A medicinal plant from British Columbia—In November, 1907, 
r. J. F. Davison forwarded to Kew some roots of a plant 
collected by his father, Colonel Davison, in British Columbia. In 
the letter which accompanied the specimens, the following informa- 
tion is given. “I am sending some roots of a plant something 
between celery and carrot with which the Indians cure a sore throat. 
They chew a small piece about the size of a pea but do not swallow 
it .... I got these about 6,000 fect above sea level . . . . neara 
stream.” 
Colonel Davison, in a recent letter, informs us that the plant is 
called by the Indians “ Tiu Piute.” The root is also boiled to make 
a tea, and used by the Indians for fever. He adds that his guide 
had a very bad sore throat, and an Indian gave him some of the 
root to chew, which cured him. 
The roots were collected high up the mountains above Kootenay 
Lake, near Mount Hooker, not far from Nelson. 
Para-Rubber in Assam.—We have been informed by a corre- 
spondent that Para rubber (//evea brasiliensis) has been success- 
fully grown on an estate in Assam for the last four years. The 
Sibsagar District, on the Dekhu River just at the foot of the Naga 
Hills ; the Naga path passes through it, and there used to be a guard 
stationed there some 25 years ago. 
‘Our manager at Behubar (that is the name of the garden) 
wrote in March, 1909, ‘My Para rubber trees have got through the 
cold weather all right, they have nearly all shed their leaves which 
they are supposed to do when they are about four years old, and 
have already begun to throw out new shoots. I really think they 
will do all right from now on ; the stems of some of them are quite 
15 inches in girth,’ and in December, 1909, on his return from leave 
in England, he writes ‘The Para trees are looking very well and 
have put on a lot of growth this year and thickened out a lot. I 
am in hope some of them may seed next year. I wish we had more 
Para rubber and ready for tapping. I had no idea it would have 
done so well.’ ” 
It is hoped that specimens from these trees may be received for 
examination.
