eared. Flowers large, bright red with purple standard, two or three in 
a cluster; June and July. Annual. 
L. tuberosus (tuberous). Rootstock creeping, perennial; small 
tubers on the rootlets. Stem angled, 2 to 4 feet. Leaflets, one pair 
only, oval, with short tendrils. Flowers crimson, large, three to six in a 
raceme ; June to August. 
Culture Sweet and Everlasting Peas should be in every garden. 
Their cultivation is of the simplest; and if the seed be 
obtained from one of the best houses a brilliant display is assured in any 
but the poorest of garden soils. The seeds should be sown early in 
spring in the open ground, in rows an inch and a half deep, or in circular 
patches a yard or so in diameter in the herbaceous border, suitable 
branched sticks being inserted to support the stems. They are frequently 
sown in pots, germinated under glass and planted out when a couple of 
inches high; but it is far better to sow where they are to flower. On 
dry soil they must be watered several times a week in the absence of 
showers. To prolong the blooming period the dead flowers should be 
picked off immediately; otherwise the strength of the plant will be 
exhausted by the swelling pod, and the flowering will cease. The 
perennial species may also be propagated by division of the rootstock, 
early in spring. If the seed-bed has been prepared by well digging in 
manure during the previous autumn, the result will well repay the 
trouble taken. 
Description of A portion of the stem of Lathyrus odoratus is shown, 
Plate 7i. the flowers of the natural size of the type, which is much 
exceeded by the improved strains now commonly grown. Fig 1 is a 
section of the flower; 2, a single seed; and 3, a seedling. 
Phaseolus (the old Greek name). This genus, allied to Lathyrus 
includes the Scarlet Runner (P. multiflorus), the Kidney-bean (P. 
vulgaris), and others that may be used with advantage in covering 
arbours and trellises. They bloom freely and continuously, and combine 
usefulness with ornament. 
SPIRAEAS

Spirvea (the old Greek name). A genus of about fifty species of
