 glands.

 quoted as an authority for the Aspid. oUgocarpum of Kth. It differs from the 

 rivulorum of Raddi in the smaller (not a foot long) fronds, oblong-ovate in form, 

 that is, only having one pair of short basal pinna, and consequently no long at- 

 tenuated base to the fronds; the segments of the pinnje are of the same shape 

 as those of A. rivulorum., with six sori instead of eight, but equally destitute of 

 involucre. — Now tropical America, from the Atlantic to the Pacific, unfortunately 

 abounds in all sorts of intermediate forms, and I find it impossible, in the absence
