Anacardiace^. 
(•37) Manffifern indicn — (Evergreen tree). — I foiind the roots of 
this species largely attacked by sandal roots and the scars of haus- 
toria on them pretty large, being in some cases ^ inch long and 
inch broad ; in a few cases the wood of the host had been pene- 
trated. In some places I found sandal growing vigorously near the 
mango, while, in others, it was sickly and yellow-leaved. Its value 
as a host has to be determined by further observations. From 
observations in various places I am led to suspect that the sandal 
would avoid this species if it has more congenial hosts to live upon, 
possibly owing to the acrid juice of this plant. 
(•38) Anacardivm occidentale — (Semi-evergreen tree). — Mr. A. 
W. Lushington, Conservator of Forests, has found sandal seedlings 
establishing root-attachments with this species in the forest garden 
at Waltair. I have not met with its affected roots in the natural 
sandal areas I have seen, but in a garden at Quilon I found its 
roots attacked and a few haustoria formed on them. 
Leguminos.®. 
(39) Clitona sp . — (Deciduous twiner). — A young plant of this 
species bore four small sandal haustoria on its roots; the haustoria 
were woody and hard ; seemed to have penetrated to the woody 
cylinder of the host ; in some sandal tracts this is often met with. 
(dO) Dolichos Lallah (Sittavdrai in Tamil) — (Deciduous 
twiner). — The succulent and tuberous tap-root and rootlets of this 
species were attacked by sandal in two different plants. The living 
hau.storia on one were much larger than in the other; this plant 
seems to be a good host for young sandal. 
(41) Dalhergia Sissoo — (Evergreen tree). — The roots of a sissoo 
tree were very extensively attacked by the sandal roots in the 
Denkanikotta Forest Office compound. The haustoria were com- 
paratively large, hard and prominently high; the scars were deep, 
exposing the wood of the host to view. Though an exotic to sandal 
tracts, it woiild probably form a very good nurse wherever it could 
be grown with sandal. Being a timber tree its introduction into 
.sandal areas would be doubly profitable. Plate III illustrates a 
root collected by me.
