germination fissure, or perhaps part of the valve, is continued 

 along the margin of the seed through and beyond the apex ; surface • 

 of thick-walled hexagonal cells. 



Length := 1*3 mm. ; breadth=/8 mm. 



Two specimens. The curious structure of these specimens seems- 

 best explained as that of arillate seeds. I can suggest no position, 

 for them. 



Caepolithes sp. 9. (PL X, fig. 26.) 



Carpel minute, hard, rhomboidal, somewhat winged, beaked,, 

 spurred behind, ridged dorsally and ventrally ; stipitate, attachment- 

 ventral ; micropyle apical, gaping ; apparently two-seeded. 



Length=3 mm. ; breadth = "8 mm. ; depth (exclusive of stalk) 

 = "5 mm. 



If this carpel had been larger, I should have thought that it 

 might be that of Liriorfendroii ; but it is so small that I cannot 

 think that any species could have so minute a carpel, though the 

 seeds, and portion of a very small fruiting catkin, were recorded 

 from Reuver. The length of the Reuverian carpel, which had no 

 wing, was 4 - 5 mm., whereas the Castle-Eden carpel (including the 

 long beak) measures only 3 mm. 



I modelled the carpel to a large scale, in order the better to see 

 what kind of fruit it suggested. The curious facetting of the 

 upper and lower surfaces seems to indicate that it formed part of a 

 loose catkin, and that the stalk was sunk in some kind of elongate 

 rhachis. 



Caepolithes sp. 10. (PL X, fig. 27.) 



Achene arcuate, flat ; attachment basal, triangular ; stjde apical.. 

 Length = 3 mm. ; breadth = 1 mm. 



This appears to have been one of a number of achenes closely 

 adpressed in a whorl. I can suggest no position for it. 



Caepolithes sp. 11. (PL X, fig. 28 ; also figs. 29 a & 29 b ?) 



Cupule or placenta truncate-obconical, with a cap-shaped hollow 

 above, and the base deeply hollowed below like another inverted 

 cup ; Avails somewhat loose-textured, of large quadrate cells ; surface 

 light brown, showing the remains of an outer thin, close-textured, 

 black coat, finely striate longitudinally : there are also the remains 

 of what appears to be another light-brown crumpled coat external 

 to these, formed of smooth shining hexagonal cells ; but whether 

 this is proper to the cup, or only adherent, I am not certain. The 

 base (the 'inverted cup') shows a well-defined rounded break or 

 ' lip ' in its side, by which evidently the peduncle entered, being 

 partly clasped by the cup ;, it also shows a central boss of fibres at 

 the actual point of attachment. There is no indication of these 

 fibres emerging in the cupule, unless it be at the margin. 



Diameter=3'4 mm. ; depth:=2-4 mm. 



The nut belonging to this cupule or placenta probably showed
