16*, LiNDSATA MADAGASCAKIEKSIS, Bakevy xi. sp. Stipes (in- 

 complete) glossy, brown, naked, Frond deltoid, bipinnate, mem- 

 branous, brigbt green, glabrous, 5-6 in. long and broad. Lower 

 pinnse the largest, lanceo]ate, 2-3 in, long, 1-1^ in. broad at the 

 base. Pinnules cuneate or rhomboid, |-| in. broad, the lower 

 ones shortly petioled, entire on the inner and lower borders, 

 regularly rounded or somewhat angled for the rest of the edge, 

 and irregularly denticulate. Veins few, distant, free, dichoto- 

 mously forked. Sori distinctly intramarginal, the inner valve of ^

altered denticulate upper and outer edge of the pinnule produced 

 the breadth of the sorus beyond it. 



We received a small specimen of this in 1874 from the interior 

 of Madagascar, from Lady Barkly, gathered by Mr. Cameron. The 

 general habit of the plant is completely that of Z. fiahellulata^ in 

 which the sorus is marginal and the two valves of the involucre 

 are of equal breadth. 



Var. INTERMEDIA, BctTcev, Pinnules again divided into cuneate 

 tertiary segments |-J in. broad at the tip. 



Var. DAVALLioiPEs, Baker. Frond decompound, the pinna ^ 



more deltoid than in the type, cut up entirely into laxly disposed 

 ultimate segments |-1 line broad at the tip, and the sori and in- 

 volucre just those ot DavalUa, § Odontoloma. 



Bears the same relation to the type that the Ceylonese Bavallia 



scTiizophylla^ Baker, Syn. Fih edit. 2, p. 468, bears to Lindsaya 

 tenera^ and completely connected with the type by Miss Gilpin's 

 fine set of specimens. 



LoNCHiTis PUBESCENs, Willd. The typical form, in addition 

 to L. madagascariemisy Hook., aind L, polypus. Baker, both of 

 which are copiously represented in this collection. ' ^ 



13*. Cheilanthes (Adiantopsis) madagascaeiensis, Baker^ 

 n. sp. Stipe (incomplete), like the rachises, naked, glossy, cas- 

 taneous. Prond subdeltoid, 3-9 inches long, 2-7 in, broad, char- 

 taceous, green, glabrous, 3-4.pinnate. Pinnae deltoid, patent, 

 short-petioled, lowest the largest, 2-2| in. broad, produced on 

 the lower side. Pinnules oblong-deltoid, sessile or the lowest 

 shortly petioled; tertiary segments oblong, obtuse, more pro- 

 duced on the upper side at the base, with a few obtuse lobes. 

 Veins dichotomous, flabellate. Sori few, round, distinct, placed 



at the end of the ultimate lobes. Involucre glabrous, hemisphe- 

 rical .
