fertile fr. larger and quite cut down to the rachis, with narrower, larger, and 

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

 Hk. Sp. 2. p. 132. t. 114. B. 



Hab. Bourbon. 



6. P. columbina, 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 way, 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 ; texture subcoriaceous, 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 nbrillose 

 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 mnch resemble those of the former. 



7. P. geranicefolia, 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 pinnae on each side, of which the 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. PL t. 915. Pteris concolor, 

 Langs, fy Fisch. Ic. t. 21, oldest name. 



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

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

 Australia, Mascaren I*les, Zambesi Land, Angola, and Cape Colony. This and the two 

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

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

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

 unlikely 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. Tamburii, Hk. ; st. 6-9 in. 1., erect, naked, chesnut-brown, polished ; 

 fr. about 6 in. each way, deltoid, with three principal pinnae, 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 

 pinnce with the lobes on the 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 polished, brown like the 

 stipe ; under surface thinly coated with white farhia ; invol. brownish, continuous 

 but regularly crenated al&ng the outer edge. Hk. Sp. 2. p. 134. t. 129. A. 



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

 species. 



9. P. deltoidea, Baker; st. tufted, 1^-2 in. 1., erect, wiry, dark chesnut-brown, 

 naked, polished ; fr. l-2 in. each way, deltoid, bipinnate ; lower pinnce much 

 the largest, lanceolate-deltoid ; lowest pinnl. cut down to the rachis below into 

 oblong lobes; ult. segm. oblong, or obovate obtuse, about 2 lin. 1., 1 lin. br. ; 

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

 naked ; veins immersed ; sori in continuous lines ; invol. membranous, crenate.

Hab. Cape Colony, Burchell, 2033. Namaqua Land : gathered by Drege, and latterly 

 by the Rev. Mr. Whitehead.
