Sect. ii. Folia pedatisecta. 

 Abisjema beterophyllum, Blume, Bumphia, i. jj. 110. 

 "A foliis pedatisectis, segmentis (7-11) omnibus sessilibus oblongis brevi- 

 cuspidatis integerrimis simpliciter penninervigeris, intermedio bilatera- 

 libus minore." " Habitat in Japonia. Ab A. japonico, cui proximum est, 

 satis differre videtur segmento intermedio sessili, vicinis dimidio minori. 

 Hoc scilicet fere 1£ poll, longum, § poll, latum est, cum vicina satis 

 distantia duplo sunt longiora ac latiora, quae vero ad extremitntem 

 racbidis petiolaris sita sunt magis decrescunt." — Bl. 

 This species Engler, in DC.Monog. Phanerog.ii. p. 546, considers 

 to be a variety of A. Thunbevgii, Bl., but gives no indication as 

 to whether he had seen the type specimen or not; but if I am 

 right in my identification of this plant, it is, in my opinion, much 

 more nearly allied to A. tortuosum, Schott, and A. cuwatum, Kth. 

 Blume does not describe the inflorescence, neither do Schott or 

 Engler, so that it is probably unknown. 



The plant that I identify aB A. heterophyllum, Bl., is a speci- 

 men collected by Oldham (no. 817 !) in Surly Island, Korean 

 archipelago, where, he says (in a note attached to the specimen), 

 it is " rather common on the island, amongst grass." The peda- 

 tisect leaf has 15-17 sessile, oblong-lanceolate, shortly cus- 

 pidate segments, the middle one being about as long as the 

 first pair of lateral ones. Peduncle longer than petiole. 

 Spathe-tube 2 in. long, margins of the mouth not revolute; 

 limb 3 in. long, ovate-lanceolate, shortly acuminate, apparently 

 curved over the mouth of the tube. Spadix unisexual, the 

 flowering part reaching f~£ the length of the tube ; appendix 

 caudiform, 6-7 in. long, at first rather abruptly curved down- 

 wards, then recurving upwards, just as in A. tovtuosum. Synan- 

 dria stipitate, 2-4-anthered. Female spadix not seen. It will be 

 observed that the leaflets of this specimen are more numerous
