Abstract
1. Five species of Abelmoschus-A. esculentus (Linn.) Moench. (the cultivated species), A. ficulneus (L.) W. & A., A. manihot (L.) Medik., A. manihot (L.) Medik. var. pungens (Roxb.) Hochr., and A. tuberculatus-have been studied morphologically and in interspecific hybridization. These studies have confirmed the view that these species constitute a distinct taxonomic unit. 2. Results show that A. tuberculatus sp. nov. is more nearly related to A. esculentus than any other species, and A. manihot follows it. A. manihot var. pungens rightly appears to be a variety of A. manihot as adopted by Hochreutiner. A. ficulneus is, however, only distantly related. Whereas the other four species readily crossed with each other and formed normal viable seeds, crosses with A. ficulneus resulted in only shriveled or empty seeds. 3. The various F1 hybrids studied were sterile; fruits were formed which were, however, either seedless or developed only a few empty seeds. 4. Backcrosses and crossing of the hybrids in various combinations failed to produce viable seeds. 5. Some useful characters of the wild species have been indicated. 6. A new species, A. tuberculatus Pal et Singh, is described.
