Figs usually axillary on normal leafy stems, rarely cauliflorous, interfloral bracts usually present, internal bristles sometimes present, apical pore with interlocking bracts, circular with 2 or 3 bracts visible or upper bracts descending and aperture slit-shaped or 3-radiate; peduncle with 3 basal bracts in a collar; lateral bracts usually absent. Male flowers: dispersed or around apical pore; stamen 1(or 2); pistillode usually absent. Female flowers: stigma usually simple, filiform, mostly conspicuously papillate.
