JAMAICA FERNS. 



wide, 3 inches long, 1-1 i inches apart ; simple veins and long 

 diplazioid sori on the inferior one. The plants of the rinlicans 

 group are in hopeless confusion in large herbaria. 



AsPLExiUM (Dipl(izLHi)i) :sio:sTiGO-LVM, n. sp. — Stipites 8-12 inches 

 long, slender, erect, naked; fronds about 12 inches long, 4-5 inches 

 wide, bipinnate, not reduced at the base, the acuminate ajDices 

 pinnatitido-serrate; pinuc^e shortly pedicillate, 2 inches long, ^-1 

 i inch broad, gradually widening to the lowest pair, fully pinnate at 

 ^ the base, above this pinnatifid, the apex subeutire and sharply 

 serrated, the inferior side narrower than the superior and its basal 

 lobe absent ; pinnulae oblong, the lowest free one ovate, 5-7 lines 

 long, 2-3 lines wide, blunt, serrate ; texture thin ; colour pale ; 

 surfaces naked ; veins simple, or the inferior ones forked ; sori 

 about a line long, falling short of the rib and the margin ; involucre 

 flat, pale, thin and rather broad. — Herb. Kew. Gathered by R. N. 

 Sherring, Esq. Near A. se)inhastatuni , Kze., and A. Mildei, Kuhn. 



Xepkrodium incmim, Baker [Goniopteris strigosa, Fee.) 



Nephrodium texebricum, n. sp. — Stipites 6-8 inches long, erect, 

 grayish puberulous ; fronds 12-18 inches long, 4-7 inches wide, 

 gradually reduced each way, the acuminate apex pinnatifido- 

 serrate ; pinnae spreading, with an open space between them, 

 \J usually the lower ones, which pass into mere auricles, being sub- 

 distant, central 2|-3|- inches long, J-^ inch wide, truncate and 

 sessile, with a pair of enlarged lobes at the base, above these 

 seri'ate or slightly lobed, the latter rounded and 1 line wide and 

 deep, apices entire ; texture chartaceous ; colour dull, grayish ; 

 rachis and surfaces puberulous ; veins about four to a side, the 

 lowest opposite ones uniting in a vein to the sinus, where the next 

 pah* usually join it ; sori medial on the lower veins, forming one or 

 two rows along the costae ; involucre minute, soon obliterated. — 

 Herb. Kew. Gathered by R. N. Sherring, Esq., on the north side 

 of the Island. Near arbuscula and cDiihoineme, from which the 

 singular and uniform basal lobes separate it. 



Pobjpodium jinmwt, Klotzsch, is a broader plant than normal 

 rigesceiis, frequent at high altitudes, from which however it is 

 doubtfully distinct. 



PoLYPODiuM Sherringii, Bakcr, in lit., n. sp. — Stipites 

 , forming a dense tuft, short if any clear of the decurrent wings of 

 >\ the fronds ; fronds 1^-2 inches long, 3 lines wide, blunt at the 

 apex and narrowed at the base, cut into rounded broadish de- 

 current lobes, with an open oblique sinus between showing a clear 

 wing to the rachis ; rachis flexuose, buried under the pagina, the 

 latter eventually dropping away from it ; substance opaque, stiff ; 

 clothed with scattered dark brown hairs ; lobes about 1 line each 

 way, with a sorus to each near the rachis, borne on the spur at the 

 base of the short concealed vein. — Collected by the gentleman 

 after whom it is named in the Newton district of the Port Royal 

 Mountains. It is the most densely tufted of all the smaller 

 Jamaican species, and the stiff, thread-like rachises remain on the 

 plants after the pagina has dropped from them.
