SCIRPUS FLUITANS, L. Ankafana.— Deans Cowan. 
This eosmopolitan plant does not seem to have been previ- 
ously recorded from Madagascar. It is of the typical form. 
S. CORYMBOSUS, Heyne, var. MINOR, Bæckler. (S. brachyceras, 
Hochst.). lmarina (Hildebrandt, 3789). Andrangaloaka, East 
Imarina (Hildebrandt, 3733). 
FIMBRISTYLIS SCHŒNOIDES, var. CILIATA, N. var. 
This variety differs from the typical form in its shorter leaves, 
with the testaceous vaginæ ciliated at the mouth with white 
hairs. The glumes are brown and velvety with ciliate margins ; 
the tip also of the involucre is hispid. The stamens have long 
white flattened filaments, and oblong apiculate chocolate-brown 
anthers. In one flower the style was bifid, but usually, as in the 
type, they were trifid. The specimens were collected by Hilsen- 
berg and Bojer in Madagascar without specific locality. The 
typical form is African.

"Auf trocknen Hiigeln, Sirabé, N. Betsileo, Madagascar, Aug. 
1880."—J. M. Hildebrandt, 3597. 
This plant belongs to the Oncostylis section of Fimbristylis, 
and has some affinity with F. capillaris. It is remarkable for the 
dense ash-coloured wool covering the leaves and culms to near 
the top, giving the plant the appearance of being attacked by a 
mildew.
