fertile fr. largei' and quite cut down to the racliis, with narrower, larger, and 

 more deeply-divided piuiuc ; texture subcoriaceous ; invol. membranous, incurved. 

 —Hk.Sp. 2. p. 132. t. 114. B. 



Hab. Bourbon, 



6. V.colamhina, Hk. ; barren fr. with slender, wiry, naked, polished, brownish- 

 black stems 6 in. 1., the frond not much over 1 in. each way, deltoid, cut down 

 to a broadly-winged rachis into two lobes on each side, the lowest of which is 

 much the largest and again deeply lobed and sinuated on the lower side ; fertile 



fr. on longer and stronger stems, 2-3 in. each wa}', cut down nearly to the rachis 

 into about four lobes on each side, the upper of which are linear and entire, the 

 lowest again deeply lobed below with a compound lower and simple upper linear 

 segments ; to'^«resul)Coriaceous, both surfaces naked ; veins inconspicuous ; sori 

 soon hiding the narrow spreading membranous invol. — P. lomariacea, /3, Hk. Sp. 

 2. p. 133. t. 112. — /3, vestita ; st. shorter, clothed throughout with brown fibriilose 

 scales. 



Hab. Brazil, summit of the Organ Mountains ; gathered by Mr. Gardner.— The alliance 

 of this seems to be with P. pilosa and geranicefolia. The barren fronds in size and 

 cutting much resemble those of the former. 



7. P. geraniasfuUa, Fee ; st. 6-9 in. 1., naked, erect, wiry, brownish-black, 

 polished, slightly scaly towards the base ; fr. 2-4 in. each way, deltoid, cut 

 down nearly to the rachis into 3 or 4 pintice on each side, of which tlie lowest 

 pair is much the largest, with the pinnl. on the lower side much larger than the 

 others and deeply lobed with linear-oblong segm.; rachis and costa dark-coloured 

 and polished like the stipe ; texture herbaceous, lateral veins once forked ; sori 

 in broad marginal lines. — Hk. Sp. 2. p. 132. Ic. PI. t. 915. Pteris concolor,

Hab. Tropical America, from Guatemala southward to Brazil and Peru ; Polyne.sian 

 Islands from New Caledonia northward to the Neilgherriea, N. China, and Subtropical 

 Australia, Mascaren Ihles, Zambesi Land, Angola, and Cape Colony. — This and the two 

 preceding agree in habit with Pteris pedata and CheUanthes Kirkii. From the former 

 their simple veins furnish the readiest mark of distinction. The plant from Australia, 

 sent by Dr. Mueller, gathered at Rockhampton by Messrs. Thozet and Dallachy, is not 

 unHkely distinct. It has fronds not more than 1 in. each way, resembling closely in 

 cutting and texture the barren fronds of the preceding. 



8. P. Tamhiirii, Hk. ; st. 6-9 in. 1., erect, naked, chesnut-brown, polished ; 

 fr. about 6 in. each way, deltoid, with three principal pinnce, the terminal one 

 cut down nearly to the rachis into several broad, opposite, lanceolate lobes, of 

 which the upper ones are entire and the lower ones larger and sinuated ; lateral 

 pinn(e with the loljcs on tlie upper side nearly entire, but those on the lower side 

 prolonged and again deeply lobed, the largest entire divisions about 1 in. deep, 

 ^ in. br, at the base ; texture subcoriaceous ; rachis polislied, brown like the 

 stipe ; under surf ace thinly coated with white farina ; invol. brownisli, continuous 

 but regularly crenated along the outer edge. — Ilk. Sp. 'I. p. 134. t. 129. A. 



Hab. Tambur Vallej', East Nepaul ; gathered by Dr. Hooker. A very distinct 

 species. 



9. P. deJtoilea, Baker; st. tufted, ]|-2 in. 1., erect, wiry, dark chesnut-brown, 

 naked, polished ; fr. H-2 in. each way, deltoid, bipinuate ; lower pinnce much 

 the largest, lanceolate -deltoid ; lowest 2)innl. cut down to the rachis below into 

 oblong lobes; ult. segm. oblong, or oliovate obtuse, aliout 2 lin. 1., I lin. br. ; 

 texture herbaceous or, when mature, subcoriaceous ; rachis and both surfaces 

 naked ; veins immersed ; sori in continuous lines; ««w^. membranous, crenate.
