A new scapigerous species of <i>Impatiens</i> (Balsaminaceae) from India

Abstract

Impatiens minae Ratheesh, Anil Kumar & Sivad. a new scapigerous species of Impatiens from Wayanad district in Kerala, India is described and illustrated. The new species resembles Impatiens denisonii and I. scapiflora by its 3-lobed lateral united petals and lower sepal with a long spur; but differs from the latter in having a curved band of dense fleshy clavate papillae at the base of lateral united petals, and from the former in the absence of a dorsal filiform appendage or auricle at the base of the lateral united petals.

<i>Impatiens bhimgadensis</i> (Balsaminaceae), a New Species from Karnataka, India

“…Rhodolith beds provide habitat for many associated invertebrates and macro-flora and are recognized as environmental recorders 3 as they contribute in palaeoclimatic reconstructions over a broad range of temporal and spatial scales 4 . These coralline algae produce growth bands with a morphology and chemistry that record environmental variation 3 .…”

How distinct is Impatiens hookeriana Arnott from I. grandis Heyne (Balsaminaceae)?

“…Impatiens shows restricted distribution in five hotspots viz., Southeast Asia and southwestern China, eastern to central Himalayas, southern India, tropical Africa and Madagascar (Grey-Wilson, 1980). From the establishment of the genus to till now several botanical researchers made extensive contributions on collection, identification and documentation along with new species in India (Bhaskar 1975, Vivekananthan et al 1997, Swaminathan et al 2001, Pusalkar & Singh 2010, Dessai & Janarthanam 2011, Narayanan et al 2011, 2012, Bhaskar 2012, Ramasubbu et al 2015a,b, Bhaskar & Sringeshwara 2017, Mani & Thomas 2017, Ramasubbu et al 2017, Mani et al 2018, Salish et al 2019. From their distribution pattern, it seems probable that the scapigerous balsams of India originated from the North of Palghat gap (Kerala) and caulescent pedunculate species from the southern India (Barnes 1939, Bhaskar 2012.…”

<i>Impatiens theuerkaufiana</i> (Balsaminaceae), a new scapigerous species from the Western Ghats, India

“…Interestingly, more than 90 species of Impatiens are endemic to the Western Ghats including the new species described by Chandrabose (1979), Bhaskar & Razi (1983), Chandrabose et al (1984), Kumar & Sequiera (1996, 2001, Bhaskar (2006), and Dessai et al (2009). In India, there are about 20 known scapigerous species of Impatiens and are restricted to the same area which belongs to the Western Ghats-Sri Lanka Biodiversity Hotspot (Vivekananthan et al 1997, Viswanathan & Manikandan 2003, Bhaskar 1981, 2006, Narayanan et al 2011. Brief accounts on the history of studies of Indian species of Impatiens have been provided by Narayanan et al (2011) and Dessai & Janarthanam (2011).…”
