Viola yag-ixata Maximowicz. (PL IX, fig. 18.) 



Seed with rather fine close pits ; at irregular intervals the 

 •surface is raised into ohscure swellings, elongate longitudinally, 

 which can scarcely he described as tubercles. Two seeds and some 

 broken fragments. 



Length = 1 - 75 mm. ; breadth =1*1 mm. 



In size and shape, character of pitting, and character of these 

 tubercles, the fossil agrees with the Japanese species V. vaginata 

 (PL IX, fig. 19). 



Viola sp. ( = Tegelen sp., 1907, pi. i, fig. 22). (PL IX, fig. 20.) 



Length = I '1 mm.; breadth = "8 mm. 



In ' The Fossil Flora of Tegelen ' we described a Viola seed 

 showing longitudinal flutings. A specimen from Castle Eden 

 shows the same flutings, but in a more marked degree. The seeds 

 agree in size and shape, and in the character of their cell-structure. 

 The fluting appears to be a specific character, and not the effect 

 of under-development. Under-developed or unripe seeds collapse 

 and crumple ; they do not remain inflated and become fluted. 



Except these two seeds, I have seen none, either fossil or recent, 

 that show this peculiar character. 



HALOKRHAGACE.E. 



Hippuris vulgaris Linnaeus. (PL IX, fig. 21.) 



Length=l'3 mm. ; breadth=: - 5 mm. 



A single specimen agrees in every way with the recent species 

 H. vulgaris, a plant which at the present day inhabits the whole 

 Northern Hemisphere and South America. 



ARALIACE^. 

 Aralia cord ata Thunberg. (PL IX, fig. 22.) 



Endocarp oval, somewhat flattened ; ventral margin slightly 

 convex; dorsal margin convex; style ventral, subapical; attachment 

 basi-ventral ; surface rough, with very coarse hexagonal pits 

 elongate transversely, and the remains of a rough, crumpled, outer 

 coat. 



Length = P6 mm.; breadth = l mm. 



The general shape and character of the coats of this specimen 

 are those of Aralia. The genus is very large, most species 

 inhabiting China. The greater number of these have the ventral 

 margin straight, giving a semilunar form to the carpels. The 

 species which most resembles it is A. cordafa, in which the ventral 

 margin is convex as in the fossil. The greater number of speci- 

 mens in the Kew Herbarium have carpels larger than the fossil ; 

 but a specimen (Coll. Dr. Savatier) shows fruits with carpels in 

 almost exact agreement as to size and shape, which indicates 

 that the fossil lies within the limits of variation of the species. 

 A. corclata is an inhabitant of Japan.
