72 FLORA VITIENSIS. 
vol. ii. p. 525. E. Pursetha, DC. l.c. p. 425. Nomina vernac. Vitiensia, * Wa lai” et “Wa 
tagiri."—Common amongst the mangrove vegetation all over Viti (Seemann! n. 139). Also found 
in Malicollo (Forster!), Samoan Islands (U. S. Expl. Exped.), Eastern Australia, and tropical Asia. 
Kitlitz (‘Twenty-four Views of the Vegetation of the Coasts and Islands of the Pacific,’ sub tab. v. 
remarks on the absence of creepers amongst the mangrove vegetation of the Pacific. Entada scandens is the 
only real exception I can call to mind. I have seen festoons of this plant several hundred yards long in 
the mangrove swamps of Viti. Guilandina Bonducella and Derris uliginosa, though sometimes throwing 
their branches over such mangrove trees as happen to grow close to soil just above high-water mark, cannot 
be classed with the real swamp vegetation which often covers the mouth of rivers and low shores. They 
belong rather to the vegetation immediately succeeding the mangroves, composed of such plants as Bar- 
ringtonia speciosa, Calophyllum Inophyllum, Ximenia inermis, Hibiscus tiliaceus, H. tricuspis, Thespesia 
populnea, ete. The flat round seeds of the Walai (Entada scandens, Benth.), called “ai Cibi," or “ai 
Lavo,” have suggested to the Fijians a comparison with our coins, and supplied a word for money (ai 
Lavo), of which their language was formerly destitute, because that article was entirely unknown to them, 
all commercial exchange being carried on by barter. Its stem, when young used in place of ropes for 
fastenings, occasionally attains a foot in diameter, and its pods arrest attention by their gigantic dimen- 
sions, measuring as they do several feet in length. '

1, M. pudica, Linn. Spec. 1501; caule suffruticoso aculeato plus minus petiolis pedunculisque 
piloso-hispidis; foliis subdigitato-pinnatis, pinnis 4—co-jugis ; foliolis linearibus; capitulis ovoideis ; 
legumine oblongo-sinuato 2—5-spermo, valvis articulatis glabris inermibus.—* Sensitive plant” of 
the English and American settlers. In open, exposed places, Lakeba and other islands (Seemann! 
n. 140; U.S. Expl. Exped.). Also collected in the Tongan (Barclay !), Society (U. S. Expl. Exped.), 
and Sandwich Islands. 
l have not been able to obtain any satisfactory evidence of this weed having been introduced, and 
hence have admitted it amongst the indigenous plants. At all events it is now perfectly naturalized, and 
grows in the same kind of places as I have seen it in South America and other countries where it is sup- - 
posed to be truly indigenous. :
