The introduction, occurrence and distribution of wild populations of Sesamum radiatum Thonn. ex Hornem. in India along with taxonomic notes on the nomenclature and identification of the species have been discussed in detail. The earlier reports of the taxon from Eastern & Western Ghats and elsewhere due to errors in identifications clarified and a field key furnished to facilitate the correct identity. Color photographs of the plant parts are also provided for easy field identification. The present collection from the West Coast of Kanniyakumari district forms an addition to the flora of Tamil Nadu and to the strand flora of India as well.

<p>Precipitation distribution around an orographic barrier is controlled by the Froude Number (Fr) of the impinging flow. Fr is essentially a ratio of kinetic energy and stratification of winds around the orography. For Fr > 1 (Fr <1), the flow is unblocked (blocked) and precipitation occurs over the mountain peaks and the lee region (upwind region). While idealized modelling studies have robustly established this relationship, its widespread real-world application is hampered by the dearth of relevant observations. Nevertheless, the data collected in the field campaigns give us an opportunity to explore this relationship and provide a testbed for numerical models. A realistic distribution of precipitation over a mountainous region in these models is necessary for flash-flood and landslide forecasting. The Western Ghats region is a classic example where the orographically induced precipitation leads to floods and landslides during the summer monsoon season. In the recent INCOMPASS field campaign, it was shown that the precipitation over the west coast of India occurred in alternate offshore and onshore phases. The Western Ghats received precipitation predominantly during the onshore phase which was characterized by a stronger westerly flow. Here, using the radiosonde data from a station over the Indian west coast and IMERG precipitation product, we show that climatologically, these phases can be mapped over an Fr-based classification of the monsoonal westerly flow. Classifying the flow as 'High Fr' (Fr >1), 'Moderate Fr' ( 0.5 < Fr ≤ 1) and 'Low Fr' ( Fr ≤ 0.5 ) gives three topographical modes of precipitation -- 'Orographic', 'Coastal' and 'Offshore', respectively.  Moreover, these modes are not sensitive to the choice of radiosonde station over the west coast.</p>

Market Towns

The Periplus Marts Erythræ describes the seaports below Barygaza in the following way according to Schoff's translation: “The market-towns of this region are, in order, after Barygaza: Suppara, and the city of Calliena, which in the time of the elder Saraganus became a lawful market-town; but since it came into the possession of Sandares [an unjustified conjecture for the text's Sandanes] the port is much obstructed, and Greek ships landing there may chance to be taken to Barygaza under guard. Beyond Calliena there are other market-towns of this region; Semylla.…” Suppara is now Sopara on the coast above Bassein, Semylla is Cemūla of two inscriptions, now Chaul, and Calliena is Kalyāṇa. This last, situated at the foot of the two regular ascents of the Western Ghats leading towards Nasik and Poona respectively and with good access to the sea, was the natural outlet for the commerce of the Andhra dominions on the west coast, and the notice, just quoted, shows how its trade was stifled, as the Kṣaharātas extended their rule southwards from Broach. It is unnecessary here to consider who are the kings alluded to in this passage or in the earlier one mentioning Nambanus (a conjecture for the text's Mambarus), but clearly we are dealing with the rivalry of the Western Satraps and the Andhra kings. That the former were successful in their policy towards Kalyāṇa is shown by Ptolemy's omission of the town. The order he gives (taking Renou's text) is Souppara mouth of the River Goaris, Dounga, mouth of the River Bêndas, Semyla.

The Western Ghats

Free intercourse with Malabar was long denied to the rest of Southern India by the formidable natural obstacle of the Western Ghats with their impenetrable fastnesses and few passes. Owing chiefly to this circumstance that part of the country remained to a great extent isolated and secure from frequent invasions by other southern powers. This isolation, coupled with the conservative nature of the people of this tract, accounts for the preservation intact of several ancient customs of the Indians. Even in later times, whenever there had been any general disaster affecting the whole of the Dekhan, such as an invasion by the Muhammadan kings of the Khilji and Taghlak lines, the west coast afforded a safe asylum to the rest of the south. There is nothing unnatural in the following exclamation of the poet-composer of the Tiruvālaṅgāḍu plates of the eleventh century a.d.:—“Excepting Paramēśvara, who else in this world could contemplate even in mind the humiliation of that country which is protected by the glory of the crest jewel of the Bhrgu race (i.e. Paraśu-Rāma) and the austerities of its chiefs, and which had not been injured by enemies.”

At the foothills of the formidable Western Ghats of India lies a coastal strip of land, the Konkan Coast, which forms part of the extended coastline along the west coast of the country. The unique culture found in the Konkan coastal landscape has produced a magnificent ornamental style named Kaavi Kalé. Kaavi, or kavé, means in this context “red oxide”, while kalé means “art form”. It is fundamentally an incised work performed on an architectural surface that has been previously finished with lime plaster and then a red oxide layer over it. This forms elaborate murals and motifs inspired by the unique folklore of Dravidian culture. Although predominantly found in Hindu temples, this secular art form can also be seen in churches, a mosque, Jain temples and folk deity temples, as well as in domestic architecture. This paper presents the history of the art form, its techniques, a brief iconographic study of its compositions and possible methods of conservation, through accounts of extensive primary surveys and on-site experiments and a study of secondary sources.
