An Unusual Xylotheque with Plant Illustrations from Early Meiji Japan. Two unusual wood collections, reported previously in the collections of the Botanical Museum at Berlin-Dahlem and the Royal Botanic Gardens, Kew, take the form of framed plant illustrations painted on boards made from the wood of the species illustrated. We present new finds of very similar wood collections in the Economic Botany Collection of the Harvard University Herbaria, a private collection in the U.K. (Loudon collection), and at the Koishikawa Botanical Garden of the University of Tokyo. A stamp on the reverse of the boards links all five collections to Chikusai Kato, an artist working at Tokyo University (now the University of Tokyo) in early Meiji Japan, under the direction of the preeminent nineteenth century Japanese botanist Keisuke Ito. New evidence from contemporary historical accounts indicates that more than 100 boards were ordered in June 1878 by Hiroyuki Katō, the first president of Tokyo University, most likely to support the early teaching of Western-influenced botanical science in Japan. However, while the boards had clear value for teaching, especially about useful plants, their unusual fusion of Western and Japanese influences also made them desirable craft objects that were collected and given as gifts during the early Meiji era.明治初期に日本で作られた特異な植物図版について これまでベルリン・ダーレムの植物博物館とイギリス王立キュー植物園に知られていた植物図版は、枠付きの木製の板の上に描かれており、その板はその植物の材を用いられていることで大変特徴的である。最近、同様な植物図版がハーバート大学植物標本館、ロンドン個人コレクション(Loudon氏蔵)と東京大学附属小石川植物園にも見出された。裏面の篆刻印から、これらの植物図版は東京大学創立初期の1878年に当時の著名な植物学者伊藤圭介教授の指導の下に、そこで働いていた植物画家加藤竹斎によって描かれ、制作されたことが分かる。当時の資料などから新たに分かったことは、当初作成された100枚余の植物図版は初代東京大学総長(当時は総理といった)によって、近代的植物科学の教育手段として購入されたと推定される。しかしながら、これら図版は有用植物の教育手段として優れているが、同時に西洋と日本の画法の融合したユニークな図版であることから工芸品としてもみなされ、明治初期には収集されたり、また、贈答品としても用いられていたことが分かった。

Understanding transcontinental biogeographic patterns has been one of the main foci of the field of biogeography. While multiple explanations for transcontinental disjunctions have been proposed, little is still known about the relative importance of intrinsic and extrinsic traits for the diversification dynamics of disjunct taxa. Here, we study the evolutionary history of the genus Picris L. (Compositae), a great model for investigating the diversification dynamics of transoceanic bipolar disjunct organisms. Ancestral state reconstructions indicate that the most recent common ancestor (MRCA) of Picris was a semelparous and heterocarpic herb that lived in unpredictable environments of North Africa and West Asia. Diversification analyses suggest a significant shift in speciation ca. 1 million years ago, likely associated with the onset of the mid-Pleistocene revolution. Longevity characters are correlated with the evolution of particular fruit types and with environmental conditions. Heterocarpic species are mostly semelparous herbs strongly linked with unpredictable habitats, while homocarpic taxa are mostly iteroparous plants occurring in predictable environments. Binary-state speciation and extinction analyses suggest that homocarpy, iteroparity, and habitats predictability accelerate diversification. Although the combination of homocarpy and iteroparity evolved in several lineages, only members of the P. hieracioides group were able to colonise Eurasia and expand to Australia by transoceanic dispersal. Those findings indicate that large-scale colonisation events depend on a complex interplay of intrinsic and extrinsic factors.

Abstract: The herbarium of Ignaz Dörfler (1866–1950), an Austrian botanist, plant collector and trader, was acquired by the Botanical Museum Berlin (B) in 1990 and has now been incorporated into the general herbarium. Dörflers herbarium comprises c. 5500 specimens, including 203 types, almost exclusively collected by himself on the Balkan Peninsula and in Central Europe. The type material is listed in detail and 21 names are lectotypified. In addition, a brief biography of Dörfler is presented. Citation: Vogt R., Lack H.

Hildemar Scholz, aged 84, passed away on 5 June 2012 as a consequence of a bad fall he had suffered at home a few weeks earlier. He was a world authority on temperate old world grasses, the adventive flora of Europe and Central European rust fungi. From 1964 until his retirement in 1993 he was a member of staff of the Botanic Garden and Botanical Museum Berlin-Dahlem, rising from scientific collaborator to one of the directors at this institution. Hildemar was a born plant-collector with a special interest in grasses and in the flora of the Berlin area, as well as a member of the Botanischer Verein von Berlin and Brandenburg, for which he acted as its President from 1984 to 1987. Born on 27 May 1928 in Berlin into a family of protestant clergymen, Hildemar Scholz remained both in language and manners very much a Berliner, in the true and best sense of the word, and never ever considered leaving his home town, even during the many difficult years this city encountered in the last century. At an early age he moved with his parents to Buchholz near Treuenbrietzen and subsequently to Pritzwalk, both in the province of Brandenburg, where, initiated by his nature-loving father, he received his first impressions of the flora of this area. Like so many of his generation, among them Helmut Kohl, former German federal chancellor, and Josef Alois Ratzinger, now Pope Benedict XVI, Hildemar, then aged 15, was drafted Flakhelfer (anti-aircraft warfare helper). He was on duty in Stettin [now Szczecin, Poland] and later in Berlin, where in early spring 1945 he had to defend the Moltke Bridge opposite the Reichstag in the city centre against the victorious Soviet army. Having survived the battle of Berlin, Hildemar had the good luck of being sent home at an early date from a prisoner-of-war camp west of the river Oder by a kind-hearted Soviet woman doctor who simply pointed west, telling him: “Mama, Berlin”. Having belatedly finished his school training in 1947, he tried to get enrolled at Berlin University, subsequently renamed Humboldt University, in the Soviet sector of the city, but was rejected, probably because his father was a clergyman. Hildemar had more success at the newly founded Freie Universität in the American sector of Berlin, where he got admitted in 1949 and chose biology as his subject. The next year he met his fellow biology student Ilse Reimers, daughter of the bryologist Hermann Reimers, then Kustos (Curator) at the Botanic Garden and Botanical Museum Berlin-Dahlem. The resulting marriage became a prominent element in Hildemar’s life, in particular since the couple shared so many botanical interests, which at least in part were also those of Ilse’s father. The latter, after all, also had a special interest in rusts, in the floristic exploration of Central Europe and had been President of the Botanischer Verein der Provinz Brandenburg, the precursor of the Botanischer Verein für Berlin und Brandenburg (Scholz & Scholz 1962). Clearly Ilse became in later years Hildemar’s assistant and aid in many of his endeavours as well as second author of sev-
