of the Recent Flora of Britain . 191 
Thymus serpyllum, Linn. 
A detached calyx. Postglacial (Clyde beds), Roxburgh 
Street, Greenock. Mr. Thomas Scott has sent a calyx of 
Thymus , which, though it does not exactly match any of the 
recent specimens with which Mr. Ridley and I were able to 
compare it, yet seems undoubtedly to belong to this species. 
The calyx in the recent plant is very variable, and our fossil 
comes within the extreme limits. 
[Scutellaria galericulata, Linn.] 
Interglacial, Cowden Glen. Mr. Mahony records a leaf 
closely resembling this species 1 . The leaf of Scutellaria being 
non-deciduous and of a soft texture, it is scarcely likely to be 
found fossil, and in the absence of the very characteristic fruit 
the species ought not to be included in the list. 
Prunella vulgaris, Linn. 
Two nutlets, only one well-preserved. Interglacial, Red- 
hall. Somewhat smaller than my recent specimens, but other- 
wise indistinguishable. 
Stachys palustris, Linn. 
Several nutlets. Interglacial, Redhall. Preglacial (Cromer 
Forest-bed), Beeston. 
Galeopsis tetrahit, Linn. 
Three nutlets. Interglacial, Redhall. This species is com- 
monly considered to be an introduced weed of cultivation, but 
it was certainly native during this interglacial period. The 
specimens agree in every respect with the recent forms, but G. 
Tetrahit and G. speciosa cannot be distinguished by the fruit. 
Atriplex patula, Linn. 
Numerous seeds. Postglacial (Clyde beds), Garvel Park, 
and Roxburgh Street, Greenock (Mr. Scott). Interglacial, 
Redhall. Preglacial (Cromer Poorest- bed), Sidestrand and 
Pakefield. In the interglacial and preglacial beds only the 
smaller seeds of this species have been found.
