PORTULACEjE. VIII. CALANDRINIA. 



Var. (3 ; 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.

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.

 partite (f. 18. a.) ; sepals roundish-ovate. Petals 3-5 (f. 18. b.), 

 hypogynous, or inserted in the bottom of the calyx, distinct or

 linear-lanceolate, acutish ; raceme terminal, few-flowered ; pe- 

 dicels elongated ; bracteas minute, foliaceous : sepals ovate, 

 acute ; stamens numerous. T; . D. G. Native on the Andes of 

 Mendoza and Chili, in many places at an elevation above the 

 sea, from 9,000 to 10,000 feet. The flowers are pretty large, 

 and purple. It ranks near C. linguldtq.

 obtuse, attenuated into the petiole ; indurated bases of petioles 

 imbricated and dilated; peduncles radical, 1 -flowered, naked, 

 one-half shorter than the leaves. I/ . D. G. Native on the 

 Andes of Chili, at El Serro de San Pedro Nolasco. This species 

 is closely allied to C. acaulis, but differs in the flowers having 

 numerous stamens.
