ILLUSTRATIONS OF INDIAN BOTANY 



Involucre usually one scale to each floret, that of the 

 hermaphrodite much larger, forming a common invo- 

 lucre to the capitulum, aristato-mucronate ; those of 

 the females linear, truncated at the apex and adhering 

 at the base to the pedicels. Hermaphrodite corolla 

 large, sub-campanulate,made up of a congeries of quad- 

 rangular cells, very fragile under the knife. [The plant 

 which forms the type of this genus is Sph<Branthus 

 amaranthoides of Burman and D, C., but which is amply 

 distinct both in structure and habit from Sph<£ranthu3,} 

 Peninsula, rare, Tanjore, Burmah, Ceylon.
