2 0 CONSPECTUS OF THE SECTIONS OP THE GENCTS.
Section I/. Chamydoba/anus.—Spikes erect; male flowers, styles and leaves as in
Pasania. Involucres ovoid or globose, externally zonate or tubercular, closed and
enveloping the whole glaus (except the apes in confragosa and Blmieana), but not adnate
to it exce^jt at the base; the glans escaping from the cupule when ripe.
Section VI. ¿/í/?o carp i/5.—Spikes erect; styles and leaves as in Pasania. Involucres
large, thick, woody, ovoid or sub-globose, concentrically or obliquely zonate, or tubercled,
completely enveloping the glans (except in costata and rohmdaia, where the apex is naked),
and more or less adhering to it, not dehiscent; pericarp of glans osseous or granular, not
polished where adherent to the involucre.
