 alveolate : flowers regular 5-cleft, purplish. 



5. Monosis, (D. C. 5-77). Capitula 1-flowered : achaenia 

 glabrous terete : pappus 2-3-series, bristles rigid scabrous. 

 Arboreous or suffruticose, leaves alternate : panicles naked, 

 the apices of the branchlets bearing numerous subumbellate 

 sessile capitulae : scales of the involucrum imbricated, ob-

 Wightiana is a considerable tree, with large obovate leaves, 

 traversed by thick transverse veins like those of a Dillenia."] 



Div. II. Elephantopeae. Anthers ecaudate: involucrum 

 compressed : scales alternately conduplicate, 



6. Elephantopus, (Cass. Lin. D. C. 5-85). Capitula of 

 several (3-5, usually 4) equal flowers, densely congested into a 

 glomerulus, enclosed by leaves : achaenia slightly compressed, 

 many ribbed, pilose: pappus 1 -series, some of the bristles 

 dilated at the base. Perennial pilose herbs : alternate, with 

 leaves and terminal ; glomerulus involucrum compressed, 

 scales in a double series, alternately flat and conduplicate : 

 rachis naked : corolla palmate, limb 5-cleft, one of the fissures 

 deeper.

Sub-tribe. Eupatorie^e. Capitula homogamous,

 late. 



7. Ageratum, (Lin. D. C. 5-108). Capitula many 

 flowered : achaenia somewhat 5-angled, attenuated at the base : 

 pappus 5-10, free paleaceous scales, aristato-acuminate, or
