extreme branches much compressed, wide; scales very sparse ; fr. solitary, rare. 



Lycopodium (No. 1). Epidendric in the mountain-forest; flowers axillary, or rather on 

 furcate leaf, pedicelled.

 lanceolate ; terminal branching spikes. 



(No. 3). Epidendric; scales long, densely imbricate; fr. axillary, dichotomously 



forked. In the mountain-forest. 



(No. 4); a fourth species. Habit of L. clavatum. Intermingled with Gleichenia, 



on ridges near the coast. 



Cyperus (No. 1), bis Metia. Large; the leaves glaucous beneath. Frequent; also seen 

 on Aimeo. 



Mariscus (paniceus, No. 1, bis Metia). Frequent. 



Bambos, (No. 1). Naturalized, forming extensive beds in the mountain-forest; not seen 



in flower. (Introduced by aboriginal settlers). 

 Panicum (No. 1) ; hairy leaves. Ridges near the coast ; frequent. 

 ; perhaps a second species; smoother. 



Rhapis acicularis, (No. 1). Ridges near the coast; frequent. (Introduced by aboriginal 

 settlers). 



Cenchrus (calyculatus, No. 1, bis Metia). Frequent near the coast. Abundant also and 



troublesome on Aimeo. (Introduced by aboriginal settlers). 

 Paspalum ; compare Metia, (No. 1). Short leaves. 



(No. 2) ; a second species. Leaves broader than in sp. of Metia. 



Digitaria, (compare No. 1 Paumotuan coral-islands and Metia); near D. paspalodes; 



sheaths hairy. Frequent on ridges near the coast. 

 ; possibly a second species. Smoother. 



Saccharuin oflicinarum, (No. 1, bis Metia); the sugar-cane. Cultivated, and also natu- 

 ralized; forming tufts and beds in open situations in the wildest parts of the Interior; 

 the stems, in general, diminutive and juiceless; but intermingled from the same root, 

 an occasional large stem is produced, suitable for transplantation and cultivation. 

 Withered panicles often met with, but there were no seeds. (Introduced by aboriginal 

 settlers). 



Eleusine Indica, (No. 1 ; bis Metia). Everywhere abundantly naturalized ; having been 

 introduced (by aboriginal settlers). 



Marsilca (No. 1). The only aquatic plant; frequent in the pools and slow-moving streams 

 of the cultivated district along the coast; (apparently indigenous, but perhaps intro- 

 duced with taro culture).
