15. 3P. confluens (confluent), R. Br. Prod. 146 ; Benth. Fl. Austr. vii. 767. 

 .Frond entire, coriaceous, obtuse or rarely acuminate, contracted into the stipes, 

 covered with stellate hairs or scales usually very small and often deciduous making 

 the fronds appear glabrous, but sometimes almost as abundant as in P. serpens,

 lanceolate varying from 3 or 4in. to nearly 1ft. long. Veins reticulate but con- 

 cealed in the texture as in P. serpens. Sori large, oval or oblong, in a single row 

 on each side of the midrib, often confluent when old. — Bail. Litho. Ferns Ql.

 under surface very minute and the upper surface usually glabrous. Sori in the 

 upper part of the frond distinct, but very small and exceedingly numerous 

 crowded in several rows between the midrib and the margin. — R. Br. Prod. 146 ;

Brown's name was rejected on account of the P. attenuatum, Humb. and Bonpl published bv 

 Willdenow the same year (1810), but that species has been correctly referred by Grisebaoh 

 to the P. nenifohum, Swartz, and the name attenuatum may therefore be retained for Brown's 

 plant. — Benth. 



Also in the South Pacific Islands.
