Soliary terminal means a flower present at the apex of the main stem or its branches. e.g. Trillium grandiflorum.

**No. It doesn't mean that a plant has a single flower.It speaks all about the position of the flower.** Think of roses , they are solitary terminals and are in numbers in each plant, always growing at the apices of branches.
