Croton aromaticus


Is Croton laccifer L. a synonym for C.aromaticus?


Yes, Croton laccifer L. is a synonym of C. aromaticus L.


Links available at net on search seems at variance from your observations:

The Plant List MMPND India Biodiversity Portal 


We combined Croton laccifer L. with C. aromaticus L. perhaps in 1981.

As the dates of publication of both the species are same, we chose the name Croton aromaticus for the combined species.

Croton ¿ malabaricus ?

Dear friends, please help with ID.
Moderate sized tree bearing male and female flowers spikes; fallen male flower measuring about 3 – 4 mm across.
Found along NH 49 near Chinnakanal, Munnar.
At facebook, suggested ID to genus level is Croton; could it be C. malabaricus ?

Yes please. Excellent photos. It is an endemic species.


The photos look like an admixture. The last photos in particular with cordate leaf base belong to something very different. Croton malabaricus never has such cordate leaf base.


Thank you very much … for re-validating the ID (of not being C. malabaricus).

The last picture shows mix of plants; I should have specifically mentioned that it is for showing the tree trunk. The branches, leaves could be a mix of adjacent tree(s).
Since I do not find presence of glands at the junction of lamina and petiole, I am hesitant to think of C. laccifer OR C. aromaticus.

Hoping we reach an ID with posted photos.


the plant is identified C.lacciferus


Many thanks … for resurfacing the query.

Thanks very very much Ramachandran ji for the ID.

I am keen to know the author citation for Croton lacciferus
… whether
1) Croton lacciferus L. … synonym of Croton aromaticus L.

2) Croton lacciferus Blanco … synonym of Macaranga tanarius (L.) Müll.Arg.


I could find the following only (No Croton lacciferus L.):
Croton lacciferus Blanco

I had seen this page in A Dictionary of the Economic Products of India, Volume 2.


Relevant words are obscured on seeing.


Not sure I understood your point … Attaching a screenshot of what I see on the page …


Thanks, … But I think this is a 19th century book.


Agreed … I found in this text … Croton lacciferus L. as synonym of Croton aromaticus L.
Croton lacciferus Blanco is synonym of Macaranga tanarius (L.) Müll.Arg. at The Plants List … does not seem to be distributed in India, and has peltate leaves.

Croton lacciferus L. (= Croton aromaticus L.) has 2 pair of glands at the junction of lamina and petiole beneath, which I cannot see in my posted pictures.


…, please let me correct myself – that the poor quality of photos may not be showing the glands clearly.
