the ground, whereas the foregoing sometimes grows upon trees ; the margin of the 

 fronds is even and the stipe smooth. It is found on the road to May-Day Hill. 



4. NODOSUM. KNOTTY. 



Filiv major in pinna s tantum divisa, varus, latieres, ohlongas, slri- 

 atas, ex adverso sitas, ct non crenatas. Sloanc, v. 1, p. 85, t. 41, 

 f. l. Simplex aassurgens, foliis oblongis oppositis, caule geniculato, 

 lineisfructijicationisfere contiguis. Browne, p. 93, A. 7. 



Fronds pinnate ; pinnas opposite lanceolate, quite entire. 



Root black, knobbed, tuberous, height two or three feet, upright, smooth; pinnas 

 long, striated ; fructifications in long straight parrailel lines, from the edge of the frond 

 to the rachis. Browne says it was very common about the barrack road in the moun- 

 tains of Westmorland, and lias the seed lines so closely disposed that it may easily be 

 mistaken for an acrostichum, at first \tcw. Sloane found it on Mount Diablo. 



5. SALICIFOLIUXI WILLOW-LEAVED. 



Lonchitis major, pinnis latinribus, teoiter denticulate, superiore la~ 

 tere auriculatis. Sloane, v. 1. p. 7S. 



Fronds pinnate ; pinnas sickle-lanceolate, crenate from the base, upwards angular. 



Height a foot and a half; stipe blackish, pinnas alternate, a third of an inch distant from 

 one another, on very short footstalks ; the mid lie pinnas are largest, being an inch 

 and a quarter long, and about half an inch broad at the base ; they end in a point, are 

 serrte at the edges, and are eared at the uppermost edge of each pinna. It grows in 

 inland woody paarts of the island. Sloane. 



6. DENTATUM ' TOOTH-LEAVED. 



Minus assurgens simplex,- .foliis oblongis, maigme inequali crenate, 

 Browne, p. 93, A. 5. < 



Fronds pinnate ; pinnas wedge-shaped obtuse, crenate emarginate. 



The simple erect asplenium with crenate leaves grows in great abundance about the 

 mountains in Liguanea, from six to eighteen inches in height, Swartz observes that the 

 A.pygmaeum of Li minis is nothing but a young plant of this species. 



7. RHIZOPHORUM. ROOTING: 



Lonchitis asplenii facie pinnults variis. Sloane, v. 1. p. 76. Simpler 

 minus re/iefens, Joliis oblongis crenatis et subauritis, sumnuiate 

 aphyllo rudicanti. Browne, p. 92, A. 4. 



Fronds pinnate, rooting at top ; pinnas ovate repand, somewhat eared ; very 

 small ones remote, quite entire. 



This plant is frequent in the mountains of Liguanea, seldom rising above ten or 

 twelve inches, and always found with the top bending towards the gronnd. Browne. 

 The young plant is simply pinnate ; but when fartheradvanced it isbipinnate. Swartz. 

 The face of this plant, and difference of the leaves, make it difficult toassign it a right place ; 

 for almost every stipe has several different kinds of pinna;. The leaves are sometimes 

 oblong auriculated, and disjoined, at other times they are auriculated, disjoined, towards 

 tbe top weak, trailing, and touching the ground, take root. Another variety is the leaves, 

 which are serrated or as it were made up of pinnules, making it seem a different plant.
