Inflorescences terminal, condensed racemes, 1–4 cm long, 4−12-flowered, pubescent. Flowers ca. 2 cm across; pedicels slender, 1−1.2 cm long, pubescent. Bracts triangular, 1.2–1.5 mm long, apex acuminate, margin ciliate persistent; bracteoles ovate-lanceolate, 0.5–0.7 mm long, apex acute, margin ciliate, persistent. Calyx 5-lobed, pubescent and glandular-hairy outside, glabrous inside; tube 1–1.5 mm long; lobes linear-lanceolate, 3−3.5 mm long, apex acute.

Stamens 4, didynamous, inserted at base of throat, slightly exserted; filaments white, slender, shorter pair 5−5.5 mm long, longer pair 8−8.5 mm long, connate at the base in pairs, glabrous; anthers white with a vertical violet-black band on the sides, oblong, 1.2–1.5 cm long, spurred at base, connective beyond the anther cells, glabrous. Ovary green, oblong or columnar, compressed, 1.2−1.5 mm long, papillose, basally surrounded by fleshy, dull white, nectariferous disc, 2-celled; ovules 2 in each cell; style white, filiform, 2.4–2.6 cm long, glabrous; stigma shortly 2-lobed, smooth. Capsules green, clavate, compressed, 1.4–2.2 cm long, dehiscent, densely glandular hairy. Seeds 4, suborbicular, flattened, ca. 3 mm across, tuberculate, rugose, dentate along margins, borne on ca. 2 mm long, hook-like retinacula. Phenology:—Flowering and fruiting from September to December. Habitat: — The new species grows along lakes in shady area at an elevation of about 10 m. The association includes Rivina humilis L., Ruellia tuberosa L., Cardiospermum halicacabum L., Mikania micrantha Kunth and Plumbago zeylanica L. and grasses etc. Distribution:—The species is distributed in Howrah, West Bengal, India so far. Etymology:—The new species is named after Dr Potharaju Venu, Former Senior Scientist of Botanical Survey of India, for his significant contribution to the taxonomy of Indian Acanthaceae. Notes:— The Indian species of the genus can be categorized in two groups on the basis of shape of corolla tube, i.e. Group 1 comprises three species Asystasia atroviridis Anderson (1867: 526), A. neesiana (Wallich 1830: 73) Nees (1832: 89), A. venui Anant Kumar, G. Krishna & Av. Bhattacharjee sp. nov. having cylindrical, shortly funnelshaped corolla tube upwards, and Group 2 having 10 species A. chelonoides Nees (1832: 89), A. crispata Bentham (1852: 647), A. dalzelliana Santapau (1948: 276), A. gangetica (Linnaeus 1756: 3) Anderson (1860: 235), A. indica H.J. Chowdhery & Av. Bhattacharjee (2006: 211), A. macrocarpa Nees (1832: 89), A. mysorensis (Roth 1821: 303) Anderson (1867: 524), A. pusilla C.B. Clarke (1889: 55), A. travancorica Beddome (1872: 39), and A. variabilis (Nees 1847: 165) Trimen (1895: 324) with tubular-ventricose corolla tube (FIGURE 1). Out of these, five species are endemic to India, e.g., A. crispata, A. dalzelliana, A. indica, A. pusilla, and A. travancorica. Lindau (1895) erected a new genus Asystasiella Lindau (1895: 326) to accommodate the species of Group one with two species, viz. A. neesiana and A. atroviridis, and it was considered to be different from Asystasia by having a narrow cylindric corolla tube and stachel pollen (spheroidal with spines). Ensermu et al. (1992) discussed the delimitation of the genus based on pollen morphology. Since, the genus Asystasia encompasses considerable variation in inflorescence form, corolla morphology, and pollen type, therefore, the genus Asystasiella was included within Asystasia (Manzitto-Tripp et al. 2022). The generic circumscription of Asystasia, Asystasiella, Mackaya and other related genera should be delimitated by molecular phylogenetic study along with pollen morphology. Das (1939: 408) incorrectly transferred these three species from Asystasia to Mackaya as M. atroviridis (Anderson 1867: 526) Das (1939: 448), M. macrocarpa (Nees 1832: 89) Das (1939: 447), and M. neesiana (Wallich 1830: 73) Das (1939: 447), respectively. However, the genus Mackaya is characterized by two fertile stamens without spurs and with two staminodes, while Asystasia has all four fertile stamens with spur at the base of anthers. Deng and Wu (2009: 308) stated that