haustorial scars and one living liaustorium which was a little larger 
than of medium size. The scars showed penetration of the haus- 
toria into the woody cylinder. This seems to be a good nurse for 
sandal and is commonly associated with it, especially in dry scrub 
jungles. 
{92) M'rightia tinctoria — (Deciduous tree). — The tap-root and 
side-roots of a small tree were covered with a large number of haus- 
torial scars and only two living haustoria ; a few of the scars were 
large and showed up the inner wood of the host to view ; this species 
seems to be very extensively attacked and must therefore be a very 
good host. Being common in dry scrub forests, it will he a useful 
nurse for sandal. 
AsCLEriAUACE-i; . 
{93) Drege.a colubilis — (Deciduous climber j. — The roots of this 
plant are very extensively attacked. As the roots are thick-barked 
and soft wooded, the sandal haustoria penetrate to the wood and 
disorganise the tissues of the host ; the haustoria are very large and 
woody and the scars large and deep. Being a stout climber, it 
appears to be a very good nurse for sandal although otherwise of 
little economic value. 
{94) Heterosiemmu sp. (Karalankodi, Tam.) — (Deciduous). — An 
Asclepiadaceous plant resembling Heviidesmus. This is moderately 
attacked and the haustoria and scars are of medium size ; they pene- 
trate to the wood. It occurs commonly in sandal areas. 
{96) Sarcosternma brevistigina — (Evergreen climber). — I have 
not seen attacked roots of this plant, but Dr. Barber has examined 
sandal haustoria on its roots. Its attacked roots require further 
examination to ascertain to what extent it serves as a nurse for 
sandal. 
Bor.agine.e. 
(•96') Cordia Mgxa — (Deciduous tree). — Dr. Barber has examined 
sandal haustoria on its roots and found them penetrating to the 
woody cylinder. I have not seen its attacked roots. Its value as a 
nurse has to be ascertained by further examination in the field. 
(.97) Ehretia hevis — (Deciduous tree). — I have seen small roots 
of this species attacked by sandal roots ; the haustoria on them were
