412 PEECT SLADEN TEUST EXPEDITION 



12. Dryopteris Hornei (Baker), O. Kuntze ; C. Chr. Ind. 271. — Nephrodium Rornei, 

 Baker, Fl. Maur. 497. 



Mahe, Home, 182 ! Silhouette, Home, 685 ! 



Endemic. Tlie pubescence is peculiar, the costse and costulse above are rufous-tomen- 

 tose from short, articulated hairs (the tyj)ical pubescence of my subgenus Ctenitis) ; the 

 veins beneath are densely covered with very short and thick, appressed glandular hairs, 

 "which in well-preserved specimens are glossy, golden yellovr, in old specimens whitish, 

 meal-like. I remember only one species which shows a similar pubescence, viz. 

 1). chrysotricha (Baker), C. Chr., from Samoa, but in that the hairs are bright yellow. 



13. AspiDiUM PLEIOTOMUM (Baker), Kuhn ; C. Chr. Ind. 88. — Nephrodium pleiotomum, 



Baker, Tr. Eoy. Irish Acad. xxv. (1875), tab. 31 B; Fl. Maur. 500. 

 Mahe, Home. Silhouette, Gardiner ! 

 Also Madagascar, fide Baker. 



14 PoLYSTiCHUM ADiANTiFORME (Forst.), J. Sm. ; C. Chr. Ind. 578. — Aspidium capense, 

 Willd. ; Baker, Fl. Maur. 492. Asjndium coriaceum, Sw. ; Kuhn, Bot. v. Ost- 

 Afrika, 69. 

 Mahe and Silhouette, Gardiner ! Sometimes partially epiphytic. 

 Distribution. Australia and Southern Polynesia. South Africa and adjacent islands. 

 America from Cuba and Jamaica to Ftiegia. A common species in most oceanic islands 

 of the southern hemisphere. The numerous specimens collected by Gardiner are rather 

 different, especially in size ; some of them are scarcely more than bipinnatifid with a 

 lamina not more than 10 cm. long, but fully fertile. 



15. Leptochilus bipinnatifidus (Mett.), C. Chr. com)), nov. — Chrysodiimi bipinna- 



tifidum, Mett. ; Kuhn, Fil. Afr. 50. Acrostickmn repiandum, Baker, Fl. Maur. 514 

 (non Blume). 



Mahe, Boivin ! Gardiner ! Silhouette, near the summit, Gardiner ! 



Perhaps endemic. It is also recorded from Beunion {coll. Boivin) ; but Jac. de 

 Cordemoy has not seen it. All Boivin's specimens in the Museum of Paris seen by me 

 are from the Seychelles. 



I now think that this can safely be regarded as a species distinct from the Asiatic and 

 Polynesian L. ctispidatus, C. Chr. {Acrosticlmm repandimi, Blume). It differs in the more 

 deeply cut pinnae, which are truncate at the base, not cuneate, and in the more decidedly 

 scaly costse. The lowermost pinnae are rather unequal-sided, the upper ones decurrent 

 at the lower base, and the fertile jjiunse deeply cvit into bluntly rounded lobes. The 

 sterile fronds often have rooting tips. 



16. Oleandra articulata (Sw.), Presl ; Baker, Fl. Maur. 493 ; C. Chr. Ind. 466. 

 Mahe, Gardiner ! Silhouette, near the summit, Gardiner ! " Epiphytic, notable 



climber." 



Distribution. Through tropical Africa to Cape Colony, and especially common in the 

 South-east African islands.
