§§§§§§§ Plilebodiuni, K. Br. Veins forming ample regular arcolce, each with 

 two or more distinct free included veinlets, which bear the sori on their imited 

 points, the costal series of areolce being always destitute of sori. Tab. 48. fig. g.

 a deciduous membranous ferruginous edge ; st. nearly 1 ft. 1., firm, erect, 

 slightly scaly ; fr. 1 ft. 1., G-7 in br., cut down nearly or below quite to the 

 rachis into pinnce i-^ in, br., which are sliglitly crenate towards the bluntish

 with bright ferruginous linear-subulate soft scales ; st. 1-2 ft. 1., stout, erect, 

 naked, glossy ; //•, 8-5 ft. 1., 9-18 in. br., with a long linear-lanceolate terjninal 

 lobe, and cut throughout within j-f in. of the rachis into numerous horizontal 

 entire or slightly undulated lateral pinnce 4-t) in. 1., about 1 in. br,, with a 

 rounded sinus between ; texture sulicoriaceous ; both sides naked, slightly 

 glaucous ; areolce copious, both the fertile and barren ones with free veinlets ; 

 sori irregularly 1-3 serial. — /3, P. areolatum, H. B, K. ; //•. smaller, more_ 

 coriaceous, very glaucous, the lobes closer, the sori uniserial and barren areolae 

 with no free veinlets. — P, sporadocarpum, Willd. — y, P. pnhinatum, Link ; like

 lobe very small. — Hk. Sp. 5, p. IG. 



Hab. Florida and Mexico southward to Brazil, and reported by Dr. Mueller from 

 Australia.— C trilohata, Fde, is a dwarf form with only three lobes. A plant from Spruce 

 (Andes of Ecuador, 5240), agreeing with the small forms of this with uniserial sori in 

 habit and texture, has the sori usually terminal on a free veinlet in the costal areolce, as 

 in typical Gonioplilebmm, hui occasionally a short veiulet is carried from the centre of the 

 one that bears the sorus to the next above it, which springs from the midrib, as in 

 P. f/uatemalense, and as represented in the figure by Mettenius of P. pkurosonim, Kze. ; 

 so that we have then a venation midway between that of Goniophlebium and Phlebodium 

 proper.
