Abstract

The genus Melocanna is distributed in Bangladesh, Burma and India, and consists of two species viz. M. humilis Kurz and M. baccifera (Roxb.) Kurz. The name of the Burmese species M humilis was preoccupied for a species of Cochin-China. Therefore, Parkinson renamed the Burmese species as Melocanna arundina Parker which is the correct name.

Abstract

Forests on northern and southern aspects at Siahi Devi hill of West Almora Division in Kumaun Himalayas were quantitatively analysed. Three forest types, viz. Pinus roxburghii at hill base (1,250-1,500 m), mixed oak-pine at higher altitude (1.750 m) and Quercus leucotrichophora at hill top (2.000-2.200 m) were recognized on northern aspect. Forests on southern aspect were categorized only into two types. Viz. P. roxburghii upto 2,000 m and mixed oak-pine at hill top (2,200 m). The composition of tree layer among the forests differed markedly on northern aspect whereas it was considerably similar on southern aspect. Shrub layer indicated dissimilarity among forests on both the aspects. Tree species richness and diversity were maximum in Q. leucotrichophora forest on northern aspect and in oak-pine forest on southern aspect. Concentration of dominance showed an inverse relation with diversity Q. leucotrichophora indicated fair regeneration potential in the studied forest sites. P. roxburghii exhibited faster regeneration than Q. leucotrichophora and it may expand replacing the latter tree Species.

Abstract

Within the limits of the Flora, Brit. Ind. Silybum marianum (L.) Gaertn. (Compositae) has been recorded from West Punjab, Hazara, Peshawar, Jammu and Kashmir. Afterwards, it has occasionally been collected from Chamba and Kulu. Recently it has been found to be naturalising in the Doon Valley on few localised spots. Its sporadic occurrence abruptly in Dehra Dun has been attributed to the possibility of its seeds having accompanied the immigrants from West Punjab, etc., who have settled around the place where it is now spreading. There is similar instance of Lepidium perfoliatum L. recorded before, where the plant, otherwise native of Afghanistan and Baluchistan has been suddenly found growing in Dehra Dun.

Abstract

The paper records the occurrence of Gloehidion montanum Thw., a tree of the family Euphorbiaceae, in India. It was collected from forests of Goa in the Western Ghats. So far, the species was considered endemic to Sri Lanka. Brief notes on nomenclature, description, infraspecific and interspecific differences, phytogeography, a key for identification and an illustration are provided.

Abstract

Time seems to be right for Indian libraries and information centres to join networks in greater numbers to overcome the issues such as budget constraints, information explosion, increase in cost of publications, and to utilize information available in machine-readable form worldwide. Telematics, the newly developed information technology - a combination of computers with telecmmunications - has been considered to be very promising technology for computer networking. Applications of Telematics in computer networking and its components have been discussed. Benefits of computer networking in terms of resource sharing, speed of information retrieval, retrenching the limit of the distance, etc. have been highlighted. Further experiences of Central Road Research Institute (CRRI), New Delhi, a premier R&D organisation engaged in a wide variety of research programmes on highway engineering and related subjects, using its own Local Area Network and other two networks, viz., DELNET and SIRNET have been discussed in terms of hardware, communication softwares, LAN components and utilities (e.g. peer to peer communication and E-mail). The use of LAN with client server architecture, its potential benefits in library automation such as inter-library loan, quick reference, catalogue search facility through E-mail, file transfer and correspondence with member libraries, and problems, namely, non-availability of databases at member libraries, standardization of information, security, limited staff and cost of hardware and software have been discussed in particular for library and information applications.
