31 T\«o genera and one species ofUmbelliferae new to the flora ofJordan by D. AL-EISAWI, S. ORAN& D. PODLECH Abstract: Al-Eisawi, D., Oran, S. & PODLECH, D.: Twogenera andone species ofUmbelliferae newto thefloraofJordan. -Sendtnera2: 31-34. 1994. ISSN0944-0178. Two genera of Umbelliferae are recorded as new to the flora of Jordan. These genera are Hohenackeria and Oliveria. The two genera are represented by the species Hohenackeha exscapa (Steve.) Kos.-Pol. and Oliveria decumbens Vent. A third species of Umbelliferae Ducrosia anethifolia (DC.) Boiss. is also recorded new to the flora ofJordan. Hohenackeria exscapa was collected fi^om the mountains ofShaubak in Southern Jordan, while the other two species were collected fi^om the Eastern Desert ofJordan. The distribution will be shown in a map. Since the publication ofthe List ofJordan Vascular Plants (Al-EISAWI 1982) some more new species have been recorded parallel to the increase of collections especially when new localities arevisited in different seasons (Al-Eisawi 1986 a& b). Althoughtherewas aPh. D. theses ontheUmbelUiferae ofJordan(AL-ElSAWi 1977)thesenew specieswereup to thistime not discovered inJordan. Specimens ofthe newly recorded taxa are deposited at the Herbarium, Department ofBio- logical Sciences, FacultyofScience, University ofJordan, Amman, Jordan (AMM). Duplicates ofthese taxa are also deposited at theHerbarium, Institut für Systematische Botanik, Munich, Germany. Hohenackeriaexscapa(Stev.)Kos.-Pol. This genus is know from Transcaucasia, Persia, Anatolia, North Africa and Spain, (Hedge & Lamond 1974, 1987). It is clear from the distribution ofthis species that there is a gap between its distribution in Asiato North Africa and South Western Europe. Its new collection in Jordan represents the closest bridge ofthis link. Thegenus and its only species has not been recorded in the floras covering or Jordan or neighbouring countries such as BOISSEER (1872), Post(1932), ZOHARY (1972), MOUTERDE(1970) orTACKHOLM(1974). This genus was found in the high mountains ofAsh-Sharah, Southern Jordan at an altitude ofabout 1300-1400 m. inadegradedforestland cultivatedbywheat. Materialseen: Jordan: Shaubak; Ail, 3 kmW. ofAil, along the road to Rajifcultivated field. 14 May 1992, Al- Eisawi 17172-B. 32 OliveriadecumbensVent. Syn.: O. orientalisDC, O. bruguieriJaub. & Spach, CallistromaerubescensFenzl Distribution: Turkey, Syria, Iraq and Iran. The specimens ofthis genus were collected from the Eastern Desert ofJordan from three different localities. One of them was collected few years ago, 1987, while the other two localities were gathered in 1993. The genus was not recorded previously in the area by Post (1932), MOUTERDE (1970), ZOHARY (1972), Hedge & Lamond (1974) and TÄCKHOLM (1974). Material seen: Jordan: Eastern Desert: nearby the main road to Azraq; between Muwagar & Qasr Amara, Hammada land covered by graels with clayey, loess soil, 7 June 1987, Al-Eisawi 13447; 20 km E of Safawi, 10 km N ofthe main road at the hot well point, towards Shbaika track. 28 April 1993, Al- Eisawi 18191; Eastern Desert: 20 km E ofSafawi, along the Ruwayshid, 23 April 1992, Al-Eisawi 16033.

ThegenusDucrosiawasrecordedforthefirsttimetothefloraofJordanbyBOULOS& Al- ElSAWi (1977) asrepesentedbythe speciesDucrosiaflabellifolia. Recentlythe second species D. anethifolia was found from the North Eastern Desert ofJordan close to the borders with Iraq. Both specieswerenotrecordedbyZOHARY(1972) orPost(1932) asto occurin Jordan. Rechinger (1964) has recorded these two species from Iraq, in Rutba close to the borders withJordan. Alava (1975) in his papaer "The Genus Ducrosia and its Allies" givesthe distri- bution ofthis species as Syria, Arabia, Iraq, Iran, Afghanistan, Pakistan. He did not list Jordan orPalestine aslocalitiesofdistributionforthis species.
