Can be disting-uished from the common Australian A . Jastnosa R. Br. 

 by its entirely unarmed bi-anches and branchlets. 



Sterculia Edelleldtii F. Muell. Vic. Nat., iii, 47 ; Pap. PI., 

 ii (ix), 55. Yule Island ; Kubunah (Mekeo District). 



The Yule Island specimens are in flower, the Kubunah specimens 

 in fruit, and seem to represent two forms both of which I doubtfully 

 refer to S. Edelfeldtii., which is evidently either a very variable plant or 

 else more than one s^iecies was included by Mueller I.e. under it. 



Family DILLENIACE^. 



Wormia sp. Dilava. My specimens consist of a couple 

 of leaves and a few fallen flowers only, and do not allow me 

 to give a specific name. It is a large tree producing a usefvd 

 timber known at Dilava as " Manava." The leaves are borne 

 on a petiole of about 2h in. (63 cm.), lamina suborbicular about 

 7 in. (17'5 cm.) long and 6i in. (165 em.) broad, strongly 

 veined on the under surface.

 54 ; Bail. Queens. Agric. Journ., xxiv, 20. Port Moresby. A 

 small tree very common on rocky foreshores round the harbour. 



Bixa Orellana Liim. Bail. Queens. Agric. Journ., vii, 348,

Family PASSIFLORACE^. 



Passifiora foetida L. Naturalised almost everywhere near 

 settlements.
