420 ox THE FEMALE FLOWEll AND FRUIT OF 



Tab. 23 (XXIV). 



Fig. 1. A ripe pericarpium, of the natural size, the calyx, bracteye and apex 

 of the column being deciduous. 



Fig. 2. The same divided vertically, and showing the thickness of the 

 densely-fleshy and deeply-furrowed covering, and also that tlie whole of the 

 ovarial cavity is above tlie insertion of bracteae and calyx. 



Tab. 21 (XXY). 



Fig. 1. A small portion of the wall of two adjoining cavities, the surfaces 

 covered with numerous seeds, all of equal size : — maguitied 20 diameters. 



Fig. 2. A seed with its funiculus, of which the lower erect portion is filiform, 

 the recurved upper half being of the same texture, colour and surface with the 

 seed, which it somewhat exceeds in thickness : — magnified 100 diameters. 



Fig. 8. The same divided longitudinally, to show the structure of the seed 

 (according to Mr. Bauer), and that the enlarged apex of the funiculus is solid : 

 — magnified 100 diameters. 



Fig. 4. The nucleus of the seed taken out of its thick nut-like outer cover- 

 ing : — magnified 100 diameters. 



Fig. 5. The same nucleus, whose membranous coat is separated by pressure, 

 iSS] to show the albumen: — magnified 100 diameters. 



Fig. 6. The denuded loosely-cellular albumen. 



Fig. 7. A portion of the albumen, exhibiting the embryo, ifs surface and 

 lateral origin, according to Mr. Bauer: — magnified 100 diameters. 



Fig. R. Br. is a longitudinal section of the albumen, exhibiting R. Brown's 

 view of the origin, form, and surface of the embryo. 



Tab. 25 (XXVI). 



Fig. ] . A branch of the Vitis, on which are four very young buds of Hafflesia 

 Anioldi: — natural size. Of these, 



a. (not separately figured) is merely a very slight swelling, caused by the 

 nascent parasite, but before its parts are distinguishable. 



A. (also separately figured, vertically divided and moderately magnified), the 

 youngest parasite whose parts are distinguishable, deeply seated, entirely en- 

 closed, and before its cortical covering corresponds with it in form. 



B. (in like manner separately figured, divided and magnified), in which the 

 parasite is entirely enclosed in its reticular covering. 



C. In which the reticular covering has burst, vertically divided and mac;ni- 

 fied. 



HYDNORA AFRICANA. 



Tab. 26 (XXVII). 



Fig. 1. A flower of Hydnora africana, with its very short base. 

 Fig. 2. The same longitudinally divided :— both of the natural size.
