ZALACCA (said to be the name of this genus in the Moluccas). Sometimes spelt Salacca. ORD. Palmae. A genus comprising about eight species of stemless, stove Palms, with soboliferous roots; one is a native of Assam, and the rest inhabit the Malayan Archipelago. Flowers often pink, polygamo-monoecious or dioecious; spathes persistent, the lower ones sheathing the peduncle and branches, incomplete, the partial ones subtending the floriferous branchlets; spadices simple or fastigiately branched, pendulous, the floriferous branchlets catkin-like, rather short, remote or clustered, sessile or pedunculate; bracteoles connate in a two-celled cup. Fruit globose, turbinate, or ovoid, one to three-seeded, usually beaked. Leaves elongated, equally pinnatisect; segments alternate, fastigiate or equidistant, lanceolate or oblanceolate, straight or falcate, acuminate; rachis obtusely triangular, not produced into a spine; petioles slightly terete, armed with often spirally-disposed prickles. The best-known species are here described. The plants grown in some nurseries under the names of ZALACCA nitida and ZALACCA Wagneri perhaps represent distinct species, but so little is known about them that they cannot be described. The cultural directions given under Cycas are applicable to this genus. ZALACCA Blumeana (Blume's). A synonym of ZALACCA edulis. ZALACCA edulis (edible). fl., spadices drooping, long-branched, the males axillary, longer and more branched than the females; female catkins 2in. to 3in. long, thicker than the males. fr. fulvous-fuscescent, pyriform, 2 1/2in. long. l. copious, clustered, erect, clothed with long, often serrate prickles; pinnae linear-lanceolate, very long-acuminate, 1 1/2ft. to 2 1/4ft. long, 1 1/2in. to 2in. broad, whitish beneath; petiole rather shorter than the rachis, and armed with robust prickles. Malay Archipelago, 1847. SYN. ZALACCA Blumeana. ZALACCA Wallichiana (Wallich's). fl., spadix axillary, many feet long, drooping or pendulous, long-branched; male catkins 1in. to 2in. long, the female ones cylindrical, 2in. long. fr. ovate-pyriform, 1 1/2in. long, slightly acute. l. 18ft. to 20ft. long, clustered, nearly erect; pinnae fascicled in twos, threes, or fours, narrow-lanceolate, with a long and slender, cuspidate point, attenuated and reduplicate at base, flat, the older ones 1 1/2ft. long, 3in. to 4in. broad; petiole 4ft. to 6ft. long, armed with robust, fuscous prickles. India, &c., 1847. (G.C.1873, p.1803.)
