Ameri Rheede Mal. J. ¢. is I. tinctoria a macrocarpa DC. There 
are two specimens of J. tinctoria in Linneus’s herbarium. There is 
a third sheet, at first named by him J. tinctoria, afterwards altered 
es himself to J. Anil. The two left as J. tinctoria are the Madras 
orm of a macrocarpa DC. The third sheet is J. Anil L. P poly-

nder the above name, as far as citations go, are thus included 
both the fairly distinctive ice he forms of J. tinctoria, the 
southern or Madras form with pods longer and more slender, and 
also as a rule fewer in ra ‘Sek the northern or Bengal form. 
So far as specimens go, however, an iPaper of the Pro 
dromus Herbarium obligingly permitted by M. C. andolle, who, 
with M. A. de Candolle, has most kindly helped one of us in the 
examination, shows that a macrocarpa includes (1) a specimen of 
the cultivated form of I. suffruticosa (i.e. I. Anil B polyphyila DC.) 
marked ‘* Coronilla? Senegal, Sparma ann”; (2) a specimen of the 
wild form of I. suffruticosa, marked ‘‘ Envo ide Demerara, M. Parker”; 
(3) a specimen of J. caerulea Roxb. i.e. of the eastern form of I. ar- 
ticulata Gouan; and (4) a specimen of J. tinctoria Herb. Vahl, ie 
Guinea, collected by Thonning and presented by Sonder. This 1 
the northern or Bengal form of J. tinctoria, and is the only ipebthnke 
of I. shinies present in the Prodromus cover of I. tinctoria a macro- 
carpa, 
It may be as well in this sie i state what in our opinion the 
forms of J. tinctoria are. There are three o a em :— 
1. The wild form, apparently u aie nown to Linneus or De Can 
dolle. This is the plant first discovered $y Kotschy, ral charae- 
terized as I. Anil L. var. orthocarpa by Schimper in

form bas frequently been collected in Africa; it is in- 
tereiting to find that the African Continent, and not, as has usually 
been 3 some portion of South-eastern Asia, is probably the 
—— home of I. tinctoria. This cc though exceedingly rare 
n India, is not there wholly unknown; specimens agreeing with 
the African plant have been sollaeted i in Central Indi
