Gen info
- Isachne is a  widespread genus of tropical and subtropical plants in the grass family, Poaceae., found in Asia, Africa, Australia, the Americas, and various oceanic islands. They are generally known as bloodgrasses. (4)
- Of the nearly 100 species within Isachne, the majority are amphibious. Some species are regularly found in inundated to permanently wet habitats.
- A serious weed in rice fields.
- Etymology: The genus name Isachne derives from Greek words isos "equal" and achne "chaff", referring to the equal florets, glumes, or lemmas. The specific epithet globosa derives from Latin globosus "globe-shaped", meaning "forming a true sphere." (8)

Botany
• Annuals or short-lived perennial. Culms slender to moderately robust, erect or decumbent and rooting at lower nodes, up to 80 cm tall, nodes glabrous, eglandular or with glandular ring. sheaths shorter than internodes, glabrous except for ciliate outer margin; blades narrowly lanceolate, glabrous, scabrid, base rounded, apex acute; ligule 1-2 mm. Panicle open, ovate in outline, 4-11 cm, glandular, many-spiculate; Spikelets elliptic-globose, 1.5-2(-2.2) mm, greenish or purplish brown; lower floret male, upper floret female; glumes subequal, as long as or shorter than florets, apex broadly rounded; lower lemma oblong, cartilaginous to subcrustaceous, shallowly convex, back sometimes sulcate, smooth, glabrous.

• Perennial. Culms slender to moderately robust, erect or decumbent and rooting at lower nodes, up to 80 cm tall, nodes glabrous, eglandular or with glandular ring. Leaf sheaths shorter than internodes, glabrous except for ciliate outer margin; leaf blades narrowly lanceolate, 3–10 × 0.4–0.8 cm, glabrous, scabrid, base rounded, apex acute; ligule 1–2 mm. Panicle open, ovate in outline, 4–11 cm, glandular, many-spiculate; branches and pedicels filiform, flexuose; pedicels variable in length, shorter or longer than spikelets. Spikelets elliptic-globose, 1.5–2(–2.2) mm, greenish or purplish brown; florets slightly to clearly dissimilar; lower floret male, upper floret female; glumes subequal, as long as or shorter than florets, broadly elliptic, 5–7(–9)-veined, usually glabrous, rarely hispidulous or scaberulous above middle, apex broadly rounded; lower lemma oblong, cartilaginous to subcrustaceous, shallowly convex, back sometimes sulcate, smooth, glabrous; anthers 0.8–1.3 mm; upper lemma crustaceous, shorter and more convex, slightly rough, back glabrous or puberulous, upper margins ciliate.

Uses
Edibility
- No reports found on edibility for human consumption.
Folkloric
- No reported folkloric medicinal use in the Philippines.
- In Sri Lanka, leaves of Isachne globosa and scraped coconut are pounded together, a little water is added, and juice extracted and heated in an earthen pot until it turns to a thick cream. The concoction is applied to reduce swelling after an injury. (6)
- In Bangladesh, leaves paste applied on wounds to stop bleeding. (7)
- In Sri Lanka, used for treatment of fractures.
- Used for treatment of snakebites.
- In south India, whole plant used for treatment of sinusitis.
Others
- Forage: Used as forage for cattle and domesticated animals.

Studies
• Phytoremediation of Mercury (Hg),: Conventional methods for heavy metal removal are often expensive and harmful to the environment. Study evaluated the phytoremediation potential of Isachne globosa for removing and bioaccumulating mercury (Hg) from contaminated environments. Results showed I. globosa plants could accumulate mercury, with highest concentration observed on the 14th day at 25 ppm, reaching a level of 45.860 ppm. Results suggest significant phytoremediation potential for mercury-contaminated environments. (5)

Availability
