Wild material	Plants very much past ripeness (exceptionally dry year in this region), the husks tattered from bird predation, but some seeds still in husks, especially where leafsheaths and husk have been entwined by an ubiquitous purple Ipomea. Seeds gathered by shaking seeds out over a plastic sheet, over 1 kg gathered by two people in about 2 hours. Plants very variable in appearance: a) Completely free of long slender lateral branches (i.e., unbranched) and very slender themselves, to 2.5 meters tall if growing in densest thickets with much shade and intense competition from tall herbs (Tithonia, etc.). b) Robust and branched above, with 3-7 lateral branches, if initially shaded in their lower portions (during early growth) and in competition with shorter plants. c) Branched, with 7 to 9 branches from very base if growing in among the maize plants and free of shading, here to only 1.2 meters tall (i.e. branching quite dependent on whether plants open grown or shade grown). Plants all strictly annual, without any rhizomes. No F1 seen or any evidence of hybridization.	1336869	PI 441933
