nimiuni fere huic convenit; pro certo itaquc species esse distinctas affirniare 

 noluerim, licet hucusque tantas rainificationis differentias in una cadcnique specie 

 obvenire hand obscrvaverim." Our plant is remarkable for tlie barsh and cori- 

 aceous fronds, prominent venation, mucronate segments, and su))spinulose serra- 

 tures. It bas also tbe spinules so common in tbe group to wbicb Pt. quadriaurita 

 belongs, and a small plant of tliis has exactly the same ramification as tbe ordi- 

 nary form of tbat species ; that is to say, subdeltoid, ternate (from the two lower 

 pinna being opposite, and larger than tbe rest, and compound), with one or more 

 pinnae, of wbicb those on the inferior side are longer than those of the superior 

 (unequally pinnate). In texture, and general habit, this species is allied to 

 Pt. Jamesoni and mxiricata and coriacea, but it wants the curiously muricated 

 rachises and costa of those species, though there is an approach to that in the 

 stipes being rough at the base. 



56. Pt. (Eupteris) Gaudichmidii, Ag. ; " fronds ternate, 

 branches subsimple pinnate, pinnae subpetiolate deeply pin- 

 nato-partite, segments triangular-lanceolate serrated mucro- 

 nate, veins forked, the inferior basal vein arising from the 

 costa and the superior one axillary extending to the margin 

 above the sinus." — Ag. S]}. Gen. Pterid. p. 42. Pt. palustris, 

 Gaud, in Freyc. Voy. p. 391 {excl. synonym.). 



Hab. Rio Janeiro, Brazil, Gaudichaud, Lund. — " Stipes on the superior side 

 brownish, scaberulous, tripartite. Branches elongated, with numerous pairs of 

 pinnas (14-16). Pinnae 3-4 inches long, about an inch and a half [ungue et 

 dhnidia vice latiores) wide, almost pinnatisect or deeply piunato-partite. Segments 

 lanceolato-falcate, subdecurrently confluent at the base, sharply serrated, the 

 terminal tooth mucronate. Substance rigid, coriaceous." This description suffi- 

 ciently accords with our preceding species, Pt. deflexa, Lk. ; so that Agardh's 

 views of the very close affinity of the two plants, expressed under the latter 

 species, may be considered correct. 



57. Pt. (Eupteris) pe/lucens, Ag.; fronds ample membra- 

 naceous ternately divided lateral divisions as well as the 

 intermediate ones mviltipinnate, pinnae shortly petiolate lan- 

 ceolato-acuminate long-caudate at the apex deeply almost to 

 the rachis pinnatifid, segments spreading oblong-subquadrate 

 obtuse subtruncate approximate sharply toothed at the 

 apex, the base decurrent glabrous, sori lateral on the seg- 

 ments never extending to the sinus nor to the apex, veins 

 rather remote all forked basal ones arising from the axil 

 of the costula and extending to the margin much above the 

 sinus, stipes and rachis brown or stramineous smooth. —
