of Polygonum and Fagopyrum. 107 



small, 4-sepalous, 6-androus, semi-trigynous, in rather large heads which 

 are two together and usually slightly stalked; the peduncles bearing 

 stalked glands ; bractese lanceolate, acute, with a pale white margin, and 

 slightly rough and glandular. Fruit compressed, the faces convex, orbi- 

 cular and acute, beautifully covered with minute reticulations, leaving 

 deep pits between ; the calyx is not agglutinated to the fruit, as is usual 

 in this section. 



The two varieties are very closely connected, some specimens being almost 

 exactly intermediate. 

 Mussooree, during the rains.

P. sphaerocephalum. Meisn. in Wall. iii. 60. 



Stem procumbent, rooting, woody, the branches upright, glabrous. Leaves 

 all stalked, cordate, acute, glabrous, fringed with minute spinous teeth, 

 pointing forwards, the petioles longish, slightly winged, without auricles. 

 Stipules blunt, entire, slightly hairy. Flowers 5-sepalous, 6-androus, 

 semitrigynous, with paleaceous acute bractese, in rather large and soli- 

 tary heads upon very long peduncles which are glabrous below and glan- 

 dular-hispid in their upper part. Fruit too young for description.
