part 2] PBEGLACIAX FLORAS FROM CASTLE EDEX. 123 



should be regarded as a distinct species, as a variety, or be included 

 in the species. 



The specimen described from Tegelen {op. jam cit. 1907, tig. 5) 

 is the same as the Castle-Eden form of the species. 



E,A.jN T USrCU,LUS edexensis, sp. nov. (PI. Ylll, fig. 1G.) 



Aehsenium perparvum, ambitu obovatum, inflatum, pericarpio 

 itenui crasse foveato. 



Achenes obovate, inflated, thin-walled; attachment basi- ventral ; 

 style subapical; outer coat thin, coarsely thimble-pitted, and finely 

 striate longitudinally ; inner coat transversely striate. 



Length = '8 mm.; breadth= - 75 mm. 



This minute achene of Ranunculus is very common. The walls 

 are very thin, and in consequence it is always distorted. I have 

 been unable to find any Ranunculus at all like it. The achene is 

 very thin-walled for that genus, and I considered whether it 

 might be some species of Urticacea? ; but again 1 can find nothing 

 :at all like it, and, as the character of the walls and of the attach- 

 ment are in keeping with Baiiunculus, I have placed it under that 

 genus. 



CRUCIFEK.E. 



Alliaria sp. (PI. VII I. fig. 17.) 



Seed ovoid, hilum basal ; testa finely striate longitudinally, 

 formed of quadrate pits with thickened lateral walls : it is folded 

 into conspicuous longitudinal ribs which anastomose, and coalesce 

 along the line of fission of the seed on one side ; germination by 

 fission through the base and apex into symmetrical halves. 



Length = 1*7 mm. ; breadth = 1 mm. 



Characters in every way similar to these are seen in A. officinalis; 

 but the seed is usually much larger than the fossil, the quadrate pits 

 .are not thickened laterally, and do not therefore cause longitudinal 

 striations, and the folded ribs are closer and less regular. A 

 fruiting specimen, from an altitude of 8000 feet in Kashmir, has 

 smaller seeds, some of which are nearly as small as the fossil, but 

 broader and more oblong (PI. VIII, fig. 18) : they do not show 

 the fine striations. I have been unable to compare the fossil with 

 seeds of the Japanese species A. brachycarpa and A. wasabi, and 

 have therefore not described it as a new species. 



SAXIPEAGACE^E. 



Chrysosplenium sp. (PI. VIII, figs. 19 a & 19 b.) 



Seed minute, ovoid, raphe forming an external lateral ridge from 

 base to apex ; hilum basal, thin-walled ; surface glistening, with 

 sparse minute spines arranged in longitudinal rows. 



Length="75 mm. ; breadth = "5 mm.
