found them penetrate to the wood; *1 liave not seen its attacked 
roots. It is not very commonly found in sandal tracts. 
{120) Art near pus integri folia — (Evergreen tree). — A root of this 
species was foiind close to a sandal tree on Thirumalai Hill in Tre- 
vandrum and it l)ore traces of sandal attack ; the haustoria were 
flat, membranous and dead ; this species does not seem to be a good 
host — further observation is required. 
Casuarine.t:. 
{ISO) Casuarina equisetifolia — (Evergreen tree). — This is said 
to be a very good nurse for sandal up to a certain age. Dr. Barber 
has examined sandal haustoria on its roots. I have not seen its

might prove a very good nurse for sandal.

{132) Sansevieria zeylanica — (Evergreen shrub). — I found 2 
sandal haustoria and a scar on a root of this ; they were small ; 
whether penetration had been effected could not be ascertained. 
Dr. Barber examined sandal haustoria on its roots under the micro- 
scope and found formation of protective corky layers on the cortex 
before the haustorial sucker reached the vascular bundles, thus 
effectively cutting it off from the latter. 
Amautleide.®. 
{133) Agave Vera-Cruz — (Evergreen shrub). — Dr. Barber ex- 
amined sandal haustoria on the roots of this species and found the 
sucker cut off from the vascular bundles of the host by the formatioi]
