produce no lamina, are still similar in character to those of 
the normal shoot. 
(b) The inflorescences, when present, are produced on these 
flagella as axillary buds (cf. Die naturlichen Pflanzenfamilien, 
II Teil, 3 Abteilung, p. 16, Fig. 14, L). 
( c ) The displacement is sometimes only comparatively slight, 
whereas in most cases the flagella are inserted near the upper 
limit of the sheath. Examples are occasionally to be found 
(especially in young shoots) where the flagellum is almost 
exactly in the normal position in the axil of the lower leaf. 
(d) In those shoots in which the displacement is greatest, 
an examination of the apical bud shows that the original 
position of the flagellum is axillary, and that the displacement 
is due to irregularities of secondary growth. If thick transverse 
sections be cut from such 
a bud (Fig. 2), the suc- 
cessive leaves may be seen 
as complete circles of al- 
most uniform thickness all 
round : axillary buds are 
not always formed in their 
axils, but in those cases 
where they are present, 
the midrib of the leaf 
(marked x in Fig. 2) is 
usually seen to be the 
thinnest part ; opposite it 
is to be seen the axillary 
bud, which may be re- 
cognised as being ad- 
herent, even in very early 
stages of development, to 
In longitudinal sections 
through an apical bud (Fig. 3), when the next lower leaf 
is cut in a median plane, the base of its sheath is seen to 
be very thin, while opposite it is the axillary bud, which may 
be seen even in a very early state to be adherent to the next
