Glinus lotoides is native to Eurasia and Africa and has become widespread in tropical, subtropical, and warm-temperate areas worldwide. Several varieties have been described, but their delimitations are unclear and need further investigation. The vernacular name 'damascisa' is applied to this species, as well as several other plants, which are used in Africa for treatment of diabetes and skin ailments (A. El-Hamidi et al. 1967). In India, the species is used as treatment for diarrhea, boils, and abdominal diseases, as well as weakness in children (K. R. Kirtikar and B. D. Basu 1935). Antihelmintic properties are reported for G. lotoides from several African studies (B. Abegaz and B. Tecle 1980; G. Broberg 1980).
STEMS: to 25 cm long. LEAVES: to 26 mm long, to 14 mm wide. FLOWERS: mostly 4-10 per cluster, the pedicels to 2 mm long; sepals 5-7 mm long, the apex acute to slightly mucronate. SEEDS: ca. 0.4-0.6 mm long, red-brown to dark brown, tuberculate. 2N = 36. NOTES: Margins of stock ponds: Pima co.; 350 m (1090 ft); mostly summer-fall, potentially year-round; s. U. S., Mex., native to Eur. Known in AZ from three collections (Felger 92-565, 92-714 & 93-94, ARIZ), all from the Jose Juan Tank (stock pond) in Cabeza Prieta National Wildlife Refuge.
