{B, heteroj)hyIia, Colla, and B, scabra, Lodd., inserted in Steud. Nom. Bot. cd. 2, as 

 Australian plants, are unknown to me, nor can I find any description of them. They are 

 probably garden names given to some of the species here enumerated.) 



Series I. Cycloptkr^. — Leaves entire, toothed, or rarely lobed. Wings 

 of the capsule extending from the base to the style, or nearly so ; each 

 carpel, including its wing, nearly orbicular, or longer than broad. Dissepi- 

 ments persistent on the axis. 



In the following 12 species, great as is the diversity in the size of the capsule and the 

 precise shape of the wings, these differences afford no specific characters, and are often very 

 dithcult io class as varieties, even when perfectly ripe and well-formed capsules are obtained ; 

 and the shape of the wing often alters much during growth, or is apparently affected by 

 the manner in which i\iQ capsule has ripened. The very shining seeds distinguish 2 specits, 

 but where they are usually opaque they sometimes are 'somewhat shining. There remains 

 little but the very uncertain character sderived from foliage to separate all these species, which 

 are yet much too constantly dissimilar to be united into one.
