XVIII.—POLYGALEAE.

This order which is very generally distributed over the globe, being found in every quarter of it, and in almost every kind of soil and climate, abounds in species, but is very limited in the number of genera, the latter, standing in the proportion of only about 1 to 19 or 20 of the former, on whole order. Among its species every form of vegetation is found, from the very minute annual scarcely 3 inches high, up to large sized trees. Many of these are milky plants, with round stems, and ex-stipulate, scattered, simple, entire, sessile, leaves, or having the limb attenuated into a short petiol. The flowers, which are sometimes solitary, often racemose, with the pedicels furnished with bractiee, are hermaphrodite and irregular in their form, often small, and inconspicuous, but showy in some of the Polygalas.
