concavo sacciformi, germen adnatum intus fovente; calyce 0. Corolla 
gamopetala regularis, rotata v. subcampanulata ; lobis 2, 3, v. sæ- 
pius 4 (Galium),v. 5 (Eurubia), valvatis. Stamina totidem, corollæ tubo 
inserta cumque lobis alternantia ; filamentis brevibus; antheris sub-2- 
dymis, sæpius exsertis; loculis 2, introrsum rimosis. Germen 2-loculare, 
raro abortu 1-loculare, disco epigyno simplici v. rarius 2-lobo corona- 
tum ; stylo 2-fido v. 2-partito; ramis apice capitato stigmatosis. Ovula 
in loculis solitaria, plus minus complete anatropa v. amphitropa, ad- 
scendentia, ima basi affixa ; micropyle extrorsum infera, raphe ventrali. 
Fructus 2-dymus, carnosus (Eurubia, Didymæu) v. coriaceus siccusve 
(Galium, Vaillantia), abortu nune 1-locularis, extus glaber, hispidus, 
tuberculatus v. longitudinaliter cristato-dentatus (Mericarpæa) ; coceis 
T-spermis. Semen adscendens subpeltatum, intus concavum ; hilo lato ; 
albumine crasso corneo ; embryonis curvi radicula infera. — Herbæ, 
basi raro frutescentes, plerumque scabræ, hispidulæ v. aculeatæ ; ramis 
sæpius #-gonis ; foliis oppositis ; stipulis interpetiolaribus foliis confor-

formibus (Didymeæa) ; floribus (parvis) i in cymas axillares terminalesqué 
plerumque valde compositas, nunc contractas, dispositis, exinvolueratis 
(Eurubia, Didymea, Mericarpea, Galium), v. singulis bracteis # invo- 
lucratis (Relbunium), rarius 3-nis, pendulis ; singulis bractea accretà 
eymbiformi inclusis (Callipeltis) v. pedicellis connatis decurvis in-
