e has been some controversy as to sex distribution in the 
cai of P. quadriloculare, and in view of this it is not without 
interest to find R. Brown noting of the species ar described, 
‘¢ Masculi flores in diverso frutice.”’ We are unable, we may add, 
to confirm the truth of Baillon’s assertion re reant via p. 853) 
_ the flowers of the first-named are sometimes ones all

The MS. name (Xylococeus -seriores) given nae Brown to P. quadri- 
loculare has hitherto been misprinted. Ben am (Fl. Austral. vi.
