CASUARINACEAE. 
Casuarina stricta, Ait., and C. distyla, Vent. (Plate 
xxxii) The difference between the male flowers of these 2 
exteriores" of Labillardiére (Nov. Holl. pl. spec. ii., 67, t. 
218), and the perianth-segments are his ‘‘valvulae binae 
interiores," from which he named the species C. quadrivalvis 
(=C. stricta). 
It is probable than an examination of the male flowers of 
Casuarina, which has only been attempted in one or two 
instances, would help materially in the satisfactory determina- 
tion of species. It is essentially a task for those who can 
examine living specimens, because the delicacy of the organs 
renders the investigation of dried material very difficult, a 
fact which is noted by Bentham in his great work.
