vigorous and attaining a greater height (10-12 ft.); in the somewhat 

 brighter orange color of its fruits; and especially in the harsher, more 

 biting flavor of the peel, which evidently contains an etherial oil more 

 nearly resembling that of the common orange than does that of the 

 round kumquat.

^ The original publication of this species by citation is on p. 199 as follows: 

 "Kin Kan, vulgo Fime Tats 



banna, p. 801. , Citrus laponica." 



Under the heading Characters of New Species it is given as follows, on p. 208: 

 'Citrus japonica: petiolis alatis, foliis 



acutis; caule fruticoso." 

 The species is published by the citation on page 199, inasmuch as Kaempfer 

 identifies the plant not only by giving the Chinese characters never applied to 

 any other plant but also the Japanese common name and a short latin phrase 

 sufficient to distinguish it from any other Citrus.
