Long cultivated in European gardens. 



Tlie above description is from Scott-JElliot, 4423, noted to have yellow flowers, 

 which have become in drying mauve-purple, as stated by Nees. Tlie descriptions of 

 the old garden plant recede in various ways ; the wild plant appears a typical 

 Barleria; Jacquin figures the stamens as 4, fertile, equal ; the anthers are said to be 

 sometimes tailed, the stigmas abnormal, &c.
