D. mirabilis | BECCAPI. THE SPECIES OF DAEMONOROPS. 175 
disposed in 3 almost equal, very remote groups, all in one plane, and not pointing 
in different directions, considerably approximate in each group by their bases, papy- 
raceous, green on both surfaces, elongate-oblanceolate, tapering considerably towards the 
base, broadest above the middle, and thence shortly acuminate upwards to a slightly 
bristly tip, tricostulate, all nerves bald on both surfaces; margins slightly spinulous 
but only near the upper end; the largest leaflets are those of the lowest group, 35—40 
em. long, 3 cm. broad; those of the terminal group are shorter (25 em. long at 
most) and narrower (10-12 mm. broad) being broadest about their middle. Flowers...

HaBrrAT.—North Borneo: on the Lawas River (Burbidge in Herb. Kew.). 
OBSERVATIONS.— The only specimen of this species seen by me is an entire leaf 
with a portion of the sheathed stem apparently gathered from a full grown plant. 
In the disposition and shape of the leaflets it mostly resembles D. Sabut, from which 
it differs in having 2-3 pairs of collars, which form corresponding complete ant- 
harbouring galleries in the upper part of each leaf-sheath, just below the base of the 
petiole; the spines and spiculae radiating from the edges of the collars are probably 
very long and slender, as in the allied species, but none remain on the specimen I 
have examined. 
Prate 72.— Daemonorops annulatus Bece. It represents the entire type specimen 
in Herb. Kew.

Description.—Apparently scandent. Sheathed stem of middling size, 25-3 cm. in 
diameter. Leaf-sheaths slightly gibbous above, each furnished with several pairs (5-6) 
of very broad, complete, membranous, radiately-striate, decussating collars, all equal 
in size, of which each pair contains a gallery quite closed in by the crossing and 
interlacing of the long black spiculae which fringe each half pair; these pairs of 
collars are 10-20 mm. apart; interposed between the broad double collars are 2-5 
single, membranous, horizontal rings, which are also spiculiferous, but form no 
galleries; such single rings surround the lower portions of the leaf-sheaths more 
frequently than the upper; the spiculae of all the collars are criniform, 3-5 cm. 
long, or at times shorter, rigid, brittle, black with a lighter-coloured base; the base 
of the petiole is armed on the back with irregular, interrupted rows of pectinate, 
black-tipped, slender spines; the petiole is 15 mm. broad a few centimetres above 
the mouth of the leaf-sheath, flat on the upper, and convex on the lower surface, 
and has a few pectinate and divaricate spines on the edges which are larger than 
those on the back, Other parts unknown.
