'23 G. JAVA'NICA (Lin. spec. 1024.) stem twining, beset with 

 retrograde villi as well as the petioles ; peduncles length of 

 leaves ; flowers disposed in dense spikes, nodding ; bracteas 

 lanceolate, minute. Native of the East Indies and Japan. 

 Thunb. in Lin. trans, vol. 2. p. 340. Flowers violaceous. The 

 plant under this name in the herbarium of Retzius has 3-lobed 

 repand leaflets, the middle lobe acute, the lateral ones short and 

 very blunt ; the peduncles are also longer than the leaves, and 

 the flowers are disposed in rather loose spikes, also the calyx is 

 acutely 5-toothed. It is, however, only the same species.

 spiny bristles). D. C. Leg. mem. vi. prod. 2. p. 243. 



LIN. SYST. Diadetphia, Decandria. Calyx beset with glands

SECT. II. KUHNISTE'RA (in honour of Adam Kuhn, a pupil of 

 Linnaeus. There is, however, a genus Kuhnia, named by Lin- 

 neus in compliment to him ; the different termination of the word 

 is to distinguish it from that genus). Lam. diet. 3. p. 370. Vent,

 proper genus.
