Machaerina mariscoides


Leaves as long as or overtopping the stems, coriaceous, equitant, ensiform, gradually narrowed upwards and shortly acuminate, more or less asperous to almost smooth, 7-12 mm wide, the cartilagineous margins often brown. Stamens 3; Panicle erect, oblong, narrow, loose, consisting of 5-6 distant fascicles of branches, 20-40 cm long.

New Guinea present, Pacific present: Marquesas (Marquesas present), Papua present, Society Is present, Solomon Is present, W. New Guinea present
Pacific (Hawaian Is., Mariannas, Carolines, Solomon Is., Marquesas, Society Is.), in Malesia: New Guinea (W. New Guinea: Depapre, Jappen-Biak; NE. New Guinea: Morobe Distr., Mt Sarawaket; Papua: Misimi I.).


The specimens from the Hawaiian Islands (Cladium meyenii) have remarkably vesiculousasperous stems and leaves. Plants from the other Pacific islands and also those from New Guinea (Baumea mariscoides = Cladium gaudichaudii) are usually much less asperous to almost smooth. As they agree with Cladium meyenii in the shape of the panicle, the 1-flowered 5-6 mm long spikelets with acute glumes, and shape and size of the nut, I have followed BLAKE (1948) in treating them as conspecific with the Hawaiian plants. See also under M. glomerata.
