Notes

Detailed descriptions and drawings of caryopses are presented for 35 species representing 18 genera in the Triticeae. We studied the morphological variation in non-embryo characters involving the length, shape, compression, lateral ridges, sulcus development, coronas, and apical hairs of the caryopsis. Based on shared characters of the caryopses, we recognize three groups of genera as two major subtribes and one monogeneric subtribe. The Hordeinae includes Agropyron, Crithopsis, Elymus, Elytrigia, Eremopyrum, Hordelymus, Hordeum, Leymus, Psathyrostachys, and Taeniatherum; Triticinae includes Aegilops, Amblyopyrum, Dasypyrum, Heteranthelium, Secale, and Triticum; and Henrardiinae includes Henrardia. Similarities among the caryopses of 14 species of Elymus, Elytrigia, Leymus, and Psathyrostachys support a broad interpretation of Elymus. The caryopses of Brachypodium resemble those of the genera in the Hordeinae and to some extent Bromus.
