IV. On the Formation of the Calyz. | f r 
E ‘This transformation often takes place rapidly ; the stem at once 
becomes tapering and delicately-formed, and shoots upwards from the 
node at which the last perfect leaf was developed, terminating in a 
whorl of leaves collected round an axis. 
92. It appears to us a fact capable of the clearest proof, that ite 
brc of the calyx are the same organs as those whose formation-we 
have hitherto been observing as stem-leaves, though now viru 
very altered condition, and collected round a common centre. aj 
.83. We have already observed in the cotyledons a similar option 
and have seen a number of leaves, and thus obviously a number of 
approximated nodes, collected round a central point. The cotyledons 
of the Pine are a rayed circle of. needle- shaped leaves with a definite 
form ; even in the earliest infancy of those plants that vigour of con- 
stitution i is, as it were, indicated, by which, at a more advanced age 
the blossoms and fruit are to be produced.* 
34. We further see, in many flowers, unaltered stem-leaves cilectad 
together so as to form a kind of calyx immediately below the inflores- 
cence. That they are stem-leaves we need only appeal to the normal 
appearance still retained, and to botanical terminology, wipes Hime 
nates them by the namé of Folia floralia (bracts). 
35. We must now observe the case in which the transition. es the 
flowering-period proceeds slowly; the stem-leaves gradually d 
in size, become altered in appearance, and gently insinuate:
