a nurse as the other two Albizzias described above, but it is a 
useful associate. 
(•5<S) Fithecolohiuia dulce — (Evergreen tree). — Sandalwood is 
found to grow very well when associated with this species. I found 
two trees supporting six sandal trees in the Denkanikotta Forest 
Uftice compound without the aid of any other species and all the 
six trees were vigorous and healthy. It is largely attacked, even 
big roots not being spared ; the haustoria in the specimens 
examined were of medium size, hard and high, and the scars deep, 
exposing the inner wood of the host to view. Being a quick grower 
and useful as firewood, it is desirable to introduce it into sandal 
tracts where good indigenous nurses are wanting. 
{59) Pitliecolohium Saman — (Semi-evergreen tree). — I have not 
seen ati'ected roots of this species, but Dr. Barber has examined 
sandal haustoria on them and found them penetrating to the woody 
cylinder of the host. It may be a good nurse for sandal, judging 
from the extent of its attack on allied species. Its affected roots 
require further examination in the field. 
(60) Kattu-tainatai (Tamil) — (Deciduous climber). — This is a 
comparatively stout leguminous climber with pink flowers and large 
pods. I found its roots most largely attacked by sandal roots ; the 
haustorial scars were large and deep, in some cases burrowing into 
the wood of the host ; some of the scars were covered over by callus 
wood and the roots examined were almost completely covered witli 
scars. This is an excellent host for sandal and grows commonly at 
elevations above 2,500 feet. 
{61) A leguminous climber — (Deciduous). — With pink flowers 
resembling Dolicbos Lablub but much stouter; was found very 
largely attacked and bore haustorial scars and haustoria whicli were 
quite conical, woody and high in some cases and flat and membran- 
ous in others ; penetration had been effected as the scars were deep 
and exposed the inner wood to view. This was found at Salem 
950 feet above sea-level associated with sandal in a garden hedge. 
{62) Cassia aariculata — (Evergreen shrub). — This is said to be 
very largely attacked and Dr. Barber has examined sandal haus- 
toria on its roots. I have not seen its affected roots. For young 
sandal it is considered an excellent nurse. 
{63) Cassia siamea — (Semi-evergreen tree). — This is extensively 
attacked in some localities and sandal grows very well in its com-
