2/0 POLYPODIUM, § PHEGOPTERIS. 



hairy on the costules and veins especially beneath (where 

 they are often hispid) broad-oblong ovate or deltoid-ovate 

 acuminate tripinnate sometimes viscid beneath opaque, pri- 

 mary lower pinnse sometimes nearly a foot long and bipin- 

 nate, all the pinnae sessile, ultimate ones or pinnules quite 

 adnate H-2 inches and more long ^-h an inch wide oblong 

 bluntly acuminate deeply almost to the costa pinnatifid, 

 segments semiovate suberecto-patent subacute, the inferior 

 basal one shorter than the superior and always adnate 

 with and decurrent upon the rachis, the margin entire or 

 dentato-pinnatifid, veinlets simple distant, sori more or less 

 copious one to each tooth or segment dorsal, secondary ra- 

 chises often villous. 



Ilab. Jiian Fernandez, on wooded hills, Bertero, n. 1660, Cuming, n. 1326, 

 Douglas, Scolder, Philippi (" Phegopt. rugulosa "), very large form. Concep- 

 tion, Cuming, n. 823. Valdivia, Bridges. Chiloe, Capt. Ph. King. Chatham 

 Island, Galapagos, Capt. Wood (submembranaceous, segments elongated, lobes 

 shorter, lowest inferior often forming an axillary lobe between two segments, pro- 

 bably distinct). — Var. j3. Valdivia, Philippi. It is remarkable that so distinct a 

 looking species as this, and collected by so many Chiliati travellers, should, as 

 far as I can find, be hitherto unpublished. 



220. P. (Phegopteris) aquilinum, Th. ; caudex ?, stipes 1-2 

 feet long stout dusky-brown clothed at the base with linear- 

 acuminated imbricated glossy scales ^-| of an inch long, the 

 rest tuberculate and downy and appresso-paleaceous with 

 small scales, fronds 1-4 feet long sometimes 1-1^ foot broad 

 hard thick coriaceous and dark-brown when dry broad del- 

 toid-ovate bi-tripinnate, primary inferior pinnae often oppo- 

 site 6-10 itiches long obliquely ovate, their inferior secondary 

 pinnae the longest, ultimate pinnae or pinnules H-3 inches 

 long oblong linear sessile rather obtuse deeply pinnatifid 

 almost to the rachis, segments ovate subfalcate entire, lowest 

 inferior one especially adnate with and often wholly attached 

 to the rachis thus forming an intermediate lobe, veinlets sunk 

 very indistinct apparently simple, sori forming two series be- 

 tween the costule and the margin, main and secondary rachises 

 very stout straight pubescent partially and minutely scaly and 

 tubercled, costules beneath very pubescent. — Thouars, Fl.
