into very fine upeurved brittle points, 4—5 mm. long; the remnants of the style 
form, on the round top of the fruit, a small muero about 3 mm. long, surrounded’ 
` and entirely hidden by the erect spinules of the uppermost scales. Seeds 3; when 
divested of their fleshy integument roundish subtrigonous, 2 cm. long, 15—18 mm. 
broad, 10—12 mm. thiek, rounded above, narrowing towards the base, convex on the 
back and having two flat facets inclined at a wide angle on the inner side and 
an  aplcal pit, corresponding to a narrow intrusion of the integument, about 
8 mm. deep; the embryo is basal, exactly in opposition to the apical pit. and 
about as long asthe intrusion of the integument. 
Hanrrar.—The specimens from which the above description has been drawn dp, 
are derived from plants cultivated in the Botanic Garden of Buitenzorg (V. Y. 8 
the fruit; V. Y. 8a the male spadix), but apparently introduced into the Garden 
from | its neighbourhood, where this species seems to be either spontaneous or 
occasionally planted. 
OnBSERVATIONS.—li is characterized with certainty by the male spadices short. 
cupressiform, having few approximate secondary branches, each bearing only 1—2 
finger-like thickish spikes, shorter or else slightly longer than their respective large 
fusiform spathes; by the same spikes having the flowers very closely packed together, 
completely hiding the spathels, and by the segments of the corolla slightly divari- 
eating during the anthesis, and not completely spread out; by the leaves having 
the leaflets ashy grey beneath, interruptedly pinnate, but with the leaflets in each 
group regularly bifarious and not pointing in different ways. It seems also to differ 
from the allied species by the fruit, which is not much prolonged at the base, and 
has subtrigonous seeds, convex on the dorsum. 
The fruits of Z. Blumeana represented in Martius’s plates 123 and 159 III, 
show the scales not prolonged into subspinous upcurved points, doubtless because, 
being very brittle, they had been rubbed off before the artist saw them. Calamus 
Zalacca Gaertn. is, I think, referable to Z. Blumeana Mart., and is not the plant 
of Clusius (Z. edulis Reinw.), especially on account of the relatively scanty, although 
fleshy, but later dry integument, with which the seeds of Z. Blumeana are 
covered (demum exarescens—Gaertner); whereas in Z. edulis the integument is 
copious and never becomes absolutely dry. 
PLate 46.—Zalacca Blumeana Mart.—Male spadix. Portion of a leaf near the 
end. Spike with mature fruits. One fruit open showing 2 seeds in situ, one 
having been taken out; one seed, dorsal aspect. From plants cultivated at Buiten- 
zorg (V. Y. 8d, and V. Y. 8). Specimens in Herb. Beccari.

It ditfers from the type only in the fruit being almost globular and only very 
slightly attenuate at the base. ‘The fruit contains 1 to 3 seeds, which of course 
vary in shape according to their number, are globular when solitary, convex on 
the back with flat ventral surfaces when two, and have two flat inner facets when 
3 in number, otherwise as in type. ;
