of the leaf-stalks can be manfactured into very strong ropes, 

 also into baskets, brushes and brooms. The outer wood of 

 the stem serves for turnery. 



Cassia acutifolia, Delile. 



Indigenous or now spontaneous in Northern and tropical 

 Africa and South-west Asia. Perennial. The merely dried 

 leaflets constitute part of the Alexandrian and also Tinne- 

 velly Senna. In Victoria it will be only in the warmest 

 northern and eastern regions, where Senna can perhaps be 

 cultivated to advantage. 



Cassia angustifolia, Vahl. 



Northern Africa and South-western Asia, indigenous or cul- 

 tivated. Perennial. Yields Mecca-Senna. 



Cassia Marylandica, L. 



An indigenous Senna plant of the United States of North 

 America. Perennial. 



Cassia obovata, Colladon. 



South-west Asia ; widely dispersed through Africa as a 

 native or disseminated plant. Perennial. Part of the 

 Alexandrian and also Aleppo Senna is derived from this 

 species. Several of the Australian desert Cassias of the 

 group of C. artemisioides may also possess purgative pro- 

 perties. The odor of their foliage is almost that of Senna. 



Catha edulis, Forskoel. 



Arabia and Eastern Africa. The leaves of this shrub under 

 the designation Kafta or Cat are used for a tea of a very 

 stimulating effect, to some extent to be compared to that of 

 Erythroxylon Coca. To us here the plant would be mainly 

 valuable for medicinal purposes. 



Cedronella cordata, Bentham. 



United States of North America. A perennial herb, fragrant 

 like the foregoing. 



Cedronella triphylla, Moench. 



Madeira and Canary Islands. A shrubby plant with highly 

 scented foliage. The volatile oil obtainable from it resem- 

 bles that of Melissa, but is somewhat camphoric.
