- Abstract
Impatiens longshanensis (The LSID for the name Impatiens longshanensis is: 77219154-1) sp. nov. and I. lihengiana (The LSID for the name I. lihengiana is: 77219153-1) sp. nov., from Hunan, China, are described and illustrated here. The molecular phylogenetic study suggests that I. longshanensis and I. lihengiana should be placed in the I. sect. Impatiens. A detailed description, diagnostic characters between the two new species and allied species, pollen and seed morphology, and color photographs are provided. In addition, based on wide sampling, we found that the longifilamenta group, an endemic group to China, whose members have basal lobes of lateral united petals with long filamentous hairs, shows significant morphological variability. In this paper, we discuss the taxonomic significance of morphological characteristics within this group. Based on a literature review and observation of living materials in the field, an updated identification key for this group is also proposed.
