The enigmatic name Urginea ecklonii BAKER 1893 has, to date, not yet been applied correctly to either a single plant in the field or to any herbarium specimen as addition to the type and is treated by GOLDBLATT & MANNING (2000: 99) as the only species excluded from Drimia sensu superlatissimo “No authentic material found and probably con‐specific with one of the above”. Both statements in this sentence, however, are inappropriate: 1° there is in Kirstenbosch an isotype of ECKLON & ZEYHER [ Asphod. ] 128 ( d̊ B holo destroyed in 1943, NBG‐SAM lecto; hie designatus, photocopy BTU and PRE) comprising two inflorescences. It is probably filed, however, under Bulbine abyssinica A.RICH., because the inflorescences are mounted on a sheet of Bulbine asphodeloides (L.) WILLD. ( ECKLON & ZEYHER 1692): 2° observations in the field, in the greenhouse and in herbaria indicate that Urginea ecklonii BAKER is not conspecific with one of the species recognized by GOLDBLATT & MANNING (2000), but it is a species of its own, viz. a vegetatively very distinct fynbos species within the Urginea marginata complex. It differs by 2–4 (‐6) ascending lorate leaves from typical Karoo U. marginata with 1(‐2) oblongspathulate leaves appressed to the ground. A distribution map based on 10 collections in addition to the type is presented and shows that Urginea ecklonii is an endemic to the NW subregion ol the Cape Region between Gydopas and Pakhuispas. According to SPETA (1998) the genus Fusifilum RAF. 1837 comprises currently seven species. All seven are his new combinations of old basionyms. Four new combinations were founded on the resurrection of the corresponding genus Physodia in MULLER‐DOBLIES (1996), the three others are obviously misplaced additions without any reasoning. In the present paper a new species. Fusifilum emdeorum J. TANG & WEIGLIN sp. nova, is described and illustrated. Its rather wide distribution in the fynbos of the subregions NW and SW of the Cape Region is given in a map. In addition to four species transferred by U.M‐D., J. TANG & D.M‐D. in MULLER‐DOBLIES (1996) from the present Drimia JACQ. emend. JESSOP (1977) (basionyms Anthericum, Ornithogalum and Urginea ) to Physodia SALISB. 1866, and subsequently transferred by SPETA (1998) to Fusifilum RAF. 1837; emdeorum J.TANG & WEIGLIN sp. nova is described in the present paper.
