the larger ones, as described above, which seldom ripen seeds, and very small 

 ones, which are fertilized early in the bud, when the floral envelopes never ex- 

 pand, nor grow to their full size, but are forced off by the growing pod and car 

 ried upwards on its apex. (Name from the sudden bursting of the pods when 

 touched, whence also the popular appellation, Touch-me-not, or Snap-weed.) 



1. I. pSillida, Nutt. (PALE TOUCH-ME-NOT.) Flowers pale yellow, spar- 

 ingly dotted with brownish-red ; sac dilated and very obtuse, broader than long, 

 tipped with a short incurved spur. Moist shady places and along rills, in rich 

 soil; most common northwestward. July Sept. Larger and greener than 

 the next, with larger flowers. Leaves ovate, petioled, toothed. 



2. I. fiilva, Nmt. (SPOTTED TOUCH-ME-NOT.) Flowers orange-color, 

 thickly spotted with reddish-brown ; sac longer than broad, acutely conical, taper- 

 ing into a strongly itiflexed spur. Rills and shady moist places ; common, 

 especially southward. June -Sept. Plant 2 -4 high: the flowers loosely 

 panicled at the ends of the branches, hanging gracefully on their slender nod- 

 ding stalks, the open mouth of the cornucopias-shaped sepal upward. A variety 

 is occasionally found with spotless flowers, which differs from the I. Noli-tangere 

 of Europe chiefly in the more inflexed spur and smaller petals. 



I. BALSAMINA, L., is the BALSAM or Ladies' slipper of the garden. 

 TROP.SOLUM MAJUS, the familiar NASTURTIUM of gardens, is the type of a
