Abstract
- A new species of Lauraceae,Cryptocarya kaengkrachanensisM.Z.Zhang, Yahara & Tagane, from Kaeng Krachan National Park, Phetchaburi Province, southwestern Thailand, is described and illustrated. This species is morphologically most similar toC. amygdalinain that its leaves are pinnately veined, leathery, and apparently glabrous (but microscopically hairy) abaxially, twigs are yellowish brown hairy, and fruits are 1.36 to 1.85 times longer than width. However,C. kaengkrachanensisis distinguished fromC. amygdalinain having the leaves of ovate and elliptic (vs. oblong-lanceolate) with leaf aspect ratio (length:width) from 1.38 to 2.28 (vs. 2.46–3.43), and ovoid fruits (vs. ellipsoid) with stalk distinctly swollen (vs. not or only slightly swollen). In addition, phylogenetic trees constructed based on internal transcribed spacer sequences (ITS) and genome-wide SNPs using MIG-seq showed thatC. kaengkrachanensisis not sister toC. amygdalinaand is distinct from all the otherCryptocaryaspecies hitherto recognized in Thailand. Analysis including other species demonstrates thatC. floribundashould be a synonym ofC. amygdalina, but we recognizeC. scortechiniias a distinct species.
