G. fusiformis, Chapman, in my own and Mr. Carey’s herbarium, 
is in a younger state than the specimens of Buckley and Hale, 
and has the perigynium less excurved, and the female spikes 
longer, showing a transition from the abbreviate to the cylindric 
form of the spikes of the typical form, though they are all, except 
the lowest one at base, more densely flowered. They show also a 
transition into what Dewey has described as 0. ignota. The spe¬ 
cimens of it are more mature, and more or less lax-flowered, and 
the perigynium more or less excurved, its orifice oblique, entire 
or emarginate, and the lower peduncle often setaceous and pendu¬ 
lous. I can see no fixed characters that may serve to distinguish 
these varieties, and Mr. Curtis (Sill. Journ. vii. 410.1849) observes 
that C. styloflexa, which he says is common in the lower and middle 
region of North Carolina, and which he has received from Loui¬ 
siana and Florida, “ is a doubtful species.” Dewey describes the 
orifice of the perigynium as bidentate, though Buckley omits all 
allusion to such a character. I believe the normal state of it is 
entire or oblique, but from its delicate membranous texture it is 
easily ruptured. 
Of 36 specimens I find— 
13 with 3 spikes. In 1 the terminal spike is male at base, 
20 „ 4 and in 4 the lower females compound 
3 „ 5 at base. 
In one floret I observed a filiform racheola, shorter than the 
achenium; and in the specimens from Florida there is occasionally 
a slight tendency to roughness at the upper margins of the peri¬ 
gynium. 
87. Var. y. plantaginea; foliis culmeis bracteisque in¬ 
ferioribus 3-4 lin. latis, radicalibus 5-7 lin. latis 6-15 
poll, longis, spicis cylindricis laxifloris, mascula rarius 
abbreviata (Schk. f. 195).—C. plantaginea, Schk.f. 195.

patulifolia, Carey, Gray s Dot. 1. c. ed. 1. 
This differs from the typical form only in the breadth of the 
radical leaves. It is distinguished from the true C. plantaginea, 
Lam., by its foliaceous bracts.

yq-1 lin. longum, H lin. latum, basi styli obliqua abrupte

The narrow lax spikes, and the subabbreviate, slightly-curved or 
straight apex of the perigynium connect the var. a with the typical 
form; while the more abbreviated and abruptly curved apex of b 
connect it with the following var. e. I have received them both 
at different times under the names of both G. anceps and G. blanda. 
87. Var. e. blanda. — a. major; spicis 4-5 rarius 6 ob¬

evaginatis, inferioribus remotis longe exserte peduncula-
