 Professor Babington describes in the ' Gardeners* 

 Chronicle,' 1844, p. 557, a curious flower of Cerastmm^ 

 in which, in addition to other changes, the five carpel- 

 lary leaves " were partially turned in without touching 

 the placenta, which bears a cluster of ovules, and is 

 perfectly clear of all connection with those partitions"

FlO. 51. 1. Monstrous flower of a Ceradium ; sepals and p*tals

 imperfect dissepiments and the attachment of the ovules. 4. A deformed 

 ovule. 



M. Baillon- records flowers of BuniaS', some with 

 ovules on the margins of the carpels, others with a
