in the frond ; valves rounded, strongly ciliated. — II. pulchellum, IR. Sj/n. \. p. 

 91, in part. 



Hab. Andes of Ecuador and Columbia, ascending to 13,000 ft. — Closely allied to 

 II. Uneare in its manner of growth, but a much larger plant, with broader and shorter 

 segments. Tlie original H. pulc/iellum appears to be a small state of sencciim. Tliis and 

 the preceding are the only simply pinnate hairy species with divided pinnae. 



60. H. Cathcrince, Hk., MSS. ; St. 1-2 in. 1., erect, wiry, slightly ciliated ; fr. 

 2-3 in. 1., 1-1^ in. br., oblong, fully bipinnate ; main rachis free throughout, 

 slightly ciliated ; lower pinnae broadly rhoniboidul, cleft down to the racliis ; the 

 lower jrinnl. several times forked, with very narrow linear ciliated sepm. about 

 2 lin. 1. ; sori G or more to each pinna, terminal on the segments of the upper 

 pinnK! on both sides, considerably broader than the segments, the cuneate base 

 sunk in the frond ; the ciliated iHilves divided about halfway down. H. gratum, 

 Fee. 



Hab. St. Catherine's Peak, Jamaica, at an elevation of 5,000 ft., Wilson; Guadeloupe, 

 L' Herminier . — A small, neat, deeply-cut plant with inconspicuous hairs. The Guade- 

 loupe plant was distributed by M. J'ee as H. protrusum, Hook., which belongs to the 

 glabrous section, and is a form of H. jiolyanthos. 



51. H. Fastoensis, Hk., MSS. ; sf. 4-G in. 1., stout, erect, densely villose ; fr. 

 6-12 in. 1., 4-G in. br., ovate-acuminate, fully bipinnate ; rachis strong, erect, 

 densely clothed with ferruginous hairs ; pintuu ovate-lanceolate, recurved ; lower 

 pinnl. 1 in. or more 1., divided down nearly to the costa into very long narrow 

 linear segments, hairy principally on the rachis and margin ; sori 12 to 20, ter- 

 minal on and broader than the segments ; invol. orbicular, free, deeply 2-valved ; 

 i\\Q valves only ciliated, 



Hab. Volcano of Pasto, Andes of N. Ecuador, Jameson.— Th\s and the preceding (both 

 new species) are interesting, as showing a much more divided type of form in the frond 

 than was known previously in this section. 



*-s»* Leptocionium, Presl, V. D. B. ; margin of the frond spinidoso-dentate. 

 All the species are more or less compound. Sp. o2-71.

62. H. Tunhridgense, Smith ; st. ^-\h in. 1. ; fr. oblong-lanceolate, 1-8 in. 1., 

 ^-1 in br., pinnate throughout ; pinnce distichous, fiabellato-pinnatifid ; the lobes 

 linear, 1-3 lin. 1., and, as well as the usually solitary axillary suborbicular com- 

 pound invol. , conspicuously spinuloso-serrated ; the rachis and upper part of the 

 main stem winged. — HI: Sp. l.p. 9-5. Brit. Ferns, t. 43. — jS, H. IVilsoni, Hk. —

Hab. Regarding these two as British plants alone, we should pronounce them readily 

 separable by the characters given, which are taken from our two indigenous plants ; but, 

 looking abroad, we find them connected by every intermediate stage of gradation. Four- 

 teen species admitted or proposed by Van den Bosch cannot be clear'y separated. To 

 our a belong his Tunhridr/ense (Britain, Normandy, Corsica, Tyrol, Italy) ; Dregeanuni, 

 Presl (8. Africa) ; dimidiatum, Mett., (N. Caledonia) a7i^a)-c(icM7)i, Pr. (N. «. Wales 

 and V. D. Land) ; aspenUum, Kunze (Chili) ; and zeelandicum, V. D. B. (New Zealand). 

 Some of the Cape specimens are bipinnate, and have the lower pinnae fully 2 ia. 1. A 

 plant from the Falkland Islands has the piunte only once forked, or even simple : a grows 

 also in the Maiaritius, Madeira, the Azores, Jamaica, and Venezuela. To /3 belong 

 Wilsoni (Britain, Feroe, Norway) ; mcgachilum, Pr. (Brazil) ; vnilaterale, Bory (Bourbon); 

 Meyeri, Pr. (S. Africa) ; ajjine, Brack. (Fiji group) ; cupressifonne, Lab. (New Zealand 

 and Australia) ; Menzicsii (Falkland Islands, Staten Land, Cape Horn) ; and Mctttnii 

 (Chili) : and it grows also in Guatemala and the Peruvian Andes.
