- bracteae concavae obtusae virides in apice juvenile inflorescentiae diu imbricatae, bracts concave blunt green at the young apex of the inflorescence for a long time imbricate.

- bracteae involucrales lineares, involucral bracts linear.

- bracteis intimis indivisis integrisque, with the innermost bract undivided and entire.

- bracteae ad ramificationes oppositae (B&H), the bracts opposite the ramifications [i.e. the places where the branch arises].

- spathae unisexuales, utriusque sexus 2-phyllae, bracteis complicatis, exteriore interiorem amplectente (B&H), spathes unisexual, both sexes 2-leaved, with the bracts folded together, the exterior one clasping the inner one.

- spathae unisexuales, diphyllae, bracteis a basi liberis, utriusque sexus l-florae (B&H), spathes unisexual, diphyllous, with the bracts at the base free, both sexes 1-flowered.

- flores ad axillas bractearum membranaceo-scariosarum breviter pedicellati (B&H), flowers in the axils of membranaceous-scarious bracts shortly pedicellate.

- bracteae nunc ovatae distichae, nunc angustae deciduae (B&H), bracts sometimes ovate, distichous, sometimes narrow, deciduous.

- pedunculi axillares, solitarii, 1-flori, bracteis paleaceis stipati (B&H), peduncles axillary, solitary, 1-flowered, enclosed by chaffy bracts.

- bractea appendiculam stipitiformem includens (B&H), the bract enclosing the stipe-shaped appendage (B&H), bract encompassing a stipe-shaped appendage.

- bracteae sub cymis nunc ovatae subimbricatae diu persistentes, nunc caducissimae minimae v. 0 (B&H), bracts below the cymes sometimes ovate, somewhat imbricate, lasting a long time, sometimes very caducous, very tiny or none.

Bractea involucralis (adj.B), abl. sg. bractea involucrali: involucral bract, (in bryophytes): “a sheath of foliar origin, derived by a fusion of the bracts surrounding a perianth” (Magill 1990).

NOTE: B&H (Compositae): flores involucro communi (periclinio Auct. plur.) e bracteis {squamis, phyllis v. phyllariis Auct. plur.) 1- [infinity sign] -seriatis liberis concretisve cincti, flowers surrounded by a common involucre (the periclinium of many authors), from bracts (scales, leaves or phyllaries of many authors) 1-indeterminately-seried, free or compound [fused together]; see phyllary, phyllum,-i (s.n.II), squama,-ae (s.f.I).

NOTE: tegula,-ae (s.f.I), abl.sg. tegula: tegule, an involucral bract of the involucre in the Asteraceae (Compositae), involucral scale, phyllary.

NOTE: valvulae (pl.f.I), valvulae (valvula) = “the bracts of Sedges” (Lindley).
