Ceriops pauciflora, Bentb. 



Ceriops paucijtora, Benth. in Hook. Loud. Joum. Bot., ii. 18-13, p. 218. 



Admiralty Islands. — Also found in New Ireland. It is, perhaps, not specifically 

 different from Ceriops candolleana, Arn., which is widely diffused on the sea-coasts of the 

 Old World, including North-eastern Australia and Eastern Africa. Ceriops is a small 

 genus restricted to the Old World. 



MYRTACEyE. 

 Eugenia malaccensis, Linn. 



Eugenia malaccensis, Linn.; Seem., El. Vit., p. 77; Nadeaud, Enura. PI. Tahiti, p. 79; Jouan in 

 M&n. Soc. Sci. Nat. Cherbourg, xi., 1865, p. 108 (Jambosa); Mann in Proc. Amer. Acad., vii. 

 p. 166. 



Admiralty Islands. — Generally diffused in Tropical Asia and Polynesia, but probably 

 introduced in the eastern islands of Polynesia. Jouan states that it is very little spread 

 in the Marquesas, only a few trees existing here and there ; and Mann treats it as an 

 introduced tree in the Sandwich Islands. 



Barringtonia speciosa, Linn.

Barringtonia butunica, Forst., Char. Gen. PL, t. 38. 



Admiralty Islands. — Generally spread in Polynesia, except the Sandwich Islands. 



Barringtonia racemosa, Blume ? 



Barringtonia racemosa, Blume? Seem., El. Vit., p. 83. 



Admiralty Islands. — The true Barringtonia racemosa reaches the Fijis and Samoa. 



MELASTOMACE^E. 



Melastoma malabathricum, Linn. 



Melastoma raalabathricwm, Linn. ; Hook, f., Fl. Brit. Ind., ii. p. 523; Benth., Fl. Austr., iii. p. 292; 



Miq., Fl. Ind. Bat., i. 1, p. 507. 

 Melastoma put g a nth am, Blume; Miq., FL Ind. Bat., i. 1, p. 507 ; Hook, f., Fl. Brit. Ind., ii. p. 523. 

 Melastoma denticulatum, LabilL, Sert. Austr. Caled., i. p. 65, t. 64 ; Seem., FL Vit., p. 90. 

 Melastoma velutina, Seem., Fl. Vit., p. 90, in nota. 



Admiralty Islands. — As circumscribed by Bentham, this species is very widely spread 

 fn Tropical Asia, and extends to Eastern Australia southward to New South Wales. It is 

 also found in the Seychelles, and in Polynesia it reaches New Caledonia, the Fijis, and 

 Samoa. It is very variable. The genus Melastouui is restricted to about the same area 

 as the present species.
