Lauraceae is among the largest and floristically most important woody plant families in subtropical and tropical zones. However, the Cenozoic fossil records of Lauraceae are mostly from mid-latitude regions. Here we described eight lauraceous species from the Oligocene of Ningming, Guangxi, South China on the basis of leaf compressions with cuticular structure, providing new evidence for high diversity of Lauraceae in the low latitude region of the northern hemisphere during the late Paleogene. The extant genera to which the Ningming Oligocene fossils are possibly closely related include Cinnamomum, Neolitsea, Litsea, Alseodaphne, Laurus, and Beilschmiedia. All of these extant genera except Laurus still exist in Guangxi today, whereas Laurus is currently distributed in the Mediterranean and adjacent regions. A cladistic analysis based on leaf architectural and leaf cuticular characters for Paleogene Lauraceae species in the world indicated a possible relationship between European and East Asian Paleogene species.

We studied leaf epidermal anatomy of Caryodaphnopsis Airy Shaw, a genus disjunct between tropical Asia and tropical America, using light microscope and scanning electron microscope. We sampled 10 species of Caryodaphnopsis and 52 species of other Lauraceous genera. Our observations suggest that this genus possesses a unique lower leaf epidermis. Compared with other leaves of Lauraceae, this genus has an additional layer covering the lower leaf epidermis and the stomatal apparatus. The additional layer is either closed or poriferous/reticulate. The outer periclinal walls of the lower leaf epidermis protrude outside forming hollow domes or columns, and the distal endings of these domes or columns are expanded and fused, which forms the additional covering layer. Three different types are recognized in the genus: (1) the middle portion of the protuberances is not contracted and the distal endings are free or adnate to each other, with only limited space between the two layers; (2) the middle portion is slightly contracted in the outer part, the distal endings are fused, with more space between the two layers; (3) the middle portion is conspicuously contracted and elongated into columns, the distal endings are fused and it is roomy between the two layers. The structure of the leaf lower epidermis is reconstructed and illustrated for the first time. This unusual leaf lower epidermis of Caryodaphnopsis is derived in Lauraceae and is an autapomorphic character. Outward protrusions of the outer periclinal walls forming papillate protuberances surrounding the stomatal apparatus are also found in a few other genera including Neocinnamomum, a genus closely related to Caryodaphnopsis, but the distal endings of these protrusions are not expanded and connected. We hypothesize that the periclinal wall of the lower leaf epidermis has been gradually modified in Lauraceae, from a smooth pattern in most genera, to papillate pattern (e.g. Neocinnamomum), and to the double layered lower leaf epidermis in Caryodaphnopsis. The origin and evolution of this unique lower epidermis might have been related to the climatic cooling and aridification since the late Eocene.

A phylogenetic analysis based on nuclear ITS and plastid trnK intron sequences confirms that Dahlgrenodendron, Sinopora, Triadodaphne, and Yasunia are members of the Cryptocarya group, as expected from morphology.\  Dahlgrenodendron from South Africa is sister to Aspidostemon from Madagascar. Triadodaphne inaequitepala is nested within Endiandra (both from Australasia), and Yasunia from South America is nested among South American Beilschmiedia species. Sinopora is a member of the Beilschmiedia clade, but its precise position is still uncertain.\  Among large genera of the group, Cryptocarya is clearly monophyletic, and Endiandra appears to be as well, if T. inaequitepala is included. Beilschmiedia is paraphyletic with respect to (at least) Potameia and Yasunia. Most well-supported clades within genera are geographically homogeneous, except a clade including the Chilean Cryptocarya alba and two New Caledonian species. Both Beilschmiedia and Cryptocarya have reached the Americas more than once.\  Four-locular anthers are plesiomorphic in the Cryptocarya group; two-locular anthers have arisen by fusion of the two pollen sacs of a theca. In the plesiomorphic fruit type, the ovary is completely enclosed in receptacular tissue; a superior fruit, seated free on its pedicel, is a synapomorphy of the Beilschmiedia clade.
