12022015 - Tree for ID - 02

[Ajit Ampalakkad]

Hi,

Kindly help me ID this tree. This was seen in Nandi hills, bangalore on 12th Feb 2015.  One ID suggested is Mallotus nudiflorus (Trewia nudiflora). By the look of the bark, it does not have the characteristic grey smooth bark seen in T. nudiflora. Hence i am having a doubt. 

Please suggest and help.

Available data on the characters of the bark in Euphorbiaceae is insufficient for species demarcations.  Hence it is not possible to identify the species on this character.  However, the other morphological features point to Trevia (not Trewia) nudiflora var. nudiflora, recently treated to be Mallotus nudiflorus.

Thanks Tapas ji. Based on your input as well, for the time, we can keep it at Mallotus nudiflorus.

Trewia versus Trevia seems an interesting point. Can you elaborate on that? Everywhere Mallotus nudiflorus's syn is used as Trewia including Flowersofindia website. So does it require a correction?

Thank you very much.  Here is an extract from Flora of India Volume 23. I hope that these points will be helpful is getting the answer of your query.  We have maintained the name Trevia nudiflora here.  If you so wish, there is no harm in calling it a Mallotus.

10. Trevia L.

Monotypic, from India to China and Indonesia.

Note.  Based on molecular studies, Kulju, Sierra & Welzen (Blumea 52: 124. 2007) merge this genus with Mallotus.  The generic name Trevia L. (1753) has priority over Mallotus Lour. (1790).  Kulju & Welzen (Taxon 57: 1358. 2008), has made a formal proposal for conservation of the generic name Mallotus against Trevia and it is still pending a decision.

The original spelling used by Linnaeus (Sp. Pl. ed. 1, 2: 1193. 1753) is ‘Trevia’, but later he inconsistently used both ‘Trevia’ and ‘Trewia’.  All subsequent authors have adopted the spelling ‘Trewia’.  However, Art. 13.4 of the present Code (2006) gives protection to the original spelling given in Species Plantarum, ed. 1 (1753) and therefore ‘Trevia’ cannot be altered.

Literature.  KULJU, K. K. M., S. E. C. SIERRA & P. C. VAN WELZEN (2007). Re-shaping Mallotus (Part 2): Inclusion of Neotrewia, Octospermum and Trewia in Mallotus s. s. (Euphorbiaceae s. s.). Blumea 52: 115 – 136.  SUSILA RANI, S. R. M. & N. P. BALAKRISHNAN (1998).  Notes on Trewia nudiflora L. (Euphorbiaceae) and its varieties.  J. Econ. Taxon. Bot. 22: 345 - 352, ff. 1 - 4.

Trevia nudiflora L., Sp. Pl. 1193. 1753; Müll.Arg. in DC., Prodr. 15(2): 953. 1866; Hook.f., Fl. Brit. India 423. 1887.  Mallotus nudiflorus (L.) Kulju & Welzen, Blumea 52: 124. 2007.
