Christian Luerssen (1843-1916) was a professor at Königliches botanisches Institut in Königsberg (now Kaliningrad). In 1917 part of his botanical collection was donated by Otto Bjurling to the Swedish Museum of Natural History. The collection includes European pteridophytes mostly from East and West Prussia collected between 1880 and 1910. The material has been cited i "Luerssen, C., 1894, Beiträge zur Kenntnis der Flora West-und Ostpreussens. I-III. - Bibliotheca Botanica. 6 (28): 1-58, pl. I-XXIII (Stuttgart)."
