Ficoidece.] SOCIETY ISLANDS. 63 



We have quoted this with a mark of douht, because all the Jossinice are stated to be natives of the Isles of 

 France and Bourbon : at the same time, our specimens so entirely accord with Jacquin's figure, that we 

 consider it almost certain that our plant is the same as his. 



1. Metrosideros villosa ; foliis oppositis ovatis venosis subtus pubescentibus, thyrsis axil- 

 laribus terminalibusve oppositis villosis, floribus sessilibus confertis. Sm. in Linn. Trans. 

 v. 3. p. 268. De Cand. Prodr. v. 3. p. 226. — Melaleuca villosa. Linn. Fil. — M. sestuosa. 

 " Forst. Prodr. n. 215." — M. spectabilis. Gcertn. (fide Menziesii.) — Leptospermum col- 

 linum. Forst. Gen. 36. n. 2. (fide De Cand.) 



In the older leaves, the pubescence altogether disappears, but the calyces and pedicels always continue 

 white with down. 



2. Metrosideros diffusa ; foliis oppositis ovatis venosis utrinque glabris, paniculis axillari- 

 bus terminalibusve oppositis villosis, pedicellis oppositis. Sm. 1. c. v. 3. p. 268. De Cand. 

 Prodr. v. 3. p. 224. 



Our specimens are from Tahiti, as were those gathered by Nelson, and mentioned by Smith in Rees' 

 Cyclopaedia. 



3. Metrosideros obovata; foliis oppositis obovatis coriaceis obtusissimis venosis glabris 

 in petiolum brevem attenuatis, margine paululum reflexo, corymbis axillaribus terminali- 

 busque, calycibus glabris elevato-nigro-punctatis. (Tab. XII.) 



Rami obscure tetragoni, cortice pallide fusco tecti. Folia sesquiunciam ad duas uncias longa, fere sesqui- 

 unciam lata, obovata, obtusissima, coriacea, integerrima, glabra, supra nitida, utrinque parallelim venosa, 

 intra venas reticulata, margine laeviter reflexo, basi in petiolum duas vel tres lineas longum attenuata. 

 Coryinbi multiflori, terminales et axillares. Pedunculi breves, pedicellique glabri. Calyx turbinatus, extus 

 nigro-punctatus punctis elevatis, quinquelobus, lobis obtusis. Petala lobis longiora, dorso punctato scabro. 

 Capsula calyce persistente cincta, 3-valvis, loculicida. 



Hab. Gambier's Island. 

 Tab. XII. Fig. 1, Flower ; Jig. 2, Flower, laid open ; fig. 3, Capsule, with the calyx ; fig. 4, Capsule, with 



part of the calyx removed ; fig. 5, Capsule burst open.

Mr. Collie takes notice of some other species of Cucurbitacea, found in Tahiti, but they do not appear in 

 the Collection : one is mentioned in that gentleman's Notes as the Arroro of the natives, (probably Cucurbita 

 Aurantia,") which is employed for holding the perfumed cocoa-nut oil, or Morwe.
