Their combination dimension, in Europe, has been envisioned at among 50 and a hundred thousands, and those are every year augmented at a swift price. every one specimen or dwelling plant includes a resource of facts and data represented either via the specimen itself and the linked info supplied by way of the collector and next investigators - identifications, box notes, documents of next study, and so on. This linked info is named the label information. learn at the taxonomy and geographical distribution of crops frequently calls for facts from specimens saved in a couple of associations in several countries.

In the past, the herbarium curator probably couldn't answer the problem well because there were 58 A. V. HALL too few records. Today, the curator cannot because there are too many. In this respect the herbarium could perhaps be seen as less of a data bank than a 'data crypt': because of no multi-indexing one must look for long hours for facts buried in a mass of irrelevant material. In fact, one seldom attempts problems that need large-scale multiindexing: they are too time-consuming. A computer-based informationmanagement system changes this position in a quite dramatic way.

The main objective is the production of a Flora of the same type as an ordinary good modern one. At the same time it could serve as a basis to create a data bank on the plants and the environments of Veracruz which could have many uses throughout the time of preparation of the Flora and afterwards. A brief discussion of the kinds of data that are being introduced in the data bank will be explained here. We will present a more ample discussion of the data from herbarium specimens. * Flora of Veracruz, Institute of Biology of of Botany of the Field prepare an ecological contribution number 15.

G. herbarium specimens or slides of diatoms, the set of descriptors under which the data for each item is to be entered. Within the data bank for anyone type of collection the descriptor set will need to be uniform throughout but it must be possible for it to vary between one type of collection and another. (ii) The entries must be free-field. It is impossible to predict in advance all the entries that it will be necessary to make under many of the descriptors, and if this cannot be done it is impossible to develop the system of coding required for fixed-field entries.
