base, gradually acuminate to a long tail-like point, somewhat 
narrowing also towards the base which is rather narrow and 
where the margius are bent backwards, usually they are unicos- 
tate and ensiform, about 40 cm. long and 14-16 mm. broad, 
but sometimes they are bicostate and in this case they are about 
twice as large and narrowly lanceolate, green and dull on both 
surfaces, narrowly, but very distinctly bordered by a rather 
thick nerve, especially on the lower surface; the mid-costa 
is acute above, beneath it is very slender and furnished with 
a few linear scarious scales; secondary nerves slender, tertiary 
nerves scarcely visible, being immersed in the perenchyma. 
Fruiting spadix recurved, apparently about 25 cm. long, divid- 
ed into rather numerous branches, which are irregularly and 
spirally inserted round the axis; the peduncular part of the 
spadix in short; the branches are rigid, thickish, subtrigonous 
in their inferior part, where the flowers are arranged in 3 
longitudinal series, flattened in the remainder, where the flowers 
are biseriate: they are throughout of the uniform thickness of 
3.5-4 mm. Fruits 4-5 mm. apart in each line, small, narrowly 
elliptical, diminishing equally to both ends; their bases acute; 
their apices mammilate and 12-18 mm. long, 6 mm. broad; 
the bract subtending the fruit very short, with a rounded 
margin; the side bracts are very narrow and inconspic- 
uous. Seed elliptical, 9 mm. long, 5 mm. broad, rounded 
above where it is very inconspicuously apiculate, very briefly 
caudiculate, and pungent at the base, the branches of 
the raphe very slightly and loosely anastomosing; albumen 
radiately ruminated, when seen in a cross section, by 12-14

lamellae penetrating almost to the centre. Fruiting perianth | 
shallowly cupular, 4 mm. broad and not quite 2 mm. high, 
truncate and slightly contracted at the mouth.

P. negrovensis ia related to P. rigida, but is distinguished | 
by the narrower, slightly falcate and more distant leaflets; by 
the spadix having more numerous branches, and these more 
slender, not trigonous throughout, but distinctly flattened from 
the middle upwards; by the flowers being 3-seriate in the lower -
