300 Notes on Indian Botany. 



scarcely dilated : anthers very slenderly caudate at the base : 

 acheenia terete : pappus 1 -series, bristles capillary, scarcely 

 rough. Herbaceous or suffruticose plants with panicled or 

 loosely corymbose inflorescence: involucrum imbricated many 

 series, scales linear acuminated : receptacle flat, quite naked, 

 or sometimes hairy : flowers yellow or purple. 



31. Pluchea, (Cass. D. C. 5-449). Capitula heteroga- 

 mous : flowers of the circumference many series female, trun- 

 cated or 2-3-toothed ; central ones few male, or imperfectly 

 hermaphrodite, 5-toothed : anthers bicaudate at the base : 

 achaenia erostrate, cylindrical or furrow- angled : pappus 

 1 -series, bristles filiform, scarcely rough. Herbaceous or suf- 

 fruticose ; leaves alternate, often glanduloso-pubescent : capi- 

 tula corymbose pedicelled : involucrum many series imbrica- 

 ted : receptacle naked or hairy, fimbrillate : flowers yellow. 

 [This genus appears scarcely distinct from the preceding. 

 D. C. remarks " a Conyza et Blumea antheris caudatis diver- 

 sum,' 5 a very slender difference.] 



32. Monenteles, (Labill. D. C. 5-455). Capitulum many 

 flowered ; marginal 2-3-series female, scarcely dentate ; of 

 the disk 1-5-hermaphrodite or male, 5-toothed, subglandulose 

 without : anthers of the disk with subulate spurs : achsenia 

 oblong subcom pressed sparingly villous : pappus 1 -series, 

 bristles filiform, connected at the base. Ramous herbs, leaves 

 decurrent forming wings to the stems : capitula sessile, fasci- 

 culed in the axils of the floral leaves forming spikes : involu- 

 crum 2-series, persistent, about equal, not imbricated ; recep- 

 tacle flat, narrow. 



33. Epaltes, (Cass. D. C. 5-461). Capitula heteroga- 

 mous, flowers of the circumference many series, female ; of the 

 disk sterile : anthers included : styles of the disk scarcely ex- 

 serted, undivided : achaenia of the ray obovate, subangled,
