 br., the upper part with nnmerons distant Lomarioid pinntB, sometimes 1 ft.^1., 

 1 Iin. br., below this pinjiatifid, with nnmerons close entire lanceolate-acnminat^ 

 lobes 4^6 in. L, IJ-lJ in. br., which reach down nearly to the rachis, the lower 

 ones passing down gradnallj into a mere nndnlated wing to the rachis, which is 

 continued to its very base ; texture very coiiaceons ; main teins raised, vvith 

 transTeise Yeinlets, and between them copious small areolae with free Teinlets. —

Sori forming large patches on the upper "part of the lower surface of the 

 fertile fronds. A smaU toide^-diffused genus, well marked hy its dichotommis^f 

 forhed fertUe fronds mih Oags'-hom-lUe dirisions. Tab. IX. f . 61 . 



1. P. alcicome, Desv. ; barren fr. rounded, convex, downy when young, the 

 edge sinnaced, the lobes spreading ; fertile fr. 2-3 ft. 1, clustered, erect, 2-3 

 times dichotomous ; vU. dimsions ligulate, blantish, the fruit in the last forks 

 and at their base in very irregular patches ; under surface covered with thin 

 white cottony down. — Hi. Sp. 5. p. 282. 



Hab. Temperate Aostralia, and a larger form in the Mascaren Isles and Seychelles ; 

 aud a similar plant has been gathered by Dr. Sprnce in Peru. 



2. P. e^laopieum, Hk. ; barren fr. rounded, convex, downy when young, the 

 edge more or less lobed, the lobes spreading; fertile fr. 2-3 ft. L, clustered, 

 pepdent, twice dichotomous, the disk and first division broader tlian in the 

 preceding, the patch of fruit surrounding the sintis and passing into the fork so 

 as to be shaped like the letter V ; under surface covered with thin white cottony 

 down. — Uk. Sp. 5. p. 283. O. F. t. 9. A. Stemmaiia, Beauv., oldest name. 



Hab. Gainea Coast and Angola. — ^Dr. Welwitach has famished ns with a plant 

 (P. angolaae, Welw. MS3.) which is moat like this, bnt has a broad-coneate fertile frond 

 9 in. br. at the top, without either forks or homfi^ and with a patch of Iroit nearly as 

 broad as the lamina. 



3. P. grande, J. Sm. ; barren fr. very large,' snborbicnlar, convex, or the 

 upper ones erect, deeply laciniated with spreading or inflexed divisions ; fertile 

 fr. 4^6 ft. 1., pendent, in pairs, the disk broad-cuueate, with the soms against the 

 upper edge, occupying the disk only, with an elongated dichotomously forked 

 division beyond it at each comer ; bolii surfaces green and smooth. — Hi. Sp. 5. 

 p. ^84. IU.Ex.t.BG. 



Hab. IforthAnstralia, Philippines, and Singapore. — lliereisanly one soriferons patch 

 to each frond, and it is sometimes nearly a foot broad. 



4. P. WalUdtU, Hk. ; barren fr. deeply lobed, with inflexed forked divisions ; 

 firtile fr. in pairs, pendent, each in two division^ in each of which the cuneate 

 disk has a rounded upper edge occupied by a soms, from each side of which a 

 once-forked division is prodac«d ; texture thick, the nnder surface matted with 

 yellowish woolly pubescence. — Si. Sp. 5. p. 284. Fil. Ex. t. 97. 



Hab. Malay Peninsula. — Here tbe two soriferons patches are only 3-4 in. br., and 

 occupy a semicircnlar prijection with the forks springing almost from its base. 



5. P. hiforme, Blnme ; barren fr. imbricated, very thick, especially towards 

 the base^ the edge siunato-lobate ; fertile fr. 6-15 ft. L, repeatedly dichotomous
