Remarks. Under N. O. 144, Bignoniacece, Bignonia Chica, Humb. 

 et Bonp. of meridional America yields a red dye, and Jacaranda ovali- 

 folia the Green Ebony of commerce. Under N. O. 154. Boraginacese, 

 Anchusa tinctoria, W. Dyers* Bugloss of Britain (one ayxovcra of the 

 Greeks) is the source of Alkanet. I have received also as Alkanet a root 

 used in the Punjab as a dye. It is probably the root of Onosma emodi, 

 Wall. Other species of Onosma and Echium rubrum, and Lithospermum 

 linctorium are in Europe and elsewhere substituted for Alkanet. Under 

 N. O. 164. Acanthacese, a species of Ruellia, produces a blue dyeiu China 

 called Trenching, a name the Chinese also apply to the Woad they obtain 

 from / 'satis indir/otica. In Assam also a blue dye called Room is obtained, 

 according to Griffith, from a species of Ruellia. (Lindley.) Under N. O. 

 176, Polygonacese, Polygonum tinctorum is cultivated in Europe for its 

 blue dve, resembling Indigo ; and other species also yield it. Under 

 N. O. 185, Thymehcese, Daphne Gnidium, and Passerina tinctoria of 

 South Europe, yield a dye. The former is the Casia herba of the Ro- 

 mans, and 6vp,\aia of Dioscorides.

Remarks. See " Drugs." Ricinus Tanarius of Sumatra is used there 

 as a dye. It is the Tanarius minor of Rumphius (lib. v. fig. 121). 

 Crawfurd states that the Tanarius major of Ilumphius (lib. v. 122), 

 which I cannot identify, is used also as a dye in Sumatra under the name 

 of Laka. Cro~0))/tnra tinctoria (rjXiorpoTnov TO /xutpoi', Dios.) of South 

 Europe is the source of Turnsole.
