between Atalantia and Paramignya. The shape of the anthers, 

 whether oblong or linear-oblong, can surely not be of very great 

 importance. The torus is in Atalantia Missionis equally raised and 

 stalk-like as in any true Paramignya. The general habit of both 

 genera is exactly the same. A. rnonophylla certainly has a very 

 peculiar calyx, but even this character becomes of less importance 

 when we compare such forms as Sclerostylis, and others.

This is a well-marked species. It has very small flowers, usually 

 4 or 5 stamens, and a very short style. The leaf-like petiole is not 

 seldom larger than the blade itself. 



Great difficulty is experienced amongst the species of Citrus, and 

 Prof. Oliver, from whom we should have expected the best eluci- 

 dation of the same, has left the genus as he found it. The English 

 and native names are for the present the best distinguishing marks 

 and will remain so, as long as botanists fail to define their species 

 properly. The difficulty to recognise the real limits of the species of 

 Citrus, is I believe, due to the fact, that nobody as yet has at- 

 tempted to study the wild growing forms before examining the 

 cultivated ones.
