I am confused between the these two species (I will go for Euphorbia hypericifolia): *Euphorbia hyssopifolia* and *E. hypericifolia* are similar annual, weedy spurges often confused, but they differ primarily in hairiness and inflorescence structure. *E. hyssopifolia* has pilose (hairy) stems and dense clusters, while *E. hypericifolia* is typically glabrous (hairless) with more arching, leafy stems and denser flowers.

[image: Wikipedia]Wikipedia +3 Detailed Comparison - Euphorbia hyssopifolia <https://en.wikipedia.org/wiki/Euphorbia_hyssopifolia>: Often referred to as Hyssop Spurge, this annual herb grows up to 80 cm tall. It has green leaves with oblique bases. The seeds are cross-ridged, which helps distinguish it from similar species. - Euphorbia hypericifolia <https://en.wikipedia.org/wiki/Euphorbia_hypericifolia>: Commonly known as Graceful Spurge, this plant is used in gardening (notably in the 'Diamond Frost' cultivar). It is a hairless annual forming a mound, often used as an ornamental, unlike the purely weed-like nature of similar species. [image: Wikipedia]Wikipedia +4 *Note: Due to their similar appearance, these two species are frequently misidentified in the field, and some regional literature treats them as synonyms or with overlapping characteristics, particularly regarding the hairiness of E. hyssopifolia.* [image: eFlora of India]eFlora of India +1 On Mon, 2 Mar 2026 at 14:07, Saroj Kasaju <[email protected]> wrote: > *Euphorbia hyssopifolia *L. > > Thank you. > > Saroj Kasaju > > > On Mon, Mar 2, 2026 at 2:11 PM Sam Kuzhalanattu <[email protected]> > wrote: > >> Sharing more images >> >> On Mon, 2 Mar, 2026, 1:54 pm Sam Kuzhalanattu, <[email protected]> >> wrote: >> >>> Sharing more images >>> >>> On Mon, 2 Mar, 2026, 1:54 pm Sam Kuzhalanattu, < >>> [email protected]> wrote: >>> >>>> Sharing more images >>>> >>>> On Mon, 2 Mar, 2026, 1:53 pm Sam Kuzhalanattu, < >>>> [email protected]> wrote: >>>> >>>>> Sharing more images >>>>> >>>>> On Mon, 2 Mar, 2026, 1:48 pm Sam Kuzhalanattu, < >>>>> [email protected]> wrote: >>>>> >>>>>> Sharing more images >>>>>> >>>>>> On Mon, 2 Mar, 2026, 1:47 pm Sam Kuzhalanattu, < >>>>>> [email protected]> wrote: >>>>>> >>>>>>> Sharing more images >>>>>>> >>>>>>> On Mon, 2 Mar, 2026, 1:46 pm Sam Kuzhalanattu, < >>>>>>> [email protected]> wrote: >>>>>>> >>>>>>>> Sharing more images >>>>>>>> >>>>>>>> On Mon, 2 Mar, 2026, 1:45 pm Sam Kuzhalanattu, < >>>>>>>> [email protected]> wrote: >>>>>>>> >>>>>>>>> Please ID wild plant Euphorbiaceae, kind regards, Sam Kuzhalanattu. >>>>>>>>> >>>>>>>>> Location: Chavara Kollam Kerala INDIA >>>>>>>>> >>>>>>>>> Altitude: 10fsl >>>>>>>>> >>>>>>>>> Flower date: 30DEC2024, 04.55pm >>>>>>>>> >>>>>>>>> Habitat: wild moisture sloppy grassland >>>>>>>>> >>>>>>>>> Plant habit: small branched lactiferous unisexual herb, weak >>>>>>>>> cylindrical purplish stem 06mm base diameter, perennial >>>>>>>>> >>>>>>>>> Height: 45cm >>>>>>>>> >>>>>>>>> Leaves: opposite ovate obtuse acute leathery serrated margins, >>>>>>>>> size upto: 03x1cm >>>>>>>>> >>>>>>>>> Flower: axillary umbel inflorescence, clustered, green into white >>>>>>>>> to pink, non fragrant >>>>>>>>> >>>>>>>>> Fruit: capsule lobed green into brown ovoid size:04x03mm >>>>>>>>> >>>>>>>>> Seed: >>>>>>>>> >>>>>>>> -- >> You received this message because you are subscribed to the Google Groups >> "eFloraofIndia" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to [email protected]. >> To view this discussion, visit >> https://groups.google.com/d/msgid/indiantreepix/CADkXgDRgNgRhn8y8rp-JqC%2BUNeZqBGfFm%2Bb%2B0Q6vsWs8nrUznw%40mail.gmail.com >> <https://groups.google.com/d/msgid/indiantreepix/CADkXgDRgNgRhn8y8rp-JqC%2BUNeZqBGfFm%2Bb%2B0Q6vsWs8nrUznw%40mail.gmail.com?utm_medium=email&utm_source=footer> >> . >> > -- With regards, J.M.Garg, https://efloraofindia.com/ -- You received this message because you are subscribed to the Google Groups "eFloraofIndia" group.
