FLOWERS 
A flower containing both pistil and stamens is called perfect. 
If containing stamens only it is staminate; if pistil only, pis- 
tillate ; if neither, neutral. If pistillate and staminate are found 
in the same plant, it is called moncecious; if on different plants, 
dioecious. If a species has perfect, pistillate, and staminate 
flowers on the same or different plants, it is called polygamous. 
The perianth is the floral envelope, as a whole, including 
corolla and calyx. It is sometimes found convenient not to 
attempt any distinction between calyx and corolla, the flower 
being described, for example, as having a four-parted perianth. 
The spathe is a large bract or modified leaf surrounding the 
flower-spike, as in Jack-in-the-Pulpit. The spadix is a spike 
with a fleshy centre; for example, the " Jack " of Jack-in-the- 
Pulpit. 
A flower-head, whether composite or otherwise, is classed as 
a single flower, since it has that appearance. Leaves resembling 
flowers, or giving the distinctive color, as in Painted Cup, are 
classed among the flowers. The general color-effect determines 
the placing of the flower. In case of doubt under which of two 
colors a flower falls, try both. In case of doubt between pink 
and purple, give preference to purple, a color botanically very 
inclusive, covering, e.g., lavender, lilac, and violet.
