collections. The suggested reduction of the two forms described 

 under Mangium caryophylloides Rumph. is after Hasskarl, Neue 

 Schliissel (1866) 57, but Ceriops tagal is an older name than C. 

 candolleana Arn. Blume, Mus. Bot. 1 (1849) 143, suggests that 

 Mangium caryophylloides II may be the same as Ceriops zippel- 

 iana Blume, and that Mangium caryopylloides III may be the 

 same as Ceriops forsteniana Blume, but both of Blume's species 

 are apparently merely forms of the common and widely dis- 

 tributed Ceriops tagal C. B. Rob. Blume also suggests that 

 Mangium minus Rumph., Herb. Amb. 3: 106 quoad descr., excl. t. 

 69, may be Ceriops zippeliana Blume, which may be the correct 

 disposition of the description; the plate is considered under 

 Bruguiera conjugata (Linn.) Merr. and under B. cylindrica 

 (Linn.) Blume (p. 388).

While both plates given by Rumphius are very crude, they 

 unmistakably represent the form with short peduncles bearing 

 usually two flowers. The description, however, may include also 

 the allied Rhizophora mucronata Lam., which is distinguished 

 by its longer peduncles and more numerous flowers. By Lin- 

 naeus it was erroneously reduced to the American Rhizophora 

 mangle, in Stickman Herb. Amb. (1754) 13, Amoen. Acad. 4 

 (1759) 123, Syst. ed. 10 (1759) 1043, Sp. PI. ed. 2 (1763) 634, 

 in which he was followed by Lamarck, Willdenow, Burman f., 

 Roxburgh, and other authors. Blume, Mus. Bot. 1 (1849) 132, 

 placed it under Rhizophora mucronata Lam. with the comment 

 "descriptio satis bona, figurae minus rectus !," while Walpers, 

 Repert. 2 (1843) 70, placed it under Rhizophora conjugata Linn. 

 Rhizophora candelaria DC. is a composite species to be inter- 

 preted from Mangium candelarium Rumph. and Pee-kandel 

 Rheed. Hort. Malabar. 6 : t. SU, Rheede being cited first, Rumph- 

 ius second; but as the specific name is manifestly taken from 

 Rumphius, while the description given by de Candolle applies 

 better to the form generally interpreted as Rhizophora conjugata 

 auct. (non Linn.) than to R. mucronata Lam. Rheede's figure 

 is considered to represent Rhizophora mucronata Lam.
