Rheum Ribes, Gronov. PoLYooNACEiE. 



The edible rhubarb, rewand, rewand-chukrl, chukrl, revjds, 

 rlwds, reivdsh, reivdshk. Indigenous all over the moister 

 localities from 3000 feet and upwards, occurring in great 

 expanses, over wet clay soil, on a northern exposure, on the 

 Paropamissus range and the higher hills in Khorasan, 

 marking the country most characteristically in the autumn 

 with the brilliancy of its almost scarlet foliage. The natives 

 are very fond of collecting and eating raw the young shoots 

 of the flowering stems, not the leaf-stalks ; they surround the 

 sprouting stems with stones, to blanch them as well as to 

 protect them from the goats and sheep, until they have grown 

 large enough to be worth collecting to eat. The root-stock 

 is employed in dyeing leather of a red colour. 



Rheum, species. Polygonace^. 



The medicinal rhubarb, reivand-i-chlni, is imported in 

 some quantity from China through Turkistan. 



Rheum tataricum, Lmn. Polygonace^. 



Fools'-rhubarb, rcivand-i-deiodna, rewdsh-i-deivdna, reivand- 

 i-megdn ; ishkin (Turkomani). This grows on the great 

 alluvial plains of the valley of the Hari-rud to the north of 

 Tir-pul, at an altitude of 2000 feet. From the great size of 

 its two or three base leaves, which lie expanded flat against 

 the ground, somewhat resembling Victokia regia leaves 

 without the up-curled margin, it forms a marked object on 

 the plain, more especially when its fruiting-stem is covered 

 with the most brilliant ruby-coloured fruit, from which it 

 receives one of its names. The fruit and the root-stock are 

 both collected to be employed in medicine ; the decoction of 

 the fruit is considered a more powerful purgative than that 

 of the root-stock.
