94 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
numerous, narrow, equidistant,  subtricostate, concolorous on both surfaces. Male 
and female spadices flagelliform, up to 2-3 m. in length, with many remote partial 
inflorescences; primary spathes split longitudinally and then open, fiat, broadly 
linear, longer than their respective partial inflorescence. Fruiting perianth shortly 
pedicelliform. Fruit very small, pisiform, 7 mm. in diam. 
N. E. India. 
94. Calamus nitidus Mart.—Slender. Leaves 60-70 em. long. Leaflets lanceo- 
late, closely equidistant, concolorous, on the upper surface the mid-costa and two 
slender nerves on each side of it bristly, beneath the  mid-eosta only spinulous. 
Male and female spadices very slender with many partial infloresceuces and a 
very slender flagellum at their summit; primary spathes open and flat during 
the anthesis, broadly linear, somewhat longer than the inflorescences. Fruiting perianth 
shortly pedicelliform. Fruit very small. 
Tenasserim. 
95. C. platyspathus Mart.—Slender, scandent. Leaf-sheaths armed with subulate 
spines. Leaves short. Leaflets few, inequidistant, very remote, elongate-lanceolate, 
25-30 cm. long, 20-30 mm. broad, with 5-6 rather acute coste, of which the 
central naked and the others occasionally spinulous; the lower surface slightly mealy 
or pulverulent. Male spadiz elongate, very slender, filiform, with few remote 
panicled partial inflorescences; primary .spathes about as long as their respective 
inflorescence, open, flat, laminar, oblong, obtuse or subtruncate at the summit: the 
lowest (in one specimen) 10 cm. long, 13 mm. broad. Male flowers subterete, 
narrow. |. 
Tenasserim. 
96. C. myrianthus Becc.—Apparently scandent and of moderate size. Leaves 
apparently rather large. Leaflets large, elliptic-lanceolate, many-costate, 40-42 cm. 
long, 4-5 cm. broad, naked on both surfaces or very sparingly spinulous on the 
main cost, green above, mealy-whitish beneath. Male spadiz elongate, slender, 
with many remote punicled-pyramidate, 15-20 cm. long partial inflorescences ; 
primary spathes apparently very narrow, elongate, lacerate; spikelets very dalveate 
and small, the largest, 12-15 mm. long with 8-10 very small trigonous acuminate 
flowers on each side. . 
Tenasserim. 
| 97. C. hypoleucus Kurz.—Apparently slender. Sheathed stem 7-8 mm. in diam, 
Leaf-sheaths armed with unequal, broad-based, subulate spines. Oerea short, Hanba- 
nous, truncate. Leaves short (in one specimen 45 cm. long); petiole short; leaflets 
flaccid, papyraceous, few, very distinctly grouped with long vacant spaces interposed 
elliptic or oblong lanceolate, 15-16 em. long, 8-3-3 em. broad, green above and 
white beneath, with 7-9 -slender costæ, these naked on both surfaces. Female spadis 
very shorť and compact (15 cm. long in one specimen); primary spathes concave- 
cymbiform, elliptic, thinly papyraceous and exsuccous, imbricate, and similar to those 
of a Demonorops sect. Cymbospathe ; partial inflorescences small, shorter than ifii 
respective spathes; spikelets very small, the largest 19-15 mm. long, few-flowered 
and with a strongly zig-zag sinuous, slender axis; flowers 2 mm. long, ovate aeute, 
Burma.
