 Petals of tho water-lily (Nymphaia) gradually passing into (240) stamens. 



aro exactly in point. The leaves of the pajony, large and much divided below, 

 become smaller and more simplo above, gradually passing into bracts and thenco 

 into sepals. In Calycanthus the sepal passes into the petal by gradations so gentlo 

 that we can not mark tho limit between them. In the lilies these two organs aro 

 almost identical. In the water-lily, where the sepal, petal, and stamen aro all thus 

 graduated, the transition from petal to stamen is particularly instructive. These 

 two forms meet halfway by a perfect series of gradations, when a narrowed petal 

 is capped slightly with tho semblance of an anther. And finally, cases of a close 

 resemblance between stamen and pistil, so unlike in tho poppy, are not wanting, as 

 in the tulip-tree.

 flower-buds often exhibits the several kinds of organs much less diverse than they 

 subsequently become. See tho earbj bud of columbine Those flowers which are
