416 SYNGENESIA AEQUALIS, Ageratum. 
four or five inches long, Flowers very numerous, rather 
small, of a pale purple, terminating the plant in numerous, 
sub-globular umbellets, the whole forming a large, irregular, 
compound corymb, Calyx, scales lanceolate, pointed. Seeds 
black, with hispid angles. Pappus of five scales, with 
broader, cordate, serrate bases, ending in long subulate 
points, resembling the partial calyx of the orders Polygamia 
Segregata, Receptacle naked, hemispheric, 
2. A. aquaticum, Roxb. 
Annual. Leaves opposite, lanceolate, serrate, Flowers sub- 
umbelled. Stiyma clubbed, twice the length of the florets. 
Beng. Bura kesutee. 
A native of the borders of rivulets among the Circar moun- 
tains. Flowering time the cold season, i 
Siem annual, somewhat succulent, below resting on the 
ground, above erect, round, very slightly hairy, from two to 
four feet long. Leaves opposite, decussated, petioled, bori- 
zontal, broad-lanceolate, serrate,smooth,somewhat succulent; 
from four to six inches long. Flowers terminal, forming an 
irregular, thin umbel, white. Calyx from twenty to thirty- 
leaved, equal, Coro/, outside of the mouth woolly. Stamens 
within the tube. Stigmas twice as long as the corollets, 
erect, clubbed, white, they are a good and conspicuous mark. 
Seeds crowned with a glandular margin, from which issue 
three, four or five headed, pedicelled glands. Receptacle 
Note, By the structure of the stigmas, they being when 
full grown, far above the anthers, and the flowers all erect, 
it might be concluded the pollen could not reach them, bat 
I could observe clearly that the anthers are ripe, and barst 
while the stigmas are of an equal length with and closely em- 
braced by them, the stigmas continue to grow and carry with 
them a large portion of the dust; this wonderful economy ! 
have frequently observed in a number of plants which at least 
helps to invalidate one of the old anti-sexualists’ arguments.
