76 NATURAL HISTORY OF PLANTS. 
Some authors have considered this a distinct genus; we can only 
make it a section of the genus Cesalpinia. It contains half a dozen 
species,’ one a native of eastern Africa, two others of the Indian 
Archipelago and Australia, and the three remaining species of tropical 
America. They are trees whose bipinnate leaves possess numerous 
small leaflets, and whose flowers form simple or compound racemes. 
Another distinct genus has been made of Hof'mansegyia, which 
has the flower and glandular calyx of certain Cesalpinias. The 
species are often of humble stature and herbaceous consistency. But 
several are suffrutescent like certain Pomarias, of which they have 
often the habit and foliage. The fruit has a thin glandular pericarp, 
not that of the true Cesalpinias, but coming closer to that of Hrythro- 
stemon, though a little thinner. The calyx is not always imbricated, 
but sometimes valvate; a character which cannot be unimportant 
by reason of its variability in this same small group Hoffman- 
seggia. Hence we cannot separate these plants from Cesalpinia. 
There are some twelve species’ from Mexico and South America, 
besides two more, whose flowers have well-developed blackish 
calycine glands, and which are natives of the Cape and have been 
made into the genus Melanosticta.! Thus, our genus Cesalpinia will 
consist of no less than fifteen sections,’ comprising some threescore 
species from the warm and temperate regions of all parts of the 
world. 
The far-distant series Copaiferee has been indicated as the place 
for Zuccagnia punctata, a small shrub from the Chilian Andes,
