SPECIES INQUIRENDAE 
ASPLENIUM PELLUCIDUM Lam. Encyc. 2: 305. 1786 
TYPE LOCALITY unknown. 
DISTRIBUTION: Malaysia-Polynesia. 
SPECIMENS EXAMINED: Ex Herb. Kunth; Meyen B. 
One specimen with auricled pinnae 52-jugate, and correspond- 
ing in other respects to A. pellucidum Lam. is in the Berlin Her- 
barium and was originally in Kunth’s Herbarium given by Dr. 
Meyen in 1833. The specimen is no doubt correctly named but 
correctness of the locality seems doubtful.

TYPE LOCALITY: Wailupe, Oahu. a 
DISTRIBUTION: Known from type locality only.

This is represented by a single sterile specimen at Berlin, but 
Hillebrand’s description proves that this is not his entire collection — 
of the plant. It may be a teratological form. 
ASPLENIUM KNUDSENII Hilleb. Fl. Haw. Is. 601. 1888 
No specimen so labelled or corresponding to Hillebrand’s :
