Colysis Spectrum, also the beautiful Cibotium Menziesii, were 
sent to the Royal Gardens, Kew, from the Sandwich Islands by 
Dr. Hillebrand, in 1863.

1*. C. Fortunei, J. Sm. Fronds 1— II foot long, pinnate ; 
pinnae lanceolate, falcate, acuminate, 2—3 inches long, 
1 inch wide, entire, the base oblique, the inferior 
rounded, the superior truncate and subauriculate. 
Costa ebenous, upper surface dull, unreflecting. Sort 
numerous. — Japan. 
Obs. — In Herbaria, specimens of this cannot readily be dis- 
tinguished from C. falcatum ; but on seeing living plants stand- 
ing side by side, the difference is evident ; C. Fortunei being a 
smaller-growing plant, thinner in texture, and not lucid and 
reflecting light, as C. falcatum. 
70. ASPIDIUM. 
3*. A. polymorphum, Wall . ; Hook. Sp. Fit. 4, p. 54 ( exclude

3 ## . A. Barteri, J. Sm. Vernation erect. Fronds pinnate, 
1-2 feet high; pinnae linear-lanceolate, 6-7 inches 
long, 1-1| broad ; the lower pair sometimes binate, 
or auriculated on the lower margin. Sori regularly 
biserial between the primary veins. Indusium small, 
fugaceous. Aspidium polymorphum. Wall, ac- 
cording to Hook. Sp. Fil. 4, p. 54. — West Africa, 
Fernando Po. 
Obs. — This is quite distinct from the preceding species. 
In A. Barteri the sori are perfectly serial, whereas in A. poly- 
rnorpkum the sori are scattered.
