Gurcharan Ji,

Thanks for the id.

Aarti ji and Gurcharan ji, you both are correct in a way or other!

It is Umbellularia californica (californian bay laurel) often mistaken for and/or adulterated to the Mediterranean or Sweet bay laurel, Laurus nobilis. This plant (U. californica) is used in the same was as L. nobilis but it causes severe headache in some people who are allergic to it. Umbellulone is the compound responsible for this allergic action present in the leaves of U. californica.

Please check this article for more details http://pubs.acs.org/doi/abs/10.1021/jf4052682

Thanks Vijayasankar ji for alert. I now remember these fruits when we visited Shasta Caverns in 2008. I think I have both. I am uploading both for your validation. I have checked Japson Flora. Both are recorded from California

Vijayasankar Ji, Gurcharan Ji,

Thanks a lot for the id and additional information.

Since returning, I have been trying to find ids on Google search.

Thats how I had found the id to be Umbellularia californica, Californian Bay Laurel of Lauraceae.

My observation was that the fruits were slightly bigger than those of Laurus nobilis.

Thanks for the correction Vijayasankar Ji.

Regards,

Aarti

Gurcharan ji, I think the 2nd picture is U. californica. Other two pictures are correctly identified. As you might know, U. californica is native to California, Oregon etc. whereas, L. nobilis is a Mediterranean species and occurs only under cultivation in the USA.

Aarti ji, I really appreciate your identification of this (and several other) species and also your keen observations. These plants can confuse even trained experts. Great work!
In our paper, we have compared both the species by their chemistry and leaf anatomy.

 

Regards 

Vijayasankar

Nice article Vijayasankar ji. Has it been tried in India to retard the spread of Dengue and Chikungunya?

Vijayasankar Ji,

Really appreciate your kind words for me.

I just enjoy observing nature wherever I go.

Time was too short with a family wedding, which was the main purpose of our visit.

All California plants & trees are under my scanner and I could identify quite a few of them.

Will be posting them as time permits.

Wishing you and your family a Happy Diwali!

Regards,

Aarti

 

[Vijayasankar]

Thanks Aarti ji for the wishes. I wish you all a wonderful Diwali, too.

Badri ji, thanks. As I have mentioned earlier, Umbellularia californica is native to California and its adjoining and is not present or grown in India. However, its essential oil can be used in controlling mosquito when it is proved to be safe to use.

 

Regards 

Vijayasankar

Vijayasankar ji

I request you to have a relook at the second image. I have cropped fruits portion from original so that you can have a look again. I feel the fruits are too small and too many for Umbellularia californica.

Gurcharan Ji,

I agree with you.

When I was searching the id for my tree, I found single fruit & larger in size in Umbellularia californica, which matched with my pictures.

This is how I had come to the id as being closest to my pictures.

Regards,

Aarti 

[Vijayasankar]

Thanks Gurcharan ji. My bad...it is not Umbellularia, but I am pretty sure it is also not Laurus nobilis.
Looking at the fruits, I even doubt if it is a Lauraceae member. I hope you have taken more pictures, also of flowers.

Gurcharan Ji, Garg Ji, Vijayasankar Ji,

Somehow the buds in my pictures are not matching with either of the names suggested.

This could be something else?

Can we have a relook?

Regards,

Aarti
