1. Arctophila trichopoda Holm, nov. spec. 
Stoloniferous: culms weak, about twenty em in height, enclosed by 
the leaf-sheaths: leaf-blades broad, flat and glabrous, longer than the 
internodes: inflorescence a lax-flowered panicle with the glabrous, capillary 
branches in twos or threes: spikelet three-flowered, one or two on each 
branch: empty glumes unequal, quite broad. acuminate, membranaceous, 
three-nerved: flowering glume broad, pointed and often awned, at least 
in the basal flower, hairy at the base: palet bidentate, shorter than the 
flowering glume. 
A near ally of A. mucronata Hack. 
Mansfield Island and Nottingham Island, Hudson Bay: collected by 
Dr. R. Bell. 
2. Dupontia micrantha Holm, nov. spec. 
Stoloniferous: culm slender, glabrous, about twenty five em in height: 
leaves very narrow, glabrous with prominent ligule: inflorescence a con- 
tracted panicle with capillary branches: spikelets one or two on each 
branch, mostly one-flowered: empty glumes unequal, very narrow and 
sharply pointed, membranaceous: flowering glume acute, slightly hairy at 
the base, not exceeding the superior empty glume: palet bidentate, a little 
shorter than the flowering glume. 
Readily distinguished from JD. Fisheri and psilosantha by the small 
size of the spikelets and very narrow leaves, 
Halton, Labrador; collected by Waghorne. Cape Henrietta Maria, 
Hudson Bay: collected by Spreadborough. 
3. Glyceria paupercula Holm, nov. spec. 
Caespitose, perennial: culms low, curved or decumbent, mostly leafy 
to the panicle, the base of which is often enclosed in the leaf-sheath: 
leaves narrow, flat, glabrous, the blade about as long as the sheath: 
panicle pyramidal and open during anthesis, more or less contracted 
afterwards: spikelets three- to four-flowered, seldom five-flowered: empty 
glumes unequal, the lower the shorter, both much shorter than the 
Repertorium novarum specierum. 29
