=The Flowers= are in small axillary clusters in the axil of the leaf between the thorns, and are greenish-yellow with a 5-pointed calyx, 5 minute petals, 5 stamens, a bifid stigma and a yellow receptacle. They appear in December. =The Fruits= are similar, but larger than those of the other species and are a rich red-brown, with a shiny, brittle skin, a white, mealy flesh and a large stone. They are not edible. =Uses.=—The fruits are chewed, but not swallowed, as a cure for toothache. The wood is used for making bows of superior quality. [Illustration] =ZIZYPHUS SPINA-CHRISTI= Willd.—_Kurna_. RHAMNACEAE. This species is generally found in and around towns where it attains a height of over 40 feet with girths of over 6 feet. Closely resembling _Z. Jujuba_, it can be distinguished at once from that species by the absence of white on the underside of the leaf. The bright green foliage and tangled crown, commonly spherical in young trees, are readily recognised. Large trees have a great thicket of long, slender twigs that intertwine and emerge here and there from the crown to a distance of several feet, after the manner of the Bramble. It is a good shade tree and this and its edible fruits are the reasons for it being planted and preserved in towns. The tree is a favourite nesting site for small birds which build their nests in association with a wasp whose “honeycomb” guards the entrance to the nest. =The Bark= is grey and deeply scoured with long fissures and ragged, ridged scales which fall in large sections 6 inches long. The slash is cerise. =The Thorns= are in pairs on the white twigs. The upper thorn is long and straight and the lower is shorter and sharply recurved. They are light brown and the leaf rises between them with the flowers in the leaf axil. The straight thorn points well forward. =The Wood= is pale red, often with wide, brown discolorations; the sapwood is white. In transverse section the rings are only faintly marked; the pores are very small, numerous and single: the rays, invisible to the unaided eye, are extremely fine and close together, showing as small reddish bands in radial section. In vertical section the pores are long and fine, the grain close, and the colour banded in faint shades of the ground colour. The wood saws and planes well, is sound, though liable to knots, fairly heavy and moderately hard. The weight is 50 lbs. a cubic foot. =The Leaves=, though they are arranged spirally round the twigs, tend to assume one plane. The upper surface is bright green with a bluish bloom and the venation roughens the underside. They are 1-2 inches long and ¾-1 inch wide, the palmate venation composed of three principal nerves, spreading from the base.
