General/Distribution: A small family of 3 genera and about 10 species, mostly of African desert (Saharo-Sindian region). Represented by only I genus in Pakistan.
Comment/Acknowledgements: The genera now comprising Neuradaceae, were previously placed in a separate tribe of Rosaceae by de Candolle (Prodr. 2: 548.1825), Bentham & Hooker, f. (Gen. Pl. 1: 605.1865) and Hooker f. (Fl. Brit. Ind. 2: 308.1878) or in a subfamily by Endlicher (Gen. Pl. 1249.1840). However, it was recognized as an independent family by J.G. Agardh (Th. Syst. Pl. 288. 1858) which was followed by Airy-Shaw, (Diet. Fl. Pl. Ferns, 1973), Takhtajan, (Fl. Pl.: Origin and Disp.223. 1969) and Cronquist, Evol. Class. Fl. Pl.368. 1980). The family Neuradaceae differs from Rosaceae (s. str.) by its connate carpels within the calyx tube, and very unique type of pollen grains which have 3-armed aperture at both the poles and each arm is provided with a circular ores. Hence it is justified to treat Neuradaceae as an independent family.
