STRUCTURE OF BAMBOO LEAVES. 0] 
. Dendrocalamus giganteus, Hort. Kew. x 75. Transverse section of a very young leaf rolled 
up in bud. Longitudinal furrows, where afterwards the bulliform cells will appear. 
D. giganteus, Hort. Kew. x 325. Longitudinal section through the apparent cavity and 
transverse vein of a young leaf. "The flat thin-walled cells turgescent. 
. D. striclus, Nees. x 320. Transverse section through midrib. Groups of large thin-walled 
cells on both sides of midrib, Hairs on upper and lower epidermis. 
. D. Hamiitonii, Nees et Arn. x 75. Transverse section through midrib. Groups of large thin- 
walled cells. Vascular bundles numerous. 
PLATE 18, 
. Cephalostachyum pallidum, Munro. x 75. A surface view of the leaf, mounted in phenol, 
with three longitudinal nerves and four bands of bulliform cells, all filled with silica. Long 
and short epidermis-cells filled with silica are conspicuous. Transverse veins faintly 
visible. 
. Cephalostachyum capitatum, Munro. x 325. Upper epidermis with some bulliform and some 
long epidermis-cells filled with silica. 
. Dinochloa adamanica, Kurz. x 820. Transverse section. Vascular bundle with parenchyma 
and mestome-sheath, bands of bulliform cells in upper epidermis. Short epidermis-cells filled 
with silica in upper and lower epidermis. 
D. andamanica, Kurz. x 320. Longitudinal section, passing through the flat thin-walled 
cells which fill up the apparent cavities ; walls collapsed. 
. D. andamanica, Kurz. x 320. Longitudinal section, passing through the band of bulliform 
cells. 
Melocanna bambusoides, Trin. x 60. Surface view of leaf near inner edge mounted in glycerinc. 
One stout and four slender nerves. Broad colourless band on the edge, closely set with 
fine hairs, Transverse veins faintly visible where they cross the band of bulliform cells 
(pellucid glands, Gamble). 
. M. bambusoides, Trin. x 110. Surface view of leaf mounted in phenol. Four nerves joined 
by distinct transverse veins. Three bands of bulliform cells, half of them filled with silica. 
A number of linear epidermis-cells filled with silica. The flat thin-walled cells filling cavities 
visible as transverse lines. » 
. M. bambusoides, Trin. x 325. Lower epidermis. Over the nerve the short cells large and 
in pairs, over chlorophyll parenchyma alternating bands with and without stomata. Hairs 
of two kinds on the band without stomata. The protuberances on the outer wall of the 
epidermis-cells visible as cireles. : 
. M. bambusoides, Trin. x 110. Transverse section of a mature leaf. One stout and three 
slender nerves, three bands of bulliform cells alternating with them, girders of scleren- 
chymatous fibres conspicuous. The intermediate cell, which generally separates the two 
apparent cavities, is wanting on the left hand of the figure. 
. M. bambusoides, Trin. x 325. Transverse section of full-grown leaf. One of the bulliform 
cells between two vascular bundles filled with silica. Folds in the cells above apparent 
cavities from the lower edge only. ;
