296 THE VOYAGE OF H.M.S. CHALLENGER. 



SEEDS AND SEED-VESSELS FROM THE SEA-BEACH OF 

 THE ARROU ISLANDS. 



DIPTEROCARPE^E. 



Vateria papuana, Dyer, ante, p. 123. 

 Sea-beach, Arrou. 



It is uncertain whether this grows in these islands or was accidentally washed ashore ; 

 but Beccari (Nuovo Giornale Botanico Italiano, v. 1873, p. 330), in a sketcb of the Flora, 

 says it is singular that the Dipterocarpese are absent. See also p. 287. 



STERCULIACE^E. 

 Heritiera littoralis, Dryander. 

 Sea-beach, Arrou. 

 This was also found in the New Guiuea drift. See p. 288. 



MELIACE^E. 



Flindersia amboinensis, Poir. ? (Plate LXIV., C.) 



Flindersia amboinensis, Poir. in Lam. Encycl. Method. Suppl., iv. p. 650 ? 



Sea-beach, Arrou. 



The genus Flindersia comprises about six Australian species, and one has recently 

 been discovered in New Guinea. Possibly the capsule represented in our plate belongs 

 to a species distinct from the Amboina one, which is figured by Rumphius (Herb. Amb., 

 iii., p. 201, t. 129). His figure of the seed-vessel, which is reduced, represents it tapering 

 much more at both ends than ours is. Flindersia oxleyana, from the Brisbane River, in 

 Queensland, is also very near the present, which, though picked up on the beach, was 

 probably not stranded there, but grew in the island. The capsule is not water-worn, and 

 the fragile seeds are in a eood condition. 



This ought to have been included in the preceding list of the plants of the South- 

 eastern Moluccas ; but it was overlooked, as there was no Herbarium specimen. 



APOCYNACIL®. 



Cerbera odollam, Ga3rtu. 

 Sea-beach, Arrou. 

 The distribution and other particulars of this plant will be found at pp. 164 and 293.
