NYMPHAECEAE. 
^ymphaea odorata Ait. (Water-lily). Plowright states that in the Hebrides 
a dye is used, derived from this plant. 
BEEBERIDACEAE. 
Berberis vulgaris L. (Barberry). Prom this is made a yellow basic dye 
known commercially. Prom the Oregon Grape {B. aquifolium Pursh) a similar 
dye is obtained. 
MENISPERMACEAE. 
The Palse Colomba-root {Coscinium fenestratum Colebr.) furnishes a yellow 
dye used in the East Indies. 
LAURACEAE. 
The Persea Lingue Nees. of Chili contains tannin. 
PAPAVERACEAE. 
Sanguinaria canadensis L. (Blood-root, Red Indian-Paint, Red-root, Blood- 
wort). Its roots yield a red pigment which the Indians formerly used to 
color their bodies. The Tama Indians use this as a dye. 
The Garden Celandine (Chelidonium sineyise DC.) is a commercial source 
of a yellow dye, and the Corn or Pield Poppy (Papaver Rhoeas L.) cultivated 
in our gardens, furnishes through its petals a coloring matter used in red ink. 
CRUCIFERAE. 
The cultivated red Cabbage (Brassica oleracea L.) furnishes the red coloring 
material known as caulin. The Wallflower {GheirantJius Cheiri L.) is the 
source of a commercial yellow dye. The Dyer’s Woad, Dyer’s Weed, Pastel, 
or Ash-of -Jerusalem (Isatis tinctoria L.) as well as J. indigotica Port, and I. 
lusitanica Brot. of China yield indigo. The beautiful Kendal green was made 
by “topping” the blue from I. tinctoria with a yellow dye from Weld {Reseda 
Jbuteola). 
ANONACEAE. 
The Yellow-dye Tree {Xylopia polycarpa Oliver) of Soudan contains a yellow 
dye-principle. 
MONIMIACEAE. 
The bark of the Boldo {Peumus Boldus Molina) contains a dye. 
CAPPARIDACEAE. 
The Capers {Gapparis^ spinosa L.) furnish a yellow dye. 
DROSERACEAE. 
Prom the Sundew {Drosera WJiittalcerii Planch) is obtained a dye used in 
coloring red to brown. 
RESEDACEAE. 
The Yellow Weed, Dyer’s Rocket, Weld, or Dyer’s Weed {Reseda Luteola L.) 
is the source of the commercial “Dutch Pink” and is said by Plowright to 
furnish the best yellow dye in Great Britain. It makes a yellow, blue, or 
green dye according to the mordant used and, according to Smith, is used 
largely in coloring paper-hangings. In coloring to produce Kendal green, the
