clined to follow Linnaeus and make 2 species here ; but they are con- 

 nected by intermediates. The large broad-leaved woolly plant with 

 large flowers is handsome enough for garden cultivation.

An erect annual, 6-18 in., stem much branched, often 

 angular, glabrous; 1. very variable in size, 1-3 J in., usually 

 about i| in., lanceolate-linear to lanceolate, much tapering to 

 base, subacute, glabrous, thin, petiole obscure; fl. small, on 

 very short ped.; cal.-tube cylindrical, oblong, glabrous or 

 slightly pubescent, segm. short, acute; pet. very small, not 

 longer than cal.-segm.; capsule short, ^-f in., cylindrical, 

 somewhat inflated, glabrous, 4-veined ; seeds very numerous 

 in several rows in each cell. 



Low country, especially in the dry region ; very common. Fl. 

 December-May ; yellow.

There is some doubt as to what this should be called. Linnaeus first 

 named it L. perennis, and afterwards L. oppositifolia, both of which 

 names must be rejected as contrary to fact. L. zeylanica, Pers. (1805) 

 would have the next claim, but it was not properly published till 1825 

 (in Spreng. Syst. Veg. i. 444). 



Hermann gives a number of native names for this, including 

 ' Kekirinda,' and says it is used as an eye-medicine.
