404 MR. C. B. CLARKE ON CAREX TOLMIEI. 
Seemann no. 2207 was pasted down in herb. Boott on the 
type-sheet of C. Zolmiei (with Tolmie’s plant). It appears to 
me widely different ; the utricle is broad, flattened, and the nut 
is much narrower than the utricle. I call it simply C. ustulata, 
Wahlenb. ; if not that, I maintain it to be very close thereto. 
I give next a diagnosis of Boott’s adjacent species :— 
Carex nicEnLA (Hook. Fl. Bov.-Amer. ii. [1839] p. 225); 
spicis 4; utriculis 3 mm. longis (4. e. quam ii C. Tolmiei longiori- 
bus); glumis feemineis apice lanceolatis utriculos plane super- 
antibus; ceteroquin ut C. Tolmiei—Boott, Carew, p. 194 et Le. 
Ined. 654 in herb. Kew. 
C. Tolmiei, Boott, Carex, p. 100 partim (7. e. Fischeri exem- 
plum et C. Wright n. 22). 
C. melastoma, Fischer MS. 
Habitat. Columbia River ; Yolmie. Behring Straits: Arakam 
Ins., C. Wrighti n.22 ; St. Paul Ins., Langsdorff in herb. Fischer. 
It appears doubtful whether this species can be retained as 
other than a variety of C. Zolmiei. In the type of C. nigella of 
Tolmie the spikes are little less dense than in C. Tolmiei; but 
there is in herb. Kew another plant collected by C. Wright on 
the Ringold and Rodgers Expedition, called “ C. Zolmiei” in 
herb. Kew, in which the spikes are much more lax. As to 
Fischer’s plant and C. Wright n. 22, they agree with C. nigella 
much better than with C. Tolmiez. 
The remaining C. folmiei in Boott’s herb. I call new species 
as follows :— 
CAREX LEPTOSACCUS, sp. nova; spicis 4, terminali muscula ; 
spicis fomineis 3 mm. latis, vix densis; utriculis 2 mm. longis, 
ovoideis, compressis, suberostratis, papyraceis; stylo 3-fido ; 
nuce obovoidea, trigona, quam utriculus paullo angustiore. 
C. Tolmiei, Boott, Carex, p. 100 partim. 
Habitat. Behring’s Straits: Arakam Ins., CO. Wright ». 23. 
The young female spikes are deep brown ; but the fruiting 
spikes are variegated with white, the female glumes having 12 
them broad scarious margins towards their summits. This, a8 
well as the papyraceous utricles, might possibly be a consequence 
of imperfect ripening, 7. e. the glumes may here be withered. 
But, if that should be so (and in one of the utricles I have found 
a nearly ripe nut), the broad utricle will not do for C. Zolnier,
