471. T. elatum, Forst, Prodr. n. 472. Davallia elata, Sw. Syn. Fil. p. 131.—Viti (Seemann ! n. 
761; Milne!). Also from Tahiti (Banks and Solander !). 
Forster's specimen of his Trichomanes elatum in Herb. Mus. Brit. is an almost barren specimen of this 
species, as was determined by Sir W. J. Hooker (Sp. Fil. vol. i. p. 166). The species is very different 
from Davaliia elegans, Sw., with which it has been lately confounded (Hook. Syn. Fil. p. 95). We have 
seen no specimens of D. elegans from Polynesia.

(Greeffe!). Also from Sandwich Islands (Menzies! D. Nelson! Barclay ! Strickland ! Hillebrand !), 
and Aneitum (Milne! M‘Gillivray! C. Moore !). 
This is a widely distributed species, having been found in China by Osbeck, Lind, Staunton, Fortune, 
and others, in Java by Horsefield, in India by Wallieh, in Ceylon by Moon and Thwaites, in Madagascar 
by Thomson and Helsenberg, in Mauritius by Sir J. M‘Gregor, and in Bourbon by Hardwick. It is a 
different plant from Forsters Adiantum clavatum, Prodr. n. 459 (Davallia Forsteri, Carr. ms. in Herb. 
Mus. Brit.), a species from Dusky Bay, New Zealand, which has been overlooked by recent botanists. . 
Var. 8. didyma (Trichomanes didymum, Sol. ms. in Herb. Mus. Brit. and Prim. Fl. Ins. Oc. Pacif. 
(ined.) p. 369. Tahiti (Banks and Solander! Collie! Barclay!). This is a very different-looking 
plant from the normal form, having long narrow segments and smaller indusia; but there are so many 
intermediate specimens that we can consider it as only a marked variety. "
