officinalis, wliicli attain a height of nearly 30 ft., with dark green 

 foliage and densely intertwining branches stretching downwards. On 

 the eastern side of the lagoon, arc many trees of Jilii-:op]iora mucronota, 

 growing nearly 6 ft. high, with bright green leaves, sending their 

 branches upwards and their roots down from the middle of the 

 stem. On this side of the lagoon, may be found some Najas, Zostera, 

 JRuppia and Zannicliellia. 



On the sandy shore, the most common plants which form the 

 littoral vegetation in the island are as follows :- 



Hibiscus tiliacciis L. Toiirncfortia argeiitia Lam. 



Heritie7-a littoralis Ait. T. sarnieiitosa Lam. 



Canavalia ohtiisifolia DC. Ipomaea biloba FoESK.

Tephrosia purpurea Pees. Alycporuni bontioides A. GrAY.

Sophora tomentosa L. Euphorbia Atato FORST. 



Caesalpinia Botiducella Bl.. Excoecaria Agallocha LiInN.

Pemphis acidula FoEST. Freycinetia forinosana Hemsl. 



Tetragoiiia expansa Mitee. Pycreus polystachyus EeaI'V.

Wedelia bijlora DC. Dactyloctiuiuin. aegvptiacuin WiLLB. 



Scaevola Kocnigii Vahl. Zoysia pungens WlI.T.P. 



Jpomaea hilohci is one of the most plentiful of flowers among the 

 vegetation on the shore. The i)lant seems to thrive on ground 

 composed of sand and nmd. In such places, we see many trees of 

 Scaevola Koeniyii, with climbing Ahrus precatorius and Tephrosia 

 purpurea. Pandanus odoro.tis^imus is another plant which is commonly 

 met with in the littoral vegetation. The plant thrives very well on 

 the sea-shore, especially on sandy ground. Besides this species, there 

 is another plant belonging to the same order, nan;ely, Freycinetia 

 formosana, which is rather small and of creeping habits. The plant 

 is limited to the noiihern part of the island, where it is very abundant. 



In Takaw, especially on the hills of the coral formation on the 

 sea-side coast of the lagoon, there is found a very peculiar growth of 

 Eupliorhia TirucaUi with greenish, terete, aphyllous brandies forming 

 very dense bushes. The plant is generally 10 ft. high, but sometimes 

 it attains a height of more than 20 ft. It is thought to have been 

 introduced from Africa. Curious to say, the plant is limited in 

 Formosa to the environment of Takaw. 



It has been observed bv Dr. A. He^'ry that the littoral flora of
