THE CAPE SABLE REGION OF FLORIDA 



bay. There, as in all the neighboring hammocks, the 

 mahogany or Madeira-redwood (Swietenia Mahagojii) 

 is exceedingly common. The bay and hammock were 

 long ago named for this tree, which occurs there both 

 large and small. Many large trees were cut out long 

 ago and many have been washed away from the ever- 

 changing shore line. 



We started in two row boats at sunrise the following 

 morning for the western end of the bay about two miles 

 distant and soon located the palm we sought. We found 

 it growing in great clumps, its fishpole-like stems com- 

 monly over thirty feet in height. The day we spent dig- 

 ging palms and exploring the Madeira hammock. Much 

 of interest was encountered. There, the sugar-berry 

 (Celtis mississippiensis) reaches its southernmost sta- 

 tion. A representative of a group of tropical bonesets 

 ( Osmia frustrata) , hitherto known only from the Florida 

 Keys, was there in abundance. There, too, we found the 

 large epiphytic cactus discovered in the Cuthbert Lake 

 region. As far as it was observed, it always grew well 

 above the ground on both living and dead tree-trunks. 

 The dense hammock also yielded an apparently new vine, 

 a kind of Tournefortia ; but; unfortunately, it was devoid 

 of both flowers and fruits. It is a pleasure to report the 

 rediscovery of our rarest, and a showy, passion-flower 

 (Passiflora pallens) . It grew in great quantities, cover- 

 ing the trees with its variegated blossoms and pendulous 

 green and purple fruits. This plant, it may be mentioned 

 in passing, was once found in the now extinct Caldwell 

 Hammock on the Everglade Keys. While in the Ma- 

 deira hammock, we were only a few miles distant, as
