ascending almost filiform ])ranched incrassated and scaly at 

 the extremity bi-triceps, stipites stramineous slender filiform 

 sparse a span long destitute of scales downy, fronds ovato- 

 deltoid 4-5 inches long thin membranaceous pellucid and 

 minutely pellucidly dotted pinnate, pinnae rather distant 7-9, 

 lateral ones 2 inches long opposite subfalcate obtusely acu- 

 minate quite entire minutely villous decurrent at the inferior 

 base (except the lowest pair), superior base with a sharp 

 auricle appressed to the rachis, in the upper pair adnate with 

 the rachis and confluent with the base of the long terminal 

 pinna which is nearly 3 inches long, veins lax remote simple or 

 forked near the base not unfrequently anastomosing so as to 

 form a distinct areole near the base of the line of fructifica- 

 tion, the very base parallel with the rachis free from veinlets, 

 sori forming two slender lines close by the costa, the inferior 

 one diverging from the costa at the base, involucres hairy 

 like the frond. (Tab. CLVIII.) 



Hab. Tovar, Veneauela, Fendler, 1854-5 {Plantar r<?»(?^7«e/fe),w. 116.— Whether 

 this be really a good species or not I am unable to say. It exhibits peculiarities 

 which prevent me from referring it to any other known to me, but which are better 

 understood by a reference to the figure than by any verbal description. The 

 specimen is a'solitary one with the two fronds here represented ; the caudex or 

 rhizome, and the comparatively long stipes, are alike slender and filiform. The 

 frond is remarkably membranaceous, subpellucid, and full of pellucid, closely- 

 packed dots, sparingly villous on both sides. The pinnse are opjmsite, auricled at 

 the base above. The terminal pinna is much elongated, and its base is confluent 

 with the superior bases of the uppermost pair of pinn;c. The venation slightly 

 anastomoses at the base of the jiinna;, so as to form areoles, showing an affinity 

 with Woodwardia and Doodia. The lines of fructification are close to the costa, 

 and the inferior line, at its base, diverges and follows for a little way the decur- 

 rent base of the pinnule, but does not extend to the rachis. The primary veins 

 (near the base) produce veinlets only on the inner side; the basal portion of the 

 pinnse next to the rachis is veinless. 



13. Bl. longifolium, H.B.K. ; rhizome short thick clothed 

 with fibres below, sparingly paleaceous above, frequently sto- 

 loniferous, stipites stramineous subfasciculate 3-4 inches to 

 a foot and more long, frond from 4 to 1^ foot long subdel- 

 toideo-ovate pinnated with usually few pinnee 5-7 or 10 

 (rarely 15-20) of which the terminal one is very long (and 

 generally the broadest) from 4-5 inches to 8 or 9 not unfre- 

 quently auricled below or coadunate with the nearest lateral 

 pinna and then petiolate some with 3 or 4 rounded lobes 

 (pinnatifid) below more or less obtuse at the very base, the 

 rest from 2 to 6 inches long by 3-4 lines broad, spreading 

 entire all of them linear-lanceolate sessile superior ones often 

 decurrent but free, of a dark-green hue satiny and sub-
