Fig. 14. Side view of the blade of the leaf in fig. 8. 
Fig. 15. Base of a petiole and bunch of young roots, natural size, side view. 
Fig. 16. The same, seen from above. 
Fig. 17. Perpendicular section through the base of a petiole, as in fig. 15 ; showing the 
course of the vascular bundles of the leaves {vl) and those of the roots {vr). 
Fig. 18. A seed, natural size. 
Fig. 19. Vertical section of a seed, showing the embryo [e) lodged in an excavation of 
the perisperm. 
Fig. 20. Embryo (magnified) removed from the seed, but still enclosed in its amniotic 
sac : — «, from below ; J, side view ; c, vertical section, showing the amniotic 
coat and the cotyledons, with the plumule in the middle. The figure ns 
indicates the natural size of a. 
Fig. 21. Embryo (magnified) with the amniotic coat removed, showing the distinctly 
Dicotyledonous structure : — side view ; h, from above ; c, from below, with 
the central boss-like radicle ; d, cotyledons separated to show the plumule ; 
e, one cotyledon only turned down ; /, plumule laid bare in side view. 
Fig. 22. Germinating plant, with the petioles, of the leaves 3, 4, 5, 6 : 2 is the scar of 
the removed second leaf, with a minute scale-like axillary stipule remaining ; 
the remains of the first leaf would appear on the other side of the stem. 
Fig. 23. The seed, with the base of the germinating plant emerging from it : — r, radicle ; 
t, stem {tigelle) ; nat. size. 
Fig. 24. Front (A) and back (B) view of the base of the germinating plant, magnified : 
— p?, the portion contained within the coats of the seed in fig. 23, and appa- 
rently corresponding to/’in fig. 21. 
Fig. 25. Another and more enlarged view of the same structure : — r, radicle ; o, oper- 
culum ; pi, primordial leaf; 1 1, first internode ; si, second (rudimentary) leaf; 
t 2, second internode. 
PLATE XXX. 
Fig. 26. Perpendicular section of the young stem represented by fig. 22 ; showing the 
pseudo-Monocotyledonous arrangement of the vascular bundles, except in the 
rootlets r r, where they occupy the absolute axis. 
Fig. 27. Punctum vegetationis of the rhizome, highly magnified ; — I, a rudimentary leaf 
turned back, showing the relative development of the blade h, and the stipu- 
lary portions s, s, — the petiole not yet developed ; f, rudimentary flower-bud. 
Fig. 28. The flower-bud / in fig. 27. 
Fig. 29. Diagram of the arrangement of the four sepals and first petal, showing it to be 
a continuous spiral. 
Fig. 30. Magnified perpendicular section of a flower-bud rather older. In this and the 
following figure the sketches marked ns indicate the natural size.
