Note 1 — CHAP. III.

: There are said to be fourteen species of the Nilloo (Strobilanthes) in Ceylon. They form a complete under-growth in the forest five or six feet in height, and sometimes extending for miles. When in bloom, their red and blue flowers are a singularly beautiful feature in the landscape, and are eagerly searched by the honey bees. Some species are said to flower only once in five, seven, or nine years; and after ripening their seed they die. This is one reason assigned for the sudden appearance of the rats, which have been elsewhere alluded to (vol. i. p. 149, ii. p. 234) as invading the coffee estates, when deprived of their ordinary food by the decay of the nilloo. It has been observed that the jungle fowl, after feeding on the nilloo, have their eyes so affected by it, as to be partially blinded, and permit themselves to be taken by the hand. Are the seeds of this plant narcotic like some of the Solanaceaæ? or do they cause dilatation of the pupil, like those of the Atropa Belladonna?
