 few cauline reduced, oblanceolate, all acute, glabrous, thin : 

 thyrsus either capitiform or with a smaller cluster of flowers an 

 inch below it : calyx elongated, the sepals subquadrate-oblong 

 or even spatulate-oblong, abruptly acuminate, their scarious 

 margins as wide as the herbaceous middle portion, the whole 

 calyx sparsely [)ubescent: corolla J inch long, dark-purple,
