most easterly known point, but have been collected in Malaya. Of all 
the extensive botanical evidence against the naturalness of Wallace’s line 
between Malaya and New Guinea, this is the most conclusive. 
As a matter of fact, the fern flora of all Polynesia is Malayan in 
general character, as evidenced by the fact that King’s collection contains 
eighty-seven species found both east and west of New Guinea. There 
are also sixteen species previously known in New Guinea only, and forty- 
two species described here as new.

Distinguished from its apparently nearest relative, M. melanesica Kuhn, by 
much finer serration, veins standing at nearly a right angle, and the fine scaliness, 
characters easily recognized even on small fragments. 
2. Marattia grandifolia Copel. species nova. 
Rhachi pinnae glabra, angustissime alata; pinnulis breviter (ca. 2 mm) 
stipitatis stipite subvelutino glabrescente, maximis ultra 20 cm longis, 
ultra 3 cm latis, basi inaequale cuneato-rotundata, aeuminatis, acute 
leviter serratis, herbaceo-coriaceis, glabris, infra pallidis; venis simpli- 
cibus haud pellueidis ; soris submarginalibus, ca. 2 mm longis, sporangiis 
utroque latere 9-12, indusio inconspicuo, scarioso, receptaculo oblongo- 
lineare. Species M. macrophyllae De Yr. affinis, qua pinnulis majoribus 
durioribus, venulis opacis distinguenda. 
No. 305. 
Of the numerous forms sometimes grouped under M. fraxinea, this is near 
only to the M. macrophylla named above. The leaflets of M. grandifolia are 
broadest below the middle.
