rostellatis, ore integro ; foliis planis mollioribus. 
I have several specimens from the Altai of this species, sent to 
me by M. Fischer, but they are not all fully mature. The inflo¬ 
rescence is that of C. Moorcroftii, except that the terminal spite 
is male at base, sterile often at the summit. In one only is there 
apparently a terminal male spike, but this is unusually short, and 
the upper female portion may have been broken off, though I 
cannot detect any evidence of fracture. The perigynia on this 
specimen are elliptic and compressed, and have a ciliate mouth, 
contrasting with other specimens in this respect. Meyer de¬ 
scribes the perigynium “ subtrigonis elliptieis, ore kyalino integer- 
rimobut Kunth says, “ utriculi obovati, ore emarginato bi- 
denticulato.”

Radix fibris longis lanatis flavidis. Culmus 2-3^-pedalis,

5- 9 poll, longa. Folia 3-3 \ lin. lata, culmo breviora, glauco-

1-ro-ro h n - latum, hvalino-tenuissimum, nervis 2 marginalibus 
(intra margines sitis) percursum. Achenium longe stipitatum 
(stipite ttSiw lin. longo), te-1 lin. longum, lin. latum, 
triquetrum, ellipticum, pallidum, basi styli apiculatum. Stig¬ 
mata 3. 
Prescott describes this species as having two stigmas, but in 
specimens from Sitcha and other localities I find always three. 
Lyall’s specimens from “ the stream flowing into Chilukweyuk 
Lalee ” have broader spiculse and larger perigynia than those from 
Sitcha and the coast ; but there is an insensible gradation as to 
size in the specimens I have seen, several of Lyall’s in no re¬ 
spect differing from the typical form. In some of bis speci¬ 
mens the perigynia were morbidly elongated (4-5 lin. longa, 
fg lin. lata), with abortive achenia. The specimen figured is 
one of Lyall’s from the stream alluded to, and may be contrasted 
with the figure in FI. Bor. Amer., which represents the coast 
form. The affinity is with C. Bcmksii, B.

Spica 10-12 lin. longa. Spicula mascula 7 lin. longa, sub 
lineam lata, sessilis vel breve pedunculata; fendnece 3-5 lin.

culee. Squamce conformes; masculse obtusse. Perigynium 
LroteV h n - longum, -rg—l-ro hn. latum, glaucum, plus minus 
nervatura, nervis concoloribus (sub lente) ferrugineo-puncta- 
tum. Achenium f {) lin. longum, Zf lin. latum, insequaliter 
triquetrum, obtusum, basi productum, basi styli sequali apicu¬ 
latum, fulvum. Stigmata 3 vel 2. Stylus exsertus. 
The affinity is, I think, with the Limosce. In the FI. Rossica 
the stigmas are said to be rarely 2, generally 3. I observe both 
numbers, but the only mature achenium I have found is trique¬ 
trous.
