972 Thoday and Ber ridge. — The Anatomy and Morphology of 
E. nebrodensis , cases were met with in which two otherwise independent 
synangia were fused by their adjacent ends. One of the most irregular 
species is E. aspera , in which occurred all the forms indicated in Text-

of E. aspera , showing the great variation in this 
species. 
Text-fig. xvii. Two anthero-

Text-fig. XV indicate the main lines along which reduction has taken place. 
II. Vascular. The three bundles which enter 1 the axis of the male 
flower fuse more or less completely into a single crescentic bundle (Text-fig.

below the level of insertion of the two leaf-like appendages. The crescentic 
mass thus formed almost immediately separates again into two large bundles, 
and between these a minute third one is commonly found on the abaxial
