Hig. 1. An attack of Cansjera upon a root of Capparis horrida. A portion 
Fig. 2. The 
of the sucker and the end of one of the host’s cortical wings 
are shown. The cells of the wing are completely isolated from 
the rest of the host’s tissues by a thick layer of cork (ck), and 
yet they are crammed with starch while the rest of the 
root has little or none. In la the tissues are further magni- 
fied. The cells at the side of the sucker (xz) are cut off by a 
collapsed layer and are filled with minute'y granular starch 
(the original contents apparently suffering fragmentation). 
The cells of the wing are dead and browned but filled with 
clear and large starch grains. 
sucker of a haustorium imbedded ina root of Capparis 
horrida, The parts within the dotted lines are full of 
starch (st) and this substance is absent from the rest of the 
section. Starch, it will be seen, is only deposited where the 
layer of secretion is formed, that is, presumably, where the 
passage of fluids has ceased. The remains of a former 
gland (g/) are seen. 
Fig. 8. A haustorium of Cansjera Rheedii penetrating another Cansjera 
root. The haustorium which, in many respects, is typical, 
has fused in various places (/) with the host’s tissues. Note 
the bundle from the mother root (m.r.) with its bast and 
endodermis (e). These are absent in the haustorium, but a 
thick layer of cambiform tissue (c) is met with. The distribu- 
tion of the masses of calcium carbonate crystals (er) in host 
and haustorium is instructive. Broad bands of cork are 
formed where the cortical folds are in contact with the host’s 
bark, the discoloured portions being old cork (ck) and the 
white lines young cork and phellogen (ph).
