•Cladium sp. (PI. VII, fig. 13.) 



Fruit minute, rhomboidal, stipitate; style short ; utricle shining, 

 formed of elongate cells with a central boss ; beneath the utricle, 

 can be seen the outline of a small nut occupying the lower two- 

 thirds of the utricle ; the nut appears to be rounded above and 

 urceolate below. 



Length=l - 7o mm. ; breadth="9 mm. 



The shape of this fruit and the character of its cells agree with 

 Cladium mariscus, but it is much smaller than this species. The 

 apparent size and shape of the nut would agree with minute nuts of 

 Cladium found in the Pliocene of Bidart, near Biarritz. No nuts 

 free from the utricle have been found at Castle Eden. 



A second abortive fruit containing no nut has also been found. 



Caeex glauca Scopoli (?). (PI. VII, fig. 14.) 



Nut broadly oval, triangular in section ; style short ; very 

 coarsely pitted with cpiadrate cells. 



Length = l - 5 mm. ; breadth = l mm. 



The nut almost certainly belongs to Garex glauca, Avith which 

 its characters agree, but is somewhat distorted. 



C. glauca at the present day inhabits Europe, Western America, 

 .and Northern Africa, 



Caeex sp. 2. (PI. VII, fig. 15.) 



Nut ovate, flat, minutely and regularly punctate with cells 

 having a central boss. Two specimens. 

 Length=2 - 1 mm. ; breadth=l"3 mm. 



Caeex sp. 3. (PL VII, fig. 16.) 



Nut plano-convex, elongate oval; style short; very coarsely 

 pitted. 



Length=l"9 to 2'1 mm. ; breadth= - 8 mm. 



Caeex sp. 4. (PL VII, fig. 17.) 



Nut regularly oval, flat or plano-convex ; striate, and rather 

 •coarsely but inconspicuously pitted. 



Length = r3 to 1*4 mm. ; breadth=-75 mm. 



Caeex sp. 5. (PL VII, fig. 18.) 



Nut narrow oval, sharply triangular in section, stipitate ; style 

 lono-, terete ; very coarseby pitted with quadrate cells, the lateral 

 walls of which are grooved on the surface. 



Length (including stalk and style) = 2*25 mm. ; breadth = -7mm. 



Caeex sp. 6. (PL VII, tig. 19.) 



Nut elongate oval, triangular in section, usually much distorted, 

 . as though thin-walled ; style rather short, conical ; very coarsely 

 pitted with cpiadrate cells. 



Length=2 mm. ; breadth=l mm.
