To //. Kdiidernii I i)i()visionally reler anolhcr .smaller spccimen 

 liom about the same localily (no. 55): most sterile leaves are not 

 materially diiicrent Irom thosc ot typical //. Kaudernii biil larger, 

 on stalks 1 — 3 cm, willi lamina 2 — 4 cm long and hroad and 

 somewhat more incised, bnl some other sterile leaves are etpial to the 

 lertile ones in size, with stalks iipto <S cm long, llie lamina more 

 divided with cnneale primary and seconchiry segments: lertile la- 

 mina much contracted, sori smaller than in H. Kmidcvnii wilh a

This form comes very ncar to the Polynesian H. botrijchioides 

 l^raek., \vhich sjjccies Christ has recordcd from ('.elebes bnl appa- 

 lently by mistaking the trne H. hotnjchioide.s. This specics is 

 scarccly well understood, at least the figure given })y Baker (Hook. 

 le. plant. t. 1G21) secms rathcr different from that of BRACKEXRnJGK 

 (U. S. Expl. Exp. 16. t. 32 f. 2), still both represent forms con- 

 siderably larger Ihan the form here described and recede bcsides 

 in smaller details.
