THE CAPE SABLE REGION OF FLORIDA

morning and secured quantities of the rare cactus we had 

 located there during the earHer part of our cruise. This 

 plant, a species of Cephalocereus, with garlic-scented 

 flowers, is nearly or quite similar to the one heretofore 

 definitely known only from Key West. It was observed 

 but not collected in a hammock on Lower Matecumbe 

 Key several years ago by a member of our party. 



Having devoted as much time as could be spared to 

 this locality we moived on to Umbrella Key (Windlys Is- 

 land) and Long Island. The former island is higher 

 than 'the other keys, and most of it in the form of rock 

 has gone to build the larger part of the Key West Ex- 

 tension of the Florida East Coast Railway. The main 

 object of our visit to this island was to search for one of 

 our rarest trees, the white-ironwood, Hypelate trifoliata. 

 We were successful in finding a few trees in the small 

 remnants of the once beautiful hammock. Some of 

 these trees had a maximum trunk-diameter of fully two 

 feet. Proceeding northward we reached Jewfish Creek 

 about sundown and spent the night there. The next day 

 was to find us safe in Miami. 



It was after a period of five days, during which our 

 living and dried specimens were cared for, that a cruise 

 to the Madeira Bay region was undertaken. This, like the 

 cruise just completed, was partly for the purpose of find- 

 ing the saw-cabbage palm (Paurotis Wrightii). An 

 early start on Saturday, April 15, and a continuous run. 

 without a stop of the engine, brought us to the mouth of 

 Madeira Bay at the southern end of the Florida penin- 

 sula about on hour before sunset. This hour was devoted 

 to exploring a hammock island near the mouth of the
