Input: Consider Input: Question: How long had Johnson been working at the Gardens? Passage:Persoonia terminalis was first reported by Lawrie Johnson of the Royal Botanic Gardens, Sydney, in the 1981 edition of Flora of New South Wales. He viewed it as a distinctive subspecies of Persoonia nutans, a broadly defined species that included many forms since classified as distinct. Queensland botanists Trevor Donald Stanley and Estelle M. Ross classed P.terminalis as part of Persoonia oxycoccoides in their 1983 work Flora of South-eastern Queensland. They considered it more likely a species in its own right, as they believed the description of the Queensland populations did not match the P. oxycoccoides from central New South Wales. Upon re-examining Persoonia nutans and Persoonia oxycoccoides, Johnson and Peter Weston concluded that there were in fact several distinct species, and that Persoonia terminalis was described as such in 1991. The type specimen was collected south of the Torrington pub on the Emmaville–Torrington road by Weston and ecologist Peter Richards, and is now housed in the National Herbarium of New South Wales, which is part of the Royal Botanic Gardens and Domain Trust Sydney and Office of Environment and Heritage. The Herbarium houses over 1.2million other specimens. The generic name Persoonia is derived from the name of South African botanist Christiaan Hendrik Persoon. The specific name terminalis refers to the inflorescences (clusters of flowers) that are in this species at the ends of the branchlets. Its common name is the Torrington geebung.


Output: Persoonia terminalis was first reported by Lawrie Johnson of the Royal Botanic Gardens, Sydney, in the 1981 edition of Flora of New South Wales


Input: Consider Input: Question: What were the main groups involved in the event that resulted in the sacking of Constantinople in 1204? Passage:Papal calls for renewed holy war at the end of the twelfth century inspired not only the disastrous Fourth Crusade that sacked Constantinople in 1204, but also a series of simultaneous "Northern Crusades" that are less fully covered in English-language popular history, but which were more successful in the long run. Before the crusades, the region of Livonia was a mixed outpost, a pagan society where merchants from the Hanseatic League encountered merchants of Novgorod, and where Germanic, Scandinavian, and Russian trade, culture, and cults all mingled. The specific ethnic groups that intermingled and traded with the Germans, Danish, Swedish, and Russians here included the Wends, who were merchants from Lübeck, the Estonians, the Karelians, the Kuronians, the Lettgallians, the Semgallians (sometimes known as the Letts), the Livonians and the Lithuanians. The Western merchants would trade silver, textiles, and other luxury goods for furs, beeswax, honey, leather, dried fish, and amber. Livonia had been an especially promising location in terms of resources, and Arnold of Lübeck, in his Chronicle of the Slavs wrote that the land was "abundant in many riches" and was "fertile in fields, plentiful in pastures, irrigated by rivers", and "also sufficiently rich in fish and forested with trees".

Input: Consider Input: Question: How old was Boleslaus II of Bohemia when he had to withdraw from Albrechtsburg after Eckard's forced prevailed? Passage:In 985 Otto III appointed him to succeed Margrave Rikdag in Meissen, following severe Saxon setbacks against the Slavic Lutici tribes during the Great Slav Rising. Eckard remained a vital support for the king and his mother Empress Theophanu. His military responsibilities consisted primarily of securing the Milceni lands as well as the containment of the neighbouring Polish and Bohemia duchies. Duke Boleslaus II of Bohemia had allied with Duke Henry and had taken the occasion to occupy the Albrechtsburg residence, he nevertheless had to withdraw by 987, after Eckard's forces had prevailed. According to the chronicles of Thietmar of Merseburg, he was later elected Duke of Thuringia by the magnates of the region, an event which has been taken as evidence of the principle of tribal ducal election. 



Output: Duke Boleslaus II of Bohemia had allied with Duke Henry and had taken the occasion to occupy the Albrechtsburg residence, he nevertheless had to withdraw by 987, after Eckard's forces had prevailed
