Common wheat [SEP] Other forms of common wheat
Compact wheats (e.g., club wheat "Triticum compactum", but in India "T. sphaerococcum") are closely related to common wheat, but have a much more compact ear. Their shorter rachis segments lead to spikelets packed closer together. Compact wheats are often regarded as subspecies rather than species in their own right (thus "T. aestivum" subsp. "compactum").
