foliage leaves. B. Ditto of same plant taken just below stem apex, showing vas- 
cular bundles of young foliage leaves in stem (Hatfield) . . . *573 
Portion of longitudinal section of stem, just below stem apex, showing the ‘ growth 
ring ’ or procambium, and cells of pith and cordex which have been formed by it 
(Hatfield) 574 
Xylem and cambium of hypocotyl, as seen in transverse section (Hatfield). . 578 
Young plant cut longitudinally nearly in the median plane, and treated with phloro- 
glucin to bring out xylem (Hatfield) 579 
Tracings of adjacent sections from a leaf of Passerina cf. falcifolia in which the 
groove was lightly closed ; left, in oil, the edges overlapping ; right, in water, 
groove open, tissues expanded (Thoday) 588 
Diagrams of sections of old healthy leaves of ( a ) P. filiformis, if) extreme shade 
plant of P. cf. falcifolia (Thoday) 589 
Part of section of leaf of P. cf. falcifolia (Thoday) 589 
Epidermis of corresponding parts of two adjacent sections : ( a ) in oil, showing 
bellows-like foldings ; ( b ) expanded in water (Thoday) . . . ' . 590 
Outer epidermal and palisade cells from microtome sections of closed leaf, fixed in 
absolute alcohol and embedded in paraffin. The contents of each epidermal 
cell (shaded) form a somewhat contracted brown gelatinous mass. Palisade cells 
with finely-folded walls (Thoday) 592 
Section through median bundle of leaf of P. filiformis, showing lateral wandering of 
fibres hypodermally. The fibres drawn near the phloem were the only ones that 
stained yellow with chlor- zinc-iodine (Thoday) 595 
Fibres of ordinary form from minor veins of young leaf of P. filiformis (Thoday) . 595 
Hypodermal wandering fibres between two veins (Thoday) 596 
a-e. Branching hypodermal fibres (Thoday) 596 
a. Ultimate vein ending freely, from shade leaf of P. cf. falcifolia. The strand of 
fibres projects like a brush beyond the vascular tissue. The club-shaped tips are 
shown on a larger scale in b. In a (left) two fibres show abortive wandering 
(Thoday) • 597 
Middle part of section of juvenile leaf of P. filiformis. Epidermis with mucilaginous 
inner walls ; a few fibres wandering longitudinally from the bundle (Thoday) . 598 
Portion of section of juvenile leaf of P. filiformis, showing sunk stomata in upper 
concave epidermis (Thoday) 598 
Dead cells from epidermis of juvenile leaf, showing swelling of mucilage and 
collapse of lumen (Thoday) 599 
Cupressinoxylon antarcticum. Radial longitudinal sections, showing field pitting 
of the medullary rays, a, Slide V. 10291. b, Slide V. 13615 d (Edwards) . 612 
C. antarcticum. Tangential longitudinal section, showing a partly biseriate ray 
with adjoining parenchyma. Slide V. 13616 c (Edwards) .... 613 
C. Hookeri, from Tasmania. Radial longitudinal section to show medullary ray 
pitting. Slide V. 332 b (Edwards) . . . . . . . .613 
Dadoxylon kerguelense. Radial longitudinal section, showing thin plates and 
projections of resin. Slide V. 5867 b (Edwards) 615
