form the calyx; two of these, standing opposite to each 
other have honey glands at their bases. Inside the sepals 
and filling up the gaps between these are four showy 
petals arranged in the form of a cross, and forming the 
corolla. The petals are delicately scented and have a 
soft velvety appearance. Inside the petals and attached 
to the receptacle are six stamens each, as in the Buttercup, 
consisting of a filament and an anther lobe. Two of these 
are shorter than the other four, and are inserted on the 
receptacle. at a lower level than the longer ones. A

green nectary is situated at the base of each of the two 
shorter stamens (the same nectaries as the ones referred 
to above). In the centre is the pistil, a long bottle- 
shaped body with a slender neck, and a notched and 
sticky top, the stigma. If the pistil be cut through 
vertically, the lower part, the ovary, will be found to 
be hollow and to contain four rows of ovules; these, 
when the flower ripens, will become the seeds, from which 
other plants may be grown. ~
