10«. The longitudinal section of the fruit shows the thickness of the calyx-tube, and also its continuity 

 with the Placental column, which is comparatively thin and pointed in this species. It will also 

 be seen that the top of the ovary is depressed towards the centre. Inside and outside -file 

 surface of the calyx-tube is covered with fibro-vascular bundles, more or less reticulated.

10&. Transverse section. The cells are arranged in a cruciform manner, and are narrow-oblong or linear- 

 oblong, scarcely acute. When fresh they are set in a darker outer zone, which forms a Maltese 

 cross in section, and which consists of a pulpy or cellular mass very regularly dotted over with 

 (or embedded in the mass), small kino-fragments regular in size. This colloidal, pulpy mass 

 readily dries up, and forms a powdery substance small in bulk. Each of the four cells are enclosed 

 in a yellow, parcbment-Uke membrane (reminiscent of the membrane of the core of an apple) 

 The membrane is also shown longitudinally at —
