RUMPHIUS'S HERBARIUM AMBOINENSE 



to interpret the Rumphian figures and descriptions must be 

 unsatisfactory. Linnaeus, in Stickman Herb. Amb. (1754) 9, 

 Amoen. Acad. 4 (1759) 121, reduced most of the forms that 

 Rumphius figured to Citrus medica Linn, and Citrus aurantium 

 Linn., which disposition of them is not at all satisfactory; yet 

 succeeding attempts to interpret them are hardly more satis- 

 factory. It is probable that all or most of them have been de- 

 scribed by succeeding authors, but from descriptions alone it 

 is quite impossible to determine precisely to what forms or 

 species the Rumphian plants should be reduced.

This is the common lime. Limonellus was erroneously re- 

 duced by Linnaeus, in Stickman Herb. Amb. (1754) 9, Amoen. 

 Acad. 4 (1759) 121, to Citrus aurantium Linn. Both Houttuyn 

 and Christmann cite the Rumphian figure, and Christmann's 

 specific name is the oldest valid one for the species, as shown 

 by Swingle. Blume cites the Rumphian plant as a synonym of 

 Citrus javanica Blume, Bijdr. (1825) 140, while Hasskarl, Neue 

 Schlussel (1866) 32, places it under Citrus limonellus Hassk., 

 the specific name being apparently taken from Rumphius. The 

 form figured on the same plate by Rumphius, fig. A> Hasskarl, 

 1. c, considers as a variety, calling it Citrus limonellus var. 

 oxycarpus Hassk.

The common pomelo is commonly known as Citrus decumana

 which is here accepted. Aurantium maximum Burm., a name
