88 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. [D. Lewisianus. 
spines (Grifith’. Spadices approximate to the apex of the stem, before flowering 
fusiform-elliptic and moderately or shortly beaked, axillary in appearance, erect, 
supported on a short pedicel (1 em. long) which is more or less prickly on the dorsum 
and at the margins; outermost spathe cymbiform, furfuraceous, two-keeled, narrowed 
into a beak, which is half the length of the body and is armed with narrowly 
laminar, subulate, elastic, rather long, blackish, not very crowded, solitary spines, 
often so slender as to become bristly; second spathe slightly spinous along the two 
keels; the others glabrous and of a cinnamon colour. Male spadiz (when not 
enveloped by the spathes) densely panicled, thyrsoid; rusty-furfuraceous on the 
axial parts, with about five branches (partial inflorescences), each 5-6 cm. 
long, decompoundly divided ^ into branchlets which bear 3-4 very small 
spikelets on each side; secondary  spathes amplectent; spikelets very short, 
rarely more than 1 cm. in length with very few flowers (3-6 in all); 
spathels amplectent, bracteiform, very slightly prolonged at one side, obtuse or 
slightly apiculate; involucre  cupular, exactly truncate, the third part of the 
length of the calyx, more or less distinctly 2-toothed on the side next to the 
axis, teeth ciliate. Male flowers comparatively large, 6-6°5 mm, long, 2:5 mm. 
broad,! oblong, obtuse; the calyx tubular-campanulate, very superficially 3-toothed, 
its margin ciliate-furfuraceous, especially on the apex of the teeth; the corolla 
twice as long as the calyx, or longer, divided two-thirds down into three 
oblong-lanceolate, rather obtuse segments; stamens with filaments connate 
together for about two-thirds of their length, rather thick and subulate in the free 
part; rudimentary ovary very small Female spadiz (when not enveloped by the 
spathes) short, densely panicled, with 4-5 small partial inflorescences; the joints of 
the main axis furfuraceous, the lower ones short (10-12 mm. long’ and 
tumescent from midway down, the upper slender and more elongate; partial 
inflorescences very short, with only 2-3 alternate spikelets on each side ; 
secondary spathes bracteiform, awplectent, acuminite, very finely veined; spikelets 
very short with a sinuous axis and 5-6 distichous flowers in all; spathels 
bracteiform, amplectent, acuminate, finely striate; involucrophorum rather thick, 
about 3 mm. long with a distinct axillary callus and a deep transverse fovea, 
expanded at the apex into a sub-spathaceous and unilaterally acute limb; 
involucre cupular, rather deep, about the third part of the length of the calyx, 
truncate, entire or very obsoletely  2-dentate, finely  striately-veined externally ; 
areola of the neuter flower orbicular, with a semicircular swelling on its upper 
margin. Female flowers ovate, 6 mm. long; the calyx urceolate, very superficially 
3-toothed, rather strongly striately-veined externally; the corolla longer by one- 
third than the calyx, ventricose in the part included in the calyx, divided down 
almost to the base into three segments which are suddenly narrowed from the middle 
upwards into a lanceolate point; staminal urceolum crowned by six short apiculate 
teeth; anthers small, sagittate; ovary globular; style short and thick; stigmata 
eircinate, revolute. Fruit apparently small, globular, very suddenly beaked, 12 mm. 
in diameter (not quite mature); scales in 15 series, channelled along the centre, 
straw-yellowish, shining, with a broad, pale, erosely-denticulate margin, and 
a 
dark spot on the very obtuse point.
