Hello Shah,

At first glance it looks like Z. officinale but without watching it live it is hard to say precisely.

Zingiber zerumbet

The Photograph showing  Zingiber zerumbet, also known as shampoo ginger or pinecone ginger, is a vigorous species of the ginger family with leafy stems growing to about 1.2 m tall. It is found in many tropical countries. 

Botanical name :Zingiber zerumbet , belong to family Zingiberaceae 

The leaves and leaf stalks, which are also fragrant, were used in baking in the imu, underground oven, to enhance the flavor of pork and fish as they cooked. Traditionally, the aromatic underground rhizomes were sliced, dried, and pounded to a powder, then added to the folds of stored kapa (tapa) cloth.

It is medicinally important  

Thank you so much Jay, Haroon and Varsa. special thanks to Varsha for details answer. Is this species near to Z. spectabile? 

Shah, If you go to Pubmed and get the ITS1 and ITS2 and 5.8S sequences, for each species, you can than download a software its free called Mega, and work out how close the various sequences are, let me know if you need more help. 

Haroon

In Malaysia, we call it as Lempoyang (Zingiber zerumbet Smith.)

On first glance I too thought of Zingiber zerumbet  as this species is quite commonly grown in the gardens in Thailand.  However, to have a very precise classification, it best to carry the specimen to the nearest Botanical survey people who are dealing with such identification issues on a daily basis. 

yes. It is Z. zerumbet.

Thank you Haroon, Shahril, Joy and Partho.

Dear Haroon, I never use  ITS1 and ITS2 and 5.8S sequences. Please let me know details. 

I agree with Zingiber zerumbet . Have a wide distribution in India, Sri Lanka and Malesia

Thanks Narayanan
