been exterminated there, by human agency, before disappearing in 
Bermuda. 
Aside from the Palmetto, the most interesting of these endemic 
species are the Blue-eyed grass and the Maiden-hair Fern, both of 
which are very common and widely diffused. 
The Blue-eyed Grass* or “Lily” (fig. 33) grows in a variety of 
situations, both in good soil and on barren rocky and sandy hills, and 
even on the small barren islands. Its bright blue flowers, which are 
produced in abundance in spring, are often at least one-half an inch 
in diameter, being much larger and brighter blue than those of our 
New England species. The flower stems are often 8 to 10 inches 
high, but shorter in dry soil. 
The Maiden-hair Fern (fig. 34) grows in abundance in the cracks 
and crevices of cliffs, especially in those of the stone cuttings along 
the roadsides, forming tufts of very elegant and graceful foliage. 
The endemic species, according to Hemsley (Voy. Chall., Botany, 
i, p. 12) are as follows :—

6.— Localized Plants. 
Among the 156 species of land plants now considered nativef, about 
50 species are very restricted in their distribution, having been found 
* An ancient law, passed in 1669, required the destruction of two bad weeds, 
the ‘‘ Wire-weed” and ‘‘Lily.” It is thought that this Blue-eyed Grass was the 
plant meant by ‘‘Lily,” because there is no other native plant or weed that 
resembles a lily. If so it would prove that it was more abundant at that time 
than now, which is not unlikely. 
+ Hemsley reckoned 152 species as native (including eight species added in the 
Addenda). Lefroy considered a considerable number of additional species as 
native, some of which were more probably introduced. The additional species, 
introduced by man and considered as fully naturalized, are about 190, though 
many more are partially naturalized. So that the total number of flowering 
plants and ferns is about 350, exclusive of exotic cultivated plants, not natural- 
ized. To these may be added about 8 mosses; 6 Hepatice ; 32 lichens; 32 
Fungi. The algz include about 140 species.
