Calamus spp. is a “Solitary or clustering, stemless to high-climbing or erect pleonanthic dioecious rattans; sheaths usually heavily armed with spines, the spines frequently highly organised. Flagellum (sterile inflorescence) often present, borne on the leaf sheath, sometimes absent and replaced by a cirrus at the end of the leaf, very rarely both present or both absent; knee often present; ocrea sometimes well developed, usually inconsicuous. Make and female inflorescences superficially similar, often ending in a long flagellum, sometimes with gradual succession of branches, often with descrete distant branches (partial inflorescences); bracts always tubular at the base, rarely with broad limbs splitting down one side, but if so, then the base always tubular and unsplit, bracts variously armed; partial inflorescences usually much longer than the subtending bract, very rarely shorter, involucre and involucrophore inconspicuous. Male flower with cup-shaped calyx, usually with 3 well defined lobes; corolla split almost to the base into 3 petals; stamens 6, very shortly epipetalous; pistillode minute. Female flower borne together with a sterile male flower as a pair. Sterile male flower like the fertile male, but with empty anthers. Female flower usually larger than the male, with calyx shallowly 3-lobed; corolla with 3 petals; staminodes 6, joined basally to form a ring; ovary tipped with 3 stigmas and covered with reflexed scales; locules 3 with one ovule in each. Fruit variously shaped, covered in reflexed scales. Seed usually one only, very variable in shape, covered in a thin to thick sarcotesta; endosperm homogeneous or ruminate; embryo basal or lateral. Seedling leaf bifid or pinnate”
