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.

Yellow-collared Lovebird

A small lovebird with distinctive yellow collar and mask surrounding a violet-blue face, native to the dry Acacia savanna of northeastern Tanzania. Like all lovebirds, they form intensely bonded pair relationships reinforced through constant mutual preening. They nest colonially in large tree holes and termite mounds, lining nests with strips of bark. Near Threatened due to trapping for the pet trade and agricultural habitat conversion. Widely hybridized with Fischer's lovebird in captivity.
