III, fig. 4). The peduncle is softened and semi-transparent, so that the fibro-va oular bundle 

 can be seen shining through its substance. The lobes of the perianth retain their original 

 size and are well preserved, not showing any signs of softening, but being dried up and of 

 a reddish tint (Plate III, fig. 7). The portion of the axis between the origin of the perianth 

 and the base of the ovary is much softened, and the tissue to a great extent converted into 

 a transparent gelatinous substance in which the bifurcation of the vascular bundle beneath 

 the ovary can be readily seen. The cuticular stratum of the entire ovary is widely separated
