Siegfried Reissek (11 April 1819 in Teschen – 9 November 1871 in Vienna) was an Austrian naturalist and botanist who specialized in spermatophytes. He is known for his studies involving plant anatomy and histology.[1]
From 1837 to 1841 he was a student at the University of Vienna. He worked as assistant curator at the Royal Botanical Collection in Vienna between 1845 and 1867, when he was appointed head curator; and from 1848 was a member of the Vienna Academy of Sciences.[2] He circumscribed numerous plant taxa, including the genus Stenanthemum (family Rhamnaceae).[3] The plant genus Reissekia from Brazil (in the family Rhamnaceae) commemorates his name.[4][5]
