NATURAL HISTORY OF PLANTS. 



Some authors have considered this a distinct genus ; we can only 

 make it a section of the genus Ccesalpinia. It contains half a dozen 

 species, 1 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 Hoffmanseggia; which 

 has the flower and glandular calyx of certain Ccesal/jinias. 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 Ccesalpinias, but coming closer to that of Erytliro- 

 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 Ccesalpinia. 

 There are some twelve species 3 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 Ccesalpinia will 

 consist of no less than fifteen sections, 5 comprising some threescore 

 species from the warm and temperate regions of all parts of the 

 world. 



The far-distant series Copaiferea has been indicated as the place 

 for Zuccagnia punctata,'' a small shrub from the Chilian Andes,
