Stemless, soboliferous, armed palms. Leaves piunatisect, not 

 flagelliferoiTS. Leaflets narrowl}- linear-lanceolate. 



Spadix iuterfoliar. pendulous, flowering branches catkin-like. 

 Spathes persistent ; lower sheathing, incomplete ; bracteoles 

 cupular, 2-celled ; flowers coriaceoiis, densely crowded, polygam- 

 ous. Male flowers : calyx tubular, 3-fid ; corolla tubular, segments 

 valvate; stamens 6, anthers short. Fe-male flowers larger; peri- 

 anth accrescent ; calyx trifid ; corolla-lobes lanceolate, valvate ; 

 staminodes 3-6 ; ovary 3-celled, stigmas 3, subulate ; ovules 

 basilar. 



Fruit globose or obovoid, 1-3-seeded, clothed with reversed or 

 spreading scales. Seeds 1-3, erect, top excavated ; testa 

 crustaceous ; outer coat fleshy ; albumen equable ; embryo sub- 

 l)asilar. 



Species 10. — Indo Malayan. 



Gvltivafion in Europe. — The species of this genus are stove 

 plants. They thrive in strong loam and river sand, in moist heat. 

 The pots must be well drained to prevent any stagnation. 



ZALACCA SECUNDA, Griff, in Calc. Journ. Nat. Hist. Y, 12; 

 Palms Brit. Ind. 14, t. 177 ; Becc. Males. Ill, 673. — Calamus colltnuf, 

 Griff. Palms Brit. Ind. t. 186 (leaf only). 



This species is very imperfectly known. Grifllth describes the 

 male spadix before the opening of the flowers and gives the figure 

 of an incomplete leaf, whilst Hooker was in possession of a leaflet, 

 a young fruit, and some ripe fruits in a broken condition. 



Leaves 30 feet long ; leaflets 33 inches long, nearly 3 inches 

 broad, straight, coriaceous, concolorous, with 3 stout costae acute on 

 both surfaces and spinulose beneath, margins setulose above the 

 middle.
