others in which the fruit-valves are devoid of appendages, unless 

 this should prove a variable characteristic : therefore, the accom- 

 panying flowering specimen may belong to another congener. 

 The remarkable organisation of the anthers for fecundation, 

 recently discovered by Dr. Treub, has subsequently also been 

 discovered in some Amentacea; ; hence on that account the 

 Casuarinete need not be kept far distant from the Amentaceous 

 order. Moreover, as regards foliage, we have in Exocarpos 

 similar extreme diminution of the foliaceous organs along with 

 the development of large leaves in E. latifolia. Furthermore, 

 leaves as minute as in some cupressinous genera occur also in 

 Choretrum, Leplomeria, Tamarix, Calycothrix, Melaleuca, 

 Styphelia and many otlier genera with highly developed floral 

 structure, thougli not connately decurrent.
