It (Ageratum houstonianum) has larger and robust plants and flowerheads with more florets than A.conyzoides.
 
In A conyzoides plants and phyllaries are not that densely hairy, and heads are smaller and more spreading
 
Thicker cordate leaves and longer hairs especially on involucre bracts are clearly seen in Ageratum houstonianum. 
 
Ageratum L. genus is represented in India by two species- A. conyzoides and A.houstonianum.
These closely related pantropica weed species can be differentiated as follows:
Involucral bracts linear, sharply acute-acuminate, sparsely hairy; Corolla of the florets 1.5mm long, shorter than awned pappus scale.... A. conyzoides L.
Involucral bracts linear setaceous, densely hairy; Corolla of the florets 2.5mm long, as long as or longer than awned pappus .... A. haustonianum Mill.

 

Ageratum conyzoides (Billygoat-weed, Chick weed, Goatweed, Whiteweed; Ageratum conycoides L., Ageratum obtusifolium Lam., Cacalia mentrasto Vell.) is native to Tropical America, especially Brazil.  
Herb 0.5–1 m. high, with ovate leaves 2–6 cm long, and flowers are white to mauve.[1]  
Ingesting A. conyzoides can cause liver lesions and tumors.[4][5] There was a mass poisoning incident in Ethiopia as a result of contamination of grain with A. conyzoides.[6] The plant contains the pyrrolizidine alkaloids lycopsamine and echinatine. 
A. conyzoides is prone to becoming a rampant environmental weed when grown outside of its natural range. It is an invasive weed in Africa, Australia, Southeast Asia and the USA.[7][8] It is considered a moderate weed of rice cultivation in Asia.[9]

Ageratum L. genus is represented in India by two species- A. conyzoides and A.houstonianum. Both of these species are not native in India but are invasive alien species originating in Tropical America. In Uttarakhand these reach up to 2000m altitude in the Himalaya.
These closely related pantropica weed species can be differentiated as follows:
Involucral bracts linear, sharply acute-acuminate, sparsely hairy; Corolla of the florets 1.5mm long, shorter than awned pappus scale.... A.conyzoides L.
Involucral bracts linear setaceous, densely hairy; Corolla of the florets 2.5mm long, as long as or longer than awned pappus .... A.haustonianum Mill.

Ageratum conyzoides…
Want to confirm... Are we sure this is not Vernonia cinerea?
Also important because V. cinerea is native to Africa whereas A. conyzoides is native to the Americas.
… said is correct; am also agree with them, no doubt in that. now it's very common at marshy and aquatic areas in our country( we have also, Andhra Pradesh)

It is my pleasure to share few images of Ageratum houstonianum  (Asteraceae) one of the virulent colonisers of wastelands. Similar to its much more virulent cousin, A.conyzoides . As per the efi thread A.houstonianum is larger and robust than A.conyzoides having more florets in the flower heads, thicker leaves and longer hairs. 

Habit: Herb 

Habitat: Waste lands 

Sighting: Chikmagalur, Karnataka, about 1000 msl 

Date: 06-06-2014 and 13-08-2014


A reply from another thread:

"... Ageratum is Ageratum conyzoides only a variant but the remaining two are A.haustonianum"
