Cladium jamaicense Crantz [= Cladium mariscus subsp. jamaicense Kük.]
Description of the genus.
Robust perennials, up to several meters tall; rhizomatous, sometimes with swollen stolons. Culms with few-noded, internodes hollow. Leaves basal and cauline, V-shaped to flat, midribs and margins scabrid, eligulate. Involucral bracts leaf-like, sheathing. Inflorescence terminal or some lateral, paniculate; partial inflorescences anthelate. Spikelets numerous, short stalked or sessile. Glumes few to many, spirally arranged, persistent, increasing in length, with 2-3 upper glumes fertile. Lower floret mostly functionally male, upper florets bisexual. Perianth absent. Stamens 2-3. Style 2-3-fid, with a thickened persistent base. Nutlets ovoid, with a thick corky beak, surface smooth to wrinkled. Embryo small and poorly developed, broadly obovate in outline, with a basal, poorly developed root cap and without a leaf primordium.
Distribution and ecology.
Cladium is a cosmopolitan genus ( POWO 2022). It grows in estuaries, freshwater wetlands, and lake margins up to 1500 m in elevation. In Madagascar, it is only known from the north where a single taxon, i.e. Cladium mariscus subsp. jamaicense (Fig. 5 View Figure 5 ), has been recorded in the Sava region of Antsiranana province.
