Fig. 848. Ine White Wintergreen (Ckdogenes) ; it has a procumbent stem 
above the ground at all, but only sending up leaves and 
flowers with their stalks, as the Tulip. 
226. It is the nature of the stem to produce buds, as it is of © 
the root to produce none. At first the stem is itself a bud, 
and as it grows it bears this bud always at the summit and 
produces a new bud in the axil of every new leaf. 
Fig. 344. Poor-man’s-weather-glass (Anagallis) ; it has a decumbent stem. 
227. The stem has nodes and internodes. The joints where 
the leaves severally come out are the nodes, and the portion 
of stem between, the internodes. In the bud the internodes 
are quite undeveloped, and the nodes close together; but as 
it develops into a regular leaf-stem, the internodes grow, and 
the nodes with their respective leaves are separated. 
228. But in some plants, the nodes only are developed, and 
the axis never extends itself above ground, and covers itself 
225. What of the stem of Tulip? 
226. What the nature of the stem with respect to buds? 
227. Please tell us what are nodes and internodes.
