Part II. OXALIS—OXYTROPIS—PACHYPHYTUM, 267 



OXALIS 'E'L,QiSl'£,\rSi'DK.— Many-flowered Wood Sorrel. 



A FREE-FLOWERING kind of Wood Sorrel, apparently quite 

 hardy in all soils, and producing numbers of rose-coloured 

 flowers with dark veins, for months in succession. The leaflets, 

 three in number, are jroundish-egg-shaped, concave at the apex, 

 and hairy. There is a white-flowered variety as free to flower 

 and in every way as valuable as the rose-coloured form. Both 

 are very useful for rockwork, for the margins of borders, and are 

 easily increased by division. This appears to be the commonest 

 kind of Oxalis in cultivation. A native of South America, and 

 hardy enough to encourage one to attempt to naturalise it on 

 any rocky place or about ruins. 



There are other species of Wood Sorrel obtainable, and worthy 

 of a place, especially on very dry sandy soils, and among them, 

 O. lobata, a yellow, and O. speciosa, a rose-coloured kind, are 

 perhaps the best. The elegant O. rosea is an easily grown 

 annual kind, suitable for grouping with choice rock-plants. 



OXYTROPIS PYRENAICA. — Pyrenean Oxytrope. 



A \5ERY dwarf species, with pinnate leaves, composed of from 

 fifteen to twenty pairs of leaflets, each about a quarter of an inch 

 long, slightly concave, and clothed with a short silky down. 

 These barely rise above the ground, as the short stems are 

 nearly prostrate, and seldom exceed a few inches in height ; the 

 flowers, borne in heads of from four to fifteen, are of a purplish 

 lilac — the upper petal or standard barred with white in the centre. 

 Not a showy but withal a desirable little plant for those parts of 

 rockwork devoted to very dwarf subjects. A native of the Pyre- 

 nees, rare in gardens, increased by seed or division, and should 

 be planted on well-exposed and bare parts of rockworks, in firm, 

 sandy, or gravelly soil. Flowers in early summer. 



PAOHYPHYTUM BEACTEOSUM.— ^z/w^r^rac/J. 



I SHOULD not have mentioned this plant here had it not been 

 used with a singularly good effect of late associated in several 

 instances with dwarf hardy succulents. It is a fleshy succulent 

 plant, a native of Mexico, belonging to the Crassula order, with 

 leaves about half an inch thick, somewhat spoon-shaped, but 

 narrowing very gradually from the wide apex to the thick base,
