Horstrissea dolinicola, a New Genus and Species of Umbels (Umbelliferae, Apiaceae) from Kriti (Greece)
Το Horstrissea dolinicola είναι ενδημικό της Ελλάδας καθώς φύεται μόνο στον Ψηλορείτη (Ίδη) στην κεντρική Κρήτη σε περίπου 1.500 μ. υψόμετρο, και πουθενά αλλού στον πλανήτη. Επιπλέον, το γένος Horstrissea είναι ένα από τα ελάχιστα (5-6) ενδημικά γένη της Ελλάδας. Εξαιτίας της περιορισμένης εξάπλωσης και των απειλών που δέχεται το είδος, έχει χαρακτηρισθεί ως CR (Κρισίμως Κινδυνεύον) σύμφωνα με τα κριτήρια της Διεθνούς Ένωσης για την Προστασία της Φύσης (IUCN) και περιλαμβάνεται στο Βιβλίο Ερυθρών Δεδομένων των Σπάνιων και Απειλούμενων Φυτών της Ελλάδας. Συμπεριλαμβάνεται στα 50 Κορυφαία Φυτά των Νησιών της Μεσογείου σύμφωνα με ομάδα ειδικών.
A new species of umbels, belonging to an undescribed new genus, was discovered in two neighboring lines of the Psiloritis mountain range in central Kriti, at an altitude of c. 1500 m. It is a highly specialized plant, whose most unusual feature is leaf development: the ultimate portions of the tritemate basal leaves emerge individually on the surface of the sandy ground, being borne on long, flexuous subterranean petioles and petiolules. The new species is fully described and illustrated, and its ecology is outlined. The relationships of the new genus are discussed. It belongs to the Apieae (=Ammieae) but is probably closest to Scaligeria, a genus hitherto misplaced in the Smyrnieae, which it resembles in its geophytic habit and fruit structure. The chromosome number 2n = 14 was counted for Horstrissea. The basis x = 7 is unusual in the Umbelliferae and has so far been reported only once in a potentially allied genus, Bunium, where it is considered as derived through descending aneuploidy from the primitive x = 11.
The precursor of Willdenowia was founded in 1895 as Notizblatt des Königlichen Botanischen Gartens und Museums zu Berlin to publish information about the institution’s collections and activities, and research contributions from its staff and associated botanists. Revived in 1953, after the fatal destruction of much of the institution’s collections and facilities in World War II, initially as Mitteilungen aus dem botanischen Garten und Museum Berlin-Dahlem, then with its present title commemorating Carl Ludwig Willdenow (1765-1812, director of the garden and first professor of botany in Berlin), it has grown to a peer-reviewed journal with international authorship publishing original research papers in English on plant taxonomy, plant systematics, floristics and plant geography. JSTOR provides a digital archive of the print edition of Willdenowia and its precursors. The electronic edition (1996 – present, since 1999 with supplement content not found in the print edition) is available at http://www.bgbm.org/willdenowia/ for authorized users. Publisher Information
Botanic Garden and Botanical Museum Berlin-Dahlem (BGBM) forms a central facility of Freie Universität Berlin. The institution’s goal is to maintain and enlarge botanical collections both living and preserved, to promote research, and to act as a center for education and information in botany. BGBM comprises (1) one of the largest and most diverse botanical gardens in the world, (2) an extremely rich herbarium, (3) a magnificent library, and (4) one of the most extremely-view botanical museums in existence. Founded in 1679 by the Great Elector and becoming part of Berlin University upon its foundation in 1810, the institution was moved to much larger premises in Dahlem becoming operational on the new site in 1910. After substantial destruction in 1943-5, both the garden and museum were restored and form today one of the largest institutions of its kind in Europe.
