The specimens in the Collection agree sufficiently with the above character. To us, this species seems 
closely allied to R, fusca. 
2. Rhynchospora paniculis densis erectis rigidis axillaribus, squamis ad- 
pressis, foliis rigidis margine dorsoque scabris culmum triquetrum aequantibus. 
Culmus erectus, foliosus, triqueter, glaber. Folia rigida, linearia, dorso margineque scabra, culmum 
aequantia. Spicas dense fasciculato-paniculatse : paniculm axiUares ; spiculm triflores. Squama adpressse, 
oblongo-lanceolatse, mucronato-aristatse, glabrae. Achenium rotundum, lenticulari-compressum, longitudin- 
aliter punctato-lineatum, glabrum ; rostellum ensiforme, achenii latitudinem aequans, longitudine duplo super- 
ans. Stylus elong-atus bifidus. Seta hypogynse 4-6 capiUares, retrorsum scabrae. 
1. Cyperus mucronatus. Valil. — Roem. et Schult Syst. Veget. v. 2. p. 167. Spreng. Syst. 
Veget. v. p. 217. 
Found in the Island of Oneeheow. 
2. Cyperus brunneus; spicis lanceolatis glomerato-corymbosis, squamis striatis, invoiucro 
3-phyUo elongate, foliis linearibus culmum triquetrum sequantibus. Spr. — Sw. — Roem. et 
Schult. Syst. Veget. v. 2. p, 176. Spreng. Syst. Veget. v. 1. p. 219. 
3. Cyperus ccespitosus; spicis lineari-oblongis compressis umbellato-glomeratis, umbellis 
umbellatis pedunculatis, squamis obtusis margine scariosis, invoiucro triphyllo elongate, 
culmo filiform! triquetro, foliis linearibus planis. Spr. — Roem. et. Schult. Syst. Veget. v. 2. 
p. 194. Spreng. Syst. Veget. v. p. 221. 
4. Cyperus paniculatus ; spiculis lanceolatis compressis horizontalibus remotiusculis, 
squamis duabus inferioribus subulatis vacuis ceeteris obtusis striatis, umbellse umbellulseque 
radiis alternis, invoiucro partial! nullo universal! poly-(8)-phyllo, foliolis tribus elongatis, 
culmo acute triquetro. — Rottb. in Gram. p. 40 ? Roem. et Schult. Syst. Veget. v. 2. p. 189 ? 
Spreng. Syst. Veget. v. \. p. 223? 
We feel extremely doubtful about any of the S 5 Tionyms. Our plant, judging by a solitary imperfect speci- 
men, is nearly allied to C. strigosus. 
5. Cyperus strigosus^ spicis lineari-subulatis confertis horizontalibus remotiusculis, um- 
bellulae radiis alternis, invoiucro pentaphyllo elongate foliis culmum sequantibus. Spr . — 
Linn. — Roem. et Schult. Syst. Veget. v. 2. p. 214. Spreng. Syst. Veget. v. 1. p. 226. 
6. Cyperus trachysanthos ; spiculis oblongis compressis plurimis glomerato-umbellatis, 
umbellulis ultimis confertim umbellatis subternis, squamis ovatis mucronatis apice recurvis 
dorso denticulis asperatis, invoiucro triphyllo elongate, culmo trigono. 
Sometimes the rays of the umbel are not again divided, but bear the ultimate sessile spikelets in a head 
at their extremity. There are two varieties in the Collection, one with spikelets, containing about thirty 
flowers, and the culm free from all asperities j the other with shorter, more ovate spikelets, of from eight to 
ten flowers, and the angles of the cuhn scabrous near the umbel. In this last, the ultimate umbels are not 
half the size of those in the first variety. 
7. Cyperus caricifolius ; spiculis patulis spicatis racemosis ovato-oblongis turgidis con- 
gestis, squamis subrotundis concavis obtusis nervosis albidis, invoiucro partial! nullo univer- 
sal! 5-6-phyllo elongato, culmo obtuse trigono, foliis carinatis margine carinaque scabris.
