reddish-brown ends which appear characteristic of sandal. An exam- 
ination with a lens shows numerous haustoria [hh) on the sandal rootlets 
themselves, and their actual attachments to roots of the weed at [f) 
and {g) ; the former (sandal rootlets) can be distinguished from those 
of the weed by their brighter white-brown colour and reddish-brown 
tips ; (d) and (e) are fine sandal rootlets of seedling A detached during ex- 
amination ; /)• — foreign roots ; (c) remains of the petioles of cotyledons. 
Plate V. — Specimens of sandal and Kanuga [Pongamia glalra) 
seedlings grown together in tile-cylinders, A, B and C being sandal 
seedlings, and D and E Kanuga seedlings ; seeds sown on the 25th of 
June 1906, and seedlings taken out on the 29th of October 1906. 
Examination of the network of sandal and Kanuga rootlets wuth a lens 
will reveal numerous haustoria [hh) and attachments between the rootlets 
of both species. Note the vigorous and healthy growth of the sandal seed- 
ling B compared with those in Plate IV and suppression and consequent 
stunted growth of the seedling C : the tap-roots of Kanuga have also 
been attacked by the sandal rootlets and haustoria are formed on them. 
The secondary and tertiary roots of Ranuga are not as abundant as those 
of the same species grown in nursery beds, probably owing to the limited 
space in tile-cylinders in which these specimens were raised. 
Plate FI. — Specimens of sandal and Dirasanarn [Alhizzia Lebbek) 
seedlings grown in tile-cylinders ; seeds sown on the 25th of June 1906, 
and seedlings taken out on the 29th of October 1906. Root-connections 
between the 2 species and the numerous haustoria [hh) are found in both 
sets of the specimens. The height-growth of the sandal seedlings is much 
less than that of the seedling B in Plate V, and the root development 
of the host plant is not so abundant as that of Kanuga : this may partly 
account for the comparatively slow development of the sandal seedlings. 
Plate FI I. — Specimens of sandal [A) and Odesa [B) & (C) [Cleistan- 
thus colUnus) seedlings grown together in tile-cylinders : seeds sown on 
the 25th of June 1906, and seedlings taken out on the 29th of October. 
Root-attachments between both, and haustoria yhhh) of sandal are found 
not only in the networK of rootlets but also on the tap-root of the Odesa 
plant close to the sandal seedling ; note the stouter secondary and tertiary 
rootlets of Odesa plants and the larger size of the sandal seedling and 
its leaves than in the case of other host plants. 
Plate Fill. — Specimens of sandal (A) & (B) and teak (C) & (B) seed- 
lings grown together in tile-cylinders : seeds sown and seedlings taken
