9 —spathe (bud) (1 x 1). 
9 —flower in anthesis (1 x 1). 
9 —flower ; the spathe-leaves cut away, co = corolla : 
ca= calyx ; st == stigma (1 X 1). 
The stigma-apparatus (2 x 1). 
Stigma-lobes with tannin cells (outside) (15 x 1). 
Embryo-sac with a young embryo, s = suspensor-cell 
(225 X 1). 
Embryo-sac with antipodals (ant.) (225 X 1). 
Fruit, nearly ripe (1 X 1). 
Fruit, opened, with seeds (1 x 1). 
Embryo at the opening of the fruit, in side-view, p — 
plumule (1 X 1). 
Cap-like testa, loosening from the embryo at the opening 
of the fruit (1 x 1). 
Embryo at the opening of the fruit, front-view (1 X 1). 
Embryo, six days after the opening of the fruit (1 x 1). 
Seed in longitudinal section, p = plumule ; r = radicle 
(20 X 1). 
Pollen-grain (250 x 1). 
Transverse section through a placenta with mucilage and 
starch-filled outer-cells, m = mucilage ; st = starch 
(450 X 1). 
Pl. XXIV., B. 
Cross-section of a pedicel of the male inflorescence. The 
section is bisymmetrical (12*5 X 1). 
Cross-section of a female pedicel before the pollination. 
The section shows a tendency to be monosymmetrical : 
the air chambers around one of the two longer vascular 
bundles are greater than around the other one. The 
walls of the mechanical cells not yet thickened (18 X 1). 
Cross-section of a female pedicel after the pollination. 
The section is monosymmetrical. The walls of the 
mechanical cells are strongly thickened but not lignified. 
They consist of cellulose (18 x 1).
