IMPATIENS (from the Latin; having reference to the 

 pods, which, when ripe, on slight pressure burst open, 

 scattering the seed). Geranidcece. (By some referred 

 toBalsaminacece.) Tender, succulent herbs, with 

 very fleshy stems and simple leaves usually alter- 

 nate and the upper ones often in whorls: pe- 

 duncles axillary, with 1-6 or more fls. of various 

 colors: sepals 3 (seldom 5), the posterior one 

 taking on a spur-like shape; petals 5 or 

 3, in which case 2 are grown together: 

 fr. a pod, which, when ripe, bursts when 

 pinched, scattering the seeds. About 

 220 species, mainly from tropical India 

 and Africa. About 20 have found their 

 way into cultivation for the most part 

 as greenhouse plants, 1. Balsamina being the species 

 best known as an outdoor annual. See Balsam. Propa- 

 gation by cuttings and seed. 



A. Peduncles with single fls. 



Hawkeri, W. Bull. A bushy, soft-wooded plant with 

 well branched stems of a dull red color; Ivs. opposite or 

 in whorls of 3, ovate, acuminate, serrate, dark green:
