ated by a conspicuous channel ; radiating ribs strong on the keels, interrupted over the 

 dorsal channel, soon disappearing over the smooth much sunk lateral area. 



Length 6.5 mm., breadth 5.0 mm. Tegelen. 



A single carpel, found at Tegelen by Dr. Tesch in 1912, is all that we have seen 

 of this species. The carpel somewhat resembles that of A. pallida (fig. 17) of South 

 Europe; but it is considerably larger, more oblique, and of harder texture. We can find 

 no other living species with which it is comparable. Nothing was before known of the 

 genus Althaea in the fossil state. 



STERCULIACEAE? 



PI. XII, figs. 18, 19. 



Seed oblong cuneate, tubercled dorsally, facetted ventrally; hilum ventral large, 

 with radiating striae ; raphe and chalaza ventral. 



Length 5.5 mm., breadth 3.0 mm. Swalmen. 



Two specimens having a resemblance to the seeds of Sterculiaceae section Buett* 

 nerieae. We have been unable to identify them with any living genus ; but can make 

 no other suggestion as to their affinities. 



DILLENIACEAE. 



ACTINIDIA FAVEOLATA Sp. nov. 



PI. XIII, figs. 1-4. 



Semina ovalia, tumid a, later aliter parum compressa, obtuse carinata; 

 tegmen foveolis regularibus sexangulis ad hilum minoribus et magis elongatis 



TECTUM. 



Seed oval tumid, somewhat compressed laterally, bluntly keeled ; hilum slightly 

 produced and expanded; micropyle close to hilum; tegmen opaque crustaceous shining, 

 covered with small deep regular hexagonal pits which become smaller and more elongate 

 at the hilum ; interior with low hexagonal bosses corresponding with the ends of the pits. 



Length 3.5 mm., breadth 2.25 mm. Brunssum, Swalmen, Reuver, Tegelen. 



The seeds of the living species of Actinidia (figs. 5, 6) vary but slightly in size 

 and shape. Our fossils differ from all that we have been able to examine, and fruits of 

 nearly all the species are in the Kew Herbarium, but they approach more closely to the 

 Chinese forms than to those of the tropics. From all the living forms they differ in 

 the fineness, closeness, and the extreme regularity of the hexagonal pitting, which 

 makes the fragments resemble pieces of honeycomb, whence the specific name. 



The actinidias are usually rambling bushes growing like our blackberries, though 

 one is a small tree. They are common in China and Japan, and occur also in India, but 

 are now extinct in Europe. 



Imperfect specimens of these seeds were discovered by us in 1905 at Tegelen
