 which examples are taken are, however, noted, and their leading 

 features stated.]

 anthers sagittate at the base ; style-branches subulate, hairy ; leaves 

 very often alternate; corolla never yellow; pappus often setose or 

 paleaceous. 



* Subtribe JEkivernonieos. — Heads distinct, many _ flowered. 

 Examples : Oentratherum, Vernonia. The examples obtainable not

 iemma. 



Subtribe Ageratecs. — Anther-tip appendiculate ; achenes 5-angled.

Of the genera mentioned the first will be found on very wet

 both garden and field ; the last will be found in garden culture, and 

 possessing more or less beauty and supposed medicinal virtues.

Subtribe PlucJieinecB. — Heads androgynous. Involucral bracts 

 dry or herbaceous, rarely subscarious. Eeceptacle naked. Style- 

 arms of the hermaphrodite flowers filiform, not truncate, or style of

 More or less weedy plants, seldom of much beauty ; this is especially 

 the case with those species of which examples wiU be obtainable.

 Involucral bracts scarious, usually hyaline, or the inner radiating.
