have taken several days or weeks to collect, had the other alternative 
of digging up roots of host-plants on plains or hill slopes been 
adopted. 
9. In the description of the haustoria or their scars and the 
extent of attack on each species of hosts examined or observed by 
me, numerous repetitions occur ; but I consider it better to retain 
them rather than aim at brevity at the expense of details which may 
eventually help us in arriving at generalisations regarding the in- 
fluence exerted by a genus or a sub-family or a family as a whole 
cn sandalwood. The accompanying plates of some of the roots 
attacked showing the haustoria and their scars were prepared at the 
commencement of my investigations, but no drawings of roots 
subsequently examined were prepared as it was thought unnecessary 
and expensive to do so. 
10. The following is a brief account of the host-plants obserwed 
and examined by myself and by others : — 
I. Dicotyledons. 
Anonace.e. 
(1) Gonioihalamvs wynaadensis — (Evergreen shrub) Javadi 
Malayalees call it Palichan sedi . — The roots of this plant are pretty 
largely attacked by sandal roots whose haustoria penetrate to the 
woody cylinder. The haustoria are of medium size and pretty deep, 
but not high above the host’s surface. This shrub is not common 
in the sandal tracts, but is occasionally met with associated with 
sandal in Kambugudi and elsewhere on the Javadi hills. 
(2) Goniothalamvs sp. — (Evergreen shrub) Javadi Malayalees 
call it Kakanan sedi . — This is also attacked by sandal roots more or 
less like No. I. 
(.3) Anona sqtwiiiosa — (Semi-evergreen small tree). — Only one 
root examined ; bore superficial scars of sandal haustoria which had 
penetrated to the woody cylinder of the host ; does not seem to be 
affected to the same extent as No. 1 and probably less hospitable; 
the scars seemed to have been healed by callus growth from the 
cambium in the specimen examined.
