Csesalpinia Gilliesii, Wallich. (Poinciana Gilliesii, Hooker.) 



La Plata-States. This beautiful rather hardy bush can be utilised 

 for hedges. 



Csesalpinia pulcherrima, Swartz. (Poinciana pulcherrima, Linne.) 



Called "The Pride of Barbadoes," but seemingly indigenous to 

 tropical Asia. A large shrub or small tree. This brilliantly orna- 

 mental prickly plant is highly adapted for hedges in any climes free 

 of frost. The nesting of ants in its trunk, while the growth con- 

 tinues quite normally, was pointed out already by Roxburgh. 



Csesalpinia Sappan, Linne. 



South-Asia. The wood furnishes a red dye, which is largely 

 exported. This shrub can also be adopted as a hedge-plant. The 

 lac-insect has recently taken to it [Watt]. 



Csesalpinia sepiaria, Roxburgh. 



Southern Asia, east to Japan. There often utilised as a hedge- 

 bush. It can advantageously be mixed for hedge-growth with 

 Pterolobium lacerans (R. Br.), according to Dr. Cleghorn. It 

 furnishes a red dye- wood. 



Caesalpinia tinctoria, Dombey. 



Chili. The bark yields a red dye. 



Caesalpinia vesicaria, Linne. (C. bijuga, Swartz.) 



West-Indies, on dry savannas and limestone-rocks. This tree 

 furnishes part of the red Fernambuc-wood of commerce, for dye- 

 purposes and select implements. 



Cajanus Indicus, Sprengel.* 



The Catjang or Dal ; in Assam called Geeloa-mah, often also 

 Arhar. A shrubby plant of tropical Africa and perhaps Asia, but 

 ascending to 6,000 feet in the extra-tropical latitudes of the Hima- 

 layas. One of the upland varieties will endure a few degrees of 

 frost [C. B. Clarke]. In Jamaica it is cultivated up to 4,000 feet 

 according to Mr. W. Fawcett. On the Richmond River in New 

 South Wales it attains a height of 6 feet. It sustains itself on dry 

 ground, and yields the pulse known as Dhal, Urhur and Congo-pea. 

 The plant lasts for about three years, attains a height of 15 feet, and 

 has yielded in the richest soil of Egypt 4,000 Ibs. of peas to the acre. 

 A crop is obtained in the first year. The seeds can be used as peas 

 in the green state as well as when ripe. Two varieties exist, C. 

 flavus, a much smaller plant, yielding less but ripening in 3 or 4 

 months, and C. bicolor, larger and more prolific, but requiring some- 

 times 9 months to ripen [Dr. G. Watt]. Has the advantage over 

 most other kinds of pulses in being perennial. Even more utilised
