A new species of Lauraceae, Cryptocarya kaengkrachanensis M.Z. Zhang, Yahara \& Tagane, from Kaeng Krachan National Park, Phetchaburi Province, southwestern Thailand, is described and illustrated. This species is morphologically most similar to C. amygdalina in 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. kaengkrachanensis is distinguished from C. amygdalina in 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 that C. kaengkrachanensis is not sister to C. amygdalina and is distinct from all the other Cryptocarya species hitherto recognized in Thailand. Analysis including other species demonstrates that C. floribunda should be a synonym of C. amygdalina, but we recognize C. scortechinii as a distinct species.

The family Lauraceae is a major component of tropical and subtropical forests worldwide, and includes somecommercially important timber trees and medicinal plants. However, phylogenetic relationships within Lauraceae have long been problematic due to low sequence divergence in commonly used markers, even between morphologically distinct taxa within the family. Here wepresent phylogenetic analyses of 43 newly generated Lauraceae plastomes together with 77 plastomes obtained from GenBank, representing 24 genera of Lauraceae and 17 related families of angiosperms, plus nine barcodes from 19 additional species in 18 genera of Lauraceae, in order to reconstruct highly supported relationships for the Lauraceae. Our phylogeny supports the relationships: sisterhood of the Lauraceae and a clade containing Hernandiaceae and Monimiaceae, with Atherospermataceae and Gomortegaceae being the next sistergroups, followed by Calycanthaceae. Our results highlight a monophyletic Lauraceae, with nine well-supported clades as follows: Hypodaphnis clade, Beilschmiedia\–Cryptocarya clade, Cassytha clade, Neocinnamomum clade, Caryodaphnopsis clade, Chlorocardium\–Mezilaurus clade, Machilus\–Persea clade, Cinnamomum\–Ocotea clade, and Laurus\–Neolitsea clade. The topology recovered here is consistent with the patterns of plastome structural evolution and morphological synapomorphies reported previously. More specifically, flower sex, living type, inflorescence type, ovary position, anther locus number, leaf arrangement, leaf venation, lateral vein number, tree height, and inflorescence location all represent morphological synapomorphies of different lineages. Our findings have taxonomic implications and two new tribes, Caryodaphnopsideae and Neocinnamomeae, are described, and the composition of four other tribes is updated. The phylogeny recovered here provides a robust phylogenetic framework through which to address the evolutionary history of the Magnoliids, the third-largest group of Mesangiospermae.

The homonymy of some fossil and extant species names of Cinnamomum is resolved. Cinnamomum gracile (Geyler) Ettingshausen (fossil) is replaced by a new name C. camphoricum nom. nov., because of the earlier homonym C. gracile Miquel (extant); C. costulatum nom. nov. is proposed to replace the later homonym C. apiculatum Saporta (fossil fruits) non C. apiculatum Pilar (fossil leaves); C. fajumicum nom. nov. is proposed instead of C. africanum Engelhardt (fossil) non C. africanum Lukmanoff (extant); C. kalbaricum nom. nov. instead of C. grandifolium Cammerloher (extant) non C. grandifolium (Ettingshausen) Schimper (fossil); C. weddellii nom. nov. in place of C. orbiculatum Lukmanoff (extant) non C. orbiculatum Saporta (fossil). Cinnamomum camphoricarpum sp. nov. is validated instead of the invalidly published C. macropodum Miki (lacking holotype designation when published) based on fossil fruits and seeds from Pliocene sediments of Japan. Cinnamomum goeppertii Ettingshausen is rehabilitated as a legitimate substitute for Daphnogene javanica G\öppert,
because the combination C. javanicum (G\öppert) van Konijnenburg-van Cittert, van Waveren \& Jonkers is illegitimate due to the existence of an earlier homonym, C. javanicum Blume (extant). Pterospermum wilkieanum nom. nov. (Malvaceae) is proposed instead of P. gracile Wilkie (extant) non P. gracile Geyler (fossil) (\≡ C. gracile (Geyler) Ettingshausen). Cinnamomum salicifolium (Nees) Kostermans and C. trinerve (Lundell) Kostermans (extant) were found to be later illegitimate homonyms of fossil-species, C. salicifolium Staub and C. trinerve Bell respectively. Furthermore Cinnamomiphyllum Nathorst, Daphnogene grandifolia, D. lanceolata, Cinnamomum broteroi, C. orbiculatum, C. salicifolium Staub (non (Nees) Kostermans), C. trinerve Bell (non (Lundell) Kostermans), and C. ucrainicum are lectotypified. New combinations are validated: Cinnamomoides broteroi comb. nov., C. ellipticum comb. nov., C. humei comb. nov., C. jordanicum comb. nov., Cinnamomum duabicum comb. nov., Neolitsea marginata comb. nov., N. pannonica comb. nov., N. staubii comb. nov. As an addition to Taxonomic Literature II records, the precise dates of publication of the taxonomic works of G\öppert\’s Die Terti\ärflora auf der Insel Java (1854), Lukmanoff\’s Nomenclature et iconographie des Canneliers et Camphriers (1878, not 1889), Ettingshausen\’s Beitrag zur Kenntnis der Terti\ärflora der Insel Java (1883) and Zur Terti\ärflora von Borneo (1883, not 1884) are established here.
