ILLUSTRATIONS OF INDIAN BOTANY.

211 clearly perceive the object of this last change, nor do I understand on what principle it is made, since it sets aside an older and well established generic name which seems quite uncalled for. The plant represented (plate 170) under the name of Tournefortia has long been imperfectly known, from a passing good figure in Burmann's Flora Indica, under the name of Heliotr opium. 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- gherries ; 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.
