Although the rather poor drawing does not show the charac- 
teristic mucronate tip of the rachis, and further presents but 
three spikes, this is clearly referable to the very common species 
currently known as Dactyloctenium aegyptiacum Willd. The 
only other possibility is Eleusine corocana (Linn.) Gaertn., 
which Burman otherwise described in the same work as Cyno- 
surus corocanus Linn.

No locality is cited, but three references are given to pre- 
Linnean literature. The species was described by Linnaeus one 
year earlier as Dactylis lagopoides Linn. Burman’s species may 
have included two distinct forms, but his figure is clearly the 
species currently known as Aeluropus villosus Trin.; he gives a 
reference to Gramen dactyloides javanicum Garzin herb., but no 
representative of the genus Aeluropus is known from Java.

Schoenus tuberosus Burm. f. FI. Ind. (1768) 19. “Habitat in Java &

This reduction has been made from Burman’s description; 
I have not seen the illustrations in Rheede and in Sloane which 
Burman cites as illustrating his species. 
* CYPERUS UMBELLATUS Burm. f. FI. Ind. (1768) 21. t. 9, f. 1. 
No locality is given by Burman. Regarding this species C. 
B. Clarke in Hook. f. FI. Brit. Ind. 6 (1893) 619 states “perhaps 
grass.” The description and figure appear to be based on a 
mixture of two entirely distinct forms. The stem and leaves
