Hippomane mancinella (Cultivated)

Hippomane mancinella L., Sp. Pl. 1191 1753. (syn: Hippomane dioica Rottb.; Mancinella venenata Tussac); 
 

The manchineel tree, Hippomane mancinella, is a species of flowering plant in the spurge family (Euphorbiaceae), and the only species in the monotypic genus Hippomane.  

Manchineel is native to Florida in the United States, the Bahamas, the Caribbean, Central America, and northern South America.[1]  
The name “manchineel” (sometimes written “manchioneel”) as well as the specific epithet mancinella is from Spanish manzanilla (“little apple”), from the superficial resemblance of its fruit and leaves to those of an apple tree. A present-day Spanish name is in fact manzanilla de la muerte, “little apple of death”. This refers to the fact that manchineel is one of the most poisonous trees in the world. 
Manchineel is a tree reaching up to 15 meters high with a greyish bark, shiny green leaves and spikes of small greenish flowers. Its fruits, which are similar in appearance to an apple, are green or greenish-yellow when ripe.The manchineel tree can be found near to (and on) coastal beaches.
It provides excellent natural windbreaks and its roots stabilize the sand, thus helping to prevent beach erosion.

Please help to identify this tree from Baroda. I hope identification is possible in the absence of flowers and fruits. The leaves exude a thin milky sap and the leaf margin is toothed. I also noticed a gland on the leaf stalk.

This is Hippomane mancinella of Euphorbiaceae, one of the most poisonous trees on the planet

in this link, some one identified it near Baroda in 2013. i have done it in 2007 that was published in my book ‘trees of Gujarat’ published by forest dept.

but other than baroda, which other states/ places/?

No idea, …

thank you very much. i have my email correspondences about Hippomane (in 2007). There are trees (2) one in Sayaji baug in Baroda and other near boys’ hostel in The MS Univ. of Baroda’s campus. There were two more young trees growing in Kirimandir nursery (then governed by Forest Dept) near my residential area. it was grown due to its mis-identification as some Ficus sp., that i asked to remove and forester did that.

One more tree i found in Junagadh Agricultural University.

Fwd: Sapium insgne : 4 posts by 2 authors

I read the description about Sapium insigne or Falconeria insigne. I would like to know if the two pairs of glands present at the base of lamina can be presented in the form of a single gland? You mentioned 7 by 4.5-6 mm of the fruit size, now I would like to know, if this size can be bigger? As there are few trees in different Gardens in my state, with similar characters, but leaves with one or two glands at the juncton of petiole and blade (lamina) as well as fruits are 1 by 1.5-2.5 cm (not mm). And these plants are marked as Sapium insgne var. malabarcum. I will be happy if you share your knowledge. I know that you have describe species and not the variety of above said plant, but Botanical Survey of India in their Flora of Maharashtra (Flora of India Series) describes fruits with same small sizes as mentioned by you.

Hope to hear you soon.

In all specimens of Falconeria I studied for my revision some years ago, I had only few plants from India. All had nearly the same fruit size. I studied not only Falconeria but also several related genera. As a result of my research I know that fruit size is not very variable in any of the species. The variation is few millimeters only. If you have plants with fruits 1.5 or 2 cm large, they cannot be the same species, not even as variety.

The number of size of the petiolar glands is very constant within a genus, in all genera I studied. Falconeria will always have two glands on the petiole. If the glands in your plant are united to form a single gland, I suspect that it cannot be Falconeria.
If you can send an image, I can perhaps tell you more.

Thank you for your response.

I have clicked pictures of this plant and as here it is midnight, the close ups are not very well lighted, yet enough to check details.
These trees are about 10 m tall, Habit photo may help you look the bark which is grey, with superficial, vertical fissures.
Leaves are on the branch tips, wth serrated margin and long petiole (almost as long as or even longer than lamina). the close ups have leaves those are smaller in size otherwise, on trees, there are leaves bigger than those seen in picture.
Fruits are fleshy, green with milky latex, slowly they turn dry, Each locule wth one or two seed. Seeds covered with thin, brown, papery skin covering nner, off-white grain.
Hope this will be of some use to you, yet, if needed can send some more pictures in few days.

The above pics are not of Sapium, but Hippomane, pl. note.

I was not knowing about this cultivated species. Dr. Hans-Joachim Esser made drastic overhauling of the Hippomaneae and we all are following his treatment. He is the best person to comment on this plant.
