Remarks. Indigo is the Indicum of Pliny, and TO IvSiKov $CL$IKQV of 

 Dioscorides. There are more than one hundred species of Indiffofera, 

 natives of the East Indies, Arabia, Africa, and equinoctial America. East 

 Indian Indigo is the species chiefly cultivated in India, and /. Anil, W. 

 West Indian Indigo in the West Indies. The latter is also, with other 

 species, cultivated in India. Indigo is one of the most profitable products 

 of India. In Nubia Tephrosia Apollinea, De C. in the countries of the 

 Niger T. toxicaria, and in Ceylon, according to De Candolle, T. tine- 

 toria furnish Indigo. Baptisia tinctoria, R. Brown, supplies it in the 

 Federal States of America. All these are Leguminous plants. The dyes 

 furnished also by IFrightia tinctoria, Don, N. O. 141, of India, Poly- 

 gonum tinctorium of Europe, and Ampelygonium chinense, N. O. 176, and 

 Gymnema ting ens of Pegu, and Marsdenia tinctoria of Sumatra, N. O. 140, 

 are often named as kinds of Indigo. V. infra.

Remarks. Sprengel considers this to be the Almug tree of 1 Kings 

 x. 11, now identified with Santalum album, N. O. 190. Santalacese. 

 See " Miscellaneous Class." Sprengel also identifies it with the Sundul of 

 Avicenna, and it may be the " Red Sanda!wood" he mentions, together 

 with " White." (Lib', ii. Tract, ii. ch. 657.) It may however be the wood 

 of Adenanthera pavonina, or even of Ccesalpinia Sappan (v. supra). 

 Of other Leguminous plants Baphia nitida of Sierra Leone and the 

 Gaboon country furnishes Barwood or Camwood, with which Bandana 

 handkerchiefs are dyed ; Genista tinctoria, W. Dyers' Green-weed of 

 Britain, a yellow, and with Woad a green dye ; and Hcematoxylon campe- 

 chianum of Campeachy, Logwood. Under N. O. 76, the bark of 

 Photinia ditbia, Lind. is said to be used in Nepaul as a dye.
