scarcely exceeding an incli in length and 1-2 lines in breadth 

 linear obtuse, in both the margin are incurved so as to render 

 the back convex, venation sunk and wholly concealed, sori 

 few large near the margin orbicular or oval confluent con- 

 fined to the upper half or extending the whole lengtli much 

 sunk yet prominent. — Bj\ Prodi' . Fl. Nov. Holl. p. 14G.

 and New England, il/Mc//??-.— The Pohjpod'mm conflams of Brown's ' Prodroinus,' 

 placed by him next to his P. rupcstre, has never, that I know of, been noticed 

 by any other author, although the vicinity of Port Jackson is the acknowledged 

 locality. I have, however, in my herl)arium, good specimens of a species ga- 

 thered by Allan Cunningham, which he lias confidently marked " P. confluem, Br., 

 from rocks and decayed timber in woods, Brisbane river." Identically the same 

 has been sent me by the excellent Mueller, from localities in North Australia. 

 If it be the true plant, it has dimorphous fronds, and is the smallest and prettiest 

 of the group; and it is further remarkable for the copious, silvery, appressed, 

 farinaceous scales, abundantly mixed with the stellated hairs. I have been some- 

 times disposed to think P. carnosus, Bl. Ic. Fil. t. 19 (which I have doubtfully 

 referred to a state of P. adnascens) may be a more luxuriant state of this. 



305. P. (Niphobolus) ac?wfl5ce/w, Sw. ; caudex creeping pa- 

 leaceous with lanceolato-setaceous scales, stipites distant 1-2 

 inches long, fronds dimorphous carnoso-coriaceous dark-green 

 above but hoary with sparse stellated pubescence beneath 

 and paler and even white with more copious compact hairs ; 

 sterile fronds 2-4 inches long spathulate or elliptical-lanceo- 

 late obtuse; fertile ones 6-8 inches long linear or oblong 

 obtuse or acute both kinds tapering below into the stipes, 

 costa subcarinate, costules sunk obscure their areoles including 

 free-veinlets, sori deep sunk in the tomentum and in the sub- 

 stance of the frond on each side the costa arranged 5-G in 

 obliquely transverse series, capsules long-stalked mixed with 

 long-stalked stellated scales. — Sw. Syn. Fil. p. 25 and 228.
