Part IV.] Rama Rao ; Host Plants of the Sandal Tree, 
these two species have not been examined by me, but Dr. Barber^ 
has examined the sandal haustoria formed on them ; how far these 
species are attacked by the sandal and whether they serve as good 
associates require further investigation.

{6) Tinospora cordifolia — (Deciduous climber). — The roots of a 
small plant were found attacked and two living haustoria and four 
scars of withered ones were found ; the haustoria were of moderate 
size and had penetrated the woody cyliiuler. This species appears 
to be a moderately good nurse to sandalwood in its early stage of 
growth.

{7) Capparis zeylanica — (Deciduous shrul)j. — I examined a few 
roots and found living sandal haustoria and scars of withered ones 
on them. The haustoria were of medium size, broad and flat-based 
and pretty high above the surface of the host. Examination under 
the microscope showed penetration with sucker lobes surrounding the 
woody cylinder of the host over more than half the length of its 
circumference ; this species appears to be pretty largely affected and 
may be a good nurse in dry localities where it is commonly found. 
Malvace.33. 
(5) Thespesia populnea — (Evergreen tree). — The roots and root- 
lets of this plant are very largely attacked and the haustoria are 
somewhat larger than those fpund on the species already described 
above. The roots being full of warts, not infrequently the haustoria 
are formed on them ; microscopic examination shows complete 
penetration, the sucker-lobe extending sometimes to the centre of 
the woody cylinder ; the scars are deep and expose the wood of the 
host to view. 
This species seems to form an excellent nurse for sandal, though 
an exotic to the natural habitat of sandal ; it reproduces itself 
readily from cuttings, thus rendering its propagation easy and
