Calamus (All the species of this genus)

All the 200 species of this genus inhabit tropical or sub-tropical regions; they are mostly found in Eastern Asia. To those described on page 235, Vol. I., the following should now be added:

C. guineensis (Guinea). l. pinnate; segments narrow-lanceolate, supported by spiny leafstalks; young ones cinnamon-brown, changing to deep green. Sikkim, 1884.

C. kentiaeformis (Kentia-shaped). "The habit of the plant recalls at once the form and character of Kentia Forsteriana [Howea Forsteriana], from which circumstance its name was given" (Catalogue of the Compagnie Continentale d'Horticulture, 1884, p. 3). No further description given. C. Lindeni (Linden's). l. pinnatifid; pinnae unarmed, lanceolate, flat, three-nerved, acuminate, attenuated at base, white-pruinose beneath; petioles and sheaths prickly, the prickles straight, long, brown, thickened at base. Caudex thickened, cylindrical. Indian Archipelago, 1883. (I. H. 1883, 499.) C. regis (royal). l. shining green, borne on mealy petioles. 1886. An elegant and graceful Palm.

C. spectabilis (remarkable). l. slender, pinnate; pinnae about five on each side the rachis, not equidistant, oblong, five to seven-nerved, convex above; petioles very short. 1886. A small-growing, somewhat spiny species, of graceful habit, suitable, when in a young state, for table decoration. C. trinervis (three-nerved). l. pinnate; leaflets alternate, lanceolate, sessile, acuminate, having three prominent, hairy nerves, and two marginal and two intermediate ones less developed; transverse veins conspicuous; petioles thorny, clothed with a deciduous, scale-like tomentum, the sheath ending in a fringe of pointed, brown scales.
