Amboina, Robinson PL Rumph. Amb. 72, along the seashore near the 

 town of Amboina, August 8, 1913; Gelala, PI. Rumph. Amb. 71, September 

 28, 1913, on hills near the seashore, altitude about 6 meters, locally known 

 as manga berabu. 



Arbor lactaria and Arbor lactaria terrestris certainly rep- 

 resent but a single species, and that is Cerbera manghas Linn., 

 as actually described by Linnaeus from Osbeck's Javan specimen. 

 Arbor lactaria Rumph. was originally reduced by Linnaeus to 

 Cerbera manghas Linn., in Stickman Herb. Amb. (1754) 10, 

 Amoen. Acad. 4 (1759) 122, in which he was followed by many 

 early authors. Valeton, Ann. Jard. Bot. Buitenz. 12 (1895) 

 245, has proposed to keep Cerbera odollam Gaertn. (C. manghas 

 Linn.) and Cerbera lactaria Ham. distinct, but after a careful 

 consideration of the descriptions and of a large series of speci- 

 mens I am now of the opinion that but a single species is rep- 

 resented. I deliberately reinstate the Linnean name, Cerbera 

 manghas Linn., as this is manifestly the species amply described 

 by him in the original description of the species from Osbeck's 

 specimens. Some of the references added by him include Taber- 

 naemontana dichotoma R. Br.* 



PARAMERIA Bentham 



PARAMERIA BARBATA (Blume) K. Schum. in Engl. & Prantl Nat. 



Pflanzenfam. 4 2 (1895) 162. 

 Parsonsia barbata Blume Bijdr. (1826) 1042. 

 Ecdysanthera barbata Miq. Fl. Ind. Bat. 2 (1857) 451. 

 Cortex consolidans Rumph. Herb. Amb. 5: 30, t. 19. 



This species is not represented in our Amboina collections. No 

 previous reduction of Cortex consolidans Rumph. has been sug- 

 gested other than that it belongs in the Apocynaceae. The 

 figure, which is apparently an excellent one, and the description 

 agree closely with the characters of Parameria glandulifera 

 (Wall.) Benth., of P. philippinensis Radlk., and of P. vulneraria 

 Radlk., all of which are apparently forms of a single species. 

 Blume's specific name, being the oldest, is here retained.
