Peduncles many-flowered ; leaves linear-lanceolate. 



The slender oldenlandia, with small narrow leaves, is found in the most lsuren sa 

 vannas, and rises generally to the height of ten or fourteen inches.; the footstalks of 

 the flowers are sometimes simple, hut oftener branched, and rise immediately from the 

 alue of the leaves, or shoot from the top of the smaller ramifications ; all the parts of the 

 plant are very delicate. Browne. The flowers are white and small, the stems almost 

 prostrate, four-cornered, with opposite branches; leaves long, narrow, opposite^ 

 marked with a longitudinal line; stipules opposite, connecting the leaves, with three 

 awns at the tip,

Umbels naked, lateral, alternate; leaves linear. 



This species is a native of the East Indies, and is called" Indian madder or chP, and; 

 was introduced into this island, in the year 1791, by Hinton East, Esq. but, like many 

 other valuable exotics, has been much neglected. It is a small plant,- biennial, rarely 

 triennial ; root long, slender, with lateral fibres ; when fresh, the bark is orange-co- 

 loured : stem erect, round, branchy; branches and leaves opposite. Flowers termin- 

 ating, small, white, numerous; umbel composed of small three-cleft mnbellates; 

 bractes minute, awl-shaped. It thrives in sandy ground, and is much cultivated in the 

 East-Indies, and used in dying red, purple, a deep clear brown, orange, and to paint 

 the red figures on chintz. It is the burk of the root only which possesses this r'ying 

 principle; when fresh it tinges the spittle yellow, ami leaves a slight degree of acri- 

 mony. It impregnates cold water or spirits with a, straw colour: to boiling water it 

 gives a brownish porter colour. The watery 7 infusions and .spirituous tinctures are 

 changed into a bright and deep red by alkaline substances; and are rendered paler, or 

 nearly destroyed, by acids. The colouring powers of this root are said to improve by, 

 keeping three or four years.
