« indica” ”” appear = have fallen into disuse in Java, and the name 
I. leptostachya, given to this form by Zollinger under the mistaken 
idea that this is the plant to which De Candolle applied the name 
I. leptostachya, came to be used for it. This name, I. leptostachya, 
I. tinctoria ; it connotes n rican speci I. arrecta 
Hochst. , equally remote from the Ontidolledn sabi to which the 
name was originally given. The no orthern form of I. tinctoria ex- 
tends to Formosa; it is also the form of J. tinctoria that was first 
introduced to the West Indies from the East Indies; and is the 
orm of I. tinctoria figured by Sloane, t. 179, fig. 2. This makes 
it also the J. tinctoria of Lunan . Hort. Tamaicensis, in so far as 
that is based on Sloane’s figure. The specimen from which Sloane’s 
figure was drawn has glued down on the same page fruits of I. Anil, 
but these tt not been used in drawing the figu 
If, however, the view expressed by Berg, Baker, and Vatke, that 
rer ayivesttan orm of this species deserves to be recognized as @ 
pecies under the name J. Bergii Vatke—and we are bound to admit 
that, apart altogether from the high authority of the writers who 
have given expression to the view, there is a good deal to be said 
for it on sry eee era es will become necessary to accept 
the view of Gaertner, Lamarck, and Zollinger, that the form culti- 
vated in aethestt “Tndia a is a species apart from J. tinctoria L., to 
be known as I. suwmatrana Gaertner. The differences between these 
two cultivated plants are as salient and as constant as the differences 
between J. Bergit and either of them 
There are not in collections a large number of specimens of 
I. tinctoria from America; it does not appear ever to have been 
greatly in favour there as a source of indigo. Very few indeed of 
these specimens = edlietils to the Madras, bhihasnt all being = 
sober form of the species. Most are from the West Indies ; 
few are from Plorida pmtens of Key West); none have been soak 
municated from the continent of America. From Africa, apart 
from the wild forts in Nubia which we think probably the original 
condition of - tinctoria, cultivated examples have been communi- 
cated only from the Mascarene Islands, the Canaries and Cape de de 
Verde Seaside, ‘Siiedtbe: and from places near the coast both on the 
Mozambique and on the Angola-Senegal side. It is interesting to 
notice that practically all the specimens from Angola to Senegal 
are of oe northern form; many of the Mascarene, Mozambique, aD 
ieee he are of the southern or Madras cultivated form.
