BaBMA; Prome, Wallich n. 3423; Karenia and Pegu, Kurz; Nummayan, E. 

 Scott. — Disteib. North Australia. 



Closely resembling R. Wightiana, but heads larger. Hypogynous Iristles 

 usually twice nut (exclusive of beak), in the upper half all are simply scabrous with 

 teeth pointing upwards, in the lower half the 3 inner (petals) are nearly glabrous, 

 the 3 outer (sepals) densely plumose. Nut nearly a in., often minutely bristly on 

 shoulders ; beak f nut, conic-oblong, not decurrent on nut. [There are several 

 closely allied Australian species included under B. longisetis both by Bentham and 

 Boeckeler.] 



Division II. Polycephal*. Spikelets in distant dense globose heads. 

 Stems with nodes and leaves far above base. — [The other species of this 

 division form the genus Gephalosohosnus proper of Nees, and have the nut 

 dorsally compressed; but the single Indian sp. has the nut laterally 

 compressed i.e. is closely allied to B. Wallichiana.']
