106 BEAUTIFUL FLOWERS OF KASHMIR [Plate 50<br />
usually yellow-green and purple ;<br />
sometimes conspicuous from<br />
a petal-like border. The margins of the gland are rounded<br />
and entire, or crescent-shaped with projecting horns. In the<br />
same involucre there are many male flowers. Each male<br />
flower consists of one stamen without sepals or petals. In<br />
the centre of each involucre there is a female flower surrounded<br />
by the male flowers. The female flower consists only<br />
of a 3-celled ovary supported on a stalk and protruding from<br />
the involucre and from between the male flowers. The ovary<br />
is surmounted by 3 usually branched styles. The fruit is<br />
a 3-lobed capsule which splits into 3 cocci, each containing<br />
one seed.<br />
