 entire, about 2 in. 1., ^ in. br. ; upper lateral ones simple, not more than j in. 

 apart, and the base decurrent down to the next, the lower ones lanceolate-deltoid, 

 with a linear entire point and several short erecto-patent linear entire pinnl. on 

 each side ; texture subcoriaceous ; rachis and both surfaces naked ; veins obscure, 

 about | in. apart at the base, usually once forked j invol. narrow, mem-

Hab. Mishmee, N. Hindostan ; gathered by Griffith. 



14. P. madagascarica, Ag. ; fr. ample, bipinnate ; terminal pinna linear, the

 the lower ones 2 in. apart at the base, deflexed, oblong-lanceolate, about 6 in. 1., 

 4 in. br., with an entire terminal lobe and several stalked lateral pinnl. on each 

 side, which are about 2 in. 1., 2 lin. br., deeply serrated towards the point, 

 and spreading from the scabrous rachis at right angles ; texture coriaceous ; 

 veins conspicuous, about 1 lin. apart at the base and usually once forked 

 near the base ; invol. narrow, firm. Hk.Sp. 2. p. 171* t. 122. A. P. subserrata, 



Hab. Madagascar ; gathered by M. Bojer. 



15. P. mutilata, Linn. ; st. slender, erect, naked, polished, straw-coloured or 

 bright-brown, those of the fertile frond the largest (9-12 in.) and strongest ; 

 fr. about 6 in. each way, deltoid, with a linear entire point, several entire pinnce, 

 but the lowest pair lanceolate-deltoid, 4-6 in. 1., 3-4 in. br., with several linear, 

 erecto-patent pinnules on each side, the divisions of the barren frond shorter and 

 broader than those of the fertile one, not serrated, but mucronate at the point, 

 and furnished with a crisped white cartilaginous border ; rachis and both 

 surfaces naked and shining ; veins about 1 lin. apart at the base, simple or once 

 forked ; invol. narrow, membranous. Hk. Sp. 2. p. 164. t. 131. A.
