Flores hermaphroditi, regulares. Perianthium inferum, duplici serie 3-merum, exterius 
calycinum, interius corolinum. Calycis tubus bxabnus interdum brevissimus v. vix 
ullus; lobi paleacei, rigiduli, l lati, acuti, sesti convoluto-imbricati. Corollce 
"n sepius hyalinus, cylindraceus ; lobi late ovati, patentes, petaloidei, sestivatione late 
convoluü. Stamina 6, fauci affixa, corolla breviora, erecta; filamenta brevia, ssepius 
brevissima. —Anfhere lineares, basifix:e, obtuse sub-4-gonsm, introrsum suleatz, basi 
saltem 4-locellatze, locellis superne confluentibus, apice poro unico introrsum obliquo v. 
rima brevi (rarissime poro duplici?) dehiscentibus. Ovariwm superum, sessile, corolle 
tubo inclusum, obtusum retusum v. 3-lobum, perfecte v. interdum imperfecte 3-loculare. 
Stylus terminalis v. inter lobos ovarii affixus, crassiuscule filiformis, indivisus, stigmate 
terminali parvo indiviso vix v. non incrassato. Ovula in quoque loculo solitaria v. pauca 
(interdum usque ad 8), a fundo erecta, v. axi lateraliter affixa, anatropa. Capsula sessilis, 
basi spe pericarpio membranaceo indivisa, superne spe latior v. interdum a basi lata, 
pericarpio (excepto Spathantho) rigidulo, in valvas 3 medio septiferas dehiscens. UM 
ubi nota ovoidea oblonga v. .bglot ; testa la levis v. minute reticulato-striata, 
apice interdum in áppendicem - DOE conicam v. mitrzformem albidam celluloso-sub- 
spongiosam producta. Albwmen copiosum, farinaceum. Embryo lentieularis, prope hilum 
albumini applicitum. 
Herb» perennes, Smpe paludosce seepiusque robuste, rhizomate crasso brevi. Folia 
radicalia, vaginis sepius distiche imbri longis angustisque v. latissimis 
crassisque, lamina late lineari lanceolata v. obla seepius longa, acuminata, basi petio- 
lata v. in vaginam sessili ; costa parum promi venis 1 libus tenuibus subparalleli: 
interdum venulis t is minimis feticulstó-cotinexis. Scapus inter folia 
erectus, simplex, nudus, v. basi vagina interdum laminam brevem ferente stipatus. Flores 
(excepto Spathantho) in CAPIO Serm globoso v.  Iatiusculo meus v. in una specie 
breviter pedicellati, singuli b ibus perianthii

usque ad fructus maturitatem persistunt. Bractem pitulum inyol stepi ime 9,

capitulum spiciforme, secundum, bractea unica spathacea erecta inclusum. 
Species ad 20 Brasilianze v, Guianenses, parum intra fines Venezuelze extensze. 
Ordo poris, olim sub nomine Rapatee inter genera Juncaceis affinia inclusus, insigniter tamen 
differt i inibus et seminibus. Ab ordinibus precedentibus albumine 
farinaceo donatis distinguitur i imprimis ovulis anatropis, embryone juxta hilum lenticulari. Semina 
iis Flagellariearum accedunt, sed habitus perianthium ete. longe distant.
