The ovary appeared perfectly one-celled in the rather advanced stage of the only 
inflorescence; and the ovules were all erect from the base of the ovary; but it is 
possible that a partial or complete partition exists at an earlier stage. It is not easy 
to get a good section of the ovary, as the walls are full of raphides and the cavity full 
of mucilage, in which the ovules are imbedded.

We are unable to separate M. borsigiana from M. deliciosa. Engler (J. c.) says of 
the former :——“ Species spe cum precedente [i.e. WM. deliciosa] in hortis commutata, 
sed foliorum petiolis levibus atque lamina multo minore foraminibusque paucioribus 
perforata diversa.” The petiole of Monstera deliciosa he describes as with “ geniculo 
late crispato-marginato.” Among the cultivated specimens in Kew Herbarium, attested 
as being from the same plant by Mr. N. E. Brown, are leaves both with and without 
the appendage to the petiole.
