152 SPOLIA ZEYLANICA. 
Sarcostemma brunonianum occurs frequently, especially in 
the bush country. 
Dregea volubilis is also fairly abundant near to Liyangolla 
and Muppane. 
Of the Loganiacee, the well known Strychnos nua-vomica 
is most abundant. It is remarkable, in view of its being so 
common, that cases of children poisoning themselves by 
eating the seed are rarely heard of. 
S. potatorum occurs, but is not abundant. I looked out for 
cases where the seeds were used for precipitating muddy 
water, but failed to find an instance of its use in this direction. 
Of the Gentianacez, Hxacum zeylanicum occurs in fields, 
but the flowers are much paler than in wet-country examples. 
Of the Boraginex, Cordia myxa is fairly common. T'ourne- 
fortia argentea occurs on the seashore, but is not plentiful. 
Heliotropium indicum is very common in waste ground. 
Of the Solanacez, mention need only be made of Datura 
fastuosa, which appears in nearly all the more established 
gardens. The various “ Battus”’ I can pass over, as being 
common all over the Ceylon low-country, and as probably 
introduced. 
Of the Scrophulariacez I desire to draw attention to only 
one, Centranthera procumbens, owing to its presence in a dry 
country being remarkable. I found it on two occasions only, 
first between Nangalla and Danakiriya, and the second time 
about five miles south of Liyangolla. On both these occasions 
I asked the villagers if they could name it, but without success. 
Its presence is singular, as it is generally to be found only in 
the wet zone, or in a country where extremes of drought are 
not experienced. 
Of the Bignoniacese, Oroxylum indicum is moderately 
common, but I think there is little doubt that it was introduced 
for the sake of its medicinal value. Dolichandrone rheedit 
occurs near the coast, near standing water. Stereospermum 
chelonioides is fairly common. Its wood was used by the 
Veddas for bows. 
Of the Pedaliacese, Pedalum murex is common near the 
coast, and is used by both the Sinhalese and Tamils for a 
demulcent. Martynia diandra occurs on the fringes of villages
