318 FOREST CULTURE AND 
and Southern Brazil. The Mate. This Holly-bush 
is inserted into this list rather as a stimulating me- 
dicinal plant than as a substitute for the ordinary 
Tea-plant. Chemical principles : Coffein, Quina-acid, 
and a peculiar tannic acid, which latter can be con- 
verted into viridin-acid. 
Ilicium anisatum, L.— China and Japan. The 
Star-Anis. An evergreen shrub or small tree. The 
starry fruits used in medicine and as a condiment. 
Their flavor rests on a peculiar volatile oil with Ane- 
thol. This species and a few others deserve culture 
also as ornamental bushes. 
Indigofera Anil, L. — Recorded as indigenous to 
West India, and as extending naturally through Con- 
tinental America from Carolina to Brazil. A shrub 
several feet high. Pods sickle-shaped, short, com- 
pressed. One of the principal Indigo plants under 
cultivation both in the eastern and western hemi- 
spheres. Only in the warmest parts of our colony can 
we hope to produce indigo with remunerative success. 
But many of the hardier species seem never yet test- 
ed for pigment. Already 114 are recorded alone from 
extra - tropical Southern Africa. An Indigofera of 
Georgia, said to be wild, perhaps I. Anil, yields an 
excellent product. The pigment, in all instances, is 
obtained by maceration of the foliage, eration of the 
liquid and inspissation of the sediment. 
Indigofera argentea, L. (I. coerulea, Roxb. )— 
‘Tropical and extra-tropical Northern Africa, Arabia, 
India. A shrub several feet high, closely allied to I. 
Anil, and likewise a good indigo-plant. 2% 
Indigofera tinctoria, L.—Warmest part of Asia, as 
far east as Japan, recorded also from tropical Africa
