1. U. Sinclairii, Boott ex Hook. f. Handb. N.Z. Fl. 309.— 
Rhizome stoloniferous. Culms 2—9in. high, rather stout, smooth, 
subrigid, erect or curved, obtusely trigonous, leafy towards the base. 
Leaves shorter than the culms or equalling them, flat, grassy,

A distinct plant, easily recognised by the small size, broad flat leaves, stout 
and pale spike, and scabrid utricles. It has recently been found in Fuegia.

I have followed Kukenthal in referring this to the Australian U. tenella, of 
which it has the slender flaccid habit. But it differs in the larger utricles, which
