390 53. BRAINEA. 54. MENISCIUM. 



Hab. Himalayas (up to 6,000 ft.) and Japan southward to Moulmein, the Philippines, 

 and Queensland. Oldham gathered in Formosa a form with the fronds quite entire. 



82. G. (Sell.) pinnata, Hk. ; st. subtufted, 6-12 in. 1., firm, erect, glossy ; 

 fr. 1. ft. or more 1., nearly as br., simply pinnate ; pinnce erecto-patent, 6-9 

 in. 1., -1 in. br., narrowed gradually to both ends, the lower ones stalked, the 

 edge nearly entire ; texture coriaceous ; rachis and both sides naked ; areolce 

 narrow, irregular, usually in two rows between the midrib and edge ; sori 

 oblong or linear, irregular, often confluent. Hk. Sp. 5. p. 161. Dictyogramme, 

 Moore. 



Hab. Fiji and Queensland to the Malay Isles. 0. ? subtrifoliata, Hk. Sp. 5. p. 152. 

 t. 298, from Fiji, is like this in habit and the shape of the pinnae, but they are only three 

 in number, and the veins join hardly at all. The fruit is not known. 



83. G. (Sell.) japonica, Desv. ; rhizome creeping ; st. 6-12 in. 1., glossy, 

 stramineous or chesnut-brown, naked ; fr. 1^-2 ft. 1., 1 ft. br., simply pinnate 

 or bipinnate at the base; pinnae 6-12 in. 1., 1-2 in. br., linear-oblong, acuminate, 

 entire, the lower ones stalked ; texture herbaceous ; rachis and both sides naked ; 

 veins close, usually twice forked, and joining once, the sori often on all of them 

 and extending from the midrib to the edge. Hk. Sp. 5. p. 161. Dictyogramme, 

 Presl. 



Hab. Japan and Formosa. Probably not really distinct from 0. javanica. 



84. G. (Sell.) podophylla 9 Hk. ; st. tufted, 6-8 in. 1., dark chesnut-brown, 

 glossy ; fr. 4-6 in. each way, deltoid ; lower pinnce much the largest, cut down 

 nearly to the rachis into oblong-lanceolate lobes, the lowest only prolonged and 

 pinnatifid ; texture herbaceous ; under surface finely pubescent ; veins copiously 

 reticulated ; sori in the outer half of the lobes. Hk. Sp. 5. p. 152. t. 296. 



Hab. Mexico and New Mexico. Probably a form of G. pedata, with which it quite 

 agrees in everything except venation. 



GEN. 53. BRAINEA, Hk. 



Sori continuous along transverse veins near the midrib and also produced 

 along the veins in the direction of the edge of the frond. A single subarborescent 

 Indian and Chinese species resembling Blechnum in general habit, but with naked 

 sori and the veins forming costular areolce. TAB. VI. f . 53. 



1. B. insignis, Hk. ; trunk 3-4 in. thick, the scales linear, ferruginous, f-1 

 in. 1. ; st. firm, 3-4 in. 1., naked, scaly only at the base ; fr. 2-3 ft. L, 8-12 in. br., 

 simply pinnate ; pinnce close, numerous, linear, finely serrated ; texture coria- 

 ceous ; rachis and both sides naked. Hk. Sp. 5. p. 162. Fil. Ex. t. 38. 



Hab. Hong-Kong and Khasya. 



GEN. 54. MENISCITTM, Schreb. 



Sori oblong or linear, occupying the connivent transverse veinlets. Fronds 

 simple or once pinnate. A small genus, almost confined to the tropics, with the 

 venation o/'Polypodium Goniopteris, from which it differs only by its elongated 

 or confluent sori. TAB. VI. f. 54. 



* Fronds simple. Sp. 1-2. 



1. M. simplex, Hk. ; rhizome firm, wide-creeping ; st. stramineous, slightly 

 pubescent, of the barren frond 4-6 in., of the fertile 1 ft. or more 1. ; barren
