RUMPHIUS'S HERBARIUM AMBOINENSE 



The description otherwise applies to Barringtonia racemosa, 

 not to B. acutangula Gaertn., to which it has been reduced by 

 many authors. It was originally reduced by Linnaeus to 

 Eugenia acutangula Linn., in Stickman Herb. Amb. (1754) 14, 

 Amoen. Acad. 4 (1759) 124, Sp. PL ed. 2 (1762) 673; by 

 Lamarck, Encycl. 3 (1789) 197, to Eugenia racemosa Linn.; 

 by Loureiro, Fl. Cochinch. (1790) 410, to Meteorus coccineus 

 Lour., which is a possible synonym of Barringtonia racemosa 

 Blume ; and by other authors to Barringtonia acutangula Gaertn., 

 to Stravadia rubra Pers., to Stravadium rubrum DC., to Barring- 

 tonia rubra Blume, and finally by Miers to Butonica terrestris 

 Miers. 



RHIZOPHORACEAE 



The Rhizophoraceae described and figured by Rumphius are 

 obscure, and the actual status of the several species involved is 

 susceptible of various interpretations. The species actually rep- 

 resented in our Amboina collections are the forms commonly 

 known as Bruguiera eriopetala W. & A., B. caryophylloides 

 Blume, B. parviflora W, & A., and Rhizophora conjugata Linn. 

 By a strict interpretation of types, following the principles of 

 priority, most of these names must be discarded, Bruguiera 

 eriopetala W. & A. becoming B. sexangula (Lour.) Spreng., 

 B. caryophylloides Blume becoming B. cylindrica (Linn.) Blume, 

 and Rhizophora conjugata auct., non Linn., becoming R. cande- 

 laria DC. Species apparently described by Rumphius, but not 

 included in the Amboina collections at present available for 

 study, are apparently Ceriops tagal (Perr.) C. B. Rob. (C. 

 candolleana Arn.) and Bruguiera conjugata (Linn.) Merr. (B. 

 gymnorhiza Lam.). A number of species and synonyms must 

 be interpreted wholly or in part from the Rumphian figures and 

 descriptions. An attempt has here been made to select the 

 earliest valid specific name in each case and to adjust the syn- 

 onymy, but a future monograph of the group, based on very 

 comprehensive collections, may modify some of these conclusions.
