C. — MABA- [J. R.' et G. Forster, Characteres Generum Plantarum, 
p. 121, t. 61 (1771).] 
O.) Notæ e morphologie. — Flores diœci, rarissime monœci v. 
polygami, plerumque trimeri, rarius 4-6 meri. Calyx campanulatus 
V. oblongus, non plicatus, lobatus v. truncatus ; corolla campanu- 
lata V. tubulosa, lobis in prefloratione sinistrorse contortis. 
Flos masculus ; stamina 3- co, plerumque glabra rarius pilosa v. 
pubescentia. Ovarium abortivum. 
Flos femineiis ; staminodia o-oo , plerumque pauca; ovarium 3-v. 
6-loculare, 6-ovulatum; fructus plerumque mediocris, baccatus. 
Arbores v. frutices, foliis alternis integerrimis, inflorescentia 
axillari v. rarius laterali. 
[Alph. DG. Prodr. VIII, p. 240, n. VU (1844)] — (Sec. Hiern), 
Folia. — Pili unicellulati simplices, sæpe materia rubra farcti. 
Stomata cellules epidermidis pluribus irregulariter dispositis cir- 
cumvallata. Crystalla simplicia, clinorhombica, sæpe faciebus 
concavis, v. diverse truncata, nunc glomerata v. echinata. 
Caiilis. — Vagina sclerenchymatosa e pericyclo ortum. 
b.) Epharmosis. — Epidermidis cellulæ recticurve delineatæ, 
V. undulatim. Stomata supra nulla, ad æ.quilibrium epidermidis, 
aperientia, v. exserta. Pili nulli, v. rari, v. numerosi, v. folia 
glabrata. Crystalla illuminatoria in parenchymate paliformi, v. 
nulla. Hypoderma nullum (extra M. humilis). Mesophyllum bifa- 
ciale. Nervorum lateralium fasciculus non immersus, sæpissime 
fibris mechanicis utrinque armatus. Nervi medii fasciculus non 
immersus, raro immersus, sæpissime vagina fibrosa subcontinua 
inclusus, sæpissime parenchymate sine colore cum epidermide 
supra conjunctus. Pelioli fasciculi (1-7). Spiculæ nullæ, v. intus 
nervorum petiolique parenchymate, et in phloemate caulis. 
Periderma caulis subepidermide. Yasa caulis cum punctatione 
areolata et cum diaphragmate foramine ovato perforato.
