Number 3 represents a single specimen of unrecognizable char-_ 
acter, but apparently a broad fruit which answers to the following. 
description :— 
Peduncle 1 mm. broad and 8 mm. long, bearing at its upper end a broad, 
four-sided disc 12 mm. at the base, 6 mm. wide at the summit and 8 mm. high. 
without structural markings of any kind except a finely granulated surface 
strongly suggestive of the presence of smal] seeds or akenes. While the observed 
form may haye been derived from crushing, the entire aspect of the specimen, 
together with the granulated surface, strongly suggests a fruit of the type of 
Dorstenia. î
