60 The Vegetable Individual in its relation to Species. 
foliaceous-leaf formation, keeping pace with the change of sea- 
son, is seen in the creeping main-shoot of Adora, and in the 
stock of, Hepatica nobilis, creeping close to the soil, with its 
short internodes, and which in so far deserves its French name 
(la fille avant la mére) as its flowers, which unfold before the fo- — 
liage, do not belong to the same individual as the foliage, but are 
produced laterally as a “ danghter generation” from the axils 
the inferior-leaves of the maternal stem.* A. similar chenvedal 
non only in a higher degree, (a rising and falling between folia- 
ceous- aud superior-leaf formation.) is presented “by those plants 
whose inflorescence ends in a foliaceous coma, as isvemarkably 
the case in the Pise-Apple, and also in the New Holland species ( 
of Melaleuca and Callistemon, whose crowded, brush-like inflo- : 
rescence (i. e. the region covered with superior-leaves and bear- ee 
ing the flowers in the axils of these) returns and forms foliace- 
ous-leaves, and in the following year again attains an inflorescence. 
While every leaf-formation may bring the progress of the met- 
amorphosis on a single shoot to a consmmmmation, it is conceivable 
that one shoot may be allowed to each step for itself alone. Thus, 
there are shoots which represent inferior-leaf formation alone; e.g. 
the root-stock of Paris quadrifolia, the tuberiferous branches of 
the rhizoma of the Potatoe,t and there are some which are en- 
dowed with the foliaceous-leaf formation cts as the primary 
axis _ many species of Veronica, the sterile leafy branches of 
several Euphorbia, as well as theleafy jeunes of those woody 
piiuntted which have no bud-scales aud no terminal infloresc 
(e.g. Rhamnus Franguila). Cases of pure superior-leaved shoots 
may be seen in the peduncles of Veronica Chameadrys, officin 
dis, etc., in the (always lateral) spike-bearing scapes of Plantago, — 
and the racemes of Convallaria majalis, which shoot out of the 
axil of the highest lower-leaf as branches. Even the leaf-form- 
ation belonging to the flower can be divided among different
