have established this species from the figure of Rumphius. 
The O. sarcophyllum of Desvaux, (Prod, p. 193.) may be- 
long either to this species or the following, for he quotes 
both plants with a mark of doubt, and does not seem to have 
any other authority. ia

— We believe this plant will prove to be a mere variety, Or, 
perhaps, accidental state of O. reticulatum, from which it differs 
in no material points, The venation is said by Bory de St. Vin- 
cent to be the same; and in comparing it, which he does, with 
O. vulgatum, he remarks that the frond is more heart-shaped, 
and the scape shorter. Specimens of O. reticulatum answer- 
-ing to this description, and gathered by Sieber in the Mauri- 
tius, are now before us. Blume observes that the frond is 
sometimes oval, rounded and obtuse. x dtl
