Abstract

The habitat of Solanum physalifolium Rusby (Solanaceae) is the dry valleys of the Andes Mountains at an elevation of 1,500∼3,500 m, where it is primarily distributed along streams or under the shade of small trees. It was confirmed that the species is sporadically and in small clusters distributed in fallow fields and vegetable farms in Songjeong-ri, Jinbu-myeon, Pyeongchang-gun, Gangwon-do, Republic of Korea in 2024. Based on observations in cultivated fields and their surroundings at an elevation of 600∼700 m, it is presumed that the main pathway of spread is through the introduction and establishment via contaminated crop seeds. This species can be distinguished from S. nigrum, S. nigrum var. humile, S. americanum by plant with densely glandular-pubescent hair and S. sarrachoides by the leaf blades 2∼6 ㎝ long, 1.4∼3.2 ㎝ wide and calyx lobe tips are not anthesis. Korean name is ‘Gin-teol-kka-ma-jung’ based on its densely glandular-pubescent hairs. We provide a detailed description, photographs, habitat details, and a taxonomic key to related taxa.
