236 Mr. Brown on the Female Flower and Fruit of Rafflesia Arnoldi, 



lantlbus inaequale quasi leprosum, carnosum crassum indehiscens, cavitate placentis 

 undique seminiferis dense repleta. 



Semina subglobosa, pedicello brevi quandoque subnullo insidentia. 



Integumentum exterius crasso-membranaceum subpulposum areolatum cellulis minute gra- 

 nulatis : interius albumine arete adherens. 



Albumen densum, subcartilagineum, aqueo-pallidum, per lentem modice augentem structura 

 quasi radiata, sed magis auctum constare videtur substantia denso semitransparenti 

 alba nee in cellulas manifeste divisa, sed undique farcta corpusculis celluliformibus figura 

 variis, in serie extima majoribus oblongo-obovatis, reliquis miuoribus vix symmetrice 

 positis, omnibus semiopacis e membrana materia minute granulosa repleta formatis. 



Substantia densa Albuminis uniformis forsan e cellulis parietibus incrassatis et obliteratis 

 singulis, nucleo (corpusculo) semiopaco foetis. 



Embryo in centro albuminis parvus subglobosus aqueo-pallidus e cellulis numerosis parvis 

 mollibus, materia minute granuloso repletis, ab albumine facile separabilis, et absque ulla 

 manifesta communicatione cum ejusdem peripheria vel ope suspensorii, v. canalis inter- 

 medio.

Fig. 1. A female flower-bud, with the roots of the Vitis (or Cissm) vertically divided, which 

 shows the numerous irregular cavities of the ovarium chiefly if not entirely above 

 the insertion of bracteae and calyx, and the vascular lines continued from the walls 

 of the cavities through the upper solid part of the column into the axes of the 

 style-like processes : — natural size. 



Fig. 2. A female flower-bud in the same stage of development, the bracteae and calyx en- 

 tirely removed, to show its outward resemblance to the male flower-bud (figured 

 in Linn. Trans, vol. xiii. Tab. XXI.) : — natural size. 



Tab. XXin. 



Fig. 1. A small segment of the column, of which part of the elevated undivided limb is 

 removed, to show the narrow furrows of the sides of the column corresponding 

 in number with the rudiments of antherae, seen in
