Manihot carthaginensis subsp. glaziovii (Müll.Arg.) Allem, Novon 11: 160 2001. (Syn: Manihot glaziovii Müll.Arg.);
.      Request Tree ID 55 – Bangalore – RA: Looks like Euphorbiaceae member. Possibly related to Jatropha. just guess, can it be Hevea species I also feel it could be H.brasiliensis, commercial Rubber tree. Not Hevea brisiliensis please, which has trifoliate leaves, whereas this one has simply deeply lobed leaves. Also fruits are weekly tilobed in Hevea, not here. Identity of the ZZ Unknown 055 Tree is Manihot glaziovii Yes it is Manihot glaziovii of Euphorbiaceae family, a close relative of tapioca. Manihot glaziovii is a glabrous shrub or tree to 6 m high, occasionally taller (10-20 m), often with several weak branches from near the base.
Bark papery, peeling, dark reddish brown. Young shoots glaucous.
Leaves deeply palmipartite, 3-5 lobed, peltate. Cordate, membranous-chartaceous, lobes broadly ovate to obovate, (4-)7-12(-15) cm long, (2-)4-8(-10) wide, entire. Green above, glaucous beneath, petiole to 25 cm long, often tinged reddish. Stipules lanceolate 5 mm long, entire, decidous.
Inflorescence paniculate, to 12 cm long, bracts resembling the stipules. Male flowers 7-9 mm long, female flowers 0.8-1.4 cm long extending to 2-3 cm in fruit.
Fruit globose 1.9-2 cm by 1.9-2.2 cm, smooth, muricate-tuberculate, endocarp woody.

Alt.: 120 m asl Could this be Manihot glaviozii of Euphorbiaceae? Yes …, This is Ceara rubber tree (Manihot glaziovii). It is now naturalized in Kerala and Tamil Nadu and also occasionally seen in the Andamans though its cultivation is now discontinued. Yes, It is Manihot glaziovii Thank you … for confirming the ID and for the details. .
Yes, … We have this in our site as Manihot carthaginensis subsp. glaziovii (Cultivated)
I would like to share photos of the bivalved cocci fallen on ground and the seeds released on the ground of the Manihot carthaginensis tree at Agara Lake on 4 JAN 2022. The green fruits were observed mid August of 2021. . How Manihot carthaginensis subsp. glaziovii came in India: Does anyone have any idea?

Greetings, I am in Singapore. Here, Manihot carthaginensis subsp. glaziovii (locally known as tree tapioca or elephant tapioca) was cultivated in plantations in the 1800’s for latex for making rubber. It was later replaced in this role by another member of the Euphorbiaceae, the Para rubber tree Hevea brisiliensis, once the British had smuggled seeds out of Brazil. I have not yet found out when or where or by whom Manihot carthaginensis subsp. glaziovii was introduced to the East Indies. Does anyone here know? When was it introduced to India? Who brought it there and from where? Was it by the British or Portuguese or someone else?
