P. runcinatum, Ham. 7^00-10,000 ped. alt. 



Abundant. 



P. chinense, L. 7000-9000 ped. alt. 



Abundant. Why is this plant not Coccoloba ? Polygonum is 

 specially defined as having a dry calyx in fruit, Coccoloba a baccate 

 calyx in fruit. 



P. molle, Don; i. e. Coccoloba totnea, Ham. Abundant in Darjeeling 

 station and up to 9000 ped. alt. 



The fruit of this is distinctly baccate, the sepals coalescing and 

 becoming thick and succulent, so that the fruit is extensively 

 eaten under the native name of Totnye. "Why is Hamilton wrong 

 in calling this Coccoloba ?

P. crispatum; i. e. Coccoloba crispata, Ham. 9000-10,000 ped. 

 alt. 



Abundant. A most beautiful plant, the large numerous flowers 

 varying from white to rose, This is a true Polygonum, i. e. the 

 sepals quite dry on the fruit. It is at once (when out of flower) 

 recognized from all other Polygonums by the parallel veins of the 

 leaves. I add a description : — 



P. crispatum, Ham., sub Coccoloba. Erecta ramosa 4-6-pedalis 

 ramis lanato-pilosis. Ochreae breves latse scariosae pilosse margiue 

 subintegro. Folia petiolata elongato-lanceolata integra supra viridia 

 aparsim pilosa, subtus argenteo-tomentosa venis (20-30 paribus) 

 exaete parallel is utrinque insigniter ornata. Corymbi laxe subdicho- 



tomo-paniculati : flores laxi pro genere majusculi : bracteolse rotun- 

 datae fere glabrae. Stamina 7-8. Styli 3 ad basin liberi apice capi- 

 tati. Achsemum ovatura acute triquetruni, sepalis siccis marcescenti- 

 bus laxe circumdatum. 

 Species eximia a P. chinensi (cui a cl. Meisner reducta est) longe 

 remota. 



There are several other species of Polygonum that may be col- 

 lected at 7000-8000 ped. alt. ; the above were all I got on Tonglo 

 itself. The beautiful Himalayan Polygonums of the section Bi*-
