Pakt IV. J Rama Rao : Host Plants of the Sandal Tree. 
Tlieir examination under the microscope showed no penetration into 
the vascular system of the host although numerous haustoria on 
well-developed roots were examined, I was not able to secure them 
on tender and unlignified rootlets; further examination of such 
roots and rootlets is necessary. 
Cypeeace.®. 
(139) Cyferus rotvndus — (Evergreen). — Dr. Barber found roots 
of this species attacked and examined sandal haustoria on their 
roots. I have not seen affected roots of it. 
Geamine^. 
(740) Cynodon dactylon — (Evergreen). — I found its root 
attacked by a tiny thread like sandal rootlet and two minute haus- 
toria formed. This grass may help in nourishing young sandal 
seedlings. 
(141) Elensine ccgyptiaca (indica) — Evergreen). — Young sandal 
seedlings form root-attachments with this grass and their haustoria 
are minute. 
(142) Bamhusa arundinacea — (Deciduous). — Sandal forms 
numerous root-attachments with this species and thrives very well 
in its vicinity. I have found this at Bangalore and in the Salem 
sandal areas. The haustoria are of medium size or smaller, hard 
and woody unlike those on palm roots and in the majority of cases 
compound. Haustoria on young roots were found to have pene- 
trated the vascular system, while those on older and bigger roots 
had not pierced through the sclerotic ring; in one case there were 
12 attempts made by one haustorium to effect penetration as revealed 
by the number of haustorial cortical folds. Although it is a very 
good ho.st, there is danger of sandal plants caught up in a clump 
being squeezed by the bamboo culms and suppressed by their heavy 
cover overhead. 
(143) Bambvsa auricvlata — (Deciduous). — Dr. Barber mentions 
this among the sandal hosts in Appendix I but does not say whether 
he found any root-attachments. I have not seen this species 
attacked. 
(144) OcTilandra Rheedii — (Evergreen). — The roots of this 
species are attacked but not so extensively as those of the bamboo. 
On a rhizome about a foot long with numerous roots there was onlv
