CYPRIPEDIUM CRUCIFORME, HEINRICH ZOLLINGER, WILHELM HENDRIK DE VRIESE, AND ALEXANDER MORITZI

摘要

THERE ARE MANY beautiful illustrations of Paphiopedilum species in old books or old journals, some of them are well known, some others almost forgotten. Cypripedium cruciforme is a good example in the category of the almost forgotten illustrations. Its history and the history of the involved botanists are interesting enough to be published.
