light sandy soil. They comprise tints of pink, red, pur- 

 ple, white, and of brilliant canary-yellow, but have need 

 of bright sunshine to open well. The handsomest species 

 cultivated, O. speciosa, from the Cape, has large reddish- 

 purple flowers with a yellow tube, and is tender. 0. 

 violacea, Violet Oxalis, from North America, stands our 

 winters outdoors, 0. ceniua, or caprina, from the Cape, 

 has bright yellow flowers, sometimes double, and is safest 

 in pots. 0. rosea, Pink Oxalis, a South American 

 annual, is a charming little plant, which on light soils, 

 with sparing waterings, makes an edging that remains a 

 long while in flower. 0. Deppei may be also employed as 

 a pleasing edging in kitchen-gardens. O. floribunda 

 deserves notice. 



Pea (Everlasting). — The genus Lathy r us comprises 

 several very ornamental and favourite species, some of 

 which are perennials with hardy rhizomatous and even 

 tuberous roots, whilst others are elegant annuals. Of the 

 former, L. tuberosus, Gland de Terre, or Earth- Acorn, with 

 bright pink flowers, which appear in June and July, in 

 bunches of five or six, was anciently cultivated as an 

 esculent plant, and will grow in any garden soil, from 

 seeds, or tubers planted in autumn. L. grandiflorus, 

 the Large-flowered Everlasting Pea, with handsome rosy 

 flowers shaded from dark to light, may be multiplied by 

 seeds token such are produced, or cuttings of the root 5 ; 

 likes a sunny aspect, and a slight mulching with manure 

 in winter. The least-known species, which deserves to 

 be more extensively cultivated, is L. Magellanic us, Lord 

 Anson's Pea, whose elegant foliage and bright blue 

 flowers adapt it for covering a trellis on a wall. Propa- 

 gate by root-division, and mulch or cover with litter in 

 winter. Tlie Everlasting Pea, which is to be found in 

 almost every old-established garden, is L. latifolius, with 

 pink flowers (of a rather dull hue, however), which have 

 the merit of making their appearance every summer with 

 admirable punctuality, and without exacting more than 

 the most ordinary care on the part of the gardener. 

 There is a white variety less widely diffused, but of
