bracts; and the perigynium larger, always smooth, often with 
more numerous nerves and ferruginous dots, and is within of a 
uniform violet colour. 
To show the resemblance in habit between the American and 
European plant, I find in 58 specimens of C. ancjustata ,— 
1 with 2 spikes. 24 with 1 male. 8 with 1 female.

In 16, the lowest 1 or 2, or all, were female. 
In 36, the upper 1 or 2, or all, were male at top. 
The var. /3 of the American plant is the form most nearly ap¬ 
proaching the usual appearance of the European one. Mr. 
Brewer has lately found in California specimens which, in habit, 
closely resemble the last, but differ in the perigynium being 
conspicuously toothed at the margin, and the vagina of the leaves 
externally scabrous. It differs from C. angustatci in these re¬ 
spects, and in the larger size of the perigynium. It is the C.

I have seen no other specimens than those found by Commodore 
"Wilkes, kindly communicated to me by Dr. Gray. The female 
squamae had all fallen. Whether it will prove distinct from C. 
microglochin must be left to future observation. The only known 
station for that smaller species in North America is Greenland.
