Pitcairn Island. (About 130° W. long., and 25° S. lat.) 



This island was visited by Captain Beechey, and there are specimens of a few plants in 

 the Kew Herbarium collected there by Cuming and others; among them Hibiscus tiliaceus, 

 Osteomeles anihyllidifolia? Metrosideros jiohjmorjjha, Morinda citrifoUa, Guettarda 



1 Memoirs of the National [American] Academy of Sciences, ii. 1884, p. 88. This island must not be 

 confounded with the Caroline Archipelago in North-western Polynesia, concerning the botany of which almost 

 nothing is known, though it has been visited by one Russian, and at least one French exploring expedition. 

 Endlicher enumerates only the following seven plants — Paspalum reimarioides, Brongn, ; Eleusine indica, Gaertn. ; 

 Lepturus repens, R. Br.; Saccharum insulare, Brongn.; Centotheca lappacea, Desv. ; Ischeemum intermedium, 

 Brongn.; Gycas circinalis, Linn. — three of which are described as endemic. Kittlitz gives four views of the 

 ve^ctatiiin of Calan, and two of Lugunor, islands of this archipelago. The plants represented include the 

 common Polynesian species of such genera as Thespesia, Pandanus, Qordyline, Cocos, Scmvola, Toumefortia, 

 Hibiscus, Calophyllum, Barringtonia, Artoearpus, Guettarda, and Tacca; and one of the larger trees is said to 

 be a species of Myristica. 



- Osteomelesis an outlying genus of Rosacese Ponieas, of which there are about eightor ten species, inhabiting 

 the Andes, and Osteomeles anthyllidifolia, which is restricted to Polynesia. This was first collected in the Sandwich 

 Island- by Menzies, and the genus Mas founded upon it (Lindley in Trait*. Linn. Soc. Lond., xiii. p. 98, t. 8).
