      Species name: Acicarpha spathulata R. Br
    Acicarpha spathulata represents the Calyceraceae, which is the sister family of the Compositae. Evolutionary genomic analyses of Acicarpha are useful for elucidating genetic and genomic changes associated with the origin and early diversification of the Compositae. Acicarpha spathulata is an herbaceous perennial native to coastal Brazil. It has a gametophytic chromosome number of 8, but its genome size is unknown.

    We generated the EST library described above, which is being used to determine the distribution of whole genome duplications in the Compositae and closely related families.