these three species were quite different from Mackaya in having four stamens and they preferred to place them in Asystasia rather than in Mackaya. Based on the above mentioned reasons the new species fits with Asystasia instead of Mackaya and hence, we are describing it here under Asystasia. The new species was wrongly identified as Asystasia chelonoides Nees by Chowdhery and Pandey (2007). However, it can be easily distinguished from Asystasia chelonoides by its long tubular-cylindrical corolla and densely flowered racemes. Comparison of diagnostic characters of the new species with its most allied species is provided in detail in Table 1. Additional specimens examined (Paratypes):— INDIA.

No full textThe priority for ideas and philosophy related to "Network Theory" have been traced back and documented by Braun(2004),and credit goes to Karinthy(1929).The IT has empowered to realise it, as the most practical phenomena and it is no more a humour. The OAI (Open Archives Initiatives)and ACIS (Academic Contributor Information System)are progressive in the direction ,which may lead to realise the "Collective Genius" at global level. Focus of present study is on Author-Self-Archiving (A-S-A)Metadata of the 983 Eprints in the Live Archives of the E-LIS (EPrints of Library and Information Science),which were approved till 7th July 2004.The A-S-A Metadata was used for librametric analysis. Self-explanatory bibliographics are illustrated.The highlights include: Conference papers (34%); highest approval, June 2004 (28%); published archives (76%);not refereed (52%); not in public domain (60%); highest self-archiving-author (De Robbio, Antonella).The Nos. of EPrints having single JITA domain specifications were: Theoretical and general aspects of libraries and information(27); Information use and sociology of information(80);Users,literacy and reading(13);Libraries as physical collections(30);Publishing and legal issues(57);Management(13);Industry, profession and education(36);Information sources, supports, channels(113) ; Information treatment for information services, Information functions and techniques (101); Technical services libraries, archives and museums(25); Housing technologies(1); Information technology and library technology(92); and Inter-domainery (395) i.e. having specifications of two or more than two JITA classes
Tourism in India / Gursharan Jeet Kaur and Gopal Kumar Johar
No full textIn 1947, immediately after independence, the focus of development in India was on key areas like agriculture, housing, industry, irrigation, infrastructure and other social sectors. So in the field of tourism, India has been a late starter and has started getting attention in the last two decades only. The phenomenal explosion of international and domestic tourism is an inevitable by-product of the prosperity that India has achieved in recent times. It been duly recognized in National Tourism Policy, 2002 that Tourism not only generates employment but also upgrades human skills. The infrastructure created for Tourism can be used by all other sectors of the economy. Therefore, development of Tourism must not be viewed in isolation and the states must adopt an integrated approach and action plan for its development. Presently, as far as approach for development of Tourism in India is concerned, there are many areas which lack emphasis like inadequate awareness about tourist spots, no surveys and studies relating these tourists spots, no norms and standards for the planning and development of these tourist spots, neglect of heritage tourism, neglect of traditional arts, craft & culture, ineffective marketing, inadequate tourism infrastructure etc. In this paper an effort has been made to highlight the present scenario of Tourism in India and hurdles that comes in the way for the development of Sustainable Tourism and its related infrastructure. It further highlights the initiatives taken by the Government itself, for attracting foreign incentives and to encourage private sector as well to act as a facilitator by providing supportive infrastructure facilities
