part 2] PRE GLACIAL FL0BAS FROM CASTLE EDEX. 137 



it to be a species of Cliuoporfitim. The outer coat is missing, but 

 the impression of its cells can be seen faintly on the hard, pitted, 

 inner coat. In form and character of pitting it agrees with 

 C. Nepeta. 



This species, though rare in Britain, is found on the Continent. 

 It ranges into Western Asia and the Himalaya. Its habitat is dry 

 banks. 



Labiate (Staciuoideje), genus (?) sp. 7. (PI. X, fig. 12.) 



Nutlets nearly globular, with a triangular pyramidal base, 

 scarcely angled on the ventral face ; attachment ovate ; outer coat 

 fairly thick, somewhat rough, with well-marked hexagonal pits ; 

 inner coat hard, obscurely striate. 



Length=l"2 mm - ; breadth= - 9 mm. 



Two nutlets : the shape and the attachment of these nutlets 

 indicate that they belong to the sub-order Stachioideae of the order 

 Labiatae. 



Labiate (Stachioideae), genus (?) sp. 8. (PL X, fig. 13.) 



Length = 1 mm. ; breadth =\8 mm. 



A nutlet smaller than the last, but resembling them in shape, 

 with smooth surface formed of delicate thin-walled quadrate cells, 

 also appears to belong to this sub-order of Labiatae. In size and 

 cell-structure it resembles Crauistome versicolor, a plant of the 

 Himalaya ; but the characteristic base is broken, consequently 

 determination is impossible. 



Labiatje (Stachioideae), genus (?) sp. 9. [=Eeuverian, 

 pi. xvi, figs. 25-27 ; also Tegelen 1910, fig. 12.] (PL X, 

 fig. 11.) ' 



Length = 1 mm. ; breadth = 1 mm. 



Two nutlets, one broken, belong to the species figured and 

 described from the Reuverian, and previously figured from Tegelen. 

 They have not been identified, but appear to belong to the sub- 

 order Stachioideae. 



LABIATiE. 



Other nutlets apparently belonging to two or three species of 

 Labiatae are too badly preserved for description or photography. 



SOLANACE^L 



Solanum nigrum Linnaeus. (PL X, fig. 15.) 



A fragment of the margin of a discoidal seed shows the deep 

 cup-shaped cells with crenulate margins characteristic of so many 

 Solanaceae. In size, curvature, and the character of the cells it 

 agrees perfectly with the seeds of Solatium nigrum, to which 

 species it probably belongs. S. nigrum is an inhabitant of the Old 

 World.
