26 ANNALS OF THE KOYAL BOTANIC GARDEN. CALCUTTA.
or at least more slender than the female ones, witli well formed calyx and corolla and
6, usually sterile stamens and an abortive ovary. Fruii globose, ovoid or ellipsoid, more
or less distinctly beaked and usually crowned by the recurved stigmas; pericarp thin,
crustaceous, clothed with appressed, deflexed, imbricating, polished, hard scales. Seed
solitary, globular or somewhat depressed, usually enveloped by a sweet, acidulous or
Qiucilagineous integument, always more or less finely pitted; albumen deeply ruminated,
i t s chalazal fovea usually indistinct and punctiform, sometimes represented by a narrow
furrow, very seldom pit-like. Emhryo always basal.

Spadix ( a o d $) elongated, narrowly eylindraceous before flowering, then move
or less diffusedly branclied. Outer spathe not completely enclosing the inner ones
iind not contracted at the apex into an elongated beak.:
A. Leaf-sheaths armed with isolated or confluent spinas, not with annular s}iiouUßrous
crests. Printury spalhes of male and female ispadiucs coriaceous, iubular before the
anthesis, aflerwarda open flat. Male flowering f anide very narro to, strict, ctcpressiform.
1. Spathes narrow and long, produced at the apex into a tail-like
b r i s t ly tip ; the inner ones usually shoitly protruding beyond the
outermost ; the latter covered with slender acicular spines. (In
D. Loherianus the outer spathe is a good deal shorter thau the
others, as in the following group.) Mouth of the leaf-sheaths not
