the natural habitat of sandal, it does not seem to be so largely 
affected as other species of the same family ; in the roots examined 
by me there were a number of small-sized scars of withered haus- 
toria exposing the wood of the host. I have found sandal trees 
growing vigorously in its company in some places, while in others 
they were stunted and yellow-leaved. Perhaps its dense shade and 
acidity of its sap do not quite suit the taste of the sandal. 
{48) Adenanthera lyavonina — (Deciduous tree). — Dr. Barber has 
examined sandal haustoria on this species and found them penetrat- 
ing the woody tissues of the host and breaking them up. I have 
not seen its roots attacked. It is likely to be a good nurse. 
{49) Parkia biglandvlosa — (Deciduous tree). — Dr. Barber has 
examined sandal haustoria on its roots and found them penetrating 
the woody cylinder of the host. I have not seen its attacked roots ; 
whether this species is a good nurse or not requires to be investi- 
gated in the field. 
{oO) Leucccna glauca — (Evergreen shrub or small tree). — Dr. 
Barber mentions this as one of the species the sandal haustoria on 
whose roots were examined by him. Not having seen its affected 
roots, I cannot say anything about its value as a host-plant. It 
requires further investigation. 
(51) Acacia pennata — (Evergreen climber). — This is very 
largely attacked and young sandal trees thrive very vigorously in 
its company. The haustoria and scars are pretty large and the 
former lignified and hard ; they penetrate to the woody cylinder. 
I liave no doubt that this is an excellent nurse for sandal and is 
commonly found in sandal tracts. 
{52) Acacia Intsia (crcsia) — (Semi-evergreen climber). — This is 
also very extensively affected, more so than .4. pennata. The haus- 
toria and scars are about the same size as in the latter and equally 
hard and penetrate to tlie woody cylinder of the host; a root, 22 
feet long, bore haustoria and scars throughout its whole length ; the 
haustoria were prominently high. Plate IV is the drawing of a 
root collected by me. This is an excellent nurse for sandal and is 
very common in all sandal tracts. 
{5.3) Acacia concinna — (Semi-evergreen climber). — I have not 
examined its affected roots, but Dr. Barber has examined sandal 
haustoria on them and found tliem penetrate to the woody tissues 
of the host ; it appears to be a common associate of sandal round
