Holigarna evergrreen sp. : 5 posts by 2 authors. Attachments (6)
The beautiful evergreen species seen by us for the first time. The leaves have 2 to 4 spurs near the petioles. Seen at various places at Kulgi, Anashi and Ulvi WLS Karnataka last week of April, ’10. Most probably it is H. grahami (Wt.) Kurz. would appreciate validation of the same.
I think this is Holigarna grahamii from the family Anacardiaceae (Cashernut family)
Thanks for confirming the ID … The spelling in Dr. Almeida’s flora is with one ‘ i ‘ only for grahami. What to follow?
Kidly give a search in Google and see all the plant bases and Herbarium is using “ii” hence i wrote it eben even in Flora of Madras Presidency
Ok … Thanks for your efforts, shall correct it to H. grahamii.
Tree with very large leaves : 2 posts by 2 authors.
I saw many such trees with very large leaves in Amboli as well as in Amba ghat area. It was not flowering
Yes … the tree is Holigarna grahamii. I can see the spurs too and the distinct triangular shape of the leaves from the middle. Dr. Almeida’s flora does mention distribution in Amboli, Konkan, mira hills near Pen, Khandal, Ramghat, Radhanagri.
The tree has resin and leaves can cause itching if touched.

Kindly identify this Holigarna specimen. Is this Holigarna arnottiana or Holigarna ferruginea…???
Habitat: Semi-evergreen forest
Sighting: Balehonnur, Chikmagalur, Karnataka, about 1100 msl
Leaves have to be more than 30 cm long, rusty pubescent beneath and the fruit has to be less than 1 cm long for it to be H ferruginea. I can barely see underside of leaves to call it ferruginea. You need to confirm other features.
Thanks … for the feedback. How about H.arnottiana…??
I strongly believe that the uploaded images are that of a specimen belonging to the genus Holigarna. The Digita Flora of Karnataka describes five species that are known to occur in Karnataka...H.arnottiana, H.ferruginea, H.grahamii, H.nigra and H.beddomei….. If H.arnottiana and H.arnottiana are ruled out the options narrow down to the remaining three H.grahamii, H. nigra and H.beddomei….! No images of are avaliable in that site for H.beddomei . A detailed floral desciption is provided for H.grahamii . But I am not able to decipher this….! Moreover, H.grahamii is known to occur in the region where the instant specimen was found…! Would the experts kindly examine…? I understand that it is difficult to identify a specimen by images alone,but I am left with no options except the images that I have uploaded…!
Ref: Description for H.grahamii for ready reference.
Keeping my fingers crossed…!!!
It is needless to emphasize that here comes the need for collection and preparation of herbarium specimens!
On perusal of references & posts at Holigarna grahamii , I agree with you. But I am not sure
Id can be confirmed only from specimens of leaf and fruit. These do not show in the pictures. Till then it can be only guessed.
Thanks … I will try to get some pics of leaves and fruits as well when I visit next. Thanks for your feed back.
It look like Holigarna grahamii
