upper side. Spikes solitary, 4 to 5 lines long ; the scales somewhat

Hab. Tn the vicinity of Pago-pago Bay, Tutuila, one of the Samoan

Plant small and creeping. Stems rigid, nearly round, prostrate, 2 

 or 2£ inches long, of a pale straw colour, interruptedly bisulcate on 

 the upper side, and slightly corrugated on the under side, emitting 

 roots from the axils of the somewhat erect and twice or thrice 

 divided branches. Leaves of a dark green colour on the upper, and 

 of a paler green on the under side, about a line long, and half a line 

 broad, a little distant on the main stem, spreading, ovate-oblong, 

 somewhat acute, with the point turned upwards, keeled on the upper 

 side, ciliate-serrate at the base, the inferior margin finely serrated or 

 sometimes entire, the superior half of the base oblique. Stipules 

 about half the size of the leaves, distant, oval, apiculate, serrate, the 

 point turned a little inwards, slightly keeled on the upper side. 

 Spikes 2 to 4 lines long, solitary, or sometimes in pairs. Scales 

 ovate-oblong, acute, spinulose-serrate. Antheridia globose ; the powder 

 amber-coloured. Oophoridia globose, enclosing 2 or 3 round and 

 slightly angular grains, of a whitish colour. 



Our plant differs a little from that described by Spring ; the spikes 

 being somewhat longer, and the margin of the scales not so decidedly 

 ciliate.
