116 MONOCOTYLEDONEÆ. 
similia; libera aut (in Coleotrype, Zebrina, Weldenia) prope faucem 
corolla tubi inserta; in 2 verticillis, altero exteriore cum sepalis 
alternante, sita; stamen petalo exteriori antepositum (nisi in Coch- 
liostemate) fertile. Filamenta linearia raro oblonga ssepius filiformia 
(in Cochliostemate lata spathulata), haud raro pilis monileformibus 
ornata; staminum infertilium sæpe dissimilia; superne in speciebus 
paucis Cyanotidis et Tradescantiæ dilatata. Antheræ loculi 2 (iu 
Cochliostemate, specie saltem, 1), oblongi aut rotundati, introversi 
aut sublaterales, rimis plus minus elongatis (in Dichorisandra poris 
apicalibus) dehiscentes; connectivum angustum, aut dilatatum arcui- 
tumve loeulis in margine inferiore sitis; antheræ in staminibus minc- 
ribus dissimilibusve sspe dissimiles. Pollen parvum, ellipsoideum, 
ssepe longitudinaliter sub-3-striatum, luteum aut albidum. Ovarium 
liberum, sessile raro breviter substipitatum, ovoideum aut anguste 
oblongum, 3-2-loculare (dum novum est in Cochliostemate paucisque 
aliis sub-1-loculare, earpellis imperfecte coalitis) ; loeulus tertius doi- 
salis sepalo exteriori antepositus sepius minor haud raro deficiens. 
Stylus linearis aut filiformis (in paucis speciebus Tradescantiæ € 
Callisiæ curtatus), simplex, secundus, in novo flore sæpe curvatus, 
nisi in paucis speciebus Cyanotidis glaber, interdum infra apicem 
incrassatus fusiformis. Stigma terminale, simplex aut obscure 32 
lobum, punetiforme aut capitellatum, rarius breviter penicilliforme: 
Ovula anatropa aut sæpius semi-anatropa, in quoque loculo 2-ec aut 
1; sæpe in loculo dorsali quam in 2 loeulis ventralibus pauciora: 
angulo interno affixa, subglobosa, in 2 placentis subconfluentibus 
vertiealiter superposita; subhorizontalia, summum subadscenden* 
infimum subpendulum ; aut, in loeulis 1-ovulatis, ovulum ex angulo 
interiore fere basali subadscendens. Fructus capsularis ab apice locu- 
licide 3-2-valvis, aut erustaceus indehiscens, rarius (in paucis specie- 
bus Palisotæ) epicarpio succulento baccatus ; globosus aut lanceolatus, 
3-2-gonus ; 3-2-locularis, raro (in Commelina Sect. Heterocarpo, Y 
Aneilemate Sect. Rhopalephora) abortu fere 1-locularis. Semina 
ssepius totidem quot ovula ; in quoque loculo in unica serie columni- 
formi, rarius in 2 seriebus imbricatis (in Cochliostemate in 2 seriebus 
parallelis verticalibus) superposita; nonnunquam, in fructibus inde 
hiscentibus, rhomboidea, in sphæram fere conjuncta. Testa firmi. 
interdum fere ossea, sicca (in Dichorisandra pulpo immersa, in Coch- 
liostemate mucilaginosa) ; rugosa, foveolata, radiato-striata, reticu 
lata aut leevis. Hilum ventrale, in seminibus cylindricis lineare verti- 
cale, in seminibus rhomboideis fere punctiforme. Micropyla lateralis.
