one-seeded lobes of the fruit ; while in Boragineae the separation is still more 
complete. The division of the five loculi of the ovary of Lhium into ten by spurious 
dissepiments is not so perfect, the projections from the centres of the carpels not 
reaching the central axis of the ovary.

Before passing to the consideration of ovaries in which the ovules are borne by 
the floral axis (/. e. with axial placentation), it should be mentioned that there are 
cases in which the present state of our knowledge does not enable us to decide with

certainty whether the ovules arise from the axis or from the margins of the cirpels 
which have become united to it ; and these doubtful cases are possibly more 
numerous than is generally thought. Payer's observations on Cerasihim and Mala- 
chium show that in Caryophylleae the expanded apex of the floral axis becomes
