We are but imperfectly acquainted with the Carices of the 
Andes of South America. This species may prove to be insepar¬ 
able from G. Pichinchensis. The principal distinction is the dis¬ 
tinctly subbifurcate orifice of the perigynium, the size of which, 
notwithstanding the more luxuriant growth, is more that of the 
var. /3 than the typical form; the rostrum too is shorter.

Since the description of O. Pichinchensis , in vol. xx. of the Lin- 
nean Transactions, from specimens gathered by Mr. Jameson on 
the mountains of Quito, I have obtained, through the kindness of 
Mr. Tuekerman, a figure of the original specimen in the Berlin 
Herbarium described by Kunth (which I have engraved in Tab. 
CXCIX.), and subsequently, through the kindness of M. Spach, 
have seen a specimen of Bonpland in the Herb. Mus. Paris, and 
also one from the Andes of Peru, gathered by M. Gay. The 
result from an examination of these specimens, has been to induce 
me to refer O. dura to a var. of G. Pichinchensis, and to doubt the 
specific difference of C. Lemanniana. 
Future observation must determine the character of G. Pichin¬ 
chensis, and the variations to which it is liable. Like many other 
species it was unfortunately described (to use Kuntli’s words) 
from a “specimen valde juvenile.” Any one familiar with the 
variable forms of Garex from youth to age, and from differences 
of soil or elevation, will understand the difficulty of arriving at a 
positive opinion drawn from a few specimens. I have no doubt of 
the correctness of my referring Jameson’s plant to that of Kunth, 
and should have considered O. dura to be distinct, but for the spe¬ 
cimen of M. Gay, which in some respects unites the two. The 
perigynium in Gay’s plant is the same in size and form as in G. 
dura, but is entirely smooth, as in the typical C. Pichinchensis. 
The scales are lanceolate and acuminate, and smooth as in G. Pi¬ 
chinchensis, while in G. dura they are rather ovate, and without the 
acuminated apex, and the central nerve is scabrous. The ache¬ 
nium in Gay’s plant is indented at the central margins, an abnor¬ 
mal defect, not observable in any of the other specimens. 
Tab. CXCIX. is a figure of the original specimen in the Ber¬ 
lin Herbarium, described by Kunth, the lower details, taken from 
Bonpland’s specimen in Herb. Mus. Paris; and Tab. CC. fig. I. is 
Jameson’s specimen from Columbia, which I originally described 
as G. dura. The perigynium a! and achenium f! are from M. 
Gay’s specimen.
