Some Notes on Charophyta Collected in The Netherlands West Indies, North Venezuela and Colombia

In 1930 Mr. P. Wagenaar Hummelinck made an excursion to Curacao, Aruba, and Bonaire with the main object of studying the land and freshwater fauna. In 1936 and 1937 he again visited these islands and, moreover, a.o. the island of Margarita off the Venezuelan coast, the Venezuelan peninsula Paraguana and the Colombian peninsula La Goajira (Wagenaar Hummelinck, 1940). In the various inland-waters also Algae and Phanerogams have been collected. The aquatic Phanerogams were described by Van Ooststroom (1939); the Charophyta will be the subject of the present paper.

As a result of these trips only two species of Chara were collected, one of which, viz. C. fibrosa , was new for the area under discussion. No representative of the other Charophyta genera was detected. Though several species are recorded from the north coast of South America (cf. Braun, 1858; Braun & Nordstedt, 1882), so little is known of the Charophyta of the Netherlands West Indian islands that it is worth publishing these few notes. Moreover, a number of ecological data were gathered, which are enumerated at the same time.
