THE VOYAGE OF H.M.S. CHALLENGER. 



From this table we learn that 109 speeies of the Bermudau flora also inhabit South- 

 Eastern North America, and within one of the same number inhabit the West Indies. 

 Farther, eighty-six of the Bermudan plants are common to the West Indies and continental 

 North America, or at least reach the keys of Florida. It is only a comparatively small 

 number of the eighty-six that does not reach the mainland of Florida, where there is a 

 much greater overlapping of the essentially North American and the West Indian elements 

 than was formerly suspected. A considerable number of the species common to the West 

 Indies and North America are as much at home on the coast of the South-Eastern States 

 as they are in the West Indies ; yet the bulk of these are West Indian types, and not found 

 north of Florida on the continent. 



To add to these there are twenty-three West Indian species in the Bermudas not hitherto 

 recorded, to our knowledge, from North America. They are : — 



Ascyrum hypericoides? Elceodendron xylocarpum, Sapindus saponaria, Rhadhicallis 

 rvpestris, Ipomcea jamaicensis, Ipomcea acuminata, Ipomcea villosa, Convolvulus jamai- 

 censis, Atriplex cristata, Peperomia magnolicefolia, Juniperus bermudiana, Spiranthes 

 toriilis, Typha angustifolia, Lemna trisulca, Cyperus odoratus, Cyperus rotundus, Dich- 

 romena pura, Rhynchospora florida, Pteris heterophylla, Aspidium coriaceum, Nephro- 

 dium amplum, Nephrodium molle, Nephrodium villosum. 



Most of the foregoing are represented in North America by closely allied species, and 

 some of them may yet be discovered in Florida. Sapindus saponaria is recorded by Sir 

 J. II. Lefroy as having sprung up from seed cast ashore in the Bermudas. The most note-
