 
Junghuhn. i. 391) as var. Indica. The specific name, given by Bliime, 
would become ambiguous unless it coincides with the homonymous appel- 
lation, bestowed by Macfadyen on an Antillan plant, the Holosteum 
diandrum (Swartz Prodr, Deser. Yeget. Ind. Occid. 27), which however 
is reduced as a variety to D. cordata by Grisebach (FI. of the British 
West Indian Islands, 56). Should further researches prove Blume’s 
and Macfadyen’s plants distinct, then I would propose the species-name 
D. gerontogea for the former. Our species verges in structure of calyx 
somewhat to Polycarpon ; its wide dispersion through the tropic zone of 
the eastern half of the globe leads to anticipate, that this species will yet 
be found in North Queensland. A thorough systematic revision of all 
congeners is needed.
