A small genus of large and handsome species, conspicuous for their tree-like growth, of which the 
following have not yet been found in Viti, viz. :—l. H. rigidum, (sp. nov.), Mitt.; ramus erectus, inferne 
simplex, fois appressis tenuiter acuminatis obtectus, demum denudatus, rigidus, superne in frondem sub- 
oblongam ramis simplicibus ramulosisve pluribus pinnatus; folia in frondis medio late subovata lanceolata 
acuta, substriata, nervo pereurrente dorso dentato, margine serrulata, cellulis angustissimis densis firmis 
areolata.— Aneitum (Milne!).—Fronds with the stipes four inches high. Foliage dull brownish-green.

in the beds of gullies (100-2000 feet) (Powell! n. 107). 3. H. Miinei (sp. nov.), Mitt.; stipes bi-triun- 
cialis, ruber, rigidus, erectus, apice in comam frondiformem subdeltoideam subhorizontalem divisum ; folia 
in stipite laxe imbricata, patentia, late ovata, acuminata, nervo excurrente, margine serrata, cellulis elongatis 
ad margines folii minoribus brevioribus, basalibus ad angulos majoribus fuscidulis, folia in ramis ovato-lanceo- 
lata nervo excurrente dorso dentato marginibus dentibus duplicatis serratis.— Aneitum (Milne!)—WNear 
to H. divaricatum, but differing in the stipes not being covered with rootlets, the leaves of the branches 
shorter, more dense and rigid. In the same respects this species differs from the HZ. comosum, H. Steberi, 
and H. comatum of Australia, Tasmania, and New Zealand, 4. H. divaricatum, Hornsch. et Reinw. Nova 
Acta Acad. Cms. Leop. 14. vol. ii. Suppl. t. 40.—Isle of Pines (Milne!).
