74 LIMNANTHACEJE. (LIMNANTHES FAMILY.) 



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

 ones, which arc 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. 5. pallida, Nutt. (Pale Touch-me-not.) Flowers pah 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, pctioled, toothed. 



2. I, f&lva, Nutt. (Spotted Touch-me-not.) Flowers orange-color, 

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

 ing into a strongly inflexed 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 cornucopiae-shaped sepal upward. A variety 

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

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



I. Balsamina, L., is the Balsam or Ladies' slipper of the garden. 

 Trop^olitm majus, the familiar Nasturtium of gardens, is the type of a 

 group intermediate between the Balsam and Geranium families and the next.
