The top specimen in the folder appears to be typical West Coast C. dioica (prob. introgressed w. C. squalida Hook.f.)
The lower piece is Stewart Island C. traillii - probably the locality is a mistake.
[Unknown]
Supplementary remarks:
The "lower piece" has been removed from this sheet and transferred to CHR 567450 Leptinella traillii.
