4. IMPATIENS, L. Balsam. Jewel-weed. 



Calyx and corolla colored alike and not clearly distinguishable. Sepals ap- 

 parently only 4 ; the anterior one, which is notched at the apex, probably con- 

 sisting of two combined ; the posterior one (appearing anterior as the flower 

 hangs on its stalk) largest, and forming a spurred sac. Petals 2, unequal-sided 

 and 2-lobed (each consisting of a pair united). Stamens .5, short : filaments 

 appendagcd with a scale on the inner side, the .'5 scales connivent and united 

 over the stigma : anthers opening on the inner face. Ovary 5-cellcd : stigma 

 sessile. Pod with evanescent partitions, and a thick axis bearing the several 

 anatropous seeds, 5-valved, the valves coiling elastically and i)rojecting the 

 seeds in bursting. Embryo straight : albumen none. — Leaves simple, alter- 

 nate, without stipules, in our species ovate or oval, coarsely toothed, petioled. 

 Flowers axillary or panicled, often of two sorts, viz., — the larger ones, as 

 described above, which seldom ripen seeds; — and very small ones, which are 

 fertilized early in the bud ; their floral envelopes never expand, nor grow to 

 their full size, but are forced off by the growing pod and carried upwards on 

 its apex. (Name from the sudden bursting of the pods when touched, whence 

 also the popular appellation, Tonch-mc-not, or Snap-weed.)
