34 THE PHENOMENON OF 



the number of the co-ordinate sprouts of each rank, the 

 region and the abundance in which the said formations 

 occur on the various axes, the relative dimensions of 

 these axes, &c. A few examples placed side by side for 

 the sake of comparison, may render these further dis- 

 tinctions more clear. 



Paris quadrifolia and Lysimaclda Nummularia, both 

 have a two-membered chain of sprouts ; but the endow- 

 ment of the two axes is quite different. In Paris, i is a 

 cataphyllary sprout creeping underground ; ii, brings forth 

 successively a basilar cataphyllary formation, the euphyl- 

 lary formation, and the flower. In Lysimaclda Nummu- 

 laria, i is a creeping euphyllary sprout ; ii, immediately 

 produces the flower. 



Convallaria majalis and Convallaria muliijlora have 

 both three-membered series of sprouts, both also have the 

 same distribution of the formations, namely, on axis i, 

 the cataphyllary and euphyllary formation ; on ii, the 

 hypsophyllary formation ; while iii concludes with the 

 flower. But they are distinguished in the relations of the 

 emergence of the shoots ; in Convallaria majalis, ii, arises 

 from the cataphyllary region of i ; in Convallaria multi- 

 flora from the euphyllary region. They differ, moreover, in 

 reference to the number of the co-ordinate sprouts, since 

 Convallaria majalis possesses only a single sprout of the 

 second generation, thus only one inflorescence; Convallaria 

 multiflora numerous inflorescences, but less numerous 

 sprouts of the third generation, i. e. only a few flowers in 

 each inflorescence. Cyclamen and Centunculus both have 

 two-membered series of sprouts, both the same distribution 

 of the formations and the same regions of origin of the 

 sprouts : i, being a euphyllary sprout ; ii, blossoms from 

 the axils of the euphyllary leaves. Here the relative 

 dimensions are the principal causes of the very different 

 habit. In Cyclamen, i is a tuberous stock; ii, the 

 blossom, on the other hand, has an elongated stalk ; in 

 Centunculus, on the contrary, i is a delicate little sprout, 

 while the flower is almost sessile.
