Sepala 3-5, petala 3-0, et stamina 6-00, nune omnia libera et hypogyna, nune interiora 
v. omnia toro carpella includenti (ovario pluriloculari) basi adnata v. ad ejusdem apicem 
inserta (perigyna v. epigyna). 4nfAere erecte, connectivo cum filamento continuo loculis 
adnatis introrsum v. extrorsum rima longitudinali dehiscentibus. —GnecH carpella 3-90, 
libera v. toro plus minus immersa et annulatim v. inordinate cum eo concreta (in ovarium 
-o-locularem, superum, semisuperum, v. inferum coalita). — Stigmata distincta, v. disco 
epigyno (ovarii apice disciformi) adnata, radiantia v. annularia. Ovula v. solitaria ex apice 
pendula, v. oo parietibus nec angulo interno affixa, seepissime pendula, orthotropa.  Carpell 
matura indehiscentia, distineta v. in fruetum carnosum spongiosum v. pulposum coalita. 
Semina arillo carnoso v. pulposo immersa v. nuda, nunc albumirosa, embryone orthotropo 
intra albuminis farinacei cavitatem prope hilum semi-immerso et intra sacculum amnioticum 
incluso, nune exalbuminosa; cotyledonibus crassis plumulam sepe insigniter evolutam 
foventibus; radicula brevissima. 
Herb: aquaticce, rhizomate submerso, folia et scapos unifloros, rarius ramos foliatos na- 
tantes emittente, Folia petiolo longo super aquam natantia, rarius emersa, scepius peltata, 
vernatione involuta, submersa nonnunquam dissecta. Flores plerumque natantes, et spe- 
ciosi, nune emersi. Fructus nune emersi nunc sub aqua maturescentes. 
Species ad 35 in aquis puris quietis v. fluentibus orbis fere totius vegetantes. 
Affnitas ordinis omnino eum ZAalamifloris apocarpis intelligitur, etsi genera ineludit syncarpica, 
imo ovario omnino infero donata. His tamen carpella theoretice toro qui illa arcte circumdat et 
swpe in centro processum conieum v. subglobosum ultra carpella exserit, immersa dicuntur. A 
ceteris Ordinibus hujus Cohortis Nymplueaees differunt imprimis embryone, ovulis parietalibus 
(haec etiam in Zerberideis nonnullis observantur), et habitu.
