CyperuSy a. good deal resembles Sparganium in its perianth, whilst in 

 the strncture of the flower, ovary, ovules, and seeds is unlike any known 

 to me. In T, Jenmaniy of which flowers only are seen by me, I find 

 sometimes one ovule in each cell with a long funicle, at others 3 super- 

 posed and sessile. In T, splicer ocephala^ of which I have seen fruits 

 only, I find one seed only, or one abortive ovule in each of the cells, 

 which are separated by septa of extreme tenuity. T^ie abortive ovules 

 of this species present the curious appearance figured at t. 1407, f. 7, 

 The mature contents of the cells, figs. 8 and 9, are most curious, and 

 resemble nucules with an enclosed pendulous seed ; repeated examina- 

 tion of them obliges me to regard them as seeds in which the albumen, 

 clothed in a thin integument, hangs freely from the top of the cavity 

 of the cartilaginous testa, which is produced into an apical and basal 

 rigid barbed spine. Materials are, however, wanting for tracing the 

 development of the ovary, fruit, and seeds, and thus explaining satis- 



torlly their structure.
