Kunze’s figure of the perigynium does not accurately represent 
the turgid spongy base in a mature state. It is not a ring, but 
two lateral protuberances with a centi’al line between them. In 
the young state they are not apparent, though there is a disco¬ 
loration marking the site of the eventual deposition of spongy 
matter. I am indebted to M. Sonder for the specimens of Lech¬ 
ler ; n. 679, Arrique, was marked “ O. illustranda,” St. In 
Steudel’s Syn. Car., this species is “ Herb. Philippii, n. 194,” a 
specimen of which I have seen in Herb. Hooker and in that of 
Paris, both identical with those of Lechler. Steudel describes the 
perigynia of n. 194 as sterile, but in one I found a normal peri¬ 
gynium. 
The affinity of the species is with O. Bonariensis , Desf.

Culmus 9-18-pollicaris, obtusangulus, debilis, scabriusculus. 
basi foliis brevibus tectus; pars spicigera 1^-4 poll, longa. 
Folia radicalia culmo longiora, 2 lin. lata, firma, marginibus 
revolutis. Bractece vaginatse, cuspidatse, spiculis breviores. 
Vaginae 6-10 lin. longse, apice laxse, turgidse. Pedunculus 
informs 1—14 poll, longus, scaber. Squamae conformes, femi- 
nese inferiores subinde acutse. Spicula mascula 8-12 lin. 
longa, 1^-3 lin. lata, late ovalis vel elliptica vel clavata; 
femineae 6-12 lin. longse, 4 lin. latse. In uno specimine 
summa quasi geminata, infima spicula altera brevi composita. 
Perigynium (non maturum ) ellipticum, rostello longiore, de¬ 
mum globosum, 2h lin. longum, 1 T % lin. latum, rostello bre- 
viore lato, puberulum, demum glabrum. Achenium 14 lin. 
longum, 1~ lin. latum, orbiculatum, angulis 3 prominentibus, 
obtusum, basi productum, basi styli incrassata abrupte apicu- 
latum, fusco purpureum. 
A C. Michelii, Host., differt spicis densifloris ; perigyniis 
globosis, brevi lateque rostellatis, ore emarginato bilobato, 
lobulis latis brevibus, squamis ssepe emarginatis ; bracteis 
spicula brevioribus; vaginis magis turgidis. 
Hoppe’s figure exhibits the perigynium as it occasionally is 
seen before the maturity of the achenium, with a larger rostellum 
than in the mature state. Kunth figures the squama as acute, 
which is rather an exceptional form. The pubescence on the 
perigynium more or less disappears as it ripens. De Candolle 
describes it as smooth. 
The specimens figured are,— 
n. I. From Hoppe, sent to me by him as the “ O. rhynco¬ 
carpa, montosis Bannatis.” The separate spike from 
Kunze.
