Amaranthacese and Illecebreae, adding some remarks on the carpella 

 of Polygoneae and Alsineae. He indicates certain characters in the 

 flower of Casearia in which it approaches Monotropa, Drosera, and 

 especially Francoa. In Thynielese he finds considerable variation in 

 the position of the carpellura, and states that the relative position of 

 carpelluni and segments of perianthium is the reverse of what takes 

 place in Proteaceaj, the carpellum being always opposite to one of the 

 segments of the perianthium. The tendency to the suppression of 

 stamens in Thymeleae is also the reverse of that of Proteaceae, being 

 on the side opposite to the carpellum. In Pimelea and Lachnsea he 

 states that the carpella are all posterior, while in Daphne the carpella 

 of the two-flowered axillae stand W'ith their backs to each other, or 

 more or less turned towards the stem : Dais is a mixture of these. 

 Lastly, he notices various peculiarities in the ovary of Sassafras offi- 

 cinale, in Sanguisorbeae, in Combretum, in Aucuba Japonica and in 

 Marlea. 



The memoir was illustrated by a lai'ge tabular view of the proposed

On the various Forms of SaUcoriiia. By Joseph Woods, Esq., 

 F.L.S. ; with some additional remarks by Richard Kippist, Esq., 

 Libr. L.S. 



The paper relates almost exclusively to the British species of Sali- 

 cornia, and more particularly to those which occur on the coasts of 

 Sussex and Hampshire. 



The author begins by noticing what he considers as the typical 

 form of S. herbacea. This he describes as always erect, except that 

 late in the autumn, the branches, usually spreading or ascending, are 

 sometimes borne down by the weight of the fruit-spikes. The colour 

 is green, generally glaucous, but never red. The spikes of fruit are 

 cylindrical, 2 or 3 inches long (ten to fifteen times their thickness), 

 and contain from ten to fifteen sets of seeds. 



The second form (S. procumbens, Sm.)^ which is stated to be more 

 common than the first, is described as procumbent, decumbent, or 

 ascending, but always with a bend at the top of the root, and there- 

 fore never erect : the branches and their subdivisions are much shorter 

 and more numerous than in the typical form, and at the same time 

 much more divaricate, the lower ones especially being frequently 

 recurved ; and these lower branches being much longer than the sue-
