Hab. South Africa, Cape Colony to Natal, apparently frequent. — All the speci- 

 inens I possess of this species from South Africa are very uniform in character, 

 co])iously bi-tripinnate, the inferior secondary pinnules so large and conii)ound as 

 to give the primary pinnre an ovato-lanceolate form, and the fronds are lanceo- 

 late (not linear-oblong) in circumscription, tajjcring, with smaller pinni« at the 

 base. Hence I am disposed to keep the following species distinct from it. 



199. A. (Euasplenium) Borhonicum, Hook.; caudex thick 

 woody suberect clothed with b/o\vn ovate imbricated scales, 

 stipites 4-G inches long erect compressed, fronds a span to 

 14 inches and more in length oblong or linear-oblong shortly 

 acuminate nearly as wide at the base as in the middle pale 

 green bipinnate, primary pinntc patent broad-linear 1-2 

 inches long, pinnules nearly all linear or linear-subspathulate 

 straight or curved a few of the lower ones subcuneate and bifid 

 the lowest superior one broader and rather larger sul)palmate 

 once or twice forked or rarely subpinnate, all obtuse at the 

 points, veins solitary, sori solitary near the middle of the 

 pinnule or segment oblong or linear, involucres firm-mem- 

 branaceous nearly white, main rachis compressed, secondary- 

 ones alate. — Adiantum Borbonicum, Jacrj. Coll. iii. p. 286.

Ilab. Mascaren Islands ; Bourbon {Mus. Hist. N. Paris.), Carmichael, and 

 Mauritius (var. palmatum), Commerson. Ovolau, Feejee Islands .', Brackenridye. — 

 I possess specimens of this plant from Bourbon and Mauritius, collected by three 

 different botanists, and these I find to be so uniform in character, so ditferent 

 from any of my copious specimens of the Cape Aspl. rutaifolium, that I am dis- 

 posed to differ from those botanists who unite the two, and to agree with Will-
