apex, where they abruptly and symmetrically taper into a long filamentose 
tip ; the margins minutely spinulous from the middle upward, the 
spinules becoming closer near the apex; transverse veinlets very sharp 
and prominent on the upper surface, much less visible underneath; the 
mid-costa almost equally prominent on both surfaces, smooth and ac- 
companied on each side by several unequal, slender, parallel, secondary 
nerves, of which one, lying nearer to the margin, is often stronger than 
the others, especially near the base, where the leaflets may be called 
subtricostulate ; but these side costae evanesce upward. Male spadix 
apparently short, with several approximate short branches; each branch 
being subtended by a primary spathe and bearing 6 to 8 approximate 
spikelets; the primary spathes are covered with a tenuous, rusty, soft 
indumentum, are marcescent and much lacerated or split longitudinally, 
and reduced to several strips and filaments. Male spihelets when in 
flower cylindraceous, slender, 5 to 7 cm long, 10 to 11 mm broad, borne 
on a very short pedicel, which is embraced by a short and broad, mem- 
branaceous, bracteiform secondary spathe; the spathes are not connate by 
their margins and they do not form an annular involucre, as is usual 
with the other species, but are individually distinct, bracteiform, concave, 
very broad, acute, and striate, each bearing two flowers; bracteoles small 
woolly-ramentaceous. Male flowers small, slightly longer than the spathe- 
lets, 4 mm long; calyx split to the base into 3, linear, thinly mem- 
branaceous or subhyaline, striate segments ; the corolla is slightly longer 
than the calyx, three-parted nearly to the middle, and tapering below, its 
segments are short, oblong; stamens united to the corolla as far as the 
base of the segments ; anthers oblong, obtuse.

In its leaflets being whitish beneath, this species approaches Zalacca Blumeana, 
Z. edulis, and especially Z. vermicularis, but it differs from these as from all 
the other species known to me, in the spathes and the male spikes, which are 
individually distinct, and are not connate by their margins to form a compound 
annular spathe.
