You will observe the same general structure of flower 

 in the Monarda (sometimes called Mountain Balm), 

 but none of this peculiarity in the structure of the 

 stamens ; the corolla, also, is very long and narrow, so

 with a species of Sage (S. lyrata) having transversely 

 divided or lyrate leaves, without wrinkles, and almost 

 without odor.

Of the Grasses. 



Under this botanical title, or Gramine;e, are also 

 included all the grain we cultivate, in common, as 

 well as Grass, Reeds, and the Sugar-cane. This tribe, 

 almost without exception, have three stamens, and 

 two styles, though but a single seed in a husk. No 

 person, who has ever seen a field of Maize (here 

 called Corn), at the time when it begins to show a 

 promise of the grain, need be at a loss, on examining 

 the top or panicle of this plant, for the obvious exist- 

 ence of stamens, and every three of them will be 

 found separately included within a small husk of two
