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.

Key Differences Between Species

• Stems and Hair: Euphorbia hyssopifolia often has hairy (pilose) stems, particularly when young, though they can be smooth. Euphorbia hypericifolia is typically entirely hairless (glabrous).
• Flowers (Cyathia): E. hyssopifolia has denser, tighter flower clusters that are often located at the end of branches. E. hypericifolia has flowers in smaller, looser clusters on arching branches.
• Stipules: E. hyssopifolia has stipules less than 1mm long and erect. E. hypericifolia has stipules longer than 1mm that spread away from the stem.
• Habit: E. hyssopifolia tends to be more erect, while E. hypericifolia is known for its arching, reddish stems.

Detailed Comparison

• 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: 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.

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.

Dear Garg ji, Saroj ji,

Thank you very much for sharing the details and links for identification of my plant.

My plant is hairless, but not a garden plant and the flowers seems to be more sized in efi images than that of my plant.

With kind regards,

Sam Kuzhalanattu.
