POLYPODIACEiE. 



Tribe III. PTERIDE^l, J. Sm. 



36. HYPOLEPIS, Bernh., Presl 



1. Hypolepis tenuifolia, Bernh. 



K rhizomate subgloboso; frondibus amplis tri-quadripinnatis, lacmiis 

 oblongis obtusis, inferioribus subpinnatifidis, superioribus coadunatis; 

 rhachi pilosa ; sorisparvis; indusiis oblongis subrenif or mibus. 



Hypolepis tenuifolia, Bernh. ex Presl, Tent. Pterid. p. 162, t. 6, f. 24. 

 Cheilanthes arborescens, Sw. Syn. Fil. p. 139, t. 336 ; Willd. Spec. PI. 5, p. 462. 



Hab. Tutuila, Samoan Group. 



Fronds very large, from 3 to 5 feet high, from a globular rootstock, 

 somewhat rigid, 3 to 4 times divided, with broad spreading pinnae. 

 Pinnules pinnate at the base, pinnatifid towards the point : segments 

 linear-oblong, obtuse, dentate-serrate ; the inferior ones pinnatifid, and 

 bearing on their margin from 2 to 6 or sometimes even 8 small sori. 

 Ehachis of the primary and secondary divisions rufous-pilose on both 

 sides, and sulcate on the upper one Indusia oblong, sometvhat reni- 

 form. 



There is little doubt of this being the Glieilantlxes arborescens of 

 Swartz (Lonchitis tenuifolia, Forst.) ; but we are at a loss to know 

 what could have induced both Forster and Swartz to describe the 

 plant as arborescent. 



2. Hypolepis dissecta. 



H. rhizomate repente; frondibus amplis tri—quadripinnatis, laciniis 

 lineari-oblongis obtusis subtus pubescentibus, inferioribus subpinnati- 

 fidis, superioribus coadunatis; stipitibus rhachibusque leviter rufo- 

 pubescentibus ; soris parvis solitariis.
