Cytomorphology, Geographical Distribution and Ethnobotany of Genus <i>Oxalis</i> Linn. from Western Himalaya (India)

Abstract

SummaryThe genus Oxalis belongs to the family Oxalidaceae and includes mostly wild as well as commonly cultivated ornamental plants. To generate basic information on genetic diversity required for the improvement of germplasm, the present study was carried out from the different areas of the Western Himalayas. During the study, eight accessions belonging to two species of the genus Oxalis were cytomorphologically observed. New intraspecific cytotypes in O. corniculata (2n=14) at world level and O. corymbosa (2n=14) at India level were reported. In comparison, these diploid and tetraploid cytotypes for O. corymbosa show significant variations in relation to morphology as well as geographical distribution on the world map. Further, the meiotic course in most of these accessions was observed to be normal except for one accession of O. corniculata marked with meiotic anomalies, directly influencing the pollen fertility.

Studies on Morphological and Quantitative Characters of Different Species of Oxalis Growing in Ranchi, Jharkhand

“…The plants were collected from natural growing habitat of different species after survey of localities around Ranchi in during the year of 2015-2016 using standard patterns [14,15]. The individuals of the species were taken from different places.…”

Morphology, Cytology and Ethnobotany of Three Pimpinella L. Species (Apiaceae) from the North-western Himalayas, India

“…The present results are comparable to earlier observations pertaining to many other flowering plant species such as Cassia demidiata , C. mimosoides var. wallichiana and Caesalpinia decapetala [20], Bupleurum lanceolatum [21], Epilobium angustifolium and Sium latijugam [22] (Jeelani et al 2017), Oxalis corymbosa [23], Dioscorea deltoidea [24].…”
