do I understand

70) under the name of Tournefortia 



Heliotropl 



Zeylanicum^ under which I published it in my Icones. More intimate acquaintance with the 

 order having enabled me to detect my mistake, I take advantage of this opportunity to pub- 

 lish a new and more correct figure under its proper generic appellation. It is, in many parts 

 of India, a common annual growing in cultivated fields, flowering during the rainy and cool 

 seasons, and is, I believe, the only species of the genus found on the plains of Southern India ; 

 there is another common about Point de Galle in Ceylon, and a third I found on the Neil- 

 gherrles; a fourth, T. Heyneana, is described, perhaps from Mysore^ and three or four are 

 natives of the more Northern provinces. A genus so rare, merits being better know than^ it 

 has hitherto been in India. The species of Ehretia, here given, is not a native of the penin- 

 sula, but as no figure of it has yet appeared in any Indian botanical work, and having authentic 

 specimens, I preferred it to better known species, while it has the advantage of furnishing the 

 link connecting EhretiecE and Cordiece through its sub-corymbose^ scarcely gyrate inflorescence.
