sicca, chartacea, 3-locularis, 3-valvis; valvulæ ab apice loculicide 
reflexæ, ssepe imprimis ad dimidiam partem serius usque ad basim 
dehiscentes, persistentes; placente cum valvis reflexæ, vel rarius ut 
columna eentralis triquetra relictæ. Semina in unoquoque loculo 2 
(aut casu 1-0) superposita, planum secus horizontale arete approxi- 
mata, eylindraceo-pyramidata. Hilum fere punetiforme ; prope basim 
seminis superioris apicem inferioris situm ; sin autem altero ovulo 
abortiente loculus 1-spermus evadit, dein hilum prope mediam par- 
tem seminis videtur. Embryostega circularis umbonata ; in apice 
seminis superioris, in basi seminis inferioris sita, utraque horizonta- 
lis (tab. 5, fig. 5, 6, 7). Embryo juxta embryostegam situs, ad axim 
capsulæ parallelus, verticalis, quoad hilum transversim remotus. 
Testa firma, crustacea, fusca vel nigra, interdum obscurius verticali- 
ter striata, in facie interiore vel undique foveolata rugosa aut im- 
presso-punctata, rarius levis. 
erbæ ramosæ. Folia angusta rarius oblonga, basi amplexicaulia 
sepius vaginata. Flores fere regulares, singulus bracteola (bractea 
propria) majuscula suffultus ; ssepius in cymas densas biseriatim aut 
irregulariter congesti, rarius pauci (vel 1) in apicibus ramulorum 
racemulosi. — Genus admodum naturale, ab omnibus aliis facillime 
recognoscendum, a Tradescantia remotum, et a R. Brown (Prodr. 
p. 269) optime stabilitum verbis paucis scilicet : « seminum collatera- 
* lium altero erecto altero pendulo, umbilico basilari, embryone in 
« extremitate opposita. » — Species plures inter se affines forsan ulte- 
rius conjungend:e. 
Species 35; in calidis Orbis Veteris, nempe in Africa, India, Malaya, 
China meridionali et Australia tropica vigentes.
