1999BN28740Spektrum Akademischer Verlag 1999. 1999. Softcover. 24 x 17 x 1 cm. The subphylum Clitellata of the phylum Annelida contains several classes of organisms dwelling in freshwater systems. The systematic concepts of these groups are still a matter of discussion at all taxonomic levels involved. It is hoped that the interrelationships of systematic entities within and above the species level will be better understood as additional and more precise data on morphology anatomy and genetics become available. The aim of this volume is to present a compilation of valid tax described from the western Palaearctic area including the fauna of the Egyptian Nile in order to serve as a fundament for future work. This contribution covers three classes of leeches: the Branchiobdellida which live as epizoons on freshwater decapods the small class Acanthobdellea comprising highly specialised parasites living on freshwater fishes and finally the class Hirudinea which contains species commonly known as the "classical" leeches. Standardised descriptions of the morphology of all species are given. Whenever possible these are amended by data on anatomical details to allow correct identifications. Most of the species are illustrated many of them for the first time. The keys cover all taxa known from the geographical range under consideration. They are especially constructed to be used by biologists in the field thus enabling fast access to an unknown species without dissection. Whenever possible information on biology ecology and distribution is supplied although many of these data have to be used very carefully to avoid the hitherto known frequent misinterpretations.

Illustrated with 24 fine engraved plates of which two are folding small thick octavo pp 28 482 30 4-page bookseller's catalogue Blanche Henrey points out that page numbers 281-288 are repeated a printer's error a few very slight marks or paper imperfections but generally a remarkably clean bright and tight copy the front hinge is cracked but without any weakness the front free endpaper however is partially loose and may soon become completely so an armorial bookplate on the front endpaper contemporary panelled calf scuffed age-toned and worn at the corners neatly rebacked with a new calf spine a calligraphic paper title label. Blanche Henrey 323. John Ray FRS 1627 - 1705 was a Christian English naturalist widely regarded as one of the earliest of the English parson-naturalists.His classification of plants in his earlier Historia Plantarum was an important step towards modern taxonomy. Ray rejected the system of dichotomous division by which species were classified according to a pre-conceived either/or type system and instead classified plants according to similarities and differences that emerged from observation. He was among the first to attempt a biological definition for the concept of species as "a group of morphologically similar organisms arising from a common ancestor". Another significant contribution to taxonomy was his division of plants into those with two seedling leaves dicotyledons or only one monocotyledons a division used in taxonomy today. "In the Synopsis apart from the Linnean nomenclature we have a modern hand-book. The survey of species is remarkably accurate at least in flowering plants. The country has been adequately explored. The names and brief descriptions make identification easy. The classification if not scientifically perfect follows a natural sequence and is as easy to use as the modern scheme. British botany has been given a secure and intelligible foundation" - John Raven. Full Leather. Very Good. Gulielmi & Joannis Innys Hardcover

Synopsis Plantarum Glumacearum: Part 1 - Gramineae

1855017571Stuttgart: J.B. Metzler 1855. Large octavo pp viii 474 ii some foxing and age-toning throughout but otherwise very sound internally bound in half cloth and marbled boards probably early twentieth century slightly rubbed. One of the cornerstones of nineteenth century grass taxonomy. The second part concerned Cyperaceae. RARE and one of the best possible provenances - Eduard Hackel's copy with his extensive manuscript notes and insertions throughout. It then passed to the Dutch agrologist Pieter Jansen who gifted it to C.E. Hubbard after a visit to the Kew Herbarium. ERNST GOTTLIEB VON STEUDEL was born at Esslingen am Neckar in Baden-Württemberg. He was educated at the University of Tübingen earning his medical doctorate in 1805. Shortly afterwards he settled into a medical practice in his hometown of Esslingen and in 1826 became the chief state physician in what had become the Kingdom of Württemberg. In 1825 together with Christian Ferdinand Friedrich Hochstetter 1787-1860 he organized an organization in Esslingen known as Unio Itineraria Württembergischer botanische severein. The purpose of this society was to send young botanists out into the world to discover and collect plants in all of their varieties thus promoting and expanding botanical studies and herbaria throughout the Kingdom and beyond. Hochstetter himself traveled to Portugal Madeira and the Azores and Steudel was able to create a herbarium of over 20000 species. EDUARD HACKEL 1850 - 1926 was an Austrian botanist. HE studied at the Polytechnical Institute in Vienna and became substitute teacher at a high school in St. Pölten in 1869. He became full professor of natural history there upon obtaining his teaching certificate in 1871 and remained in this position until his retirement in 1900. He published his first agrostology papers on grasses in 1871 and soon became known as a world expert agrostologist on the grass family Poaceae. While he himself undertook only a single collecting trip - to Spain and Portugal he was charged with working up collections of grasses mainly from Japan Taiwan New Guinea Brazil and Argentina. Apart from agrostologisty systematics Hackel also contributed to the morphology and histology of members of the grass family. The genus Hackelochloa Poaceae is named for him. C.E. HUBBARD of RBG Kew was probably the foremost grass taxonomist of the twentieth century. First Edition. Half cloth and boards. Good. J.B. Metzler Hardcover
