o/" Polygonum ««f/ Fagopyrum. 105 



Stem erect, fiom 2 or 3 inches to a foot in height, slender, nearly simple, but 

 often forked near the summit, hearing scattered hairs pointing- down- 

 wards, the internodes long-. Leaves small, ovate or oblong, on short 

 stalks, hairy on both sides, not ciliated. Sfiptiles 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 : bractepe minute, paleaceous ; pedicels very short and 

 jointed just below the flower. Fruif 3-angalar, 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 Rleisn. in Wall. iii. 59. The varieties a. ccespitosum and y. alpestre of 

 Meisn. do not occur among Professor Royle's specimens. 



This plant has exactly the habit of Kœnigia ishmdica.
