authors have generally considered it as a distinct species, some 

 under the name Vigna unguiculata (Linn.) Walp. However, 

 Dolichos unguiculatus Linn., the basis of Vigna unguiculata 

 Walp., is Phaseolus unguiculatus (Linn.) Piper, in Torreya 12 

 (1912) 190 (Phaseolus antillanus Urban), and has nothing to 

 do with Vigna, with which it has been confused. Linnaeus 

 cites the Rumphian name and figure in the original publication 

 of Dolichos catjang (1771), in which he was followed by Bur- 

 man f., Murray, Lamarck, Loureiro, Willdenow, Persoon, de 

 Candolle, Don, and other authors. Rumphius described two 

 forms, I albus and II ruber, which Hasskarl, Neue Schlussel 

 (1866) 135, indicated as Vigna catjang var. alba Hassk. and 

 V. catjang var. ruber Hassk., respectively. Both are probably 

 merely cultural forms of the species.

 Amboina, Hatiwe and Eri, Robinson PL Rumph. Amb. 536, September, 

 1913, along the strand, locally known as katjang laut. 



The specific name above adopted for this well-known and widely 

 distributed strand plant seems to be the oldest valid one for it. 

 Burman's species is typified by the Rumphian figure and descrip- 

 tion, the figure being an excellent representation of the plant 

 commonly called Vigna lutea A. Gray. It is one of the few 

 species published by Burman in the Index Universalis issued 

 with Volume VII (Auctuarium) of the Herbarium Amboinense.

The common yam bean is not represented in our Amboina col- 

 lections. It was introduced into Amboina from the Philippines, 

 having been brought to the latter group from Mexico by the 

 Spanish colonists. Cacara bulbosa was originally reduced by
