| Abstract | In the semi-desert environment of the Mu Us Sandland, the vegetation is composed chiefly of shrubs and semi-shrubs, coverage normally amounting to 30–40%. However, an exception can be found in the community of Sabina vulgaris Antoine, an evergreen shrub, which tends to grow so densely that it covers the sand dunes completely. Previous research has indicated that the high density of Sabina is parallelled by the very low transpiration rate. Based on anatomical and scanning electronic microscopic observations, this paper also points out that two structural features should play an important role in the potential mechanism of water conservation in this plant. First, a low stomatal density in S. vulgaris can lead to a high stomatal resistance and low transpiration. Second, the morphological feature of S. vulgaris leaves being tightly pressed to the stems might be a structural feature of water conservation, because in this way the leaf side bearing more (and mostly larger) stomatal pores could be protected from direct high radiation, while the side with fewer (and mostly smaller) pores (the outer side) is exposed to the dry desert air. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
