AGRICULTURAL ECONOMICS AgEcon
Ruttan, Vernon W..
Agricultural economics is a field of applied economics. Its scope and its relationship to other social and natural science disciplines has changed over time in response to (a) the social, economic and technical changes impinging on the agricultural sector and (b) progress in economic theory and in other related social and natural science disciplines. The substance of agricultural economics in the United States at the present time can best be understood by reviewing the historical origins of the field and its recent evolution in relation to developments in economic theory, statistics and econometrics.

Albertus Seba's „Locupletissimi rerum naturalium thesauri...." (1734-1765) and the „Planches de Seba" (1827-1831) Naturalis
Holthuis, L.B..
INTRODUCTION The present note is the result of an investigation into the correct date of publication of the third volume of A. Seba's great work "Locupletissimi rerum naturalium thesauri. ..". In my own studies on Crustacea I accepted the year 1761 as correct, following in this Engelmann (1846) and the title page of the copy of Seba's book that I consulted. Dr. M. Boeseman, ichthyologist of the Rijksmuseum van Natuurlijke Historie, pointed out to me that in ichthyological literature the year of publication of this volume is practically always cited as 1758. Also Engel (1937) in his biography of Seba gave this later date. In trying to straighten this question out I obtained the most cordial help from Dr. Boeseman, Prof. Dr. H. Engel, former director of the...

An account of the genus Portulaca in Indo-Australia and the Pacific (Portulacaceae) Naturalis
Geesink, R..
In the introduction a brief historical review is given of the more important earlier treatment of the genus. In chapter 2, covering morphological observations, I have also inserted remarks on the systematic value of certain features. The axillary (and in sect. Neossia, nodal) hairs have often been interpreted as representing stipules. I have tried to advance arguments in order to show that their stipular homology is most unlikely. It is confirmed that there is no essential difference between the morphological structure of the inflorescence and that of the vegetative portion of the plant. There is no unanimity of opinion about the interpretation of the 2-whorled perianth; the outer series is often accepted to be of a bracteal nature. Von Poellnitz refers to...

An annotated key to the South-East Asiatic, Malesian, Mascarene, and African species of Myriophyllum (Haloragaceae) Naturalis
Meijden, R. van der.
The area of distribution of most Myriophyllum species is insufficiently known. In this paper, many new localities are recorded for 16 species from SE. Asia, Malesia, Madagascar, and Africa, and a key is added. One species from New Guinea, M. coronatum, is described as new (fig. I). Of the other species the synonymy is complete, but no descriptions are given; of each the distribution and ecology is cited, and if necessary critical remarks are added. Under the new species the second remark deals with the possible desirability of distinguishing subgenera or sections within the genus. It is concluded that, as the species show a reticulate affinity by parallelism, especially as regards reductions in both vegetative and sexual organs, the usefulness of...

An annotated list of the Acanthaceae collected by Miss W. M. A. Brooke on her travels in Bolivia Naturalis
Bremekamp, C.E.B..
The Acanthaceae collected by Miss W. M. A. Brooke in Bolivia are listed. Five new species are described, viz. Stephanophysum brookeae, St. macrandrum, Sarotheca glutinosa, S. boliviensis and Lophothecium boliviense. Moreover, for the species belonging to the group Genuini Ebracteolati of Dipteracanthus Nees a new genus Ulleria is created. The following new combinations are proposed: Ulleria geminiflora (Ruellia geminiflora H.B.K.), U. angustifolia (Dipteracanthus angustifolius Brem.), U. surinamensis ( D. surinamemis Miq.), and further Stemonacanthus euanthus (Ruellia euantha Lindau), Arrhostoxylum kuntzei (Ruellia kuntzei Lindau), Sarotheca archeri (Justicia archeri Leonard), S. cystolithosa (J. cystolithosa Leonard) and Saglorithys polygonoides (J....
