Culmus 3-I8-pollicaris, gracilis, triqueter, firmus, scaber, 
basi foliatus, rudimentis foliorum ferrugineis lucidis foliisque 
vaginantibus tectus; pars spicas gerens 16-28 lin. longa. 
Folia sub lineam lata, culmo longiora vei breviora, margi- 
nibus revolutis. Bractecs evaginatse; infima spicam mas- 
culam attingens, angusta; auriculse rotundatse, purpurese vel 
pallidse. Pedunculus infimus 4-10 lin. longus, scabriusculus. 
Squama; omnes purpurese, margine albo-hyalinse, nervo pal- 
lido. Spica mascula 5-7 lin. longa, feminea 2-7 lin. longa, 
2—2^ lin. lata; infima 7—13 lin. remota, tamen omnes con- 
tiguse. Perigynium (cum stipite 2 lin. longo) 1-1 lin. 
longum, -fV —to bn. latum, achenium laxe vestiens, nisi ner- 
vis 2 marginalibus enervium. Achenium p- t) - lin. longum, T ( y 
lin. latum, obovatum, triquetrum, angulus tertius posticus, 
castaneum, basi styli porrecta recta, vel depressa ; stigmatibus 
3, rarius 2. 
In aspect certainly like C. rigida {hyperborea), to which Tucker- 
man unites the Greenland plant; but the stigmas are, I think, 
normally 3, and the achenium always trigonous ; and the texture 
of the perigynium is, I think, firmer and granulate. I have not 
observed any plano-convex in form. 
The specimens figured are from Greenland, from Yahl, 44 C. ni- 
gritella, Drejerwith two perigynia from a specimen from 
“ Sitcha,” Herb. Fielding, “ O. stylosa,” Bongard,—the larger 
one rough at the margins.

We are indebted for this remarkable addition to the Phyllo- 
phorce to Mr. Brewer, who, in addition to his labours of the Sur¬ 
veying Commission, has admirably illustrated the flora of Califor¬ 
nia. The delicate texture of the large inflated perigynium allies 
it, in that respect, to C. Banksii and C. Mertensii. 
324. C. leiocarpa (Meyer); spica simplici dioica ferru- 
ginea, mascula oblonga, feminea cvlindrica teneri laxiflora 
nuda vel bracteata ; stigmatibus 2-3 ; perigyniis lanceo- 
latis sensim attenuatis stipitatis erectis, nervatis flavidis 
glabris, ore integro concolori, squama ovata acuta mucro- 
nata ferruginea, infima nunc cuspidata longioribus an- 
gustioribus.—C. leiocarpa, Meyer, Cyp. Nov. t. 5;

Hab. In Amer. septentrionali e.t Asia.—Unalaschka, 
Meyer. Sitka, Bongard. 
Radix repens. Culmus subpedalis, triqueter, scaber. Folia 
f- lin. lata, plana, culmum subsequantia. Spica mascula semi- 
pollicaris, 8-10-flora ; feminea subpollicaris, 1-11 lin. lata, 
laxiflora, basi interrupta. Squamae masculse obtusse, muticse 
vel mucronatse; feminese plerumque acute, infima subinde 
plus minus cuspidata. Perigynium l^o lin. longum, T % lin. 
latum, flavidum, concolor, inferne nervatum, nervis superne 
evanidis. Achenium (juvenile ) compressum. 
Torrey, in his N. Amer. Cyp., describes the stigmas occasionally 
to be 3, and the same is remarked in the FI. Rossica, though 
Meyer mentions only 2. I have figured the only specimens I 
have seen, which were sent to me by M. Fischer, from which the 
stigmas had fallen; and in the perigynium examined the achenium 
was compressed, implying the stigmas w r ere 2. In the 4 Flora 
Rossica ’ it is asserted, that 44 in basi spicse masculse subinde ad- 
sunt (flores) feminei aliquot, hinc species proxime accedit ad C. 
polytrichoidem, Muhl.” Meyer unaccountably thought it “affinis 
C. scirpoidece , Mich.” A reference to the perigynia of either will 
at once show that it cannot be allied to them. If it be dioicous, 
as Meyer and Torrey consider it, it has no affinity with any species 
of that group, unless with C. Davalliana, from which it differs in 
its creeping root, plane leaves, and erect perigynium. But if the 
spike be occasionally androgynous, apice mascula, as is asserted 
in the 4 Flora Rossica,’ it may prove to be inseparable from the 
C. anthoxanthea, Presl, a plant I have never seen, but of which I 
give a figure from the specimen described by Kunth, for which I 
am indebted to Mr. Tuckerman, who had it taken for me some 
years ago when he was in Berlin.

nodosa. Bracteae foliacese, culmo longiores, infima extra pe- 
dalis, plus minus vaginata. Spiculae mascuhe 2 poll, longse,

culus infimus pollicaris. Squamae conformes, masculse lineares

mam unam vel duas oppositas aristatas exsertas staminibus 
instructas, gerente, suppeditatum. {Vide t. 457c.) 
It is remarkable that this noble species, discovered by Dr. 
Bradley in 1829, has since escaped the observation of others. I 
have had the opportunity of examining the specimen in Herb. 
Torrey, which has 2 male and 1 female spike, with a sterile bract 
9 inches remote, furnished with a vagina 2\ inches in length. 
That figured is from Serb. Dewey, kindly sent to me for examina-
