I possess a specimen of this plant, gathered by Forster in 
N. Zealand, during Captain Cook’s voyage, and in all proba- 
bility it is the same plant named “ Trichomanes” in Jacq. 
Herb. and not the L. pellucida to which Presl refers it, com- 
municated, by Sir Joseph Banks, to the Austrian Botanist: 
to Forster therefore is due its discovery. It seems to have 
remained unknown to any other Botanist till the Rev. Mr. 
Colenso detected it in 1838 and 1841 in the above local- 
ities. Its affinities are with the N. Zealand Todea pellucida, 
(see Tab. 8. of Icones Plantarum), and the Australian Todea 
Fraseri, Hook. et Grev. Ic. Fil. t. 101. The three we think 
are well separated from Todea, and Presl has determined the 
er of his Genus Leptopteris in his Suppl. Tent. Pteridogr. 
». 70. As aspecies, it is abundantly distinguished by the out- 
e of the frond tapering at the base, the stout stipes and main 
rachis, and the copious bristly tomentum of the underside of the 
main and partial rachis. ‘Some of the fronds,” Mr. Colenso 
says, “are upwards of four feet in length. The old fronds 
spread outwards, while the younger ones, generally three in 
number, circinnate and of a lighter green, rise in the most 
graceful suberect manner from the centre.”
