Euphorbia tithymaloides
is native to tropical and subtropical North America and Central America.
It prefers soil that is sandy, well-drained, and nutrient-rich, particularly with higher concentrations of boron, copper, iron, manganese, molybdenum, and zinc.[9][10] It is relatively intolerant of high soil salinity levels, but exhibits saline tolerance if well fertilized.[10] The plant tends to be taller and have more biomass if it is well-watered.[10] The plant requires a sunny area to grow in.[9]
The shrub can grow to 6 to 8 feet (1.8 to 2.4 m) in height and generally is about 18 to 24 inches (46 to 61 cm) in width.[11] The leaf is a simple angiosperm leaf, arranged oppositely on the stem.[2][11] Each leaf is sessile (attaching directly to the plant), and about 1.4 to 3 inches (3.6 to 7.6 cm) in length.[2][11] The leaves are glabrous (smooth) and acuminate in shape, with entire (smooth) edges.[2][11] The veins in the leaves are pinnate.[2][11]
The plant terminates in a dichotomous cyme, with a peduncle supporting each flower.[2][11] The floral leaves are bifid (split in two parts) and ovate, while the involucral bracts are bright red, irregularly acuminate in shape (e.g., like a slipper), and about 0.043 to 0.051 inches (1.1 to 1.3 mm) in length with a long, thin tube.[2][11] The flower is void of scent.[12] The male pedicel is hairy, while the female is glabrous.[11] The seed pod is about 0.30 inches (7.6 mm) long and 0.35 inches (8.9 mm) wide, and ovoid in shape (with truncated ends).[11] The plant generally flowers in mid-spring.[2] 
The roots, stems, and leaves of the plant are known to be toxic.[4][16]

request for identification - 03012011PC3: Please identify this plant. Is it a member of Euphorbiaceae?
Cultivated, photographed on side of Lodi road, New Delhi.
Same plant has the green as well as variegated branches. Only a narrow region along the leaf margin is colourless. When sectioned the colourless part had cells without or very few green chloroplasts while the green parts of some leaves have green chloroplasts in all the mesophyll cells, some other leaves have green chloroplasts only in the middle region with the pallisade and lower spongy parenchyma layers devoid of them and some other leaves have green chloroplasts in all the cells except the pallisade layers.
Any idea how the colourless cells form only at the margins?

- This plant is commonly known as devils backbone .. I really dont know why?
- Its called backbone may be just because of its structure which is zigzag and similar to our backbone when we curve down and devil's may be because it is poisonous. But thats just a speculation.
- I have also heard it called as Jacob's Ladder.
- Jacob's ladder is actually a mythological ladder which leads to heaven. This may sound hilarious, but may be it is so poisonous that it will straight away lead you to heaven, hence it is named that way!!! and of course the stem is zigzag like a ladder.
- I do know that it is "non-browseable" so we had a line of these plants near the barbed wire fence thro which the goats used to try to eat the marigold plants at Alto-Chicalim in Goa (off Vasco.)
- Good, I knew it is poisonous.  I was planning to plant a cutting of the plant.
Euphorbiaceae: Pedilanthus tithymaloides. Euphorbiaceae
- Kindly also note as mentioned in .. post of the same plant yesterday, the current accepted name as per Kew Plant List is Euphorbia tithymaloides L.

Euphorbiaceae Week: Euphorbia tithymaloides from Delhi: Euphorbia tithymaloides L.,  Sp. pl. 1:453. 1753
syn: Pedilanthus tithymaloides (L.) Poit.
A succulent shrub with leaves often shedding in dry spell, commonly grown in Delhi along hedges and rockeries.

Euphorbia tithymaloides f. variegata from Delhi. This variegated form is some times grown in Delhi.
Extracting Nectar from an unlikely plant...: The Variegated Devil's backbone (Euphorbia tithymaloides or Pedilanthus tithymaloides)- this is a plant with a milky sap, originally from Central America . Whenever I used to see the tiny flowers on these plants growing at home I used to wonder whether they had any nectar in them. I was fairly sure that no bird would come near these flowers. But nature has her own ways and I was very surprised to see a purple sunbird extracting nectar from it... Lesson learnt :-) 
The Latin name of this plant Pedilanthus tithymaloides variegata means “slipper flower” or “foot-shaped flower,”
The Wikipedia tells me the following:
Common names in english: buck-thorn, cimora misha, Christmas Candle, Devil's Backbone,Fiddle Flower, ipecacuahana, Jacob's Ladder, Japanese Poinsettia, Jew's Slipper,Jewbush, Milk-Hedge, Myrtle-Leaved Spurge, Padus-Leaved Clipper Plant, Red Slipper Spurge, Redbird Cactus, Redbird Flower, Slipper Flower, Slipper Plant, Slipper Spurge,timora misha, and Zig-Zag Plant
Other languages: gin-ryu(Japan); pokok lipan and penawar lipan (Indonesia); airi, baire, and agia (India); aperejo (Yoruba); sapatinho do diablo (Brazil); itamo real (Puerto Rico); pantoufle (France); and zapatilla del diablo (Mexico).
p.s. A google image search for 'plants with milky sap' finally led me to the names of this plant...

Pedilanthus tithymaloides for me too
Hooghly Today : Euphorbia tithymaloides L.:  This seems to be the Pedilanthus tithymaloides Poit. of Bengal Plants and F. B. I. [Euphorbia tithymaloides L. of GRIN and The Plant List; Pedilanthus tithymaloides (Linnaeus) Poiteau of FoC], a common hedge plant in rural home-yard, but with very few flowers, and that too can only be seen on one or two individuals.
Nice details ..., I support your ID.
Initially i was hesitant, for google gave me many flowered plants, but then those are cultivated for ornamental.
I know it as devil's back bone and it never flowers in a pot in the balcony.
In west Bengal driving around I have seen it growing wild near ponds...
It is a succulent, yet by the ponds nature bothered me
today googling for the poper name I got to know that it grows well and tall if it get enough water, reading the wiki essay. 

I also noticed that it never flowers, both in the wild or when it is used in hedges. I see them in many places, near my house also, but i know where i could find only one or two flowering ones, near my school.
Flowering is seasonal. Very common in Chennai gardens as hedge / border plant.

Requesting to please ID this plant captured at Rajgad near Pune in Sep 2014.
Not sure whether this was cultivated or wild because this was at the base of the mountain near a house.
It is Euphorbia tithymaloides L. (= Pedilanthus tithymaloides (L.) Poit), ornamental herb 
Thank you ... for the ID..
I thought as much but was confused because of the dark green colour of the leaves.
The plants in Mumbai here are very light green and white, I guess, variegated.
Can this be a growing wild there?

This perennial succulent herb resembles to Pedilanthus tithymaloides (Euphorbiaceae) but also look different.
Please suggest the correct ID.
Looks Pedilanthus tithymaloides only.
Thank you ... for this ID. For me identification of ornamentals is tricky as they show a lot of variations intentionally selected in horticulture/ agriculture. Taking it as P.tithymaloides (Euphorbiaceae).
