Long cultivated in European gardens. 
The above description is from Scott-Elliot, 4423, noted to have yellow flowers, 
which have become in drying mauve-purple, as stated by Nees. The 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.

branched shrub without spines ; young branches canescent with minute

Sessile or with a petiole ,}, in. long. Cymes 1-3-flowered, condensed,
