not these precise numbers aid you in the classification or not is a question of how you use it and how you put it together, you see. (Craig) What are we aiming at in the end with chemotaxonomy and cytotaxonomy? (Dave) More information about the plant. (Craig) We are always looking for more information, but why, why are we looking for it? This is my , I'm not getting my point across to you. To me the end product if we could get it, you can't get it perfectly, but if we could get it would be an understanding of how life evolved, plants evolved and the relationships that developed along the way. (Bob) Don't you want …

suggest that the investigator describe the cultivar on the basis of as many of the characters given in Table 1 as are available. Having described the plant with the characters given, proceed to Fig. 3, which gives the major categories. Following discovery of the major subdivision to which a cultivar belongs (i.e., rough-rooted, obovate lobed leaves), one then recognizes that the unknown plant belongs to one of twelve groups (Fig. 3). Within the groups

… and as such it is accepted by... in the Flora SSSR. It has, however, an older name at the species level, since it was described as Golu japonica by Chevallier (1902). The chromosome number of the European plant has been determined by Hapgood (1941), Lise (1954), and Hildreth (1955), who all determined the value 2n=48 in different Siberian Populations. The value for the Pacific plant remains unknown, whereas the present writers have counted 2n=96 chromosomes in material from the Bering Peninsula and from the Lancashire mountains. The population from the Japanese locality belongs to the var. sublyrata, whereas the …

Dr. Jose de Js. Jimenez - 2 - May 9, 1966 is a good example of a genus of plants that has never been well classified. We are attempting to use computers to aid us in the formation of a classification which can be useful to taxonomists. In Manihot, the species M. esculenta is one which is very difficult to classify because of its wide cultivation, and extreme variability. We hope the computer will aid us in making a good classification of this cultivated species. This is the sense of the terms "quantitative taxonomy." It merely is a set of words for which many synonyms exist. I trust that this description is meani …

… cultivated wheats are the most conspicuous example of this evolution of polyploidy. It is the only known mechanism by which new true-breeding species can be created almost overnight. Since different wild grasses have been involved in wheat's evolution, the species differ not only in the number but also in the nature of their chromosomes. Relationships of different sets of chromosomes are determined by studying the degree of chromosome pairing in the reproductive cells of hybrids. If the pairing is complete, or almost so, the chromosome sets (or genomes) of the parents are regarded as identical or closely related.

Goodspeed, Division of Botany Plant Science Building University of California Berkeley, California. Dear Goodspeed: Gradually during the past few years I have been accumulating a collection of species of Ficus. Root tips have been secured from the potted plants and I now have slides showing chromosome numbers for 49 or 50 species not yet reported on. I hope to get some photographs of chromosome complements of a few of these species some tim …

Cotton (Gossypium. (Generic Char.) So. Pacific Ry., 10-9-16. p.235 Although the linnaean sexual system of classification of plants is no longer followed or taught, it still governs very largely the methods and standpoints of systematic work. Nobody questions the fact that floral characters are of very great significance as indicating the relationship of plants, there is increasing recognition of the fact that the significance of floral differences is not the same in the different groups of plants. Some families show great similarity in the forms of flowers, and others great diversity. There is more and more of a …

page 5 where within a limited locality such as southern Greece, people made classifications and their classifications would be on life form essentially to start with. That is, some of the earlier classifications divide plants on the basis of trees, shrubs, and herbs. And for that particular locality, such a classification would have some sort of merit. In other words, you could put a plant into some package or other. If you moved from that particular area, as frequently as people might have, and tried to use the same sort of classification, we might discover that we had some discontinuities that would fit into su …

Chromosome numbers of Yugoslavian plants. I. by Åskell Löve and Franc Sušnik, Department of Environmental, Population and Organismic Biology, University of Colorado, Boulder, Colorado 80302, U.S.A., and Institute of Biology, University of Ljubljana, YU-61001 Ljubljana, Yugoslavia. Abstract. Chromosome counts are given for Yugoslavian material of the following 25 taxa, with some remarks on their taxonomy and distribution: Crocus malyi Vis. (2n = 30); Iris macedonica Horvat (2n = 48); Colchicum arenarium W. & K. (2n = 54); Colchicum hungericum Janka (2n = 52); Colchicum doerfleri Halacsy (2n = 54); Colchicum visian …

… . In addition to the above methods of group assignment, the investigator will be aided by examination of the data given in Tables 2 and 3. These tables relate the stem colors to the root colors. Generally, plants with brown, dark brown, or reddish-brown stems are rough-rooted, and plants with light brown, tan or light tan stems have smooth-surfaced roots. Those plants whose stem color vary from these states are indicated in Tables 2 and 3, so that these can be assigned to the major categories given in Fig. 3. Since the objectives of this classification are to show relationships that might be useful for plant bree …

we understand its place in evolution, emphasis ought to be made to define all species and their lower units exactly and biologically, by aid of intrinsic characteristics. For this, chromosome studies and other cytotaxonomical methods are important. In vascular arctic plants and mosses such studies have already given considerable, though still incomplete results. The cytology of lower plants and of animals of the arctic lands is, however, very little known. Arctic and alpine regions

Nous commissaires nommés par l'Académie avons lu et examiné un Mémoire de M.... de Jussieu intitulé "Examen de la famille du Renouée". Dans ce mémoire m.... de Jussieu ayant comparé les rapports des plantes avec les affinités chimiques, malgré la très différence qu'il y a entre ces 2 choses, prend la Botanique d'origine. D'abord il examine comment les Botanistes s'y sont mis pour classer les plantes; il remarque que les uns préfèrent le fruit, les autres la fleur, Saint-Lacoste, c'est-à-dire, les Étamens peuvent tirer leurs caractères, les autres font pour classiques, en on fait des systèmes où des espèces de not …
