268 FLORA VITIENSIS. 
very delicate, and the younggst hang down in graceful fringes, clad with needle-shaped leaves of about half 
an inch in length. The slightest breeze—and there is scarcely ever a calm in Fiji—causes the branchlets 
and foliage to tremble (ninini) somewhat like an aspen; hence the natives of Ovalau have given it the 
name of * Leweninini? When coming from Somosomo to Levuka, the crew on board the ‘ Paul Jones’ 
gave me an account of a moving plant, which they assured me grew in the mountains of Ovalau, and which 
excited my curiosity in an eminent degree. No sooner had I landed than two boys were dispatched for 
specimens of the Leweninini; but instead of bringing this Dacrydium, they brought a club-moss, common 
in the tropics (Lycopodium cernuum, Linn.), and which I found was termed Leweninini-sa, on account of a 
certain resemblance to it. Macdonald (Joutn. Geog. Soc. Lond. vol. xxvii. p. 247) fancied this Dacrydium 
identical with the New Zealand Dacrydiwm cupressinum, Sol.; but this is a mistake. He also expressed 
his belief that the wood called Dakua salusalu in Viti is the produce of this tree, and in this he is sup- - 
ported by Mr. Storck, who, being now a permanent resident in Fiji, had ample opportunity to go into the 
question. My inquiries respecting the last-mentioned point have not been attended with success. Nearly 
every native consulted pointed out to me a different tree as the source of that timber. Mr. Pritchard 
also took some pains about it, as the subject was brought before him in his consular capacity. A resident 
in Ovalau had made a contract with a man for a supply of Dakua salusalu. When the timber was delivered, 
eut on Vanua Levu, it was found to be that of the common Dakua (Dammara Vitiensis), quite unlike the 
wood going by the name of Dakua salusalu in Ovalau. Payment being refused, the consul's interference 
was invoked. There being no scientific work to which an appeal could be made, Mr. Pfitchard solved the 
difficulty by deciding that, although the wood tendered might bear or bore the name of Dakua salusalu in 
Vanua Levu, it was not the one recognised by that name in Ovalau; and whereas the contract had been 
entered into in the latter island, only such wood as was called * Dukua salusalu” there need be paid for.

The Roro, a tree thirty feet high in Viti, has been met with only in Viti Levu and Ovalau, and even 
there it is far from common ; and as the pith-like substance of the trunk was reserved for the exclusive use 
of the chiefs, no inducement existed for the common people—as in the Tongan islands—to increase it by 
cultivation,
