64 ANNALS OF THE ROYAL BOTANIC GARDEN, CALCUTTA. 
SYSTEMATIC CONSPECTUS OF THE SPECIES. 
GROUPS I-X.—Leaves never cirriferous. 
ji XI-XIII.—Leaves shortly cirriferous with diminutive leaflets at their 
summit or very exceptionally not cirriferous, 
à XIV-XV.—Leaves distinctly cirriferous. 
GROUP XVI.— Anomalous. 
Group I.—Leaves not cirriferous (viz., with rachis not. prolonged into a filiform 
aculeate appendix). Leaflets many, elongate. Primary spathes elongate-tubular, dilated 
and lacerate in their upper part. Spadiz with the partial inflorescences and spikelets 
provided with a pedicellar part which remains included in their respective spathes. 
Fruiting perianth explanate (not forming a pedicel to the fruit) Involucrophorum of 
the female spikelets short, not pedicelliform. Seed with ruminate albumen; embryo 
basilar or nearly so. 
A.—Stem erect. — Leaf-sheaths not flagelliferous. 
7. C. erectus. : 
B.-—Scandent. ^ Leaf-sheaihs flagelliferous. 
2.. C. Flagellum. 
Group ll.—JZeaves not cirriferous. Leaflets numerous, elongate, Pii ary spathes 
elongate-tubular, more or less lacerate in their upper part. Fruiting perianth explanate, 
Jnvolucrophorum short, not pedicelliform. Seed (where known) with equable albumen 
and basilar embryo. : 
A.—Spikelets not inserted at the bottom of their respective spathes and therefore nol or 
very shortly pedicellate, | ; 
T Not scandent.  Spadix not flagelliform, and armed only with straight. 
spines (not clawed). 
3. C. arborescens, 4. dongnaiensis. à 
Tf Seandent.  Spadix flagelliform, clawed on the axial parts between 
ihe partial inflorescences. 
5. C. longisetus, 6. Thwaitesii, 7. rudentum, 8. leptospadix. 
B.—Spitkelets inserted at the bottom of their respective spathes and provided with a distinct 
pedicellar part. Not scandent. padis not flagelliform. ^ Leaf-sheaths mot flagelliferous. 
(The species of this group appear related to those of Group XIV, which, how. 
ever, have cirriferous leaves.) 
9. C. dilaceratus, 10. castaneus, TT. Griffithianus, 12. Burekianus. 
Grove III.— Leaves not cirriferous. Leaflets narrow elongate.  Leaf-sheaths flagelli- l 
ferous. Spathes (primary and secondary) elongate-tubular, strictly sheathing. Spadis 
elongate flagelliform. Spikelets not inserted at the bottom of their respective spathes 
by means of a pedicellar part. Lnvolucrophorum almost stalked, attached to the bottom
