Four new ferns. 371 
acutis, superioribus adnatis, supremis confluentibus. Lobis late-rotun- 
datis, c. 7 mm latis, 4—5 mm longis, integris vel sinuatis. Venis copiose 
anastomosantibus more L. pubescentis Willd. Soris parvis, in sinubus 
rarius in marginibus sinuatis loborum sitis.

guin no, 28, Febr. 1910. (Typus in Herb. Principis Roland Bona- 
parte.) — „Par touffes poussant, sous les rochers ombrés et humides,“ 
Resembles. a reduced form of L. pubescens Willd., from which it 
differs by its small size, only once pinnate lamina, thin texture and not 
so villous stipe and rachis. 
3. Aneimia sessilis (Jeanpert) C. Chr., nov. spec. 
Syn.: À, tomentosa Sw. var. sessilis Jeanpert, Bull. Mus. nat. d’hist. 
nat., 1910: 408. 
Rhizomate bulboso, pilis rufis sericeis dense vestito. Stipitibus 
fasciculatis, decidue pilosis, folii sterilis 1—2 cm longis, fertilis ad 5 cm 
longis. Foliis fertilibus sterilia superantibus. Lamina ovato-oblonga, 
c. 5 cm longa, 3—4 cm lata, herbacea, ubique molliter pilosa, denique 
subdenudata, plus minusve minute glandulosa, bipinnatifida. Pinnis 
sterilibus 3—4 jugis, basalibus breviter petiolulatis, superioribus sessili- 
bus, oppositis, ovato-oblongis, apice obtuso dentatis, profunde lobatis; 
lobis 3—4 jugis, ovatis, obliquis, marginibus crenatis. Venis in lobis 
flabellatim dispositis, distinctis. Pinnis fertilibus brevioribus quam 
sequentibus sterilibus vel subaequalibus, brevissime petiolulatis (petiolo 
1—2 mm longo), parum erectis vel fere horizontalibus.

„plante étalée en forme de rosette aplatie, poussant sur rochers humides“, 
leg. H. Pobéguin, Jan. 1910, no. 15. (Typus in Herb. Principis Roland 
Bonaparte.) — A specimen from Hte Dahomey, Mt. Atacora, entrée 
des grottes de la falaise de Natitingon, 400—600 m, leg. Aug. Che- 
valier, 21. Juni 1910, no. 24164, is apparently the same. 
An interesting discovery, which adds a third (or fourth) species of 
Aneimia to the African flora. The species is certainly closely related to 
A. Schimperiana Pr. from Abyssinia and Angola and to the American A. 
fulva (Cav.) Sw., but it is well-marked by the short and very shortly 
stalked fertile pinnae, which scarcely are so long as the following pair 
of sterile pinnae. It is possible that the specimen from Dahomey, which 
is poorly fructiferous, belongs to A. Schimperiana. 
4. Athyrium paucifrons C. Chr., nov. spec. 
Rhizomate oblique-erecto. Foliis paucis (4—8), subfasciculatis, 
Sterilibus minoribus saepe perparvis breviter stipitatis, fertilibus longiori- 
bus, longe stipitatis sterilia multo superantibus. Stipitibus basi nigra, 
crassa, squamis ovatis tenuibus sparse onustis, sursum stramineis, gra- 
cilibus, nudis, glabris, fol. sterilium 2-8 cm longis, fertilium usque ad 
25 cm longis. Rachibus gracilibus, stramineis, supra minute glandu- 
losis, squamis minimis perpaucis instructis. Lamina folii fertilis an- 
£uste lanceolata, 25—30 cm longa, medio 7—8 cm lata, ad basín leviter
