of Polygonum and Fagopyrum. 105 
Stem erect, from 2 or 3 inches to a foot in height, slender, nearly simple, but 
often forked near the summit, bearing scattered hairs pointing down- 
wards, the internodes long. Leaves small, ovate or oblong, on short 
stalks, hairy on both sides, not ciliated. Stipules short, lax, hairy. 
Flowers small, in small few-flowered, mostly sessile and solitary heads, 
which are surrounded by 2 or 3 small leaves; stamens 8; stigmas 3, 
nearly sessile; bracteæ minute, paleaceous ; pedicels very short and 
jointed just below the flower. Fruit 3-angular, longer than the peri- 
anth, shining, but very minutely punctured, pale brown. 
In conformity with the views of Professor Meisner I have referred this plant 
to the present section, with the characters of which it does not exactly accord. 
See Meisn. in Wall. iii. 59. The varieties «. cœæspitosum and y. alpestre of 
Meisn. do not occur among Professor Royle's specimens. 
This plant has exactly the habit of Kenigia islandica.
