Leaves opposite, decussate, petiolate or uppermost pair sessile; petioles (0−) 0.5−8 cm long, sulcate, pubescent; lamina elliptic-ovate to elliptic-lanceolate, uppermost pair ovate to broadly ovate, smaller in size, 1.4−10 × 0.9−4.4 cm, chartaceous, base unequal, rounded, subcordate, attenuate, or decurrent onto petiole when young, margin entire, apex shortly acuminate, pubescent and green above, tuberculate, glabrous and whitish beneath, veins camptodromous, midvein prominent, impressed above, prominent below, pubescent, lateral veins 5−7 pairs, otherwise same as mid vein. 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. Corolla infundibuliform, ventricose, white, with a light violet-purple blotch on the middle lobe of lower lip, glandular-hairy outside, glabrous inside; tube 2–2.3 cm long, base cylindrical for 1.5–1.7 cm long, throat 5–6 mm long; lobes 5, elliptic-ovate, 5−7 × 4–4.5 mm, apex obtuse. 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.

Remembering Daya Krishna and G. C. Pande: Two Giants of Post-Independence Indian Philosophy
No full textDaya Krishna was the public face of Indian philosophy in the first half-century after Indian independence. Nobody on the Indian scene in that period came close to him in influence or in contribution to the profession. Nobody else in the world thought as hard or as fruitfully about the relation of Indian philosophy to that of the rest of the world, and nobody else dared to think as creatively and even as heretically about the history of Indian philosophy itself. This special issue of Philosophy East and West commemorates G. C. Pande and Daya Krishna as philosophers. But we would be remiss if we were not to acknowledge that Pande was also an elegant poet, both in Hindi and in Sanskrit. In this article, the authors have continue the dialogue that Krishna and G. C. Pande initiated between the argumentative and the spiritual, the skeptical-individualistic and the traditional-communitarian styles of thinking, self-critical and culture-sensitive on all the practical and theoretical problems that haunt human rationalities and relationships
Colocalization of the Ganglioside G(M1) and Cholesterol Detected by Secondary Ion Mass Spectrometry
No full textThe characterization of the lateral organization of components in biological membranes and the evolution of this arrangement in response to external triggers remain a major challenge. The concept of lipid rafts is widely invoked; however, direct evidence of the existence of these ephemeral entities remains elusive. We report here the use of secondary ion mass spectrometry (SIMS) to image the cholesterol-dependent cohesive phase separation of the ganglioside G(M1) into nano- and microscale assemblies in a canonical lipid raft composition of lipids. This assembly of domains was interrogated in a model membrane system composed of palmitoyl sphingomyelin (PSM), cholesterol, and an unsaturated lipid (dioleoylphosphatidylcholine, DOPC). Orthogonal isotopic labeling of every lipid bilayer component and monofluorination of G(M1) allowed generation of molecule specific images using a NanoSIMS. Simultaneous detection of six different ion species in SIMS, including secondary electrons, was used to generate ion ratio images whose signal intensity values could be correlated to composition through the use of calibration curves from standard samples. Images of this system provide the first direct, molecule specific, visual evidence for the colocalization of cholesterol and G(M1) in supported lipid bilayers and further indicate the presence of three compositionally distinct phases: (1) the interdomain region; (2) micrometer-scale domains (d > 3 mu m); (3) nanometer-scale domains (d = 100 nm to 1 mu m) localized within the micrometer-scale domains and the interdomain region. PSM-rich, nanometer-scale domains prefer to partition within the more ordered, cholesterol-rich/DOPC-poor/G(M1)-rich micrometer-scale phase, while G(M1)-rich, nanometer-scale domains prefer to partition within the surrounding, disordered, cholesterol-poor/PSM-rich/DOPC-rich interdomain phase
Water-saving Rice Production Technologies in Krishna Western Delta Command of Andhra Pradesh – An Economic Analysis
No full textThe economic analysis of water-saving rice production technologies, viz. system of rice intensification (SRI), semi-dry and rotational irrigation vis-Ã -vis farmers’ practice has been carried out based on the study executed in Modukuru pilot area of Guntur district of Andhra Pradesh. Among the three water-saving rice production technologies analyzed, the total cost of cultivation has been recorded highest in SRI (Rs 58645/ha), followed by rotational (Rs 47140/ha) and semi-dry (Rs 39321/ha). But, the per hectare yield has been found highest in SRI (6.85 t), followed by semi-dry (6.66 t) and rotational (6.2 t), inferring that all the three technologies have recorded higher yields over farmers’ practice of 5.5 t/ha. However, the net returns and B-C ratio are maximum in semi-dry (Rs 43,484/ha; 1.11), followed by rotational (Rs 30,085; 0.64) and SRI (Rs 26,466/ha; 0.45) methods. Similarly, the water-use efficiency has been found highest in SRI (8.53 kg/ ha-mm), followed by semi-dry (8.02 kg/ha-mm) and rotational (7.33 kg/ ha-mm) methods, while the water-use efficiency benefit (Rs/ha-mm) has been recorded maximum in semi-dry (52.39), followed by SRI (42.08) and rotational (35.56) methods. With the initiation of Andhra Pradesh Water Management Project, Bapatla, the area under semi-dry rice cultivation has been found increasing over a period of four years, from 0.6 ha in 2004-2005 to 22 ha in 2007 -2008.Agricultural and Food Policy,
