“…Herein we amend the description based on herbarium specimens examined by us and on our field observations of I. goughii at various localities in the southern Western Ghats. Arya et al (2021) and Mohan et al (2021) described I. danii and I. raktakesara , respectively, as new species, and distinguished them from I. goughii by few marginal characters, but we did not find their cited type specimens at CAL and MH. Based on the descriptions and illustrations given in protologues of I. danii and I. raktakesara , we find both to be conspecific with I. goughii .…”

Morphological variation in Impatiens goughii (Balsaminaceae) from different areas of the southern Western Ghats, India, is studied and discussed, including an amended morphological circumscription of the taxon. An epitype and a lectotype are designated for I. goughii, and I. danii, I. omissa, I. parvifolia and I. raktakesara are synonymized with it. Additionally, lectotypes are designated for I. anamallayensis and I. microtheca.

“…Nayar et al (2014) enumerated 106 taxa of Impatiens from the Western Ghats of which 97 are exclusive endemics. More than 30 species have been discovered from various parts of the Western Ghats during the last 10 years (Kumar et al 2011;Dessai & Janarthanam 2011;Narayanan et al 2011Narayanan et al , 2012aNarayanan et al ,b, 2013Hareesh et al 2015a;Prabhukumar et al 2015aPrabhukumar et al ,b, 2016Prabhukumar et al , 2017Ramasubbu et al 2015aRamasubbu et al ,b, 2017Ramasubbu et al , 2020aChhabra et al 2016;Bhaskar & Sringeswar 2017;Manudev et al 2017;Mani & Thomas 2017;Mani et al 2018Mani et al , 2020Arigela et al 2019;Salish et al 2019;Subbiah & Vellingiri 2019;Vishnu et al 2020Vishnu et al & 2021Arya et al 2021). Impatiens species are usually seen in open, wet grasslands and rocky hill slopes at higher elevations and are highly sensitive to micro-climatic conditions.…”

Impatiens megamalayana is a recently described balsam from the Megamalai hills of the Western Ghats in Tamil Nadu state. This is a small, annual herb with ridged stem, often distributed in open, wet, rocky grasslands above 1,000 m elevation. The plant considered endemic to the Megamalai hills of Tamil Nadu is recently located in the Urumbikkara hills of Idukki district in Kerala state, which is about 120 km away from its original locality. Urumbikkara is an emerging tourist destination in central Kerala and the newly located populations of the plant are outside protected forest areas and are facing severe threat due to anthrapogenic activities. A detailed description, photographs and distribution maps are provided to facilitate easy identification of the plant in the field. An updated checklist of the genus Impatiens in Kerala state is also furnished for future reference.

“…Impatiens Linnaeus is the largest genus in the Balsaminaceae family, containing approximately 1000 species with new species discovered constantly [1][2][3]. It is known for its high variability of traits [4][5][6][7][8], but also widespread distributions [9], with annual or perennial cycles of growing [10,11].…”

Pollination biology in the widespread species Impatiens capensis Meerb. has only been studied in America, specifically in zones of the U.S.A. and Canada. In this study, we investigated the pollination biology of I. capensis using an integrative identification approach using morphological and molecular tools in four populations of Northwest Poland. We also determined and compared the functional characteristics of the pollinators of the introduced species from the study sites and the native ones reported, for the latter collecting information from bibliographic sources. Visitors were identified using standard morphological keys, including identifying and classifying insect mouthparts. Molecular identification was carried out using mitochondrial DNA’s cytochrome oxidase subunit I (COI). We morphologically identified 20 species of visitors constituted by 17 pollinators and three nectar robbers. DNA barcoding of 59 individuals proved the identification of 18 species (also 18 BINs). The frequency of pollinator species was primarily made up of representatives of both Hymenoptera (75%) and Diptera (21%). The morphological traits, such as the chewing and sucking mouthparts, small and big body height, and robber and pollinator behavior explained mainly the native and introduced visitors’ arrangements that allow pollination success. However, to understand the process comprehensively, further investigation of other causalities in pollination success and understanding the diversity of pollinators in outer native ranges are necessary.
