GENERAL REMARKS ON THE

formed of two confluent bracteæ, as is certainly the case with respect to the calyptra of Pilcanthus, and of a nearly related genus of the same natural family. This account of its origin in Eucalyptus, however, is hardly consistent with the usual umbellate inflorescence of that genus; the pedicelli of an umbel being always destitute of bracteæ; and in Eucalyptus globulus, where the flowers are solitary, two distinct bracteæ are present as well as a double operculum. But a calyptra analogous to that of Pileanthus exists also in most of the species of Eucalyptus, where it is formed of the confluent bracteæ common to the whole umbel, and falls off at a very early period.
