passes through and bears ov. some abortive ovaries, and at its 
summit another flower f£. which is seen cut in f. 14. in which the 
petals and sepals are removed: s. s. the sepals of the second 
imperfect flower, containing p. the petals, stamens, and ovaries. 
Pl. 20 f. 1. Flower of the Alpine Strawberry, in which all the 
parts are changed into leaves; p. the petals: f. 2. a petal removed, 
showing its lobed form, and fringed edge ; (compare this with a 
petal in f. 6.): £. 3, two stamens changed into leaves, but retaining 
traces of the anther, a. f. 4. a carpel c. changed into a leaf, 
containing o. an ovule, changed into a leaf: f. 5. the same parts 
cut open: f. 6, p. the petals of the Strawberry seen to be alternate 
with the sepals s. which in f. 7. s. s. alternate with the bracts 6. 
f. 8. a plan of the flower of Flax; in which s. s, represent 
the five sepals; placed within and alternate are five petals p. p. 
within which, are five stamens st. alternate with the petals; 
and five carpels ¢. each containing two ovules, alternate with 
the stamens: f. 9. stamens of the Geranium; sc. the scales or 
rudimentary stamens: f. 10. a plan of the Geranium flower ; 
s. s. the five sepals; p. p. five petals alternating ;_sc. five scales 
or rudimentary stamens alternate with the petals; then come 
five outer stamens alternate with the scales, and five inner 
alternate with the five outer stamens which also are shorter; and 
five ovaries alternate with the five inner stamens: in this figure 
six sets or whorls of floral organs are seen arranged alternate to 
euch other: f. 11. flower of the Rue; st. five outer stamens; 2. 
the nectary or rudimentary set of stamens: f. 12. is a plan of 
the same flower; s.s. the sepals alternate with the petals p. the 
stamens are in two rows of five each; the inner row opposite to 
the ovaries, between which and the stamens exists the ring n. 
seen in f. 11. the nectary, or rudimentary set of stamens which if 
produced would make the alternate arrangement of all the parts 
of the flower complete: f. 13. an ideal arrangement of all the 
parts of the flower in alternate succession; 1/1. the leaves; s. s. 
the sepals, alternate with p, the petals; st. the stamens alternate
