of the branches and upper part of the main rachis heteromorphous ; 

 leaves of the lower plane erecto-patent, imbricate on the branchlets, 

 somewhat remote on the principal rachises; of the branchlets ovate-oblong, 

 to r/2 mm. long and J /2 as broad, bluntish, straight or slightly falcate, 

 nearly equal-sided, spuriously veined beneath, more or less slightly and 

 obliquely cordate at the base or the upper base rounded, the upper edge 

 minutely denticulate, the lower edge entire, or denticulate at the very base; 

 of the penultimate rachises similar but somewhat larger, acute or sub- 

 acute, with the lower base slightly produced and lacerato-denticulate ; 

 leaves of the upper plane erected, adpressed ; of the branchlets subfalcate- 

 ovate, crowded, to 1 mm. long, acute, minutely denticulate, oblique at the 

 base, the inner base rounded or rotundate-cuneate, the outer base cordate, 

 much produced, subciliolate ; of the penultimate rachises similar but 

 somewhat larger, denticulate. Spikes very numerous, square, 2 30 mm. 

 long, 1 IVi mm. diam.; sporophylla ascending, finally subspreading, ovate, 

 acute, keeled, minutely denticulate; macrospores probably lentiform and 

 provided with an equatorial wing; microspores yellowish or pale-orange, 

 provided with scattered, conical, tuberculiform or subcylindrical projections 

 on the basal side. - - The description is taken from a specimen from 

 Amboyna, cultivated in the Buitenzorg Gardens.

Shoots probably erect, the lower part simple, very slender, terete, 

 stramineous, the upper part pinnately decompound, the rachises deciduously 

 pubescent; ultimate branchlets 2 3 mm. broad including the lateral 

 leaves. Leaves of the stipe erect, isomorphous, distant, thin, lanceolate, 

 2 mm. long, acute or shortly acuminate, produced and auriculate-cordate 

 on one side at the base; leaves of the branches heteromorphous; lateral 

 leaves subfalcate-oblong; of the branchlets subspreading, to !V a mm. long, 

 Vs as broad, blunt or bluntish, spuriously veined, the upper edge minutely 

 denticulate except at the apex, the lower edge sometimes sparingly den- 

 ticulate, the base rounded or rotundate-truncate ; intermedial leaves erect; 

 of the branchlets imbricate, small, acute or shortly acuminate, minutely 

 denticulate, the base obliquely rounded or rotundate-truncate, produced 

 on the outer side. A specimen occurring in the Buitenzorg Herbarium, 

 considered by Hieronymus as a variety of this species, has the spikes
