T. Cooke [Fl. Pres. Bomb. 3: 278. 1958 (Reprint ed.)], M. M. Bhandari (Fl. Ind. Desert 318. 1978) and Deb & S. Dasgupta (J. Bomb. Nat. Hist. Soc. 75(1): 53. 1978) have adopted Dipcadi erythraeum Webb & Berth., treating Dipcadi unicolor (Stocks) Baker as a synonym. Khatoon & Ali (Chrom. Atlas Ang. Pak. 162. 1993) have used Dipcadi erythraeum Webb & Berth. for Karachi plants having n=11 whereas Turbat and Hoshab population reported to have n=4 is identified as Dipcadi unicolor. Having re-examined the photograph of the Karachi material (n = 11) Khatoon, S. & Ali, (In Ali & Ghaffar, A., Plant Life of South Asia, Karachi, fig. 6, 1991) now agree that the counts for Karachi are better interpreted as 8+3B and 16+6B. As I have only a few specimens at my disposal, presently I have placed both the populations under Dipcadi erythraeum, till more material is available.
Bulbs are eaten in Sindh and Baluchistan.
