and raphe, and its glistening surface are in keeping with the seed& 

 of Ghrysospleniwm oppositifolium; but it is larger, and the seeds- 

 of that species are covered with glands arranged in longitudinal 

 rows, instead of spines. Hardly any of the numerous species o£ 

 Ghrysospleniwm are represented by fruiting specimens in the Kew 

 Herbarium : but an examination of such material as I could find 

 showed that the fossil falls within the degree of variation of the- 

 size of the genus ; that the shape of the seed, the character of the 

 hilum and raphe, and the glistening surface, are generic characters ;-. 

 and that some species are hairy or spiny. Thus, a drawing of the 

 microscopic seed of G. henryi shows minute hair-like glands, and 

 G echium has thin, winged, longitudinal ribs crested with spines. 



The specimen does not belong to any of the European species ; 

 but, in view of the large number of species chiefly inhabiting China,. 

 Japan, and North America, which I have been unable to examine,. 

 I think it unwise to describe it as a new species.

LlQUIDAMBAR Sp. (PL VIIX, fig. 20.) 



A fragment of a compound fruit showing receptacular hollows- 

 agrees in its structure with the receptacle of Liquiclambar. It is- 

 too fragmentary to describe, but I do not doubt that it belongs to 

 the genus. 



L. orientalis was recorded from the Reuverian. There are four 

 species in the genus : one a native of Asia Minor ; one of China 

 and Formosa ; one of Atlantic North America and Central 

 America ; and the other of Central America.

Spikjea Ulmaeia Linnaeus. (PL VIII, fig. 21.) 



Follicle crescentic, fiat; stjde apical; attachment ventral; 

 surface rough, coarseby striate dorsally, and pitted. 

 Length=2 - 3 mm. ; breadth =1 '2 mm. 



The follicle is in exact agreement with those of Spiraea Ulmaria. 

 Present distribution : Europe and Northern Asia. 



Spiraea, erectistyla, sp. nov. (PL VIII, fig. 22.) 



Folliculus parvus, oblongus, sectione transversa triangularis, 

 margine ventrali rectus ; stylus ad latus ventrale apicalis erectus. 



Follicle small, oblong, triangular in section, facetted at the 

 straight ventral margin ; inner faces smooth ; dorsal somewhat 

 rough ; style erect, apical, at the ventral margin ; attachment 

 basi-ventral ; dehiscing by a median suture along the ventral 

 angle through the style and upper part of the dorsal face. Two 

 specimens. 



Length=2 mm. ; breadth=l"2 mm.
