Context	Classification to groups
Elongate psilate	Leaf/stem
Elongate irregular	Leaf/stem
Elongate echinate indet.	Unknown inflorescence (not included in analysis)
Echinate wheat/barley type	Wheat/barley inflorescence
Elongate dendritic wheat/barley type	Wheat/barley inflorescence
Elongate echinate short spine	Weedy type inflorescence (wheat/barley, millet and rice)
Elongate echinate hook spine	Weedy type inflorescence (wheat/barley, millet and rice)
Elongate dendritic short spine	Weedy type inflorescence (wheat/barley, millet and rice)
Elongate echinate wavy millet type indet.	Millet inflorescence
Elongate echinate wavy Echinochloa-type	Millet inflorescence
Elongate echinate wavy Brachiaria-type	Millet inflorescence
Elongate echinate wavy Pennisetum-type	Millet inflorescence
Elongate echinate wavy cf. Sorghum-type	Millet inflorescence
Elongate echinate wavy cf. Setaria verticillata-type	Millet inflorescence
Elongate echinate wavy cf. Setaria italica-type	Millet inflorescence
Elongate echinate wavy Panicum miliaceum-type	Millet inflorescence
Elongate non-psilate	Leaf/stem
Double peak husk	Rice inflorescence
Commelinaceae (Eichhorn^a L)	Commelinaceae: weedy (rice)
Commelinaceae (Eichhorn^a K)	Commelinaceae: weedy (rice)
Commelinaceae (Eichhorn^a A)	Commelinaceae: weedy (rice)
Commelinaceae (Eichhorn^a I)	Commelinaceae: weedy (rice)
Commelinaceae indet. cone	Commelinaceae: weedy (rice)

Only those forms included in the analysis have been outlined here. For full dataset see Bates (2016). Grass short cells were not included as these are commonly found in both inflorescence and leaf/stem and therefore cannot be used to refine the crop processing models
