Maiacoa, Griffith. — Dibtrib. Borneo. 



Stems stout, leas tufted than in others, forming an impenetrable jungle. Leaves 

 18-20 ft. ; petiole half the length of the blade, stout, flattened above ; spines short, 

 white, fascicled ; leaflets equidistant, alternate, 2 ft. by 2| in., subulate-acuminate, 

 tip and margins setose, costae of upper leaflets bristly on the upper surface. Spadito 

 8-12 in., crowded with cylindric spikes 6 in. long ; male fl. in pairs ; bracteoles 

 villous. Fruit crowded in a formless mass ; scales quite smooth, aspect waxy and 

 shining, margins denticulate, tawny greenish; mesocarp white spongy. Seed broadly 

 turbinate.— Distinguished by habit, direction of the leaflets their bristly costaj and 

 slender short white spines and crowded thyrsiform fruiting spadixes. — Descr. from

Stem very short or 0. Leaves 15-20 ft. ; leaflets approximate in groups of 2-4, 

 and alternate, 2-3 ft. by li-2 in., spinulosely oiliate above the middle, upper con- 

 fluent ; petiole 8-10 ft. and rachis copiously armed with broken spirals of strong 

 subreflexed spines. Spadices several feet long, rachis woolly. Spikes cylindric, 

 villous, 14-2 in. long ; flowers small, rose-cold. Spathes variously ruptured, floral 

 terminated by dense tufts of rose-cold, paleaceous hairs. Frwit in dense heads, 



1 in. long or more, 1-3 -celled j scales brown, tips terminating in a reflexed brittle 

 bristle.— Descr. from Knrz For. Fl. 1. c— " Spadices dimorphic, one male only, 

 with densely tomentose spikes ; the other monoecious very dense-fld. and difficult to 

 make out j each bract I find to correspond to a cluster of 3 flowers, a female between 



2 males or neuters, and with two densely tomentose bracteoles. ' ' — Beccari, Griffith's 

 Z. macrostachya referred to WaUichiana by Beccari (mss.) is a much stouter form, 

 with oblanceolate leaflets and spikes 8 in. long and nearly 1 in. diam. In Griffith's 

 figure of the whole plant (Tab. 178 C) the leaves have not the long tapering filiform 

 tips of Z. WaUichiana.

 Brit. Ind. 17, t. 179; leaflets close set slightly falcate concolorous, tips 

 subulate filiferous, male spadix muoli branched, spikes much longer than 

 their spathes, fern, spadix reduced to few branches each bearing a very 

 large solitary long pedunoled nodding glabrous spike clothed with broad 

 glabrous imbricating bracts.
