SIBERIAN AND BUCHARIAN RHUBARBS, 123 
ART. XXIV. — FURTHER NOTICE RESPECTING SIBERIAN AND 
BUCHARIAN RHUBARBS, WITH SOME REMARKS ON TASCH- 
KENT RHUBARB. 
By Jonathan Pereira ; m. d., f. r. s. 
In the paper published in the last number of the Phar- 
maceutical Journal on some rare kinds of rhubarb which 
have recently appeared in British commerce, I noticed four 
varieties of rhubarb. I have subsequently received from 
Mr. Faber some additional information respecting two of 
these, viz., the Siberian and Bucharian sorts, which I beg 
to communicate to the Society. 
I may observe that the following information has just 
been received from one of the first drug-houses in St. Peters- 
burg, namely, Messrs. Dyrssen & Co., than whom, Mr. 
Faber assures me, no person can be expected to give infor- 
mation upon which more reliance can be placed. The let- 
ter is dated March 18th. 
1. Siberian Rhubarb. 
In my former paper, I stated that the rhubarb which I 
called Siberian, had been sent to thiscountry as Bucharian. 
But three circumstances led me to conclude that it was 
Siberian. First, it differed from Bucharian rhubarb which 
arrived here in 1840. Secondly, it was suggested by one 
of Mr. Faber\s correspondents that it was not Bucharian 
but Siberian ; and thirdly, it agreed with the Siberian rha- 
pontic root described by Grassman. 
My conclusions, it appears, are correct, and the drug firm 
above alluded to, in their letter to Mr. Faber, just received, 
observe, " from your minute description of the three chests 
of rhubarb, we are quite sure that it is and can be no other 
than our Siberian radix rhapontica. It is a distinct species, 
and is not the root branches of either Bucharian or crown 
rhubarb. "
