76 GENERAL REMARKS ON THE 



formed of two confluent bracteae, 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 bracteae ; 

 and in Eucalyptus globulus, where the flowers are solitary, 

 two distinct bracteae are present as well as a double oper- 

 culum. But a calyptra analogous to that of Pileanthus 

 exists also in most of the species of Eucalyptus, where it 

 is formed of the confluent bracteae common to the whole 

 umbel, and falls off" at a very early period.
