122 TliE VOYAGE OF H.M.S. CHALLENGER. 



POLYGALE.E. 

 Polygala sp. 



Ki. — Probably an undescribed species, but as there are many Archipelago species, of 

 which we have seen no authentic specimens, we will not venture to give it a name. The 

 genus is generally spread in tropical and most temperate countries, but it is wanting alto- 

 gether in New Zealand, and only one species extends into temperate Australia. 



PORTULACE/E. 

 Portulaca oleracea, Linn. 



Portulaca oleracea, Linn. ; Benth., Fl. Austr., i. p. 169. 



Areou; Timor Laut. Common, especially in maritime districts, in tropical and sub- 

 tropical regions generally, including the most remote islands and islets, being apparently 

 one of the first plants to establish itself on coral islands. 



GUTTIFER^E. 

 Garcinia sp. 



Dammar. — The Guttiferse are strongly represented in Tropical Asia, including the 

 Archipelago ; and the genus Garcinia, which comprises about sixty-five species, is almost 

 confined to this area, a few species only occurring in Africa and Polynesia. Garcinia 

 timorensis (Spanog. in Linnsea, xv. p. 178) we have not seen. There are no published 

 species from Australia, but in the Kew Herbarium there are specimens of one species from 

 Cape York Peninsula. With this exception, and one or two species of Calophyllum, no 

 other members of the order are known to inhabit Australia. 



Ochrocarpus ovalifolius, T. And. 



Ochrocarpus ovalifolius, T. And., MSS. in Herb. Kew. 

 Calysaccion obovale, Miq., Fl. Ind. Bat. Suppl., i. pp. 194 et 500. 



Timor Laut. — Originally described from specimens from Pulu Sangian, an island in 

 the Sunda Straits. Mr Moseley collected it in Observatory Island, one of the Admiralty 

 group. It is the tree alluded to in the Journal of the Linnean Society of London, xv. p. 75, 

 under the name of Calophyllum inophyllum, as growing close to and overhanging the 

 sea, the bases of many of the trunks being almost constantly washed by the waves. The 

 genus comprises about six species, three or four of which are Asiatic, and the others 

 inhabit Madagascar and Africa.
