RUMPHIUS'S HERBARIUM AMBOINENSE 



Linnaeus to Dolichos erosus Linn., in Stickman Herb. Amb. 

 (1754) 23, Amoen, Acad. 4 (1759) 132, Syst. ed. 10 (1759) 1163; 

 but in the second edition of his Species Plantarum, ed. 2 (1763) 

 1021, he placed it under Dolichos bulbosus Linn., which is 

 manifestly a synonym of the earlier D. erosus Linn. By most 

 recent authors it has been considered to be Pachyrrhizus angula- 

 tus Rich., but this name must be abandoned for the much earlier 

 Linnean one. 



PSOPHOCARPUS * Necker 



PSOPHOCARPUS TETRAGONOLOBUS (Linn.) DC. Prodr. 2 (1825) 403. 

 Dolichos tetragonolobus Linn, in Stickman Herb. Amb. (1754) 23, 



Amoen. Acad. 4 (1759) 132, Syst. ed. 10 (1759) 1162, Sp. PI. ed. 



2 (1763) 1020 (type!). 

 Botor tetragonoloba O. Kuntze Rev. Gen. PI. 1 (1891) 162. 

 Lobus quadrangularis Rumph. Herb. Amb. 5: 374, t. 133. 



This well-known species is not represented in our Amboina 

 collections, but is doubtless still cultivated there as it is in most 

 parts of the Indo-Malayan region. The Rumphian figure and 

 description are the whole basis of Dolichos tetragonolobus Linn., 

 and it has been consistently cited by all authors under that 

 name or its modern equivalent, Psophocarpus tetragonolobus DC. 



DOLICHOS Linnaeus 



DOLICHOS LABLAB Linn. Sp. PI. (1753) 725. 



Dolichos lignosus Linn. 1. c. 726. 



Dolichos albus Lour. PL Cochinch. (1790) 439. 



Lablab vulgaris Savi Diss. (1821) 19. 



Lablab perennans DC. Prodr. 2 (1825) 402. 



Cacara Rumph. Herb. Amb. 5: 378, t. 136. 



Cacara alba Rumph. Herb. Amb. 5: 380, t. 137. 

 Amboina, Koesoekoesoe sereh, Robinson PI. Rumph. Amb. 552, August 23, 

 1913, locally known as kakara puti. 



The specimen represents one of the several distinct forms of 

 this variable species; in the shape of its pod it is somewhat 

 different from both of the forms figured by Rumphius. Two 

 distinct forms are figured and described by Rumphius: Cacara, 

 with purple flowers, and Cacara alba, with white flowers. These 

 are now, however, generally considered to represent a single 

 species. Cacara was originally reduced by Linnaeus to Dolichos 

 lignosus Linn., in Stickman Herb. Amb. (1754) 23, and has 

 been cited by various authors under the names Dolichos altissi- 

 mus Lour, and Lablab vulgaris Savi, both synonyms of Dolichos 



* Retained name, Vienna Code; Botor Adans. (1763) is older.
