FLORULA CHELONESIACA ; OR, A LIST OF PLANTS COL- 

 LECTED IN JANUARY, 1874, IN THE ISLAND TORTUGA, 



VENEZUELA. 



By Dr. A. Eenst. 



The island Tortuga is situated between 10° 53' and 11° N.Lat, and 

 67° 28' and 67° 49' W., Paris, about fifty miles north from the coast of 

 Venezuela and fifty-two miles north-west from the island of Margarita. 

 It measures twelve miles from east to west, and six from north to 

 south. It is a raised coral reef, with an almost level surface, and has 

 a very narrow beach. The interior rises to 100 feet above the sea, and 

 is covered with numberless flakes of limestone, sometimes measuring a 

 square yard, and so hard and homogeneous that they sound like bells 

 when struck with a hammer. Between them there are here and there 

 patches of a more or less circular outline, covered for about two feet 

 deep by calcareous sand. On these, as well as in the furrows between 

 the limestone-flakes, there is a considerable, and sometimes even a 

 luxuriant vegetation, whilst but a few localities on tlie shore are 

 covered by Mangrove thickets. The western part of the island presents 

 a richer vegetation than the eastern part, probably on account of the 

 rather strong trade-winds. The island has no wells, but tliere is a 

 spot about the middle of the south coast where a slightly brackish 

 water filters from a crevice in the porous rock. There are no inhabi- 

 tants in the whole island, which is only visited now and then by fisher- 

 men, as there is plenty of good fish, turtles, lobsters {Palinurus 

 guttattis), and oysters (^Ostrea parasitica). 



I collected the following plants ; the vernacular names I learned 

 from the sailors of the small craft in which I made the excursion. 



1. Cakile aqualis, L'Her. Rare on the beach. 



2. Cqpparis Breynia, Jacq. This handsome shrub is called Olivo by
