valvis, perigonium nullum l|. in setis partitum aut lagenzforme, stamina 
antheris erectis apice integris, ovarium simplex uni-ovulatum, síylus 
in stigmata duo v. tria flssus. Fructus nucula v. caryopsis, triangula- 
ris v. compressus, monospermus, indehiscens; embryo ad basin albumi- 
nis farinosi. 
Cyperoide:z Juss. gen. 26. Cyperacez DC. fl. fr. IIl. 99. EndZicher 
gen. p. 109. Kunth. Bartl. Lindley. Nees ab Esenbeck. 
Radix fibrosa (rhizoma abbreviatum in fibras solutum), autrepens (rhizoma, 
verum), plus minus stolonifera. 
Culmi cylindrici, sepius angulati, simplices, nodis ad infimam partem hy- 
pogeam restrictis contigui, intus farcti. 
Folia e nodis oriunda, graminea; vagina, v. petiolus in vaginam connatis, 
integra; Zamina interdum nulla v. ad mucronem reducta, linearis, plana canali- 
culata carinata v. convoluta, margine integra v. serrulata; Zigua stipularis nulla, 
sed vaginz margine, lamine opposito, nonnumquam incrassaío. 
Inflorescentia: spica solitaria simplex vel spiculis fasciculatis, racemosis, 
paniculatis aut cymosis anthela. 
Spiculze hermaphroditze, diclines v. polygame, involucris bracteisque vario 
modo stipata, solitariae v. confer(z. 
Flores singuli: sguama (gluma, bractea exterior) univalvis, rarius bivalvis; 
perigonium nullum vel setiforme, e setis 3—6—00 squamaceis asperis v. 
mollibus, aut lagenceforme (utriculus: Caricinec&) e squamis 3, tertia scpis- 
sime obliterata, concretis formatum; stamina hypogyna 3 rarius 2, setis opposi- 
ta, filamentis filiformibus, antheris basifixis erectis linearibus acutis; ovarzum 
unicum liberum vel utriculo inclusum, ovulum basi affixum fovens; szyZus siu- 
plex, cum ovario sepius ariiculatus: stigmata 2—9, pilosa. 
Fructus (caryopsis, nucula) liber, pericarpium crustaceum, semzne erecto 
haud coalitum, embryo minimus, aZbumime farinaceo v. carnoso inclusus, cozy- 
ledone indiviso. 
Herba plerumque perennes, Gramineis maxime affines, sed culmo angulato, 
sub-enodi, farcto, vaginis foliorum integris, florum constructione et embryone 
intra albumen incluso optime diversae. — Ubique quidem vigent, loca tamen li- 
torum, riparum, paludum, pratorumque humida prz ceteris amantes. — "Vernali 
tempore virescentes, prima zstate florentes, ad foenisecium fructus maturos ple- 
rumque prabent. — Terrarum australiorum non aufugz, in regionibus septen- 
irionalibus pari fere cum Gramineis numero proveniunt.
