RHIZOPHORACEAE 



389 



Rhizophora cylindrica Linn, must be interpreted solely by 

 Cari-Candel Rheed. Hort. Malabar. 6 : 59, t. 33, which most 

 authors agree represents the form described by Blume as Bru- 

 guiera caryophylloides (Burm. f.) Blume. Mangium minus 

 Rumph., as figured, is manifestly a composite species, the at- 

 tached flowers and figures A and B having been copied by 

 Burman in editing Rumphius's work from Cari-Candel Rheed. 

 Hort. Malabar. 6: t. 33. The leafy branch and fruits, excluding 

 the attached flowers and figures A and B, and the description 

 for the most part are probably referable to Bruguiera gymnor- 

 hiza Lam. (B. rheedi Blume) . It was reduced by Linnaeus to his 

 Rhizophora cylindrica, in Stickman Herb. Amb. (1754) 12, 

 Amoen. Acad. 4 (1759) 123, Syst. ed. 10 (1759) 1043, Sp. PI. 

 ed. 2 (1762) 635, in which he was followed by Burman, La- 

 marck, Willdenow, and other authors. Mangium caryophylloides 

 Rumph. is the basis of Rhizophora caryophylloides Burm. f., 

 Fl. Ind. (1768) 109, from which again Bruguiera caryophylloides 

 Blume and Kanilia caryophylloides Blume must be interpreted. 

 The figure is not good, but is undoubtedly referable here, while 

 the description applies closely to the form generally named Bru- 

 guiera caryophylloides Blume=Z?. cylindrica (Linn.) Blume.

 along tidal streams, locally known as mangi mangi. 



Mangium digitatum Rumph. has been reduced by some authors 

 to Bruguiera gymnorhiza Lam. and by others to B. cylindrica 

 Blume. It seems, however, to be the species commonly known as 

 Bruguiera eriopetala W. & A., which I have here reduced to the 

 older Bruguiera sexangula Poir. (Rhizophora sexangula Lour.) . 



The generic description given by Linnaeus, Gen. PL (1754) 

 202, is unmistakably Rhizophora as at present understood, 

 although the first two species cited in his Species Plantarum 

 (1753) 443 are representatives of Bruguiera, the third a 

 Kandelia, and the last two true Rhizophorae. The first species, 

 Rhizophora conjugata Linn., has been misinterpreted by most 

 authors since its publication, but it has page priority over 

 Rhizophora gymnorhiza Linn. Trimen * states :
