The covering tissue structure is important for leafless stem succulents, influencing their photosynthetic activity. Usually, the epidermis on succulent stems persists a long time, making photosynthesize as possible. Its persistence implies maintaining continuity of tissues during bark dilatation. In most plants, dilatation performed by developing periderm(s) to replace epidermis. ways with delay periderm formation remain poorly known. present study, we examine juvenile and mature pencil tree...
Abstract Background and Aims Annuals produce little wood due to their short life cycle, while perennials can accumulate more, though not all do. Consequently, lifespan extension is a prerequisite for—but synonymous with—secondary woodiness. Even if shift perenniality does substantially increase production, it may still affect anatomy, as annuals prioritise rapid growth, whereas invest in structural resilience. Heliophila, genus of the Brassicaceae from Cape Floristic Region, provides an...
Abstract Dorema, Ferula and Leutea are genera of Apiaceae tribe Scandiceae, subtribe Ferulinae. Their placement in Scandiceae was established based only on nuclear ribosomal DNA internal transcribed spacer (nrDNA ITS) sequence variation. Previous molecular studies suggested that Dorema nested within Ferula. To confirm relationships eventual nomenclatural changes, we increased taxonomic sampling examined nrDNA ITS three noncoding cpDNA markers: rpoB‐trnC intergenic rps16 rpoC1 introns....
Fossil wood of Chinese white pine (Pinus armandii Franch.) from the Late Pleistocene deposits Maoming Basin South China provides first megafossil evidence for glacial expansion range a cold-tolerant species in low latitudes.
The aim of this study was to identify major clades in the economically important and taxonomically difficult genus Ferula (Apiaceae tribe Scandiceae subtribe Ferulinae) provide a classification framework. Phylogenetic relationships among 126 spp. eight species its sister Leutea were evaluated based on nuclear ribosomal (nr)DNA ITS three plastid regions: rps16 intron, rpoC1 intron rpoB-trnC intergenic spacer. One hundred fifty-three accessions considered including type specimens seven...
The Pleistocene Epoch, marked by significant climatic fluctuations and glaciations, profoundly impacted plant populations. However, our understanding of the influences last glaciations on tropical-subtropical flora vegetation remains limited due to insufficient data. Here, we present mummified wood Magnolia insignis (Wall.) Bl. from Upper (33–30 ka cal. BP) Maoming, South China, providing direct evidence a broader historical range for this species during period prior LGM in glaciation....
Floral morphology and vascular anatomy in members of the Asian Schefflera clade (Araliaceae) are studied. This is special interest because secondary loss flower groundplan stability increase merism. Among five species studied, three have isomerous pentamerous flowers, one has (almost) polymerous nonisomerous flowers as a result increased carpel number. Loss calyx innervation reduction sepals suggested apomorphic for subclade Heptapleurum s.l. Tupidanthus calyptratus, member this with most...
Detailed wood anatomical data for 32 species from all nine genera of the tribe Podalyrieae are presented, together with numerical analyses and mapping character states onto latest available molecular phylogeny. It was found that trees (Cadia, Calpurnia Virgilia) have vessels in small isolated groups, whilst fynbos shrubs (the remaining genera: Amphithalea, Cyclopia, Liparia, Podalyria, Stirtonanthus Xiphotheca) commonly show highly grouped narrow (frequently a dendritic pattern), helical...
Premise Despite intensive research, the pathways and driving forces behind evolution of derived woodiness on oceanic islands remain obscure. The genus Daucus comprises mostly herbs (therophytes, hemicryptophytes) with few rosette treelets (chamaephytes) endemic to various Macaronesian archipelagos, suggesting their independent evolution. To elucidate evolutionary woodiness, we examined phylogenetic relationships habit secondary xylem in related taxa. Methods Sixty taxa were surveyed for...

Abstract Keteleeria is a small genus of Pinaceae now mainly restricted to eastern Asia. Although this has been documented with wide distribution in the geologic record Europe, North America, and Asia, its history low‐latitude areas (including South China) remained obscure. In paper, fossil wood sp. described from Late Pleistocene (29–27 ka BP) Maoming Basin, China. This most ancient megafossil evidence within modern area genus. The records suggests that thermophyllous migrated into China by...
Abstract Main conclusion The monocot cambium is semi-storied, and its cells do not undergo rearrangement. a lateral meristem responsible for secondary growth in some monocotyledons of Asparagales. It an unusual meristem, homologous with the vascular cambia gymnosperms non-monocotyledonous angiosperms. Owing to limited information available on characteristics this aim study was survey structure order clarify similarities dissimilarities trees. Using serial sectioning analysis, we have studied...
Abstract Factors influencing diversification rates may be of intrinsic (e.g. morphological novelties) or extrinsic long-distance dispersal, availability ecological niches) nature. Growth habit influence because herbaceous plants often have shorter generation times and a more pronounced r reproductive strategy than their woody relatives. We examined life history evolution, wood anatomy biogeographical Apiaceae tribe Apieae in conjunction with rate analysis to explore which factors affected...
