Derivations. The name, Gymnocladus, is derived from the Greek gumnos, naked, and klados, a branch, from the naked 
appearance of the branches. The genus Guilandina was named in honour of Melchior Guilandin, a Prussian traveller in Africa, 
and demonstrator of botany, at Padua.

^HE genus Gymnocladus comprises but one species, a deciduous 
tree, native of North America, with upright branches, and incon- 
spicuous buds. It was constituted by M. Lamarck, from the 
genus Guilandina, which at present contains but one species, the 
Guilandina bonduc, or Bonduc-tree, a native of India. The 
Gymnocladus is nearly allied to the Tamarindus indica, a large, 
beautiful, spreading tree, indigenous to the East and West Indies, Arabia, and 
Egypt, from which the tamarinds of commerce are produced. Its pods, like 
those of the tamarind-tree, may be preserved, and are said to be wholesome, and 
slightly aperient.
