This species varies in the form, degree of nervation, and smooth¬ 
ness of the perigynium, and in the form of the squamae. I am in¬ 
debted to M. Spach for a specimen of the C. inconspicua, Steudel, 
which in no respect differs from those of Cuming, Gay, and Dr. 
Hooker.

I described this species in the Lin. Trans, under the name of C. 
thecata from immature specimens from Herb. Preiss, sent to me by 
Mr. Ward. Nees had previously named it after its discoverer, and 
it was published by Lehmann in his ‘ Plant* Preissian* ’ in 1846, 
the year in which my paper was read. Drummond’s later speci¬ 
mens are more mature, and exhibit the purple spots on the 
squamae and perigynia, as shown in Tab. CLXXXYI. They are 
more conspicuous at the base of the perigynia. The aspect and 
habit are those of C. alveata, B., but the affinity is rather with C. 
extensa and its allies. 
174. C. barbata (Boott); spicis 4-5 ovalibus vel ob¬ 
longis gracilibus fusco-purpureis erectis contiguis, termi¬ 
nali mascula sessili, reliquis foemineis, superioribus sessi¬ 
libus evaginatis, infima subremota inserte vel paulo ex¬ 
serte pedunculata; bractea infima culmum longe supe- 
rante; stigmatibus 3; perigyniis ellipticis acute trique- 
tris emarginato-bidentatis superne vel ore marginibusque 
scabris punctis resinosis ferrugineis notatis pallide casta- 
neis leviter nervatis, squama ovata acuta mucronata vel 
obtusa mutica apice ciliata purpurea medio pallida carina 
scabra duplo longioribus. (Tab. CLXXXYII.)

rudimentis foliorum vaginisque rnaculatis tectus; pars spicas 
gerens If—2| poll, longa. Folia 1-11 lin. lata, culmo breviora, 
plana, rigida. Bractea culmo longiores: infima vaginata, 
elongata, s*pe altera sterilis longius vaginata, 21-5 poll, re¬ 
mota. Vagina 3-6 lin. longa, maculata. Spica mascula 5-9 
lin. longa, 1-11 lim lata. Spica foeminea 4-8 lin. long*, 
1^-2 lin. late. Squama omnes conformes: mascul* s*pe 
mutic*. Perigynium l T q lin. longum, 1 lin. latum. Ache¬ 
nium -j% lin. longum, 1 lin. latum, triquetro-ovale, pallidum. 
A C. Preissii abunde differt, spicis minoribus, approximatis, 
inferioribus foemineis, purpureis; perigyniis minoribus; squa¬ 
mis s*pe muticis; bracteis culmo longioribus ; culmo gracili. 
A C. lacistoma, Br., spicis majoribus evaginatis; perigyniis 
crebre costato-nervosis, ore insigniter albo-hyalino, integro, 
aperto, s*pe lacerato, gaudet. 
The only specimens I have seen of this species are those in the 
herbarium of Sir W. J. Hooker. They are not fully mature. 
From the presence of the sterile bract below the spikes it is pro¬ 
bable that the infloreseence may be found to extend to it. The 
nerves are generally less distinct than the figure exhibits them.
