Z. wallichiana. ZALACCA. 83 
Osservations.—It has the leaflets white beneath and the fruit covered with 
scales having upturned spinulous tips as in Z. -edulis and Z. vermicularis, but is 
distinguishable by its fascicled leaflets and especially by the male spikes having 
the spathels individually distinct, at least at the flowering time, and not connate 
by their margins so as to form circular rings round the axis—a character which 
I have not found in any other Zalacca known to me.

Description.—Tufted, almost stemless and soboliferous like Zalacca edulis and 
allied species. Leaves large, about 5 m. long on the whole, the petiolar part 
alone being 2 m. or more long, armed with terrible, flattened, long acuminate, 
rigid, light-coloured, 4—8 cm. long spines, spreading or slightly deflexed, several 
united by their bases and encircling the petiole with more or less, broken spirals ; 
the rhachis similarly armed in its lower part, but. the spines become less 
numerous as they ascend, and finally solitary above. Leaflets distinctly unequidis- 
tant, approximated in groups of 2—4 on each side of the rhachis and divergent 
from their bases in every group, oblong-lanceolate, broadest in their upper third 
part, above this slightly falcate and abruptly acuminate, terminating in a more or 
less elongate linear-fili-form tip ; below they taper gradually to a rather narrow 
slightly sigmoid or straight base; they are 3-costulate green and almost glossy 
on both surfaces, but slightly paler underneath ; the mid-costa, though at times 
slightly spinulous towards the apex, is hills smooth, as are also the side 
costae ; margins spinulous, ciliate from above the middle or thereabouts ; the 
interniodiato leaflets are 65—70 em. long, and 8—9 em. wide; the upper are 
shorter and more distinctly sigmoid-faleate ; some at the apex are confluent ; the 
lower leaflets are the narrowest and have a more long-acuminate filiform tip than 
thé upper. Male spadix coming forth as usual from the axilla of the lower 
leaves, is elongate, nodding or recurved, branched from the base or divided into 
several secondary and tertiary flaccid and pendulous spike-bearing branches, 30—80 
cm. long; primary spathes elongate-lanceolate, acuminate, covered with a thin
