EXPLANATION OF PLATE 134.
This plate contains analyses, similar to the preceding,
of 8 genera, representing the Tribes of Compositae
found in India. As the parts shown in each are the
same as those named above, it does not seem necessary
to go over each. I shall therefore simply name the
genera, referring the reader to the preceding generic
characters for further explanations.
1. Vernoneaceje. Yemonea cinerea.
2. Eufatoriaceæ. Agératum conyzoides.
3. A steroideæ. Siegesbeckia orientalis.
4. Senecionideæ. Notonia grandiflora.
5. Cynareæ. Tricholepis Candolliana. [An unde
scribed species.]
5. Cynareæ. Amberboa Indica.
6. Müticiaceæ. Dicoma lanugenosa.
7. Cichoraceæ. Picris hieracioides y. Indica.
