 central region of Brazil, about Caraca and Ouro Preto : — 



y'^ 51.-''Adiantuin Sense, n. sp. — Stems densely tufted, very 

 slender, short, naked, castaneous. Frond simply pinnate or sparsely 

 bipinnate, lanceolate or lanceolate-deltoid, 1^-2 in. long, bright 

 green, glabrous ; main rachis very slender, naked, zigzag, cas- 

 taneous. Lower pinn® largest, with at most only 3-4 distant 

 segments. Segments remote, shortly petioled, at most \ in. long 

 and broad, cuneate and entire in the lower half, rounded and more 

 or less deeply lobed on the margin of the upper half. Veins

 segment. Indusium pale drab, glabrous, membranous, persistent. 

 — 6^/rt;eioM 15723! Intermediate between tremulum and the dwarf 

 forms of citneatum, but much less compound than the latter. 

 Named, at the request of Dr. Glaziou, after Mr. Joaquim de Costa

 Mines at Ouro Preto. 



187.'''Nephroclmm (Eunephrodium) devolvens, n. sp. — Stipes 

 4-6 in. long, slender, grey, fragile, naked. Frond oblong-lanceo- 

 late, 15-18 in. long, 5-6 in. broad, bipinnatifid, membranous, 

 green and finely hairy on both surfaces ; rachis grey, straight, 

 fragile, pubescent. Pinnae numerous, lanceolate, sessile, truncate 

 at the base, those of the centre and base of the frond all about 

 equal in length, 3-4 in. long, f-1 in. broad, cut half-way down to 

 the midrib into parallel oblong segments ^ in. broad ; lower pinnae 

 very much deflexed and narrowed on both sides towards the base. 

 Veins pinnate, 8-9 -jugate, simple, about the two lower pairs anas- 

 tomosing at the tip. Sori small, round, medial. Indusium small,

 texture, densely hairy on both surfaces and all the rachises. Lower 

 pinnae many subequal, lanceolate or oblong-lanceolate, 2-4 in. long, 

 lowest much reflexed ; final segments oblong, obtuse, contiguous, 

 faintly crenate, l-12th in. broad. Veins sparingly pinnate in the 

 final segments. Sori globose, subcostular. — Glaziuu 15734 ! 

 Recalls in general habit the most hairy forms of Lonchitis pubescens. 



Anemia ohlongifvlia Sw. — Besides the type. Dr. Glaziou sends 

 two strikhig varieties, lanosa, with leaves of coriaceous texture, 

 leaflets of the basal leaves 7-8-jugate, base of the tuft enveloped in
