one fomponnrl haiTstoriiim on one of the roots. Dr. Barber fonncl 
no successful penetration of the haustorium into the vascular system 
of tlie root in his examination under the microscope. It is doubt- 
fill whether this species is of any service to the sandal as a nurse. 
11. The species of plants described above are not the only ones 
which are associated with sandal. They merely represent those 
whose roots have been examined hitherto and found to be attacked 
by sandal roots. Numerous other species of plants are found 
associated with it in its natural habitat and their roots still await 
examination in order to ascertain whether and, if so, to what extent 
sandal attacks and forms root-connections with them. A list of such 
plants — taken from the appendices to Dr. Barber’s “Studies in 
Boot-parasitism — The Haustorium of Santaliim album,” Volume I, 
No. I, Part II, of the Memoirs of the Department of Agriculture 
in India, and from my “ Tirupattur Sandalwood Working Plan” 
published in the Proceedings of the Board of Eevenue, Madras, 
Forest No. 172, dated 20th August 1904, and from other sources — 
is appended to this note. It is believed that this list is not ex- 
haustive and that there are many other associates of sandal which 
have to be ascertained by inspections of the sandal tracts in the 
various parts of India where it occurs. 
12. Ml. A. W. Lushington, Conservator of Forests in the Madras 
Presidency, is of opinion that evergreen plants are probably better 
hosts of sandal and that investigations in this direction will prove 
very useful. Judging from the fact that 82 out of the 144 species 
of host plants already examined and described above are evergreen 
or nearly so, I am inclined to agree with him. This point deserves 
to be studied further. 
He also suggests for investigation the question whether essential 
oil-bearing or balsam-producing species have any special effect 
upon the sandal, and, if so, to what extent. He writes to me that, 
in May 1908, he observed in Bamiindriig in the Bellary District 
sandal plants growing on or near evergreen species remained ever- 
green while tho,se growing on deciduous species became deciduous 
and were just putting forward new young leaves after losing all 
their old leaves. I have also observed a tendency in the sandal 
to become deciduous in very dry localities in the Mysore Province, 
Salem and Kurnool Districts, especially where other species of 
plants associated with it are few and are deciduous.
