Coco-grass

Coco grass (Cyperus rubicundus) is a perennial sedge in the family Cyperaceae, native to tropical and subtropical regions of Africa, South Asia, and Southeast Asia, but now naturalised as a weed across much of the pantropical zone, including the Americas, Australia, and the Pacific. The species forms dense tufts of grass-like foliage growing to 20–60 centimetres from creeping rhizomes and small, dark tubers in the soil. Flower heads are reddish-brown to purplish, borne on triangular stems in compact compound umbels. Like the closely related purple nutsedge (Cyperus rotundus) — one of the world's most problematic agricultural weeds — C. rubicundus spreads aggressively through both seed and vegetative means via its tuber-bearing rhizomes, enabling rapid colonisation of disturbed ground, irrigated fields, gardens, and roadsides in warm climates. The tubers serve as propagules that survive soil disturbance and are difficult to eradicate mechanically, making infestations persistent. Despite its weed status, the species has documented traditional uses: the dried rhizomes have been used medicinally in parts of Asia for gastrointestinal conditions and as an aromatic ingredient in perfumery and cosmetics. Cyperus rubicundus is classified as Least Concern by the IUCN, reflecting its wide distribution and robust, expanding populations in anthropogenic habitats globally. Research into biological control has targeted related invasive Cyperus species in some regions.

Collared Titi

The Collared Titi, known scientifically as <em>Cheracebus torquatus</em>, is a small New World monkey belonging to the family Pitheciidae. <em>Cheracebus torquatus</em> is characterised by its typically dense, soft fur and a pale or white collar or band around the neck and throat region, which gives the species its common and scientific names. Titi monkeys are generally arboreal and highly social, typically living in small family groups occupying territories in forested habitats. They are known for their distinctive pair-bonding behaviour and loud territorial vocalisations. The species inhabits diverse terrestrial and aquatic ecosystems. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Titi is currently assessed as Least Concern on the IUCN Red List.
