tree or shrub from Hooghly 14/12/12 sk:

Found this tree or shrub beside a road in a dense thicket, it was not possible to ascertain if it was a tree or not.
Species : UNKNOWN
H & H : tree or shrub, leaves alternate, one or two branches bear spine
Date : 14/12/12, 1.30 p.m.
Place : Hooghly


Thank you Sir, this is a tree, found another one, about 20 ft high.


This is a member of Euphorbiaceae (Flowers are yet to open). I think once temperature increase they will start flowering. Please check Trewia?


Thank you very much …,

Attaching new pictures, recorded today.


It is neither Trewia nor Mallotus tetracoccus.

I think this is a straggling species. I think it could be a species of Crotton


Though this plant in this thread looks like straggling shrub, i think, the main trunk might have been cut by someone. I found another one which was a small tree.
FoC and FoP inform that leaves of Mallotus are “alternate or opposite”. and also in the pdf found at – https://openaccess.leidenuniv.nl/bitstream/handle/1887/12383/Kulju_thesis_4_Cp3.pdf?sequence=12.



It is Mallotus repandus. 


Thank you very much Sir.
But, the leaf pictures of Mallotus repandus (Willd.) Müll.Arg., found in the FoC, looks different to me –
Moreover flowering time also differs, that can also be found in the description of Rottlera dicocca Roxb. in the Flora Indica.


I request you to follow the undermentioned steps for satisfactory identification of your photographs which is without any voucher specimen (and you are not satisfied with the identification): 
First, please try to learn the range of variation of a widespread species. Just forget about the flowering and fruiting time. Do you think that it is a new species as it is differing from Flora of China. Then just publish it. 
Second, instead of looking at Flora of China, please consult the following publication: The family Euphorbiaceae in India by N.P.Balakrishnan and T. Chakrabarty, published in 2007 by Bishen Singh Mahendra Pal Singh, Dehra Dun. 
Third, please collect a specimen of your object and preserve it. Next, visit Central National Herbarium, Howrah one day and compare your specimen with the specimens of Mallotus repandus. 
I hope, you will get the identity of your photographs. Please remember that photographic identification is never authentic.


If it is between these two species you can easily decide from this::
Mallotus repandus: Climbing shrubs; stipules triangular, ca. 1 mm; petiole 1.5-6 cm; leaf blade 3.5-10 × 2.5-7 cm, papery, base broadly cuneate; male inflorescences terminal with branches few or absent; bracts subulate, ca. 1.5 mm. Male flowers 2-5-fascicled;female inflorescences 5-8 cm; bracts ca. 2 mm. sepals 2-3 mm; ovary 2- or 3-locular; Fruiting pedicel 8-12 mm; capsule yellowish-brownish tomentulose, scattered glandular-scaly.
Mallotus tetracoccus: Trees 5-15 m tall; stipules ovate-triangular, 1.5-3 mm; petiole 6-15 cm; leaf blade 10-25 × 9-20 cm, base obtuse or truncate; male inflorescences terminal, branched; bracts triangular, 1-1.5 mm; male flowers 3-9-fascicled; female inflorescences paniculate, 9-14 cm, tomentose; bracts 3-5 mm; sepals 3-4 mm; often 4-loculed; fruiting pedicel 5 mm long; capsule depressed globose, gray tomentose and densely shortly softly spiny, spines stellate-pubescent.


I have recorded more pictures today. But, i am not sure of its stipules, attaching pictures herewith.
However, i give my explanation here, more elaborately –
“Bengal Plants” describes four Mallotus species – 1) M. roxburghianus Muell.-Arg. 2) M. albus Muell.-Arg. 3) M. repandus Muell.-Arg. 4) M. philippinensis Muell.-Arg.
Our group has M. philippinensis Muell.-Arg. –
1) Mallotus repandus Muell.-Arg.; F. B. I. 5. 442. Rottlera dicocca F. I. iii. 829.
2) Mallotus albus Muell.-Arg.; F. B. I. v. 429. E. D. M. 66. Rottlera alba F. I. iii. 829. R. tetracocca F. I. iii. 826.
 
The above info can be found in – link
Entry in F. I. iii. 829. reads –
1) R. dicocca R.
Scandent. Leaves round-cordate, alternate three nerved. Racemes terminal and axillary. Capsules dicoccus. …… A native of various parts of India. It is a weak though large, sub-scandent shrub. Flowering time the hot season; the seed ripens in the rainy season.
2) R. alba R.
Arboreous. Leaves alternate, long-petioled, cordate, somewhat peltate, and slightly scollop-dentate, hoary underneath. Panicles terminal. Capsules villous, armed with villous filaments. A native of Prince of Wales’ Island. It flowers in the Botanic garden during the rains and the beginning of the cool season.
The info can be seen at – link.
Entry in F. I. iii. 826. reads –
R. tetracocca R.
Young shoots ferruginous. Leaves long-petioled, cordate, rarely lobate, acuminate, hoary underneath. Panicle terminal. Capsules hoary, papillose, tetracoccus…. It flowers in April and May; and seeds ripen in August.
…… leaves alternate, long-petioled, cordate, tending to be peltate in young plants…. stipules minute ….Panicles terminal… composed of several simple branches……
More can be seen/read at – link 1 and link 2 
In connection to above i searched and found leaves are similar to that of Mallotus tetracoccus of FoC, while flowering season matches with Rottlera alba R. and The Plant List equates it with Mallotus paniculatus var. paniculatus. 
There is Mallotus paniculatus in FoC – http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200012592 and pictures of Mallotus paniculatus var. paniculatus can be found at – http://www.flickr.com/photos/mingiweng/3914991751/ and at – http://www.flickr.com/photos/mingiweng/3915745822/, if the claimed ID is correct in those flickr pics. 
The leaf size in the attached pictures are not exhaustive, bigger and smaller leaves can also be found.
Nevertheless, i fully subscribe to experts’ views.

Mallotus sp. Hooghly 22-01-13 sk1:  I think it is rather a big shrub, because i couldn’t find its tree like trunk. The overall appearance is like the one in my earlier post (https://groups.google.com/d/topic/indiantreepix/a3uQPRPzQP0/discussion), but :-

  • inflorescence is much smaller
  • 80% leaves are shallowly cordate
  • not sure if these leaves can be called slightly peltate
  • i selected one of the biggest leaves and with longest petiole to show leaf size
  • couldn’t find any stipule
Species : UNKNOWN
H & H : about 20 ft or more tall; in a village thicket; longest inflorescence seems to be about 5 inches long or smaller
Date : 22/1/13
Place : Hooghly


i think this plant is Rottlera dicocca of Flora Indica.

Thanks for detailed, beautiful pictures and web-link …


Thank you …, according to FI this is a scandent shrub with long branches. The trunk in the backdrop of the 1st and 5th pics are of another tree, might be of a Mahogany.
