78 PORTULACEA., 
Var. B; root white; flowers rose-coloured. Native of the 
subalpine regions of the Rocky Mountains, on the west side, and 
abundant at the junction of the Spokan river with the Columbia, 
on dry stony rocks; also of the Flathead and Salmon rivers, in 
similar situations. The roots of this variety are gathered in 
great quantities by the Indians on the west side of the Rocky 
Mountains, and highly valued on account of their nutritive quali- 
ties. ‘They are boiled and eaten as salep or arrow-root, and are 
admirably calculated for carrying on long journeys ; two or three 
ounces a day being quite sufficient for a man, even while under- 
going great fatigue. Perfect flowers of the plant have not yet 
been seen by any botanist, and therefore the genus is not well 
known; and probably may hereafter verge into Talinum, 
Revived Lewisia. Clt. 1826. Pl. 4 foot. j 
Cult. A mixture of loam and brick-rubbish will be a good 
soil for this plant; and it may be propagated by dividing the 
plant at the root, by cuttings, or by seeds.
