DISTRIBUTION OF PLANTS. 



Diplazia (No. 1). Four to six feet high ; frond tripinnatisect. Frequent in the Interior 

 forest. 



Asplenium nidus; bis (No. 1 Paumotuan) coral-ish>nds and Metia. Frequent everywhere 



in woods, and chiefly epidendric ; frond lanceolate. 

 (No. 2). Creeping; fruct. large, and few, situated towards the extremity of the 



lanceolate frond. In the mountain-forest. 



(No. 3) ; frond niultifid, tripinnatisect. In the mountain-forest. 



? (No. 4). Scandent and highly ornamental; fructification not seen. In shady 



woods. 



(No. 5). Eight inches high; having the habit of A. marinum. 



(No. G). Three feet high; stipe hairy; frond pinnatisect, the segments acumi- 

 nate, jagged. In the mountain-forest. 

 Marchantia (No. 1) ; fructif. peduncled. 



(No. 2) ; fructif. sessile. 



Jungermannia (No. 1). 



Hypnuni (No. 1); delicately plumose. 



? (No. 2) ; twinit)g among branches, like Tillandsia usneoides. On the moun- 

 tain-ridge near Lake Waihiria, and in other localities. 



Gen. Muse, with large capsule, (No. 1). Stem branch. ; capsule a fourth of an inch long. 

 On the niountain-ridge near Lake Waihiria. 



Polytrichum (No. 1) ; very small. On mountain-ridges, growing on the ground. — Mosses 

 in general, were abundant and in much variety. 



Parmelia (No. 2) ; grey. On the bark of trees. 



(No. 3) ; dichotomously divided. 



Usnea (No. 1). A fine species, frequent on branches of trees. 

 Cetraria ? (No. 1). A fine species; large; branch. 

 Sticta (No. 1). 



(No 2j ; a second species; the upper surface white. 



Cenomyce (No. 1); near C. pyxidata. On mountain-ridges, growing on the ground. 



Ramalina (compare No. 1 Paumotuan coral-islands and Metia); very delicate, branching; 

 Growing on branches of trees. Also seen on Aimeo. — Lichens, in general, were abun- 

 dant and various. 



Boletus (compare No. 1 Raraka coral-island) ; hard and almost woody. On trunks of trees. 

 Agaricus (No. 1). — Fungi in general were nowhere conspicuous, nor in much variety; 

 but it should be observed, that very little attention was given by us to the Tribe. 



The preceding List will be found to include less than two hundred 

 indigenous species of Phsenogamous plants and ferns. I was informed 

 by Mr. Morenheit, that the collections made by the enterprising 

 Bertero during his prolonged visit, fell short of five hundred spe- 

 cies :" deducting those that have been introduced, the number of 

 species as yet observed indigenous on Taheiti, can hardly exceed 

 four hundred. As the lofty central mountain remains unvisited, 

 Taheiti may contain as many as eight hundred indigenous species : 

 but to complete the flora, would be a serious undertaking; attended, 

 independent of danger, with great exposure and fatigue.
