Leaf morpho-anatomy of five sect. <em>Stachyobium</em> species from China were investigated using microscope and paraffin section to provide anatomic evidence for taxonomic significance. (1) Leaf size and apex of blade were varied among species and could be used for species delimitation. (2) Two shapes of ordinary epidermal cell were recognized, consisting of narrow-polygonal cell and broad-polygonal cell. The adaxial ordinary epidermal cells were conspicuously larger than the abaxial epidermal cell. The anticlinal wall of ordinary epidermal cells was straight-arched, with obvious thickenings. Peltate glandular trichomes occurred on both sides of leaf blade, with higher density on the abaxial surface. (3) Tetracytic stomata was observed only in <em>D. compactum</em>, while co-occurrence of tetracytic and anomocytic stomata was found in other four species. (4) Two types of outlines of leaf midrib were recognized, including flat type and carinate type. (5) The bicollateral vascular bundle was only observed in <em>D. strongylanthum</em>, but the amphivasal vascular bundle was commonly observed in the rest four species. (6) Two types of peltate trichome were firstly described anatomically, including a uni-celled stalk type and a bi-celled stalk type. Two types of crystals were present in idioblasts, including the spherical silica body in <em>D. sinominutiflorum</em>, and prismatic crystal in the rest four species. The monophyletic sect. <em>Stachyobium</em> was strongly supported by a comparative morpho-anatomy of leaf. Some morpho-anatomic features were selected and used for species discrimination and taxonomy of <em>Dendrobium</em>, including leaf size, leaf shape, apex of blade, the ordinary epidermal cell shape, stomatal density, leaf midrib outline, type of vascular bundle, anatomic type of peltate trichome, and crystals.

Previous studies strongly suggest that the simple pollen-cone structure of some Taxaceae s.l. is most likely derived from a compound structure and each microsporangiophore represents a lateral, however markedly reduced flower. To test if a similar evolutionary pathway remembering the pseudathium concept sensu Wettstein applies also for Pinaceae, normal shaped and abnormal pollen-cones of <em>Pinus bungeana</em> (Pinaceae) are investigated with SEM and paraffin microtome technique. <em>Pinus sylvestris</em>, which is the type species of the genus, is used as another example. The early development of bisporangiate microsporangiophores starts with two distinct primordia. They fuse in basal parts and form a common stalk. The distal parts remain free and each develops a stalk, a distinct phyllom-like scutellum and one abaxial microsporangium. In some bisporangiate microsporangiophores two monosporangiate microsporangiophores are inserted laterally at the common stalk, which forms a distinct terminal apex. Other microsporangiophores bear a subunit in form of a second, however, aborted microsporangiophore in a lateral position at the base of the common stalk. It is suggested that the bisporangiate microsporangiophore is not a staminate leaf in the sense of a microsporophyll, but a dorsiventral synangium consisting at least of two fused microsporangiophores. In this case each microsporangiophore corresponds to a markedly reduced cone (= flower) which however has lost its pherophyll (= subtending leaf). Similar as shown for <em>Torreya</em> the simple pollen-cone structure in Pinaceae is thus derived from a pseudanthial (= compound) origin.</p></div>","PeriodicalId":55156,"journal":{"name":"Flora","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0367253024001105/pdfft?md5=47e56f82d763ef410e6ea9a5f4915ab1&pid=1-s2.0-S0367253024001105-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141484896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some factors of the abiotic environment may also contribute to the maintenance of staggered flowering. Flowering (a)synchrony among conspecifics is recognized as a trait with selective value. However, little research has addressed phenotypic selection for (a)synchrony with other plant species. Here, I experimentaly examined the flowering phenology of two sympatric congeneric species (<em>Cnidoscolus aconitifolius</em> &amp; <em>C. souzae</em>) that share pollinators and measured phenotypic selection on this trait. Preliminary field observation suggests that these species exhibit staggered flowering, so my main goal was to assess phenotypic selection on flowering (a)synchrony between the two study species (interspecific synchrony). I predicted that the plants that present greater interspecific synchrony would be selected against and would thus contribute to the maintenance of staggered flowering. However, the patterns of phenotypic selection found were counterintuitive: individuals of <em>C. souzae</em> with greater intraspecific synchrony were selected against, while those with greater interspecific synchrony with <em>C. aconitifolius</em> were favoured by phenotypic selection. I also found the opposite pattern of flower production response to temperature in this system, implying that the abiotic environment could partly explain the occurrence of staggered flowering. Since the phenotypic selection found in this study may select against the observed staggered flowering, reciprocal phenotypic selection between co-occurring plants cannot be invoked as a mechanism underlying staggered flowering phenology in these two <em>Cnidoscolus</em> species.</p></div>","PeriodicalId":55156,"journal":{"name":"Flora","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141412155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, only a few species have been anatomically described, and a comprehensive characterization of the genus for comparative purposes is still needed. Our study aimed to examine the main vegetative morphoanatomical characters of the root, stem, and leaves, and analyze their evolution based on the phylogeny of the genus. We analysed root, stem, and leaf samples from 57 species using light and scanning electron microscopy. We selected 35 characters and mapped them onto the molecular phylogeny. <em>Pabstiella</em> exhibits homogeneous leaf anatomy, with aquiferous tissue on both sides and chlorophyllous parenchyma in the middle, aligned with vascular bundles. The ramicaul anatomy displays a simple epidermis with primary or secondary walls, a simple to stratified hypodermis, a parenchymatous or aerenchymatous cortex, and a sheath of sclerenchyma surrounding the vascular bundles. The roots endovelamen cells are larger than those in the epivelamen, reticulated tilosomes of varying morphotypes, and giant cells in the cortex. Despite the common occurrence of homoplasy among vegetative traits, particularly in the leaves, our analyses revealed several synapomorphies for the genus. These include the presence of giant cells in the root cortex, endovelamen cells larger than those of the epivelamen, a specific distribution pattern of tilosomes, and 2–3 layers of aquifer tissue on the adaxial face of the leaf. Additionally, for the <em>Pabstiella</em> section, a lignified stem epidermis wall is a synapomorphic character state.

We investigated the adaptive convergence of the family as well as the fragile balance between fine-scale variation in adaptive traits and general convergence towards stress-tolerance and adaptation to aridity, using thorough field surveys and trait-based ecological approaches. Data was collected between 2020 and 2022 using the quadrat approach encompassed across 60 sites and five habitat types. Multivariate statistical methodologies were applied to analyze plant traits and soil variables. The tribes Cichorieae, Cardueae, and Heliantheae emerged as dominant contributors to the flora, illustrating their adaptability to varied ecological conditions. Microphyll emerged as the dominant leaf type, and therophytes prevailed as the most abundant life form. Urban habitats exhibited heightened sensitivity to Asteraceae species, as reflected in diversity indices. Canonical Correspondence Analysis demonstrated the significant influence of soil moisture, pH, phosphorus, and soil saturation on species distribution, with indicator species analysis highlighting habitat-specific plant-environment relationships. The study further classified species into adaptive strategies using CSR (competitive strategy-stress tolerant strategy-ruderal strategy) categorization. While some species exhibited pronounced R or S strategies, a majority demonstrated mixed strategies, such as R/CR, R/CSR, CS/CSR, emphasizing the versatility of adaptation strategies within the Asteraceae family. The findings underscore the intricate interplay between environmental variables and Asteraceae phylogenetic and functional diversity, highlighting the significance of soil properties in influencing plant distribution in semi-arid ecosystems.

The core evidence supporting these hypotheses is the frequency of terrestrial plants that accidentally grow as epiphytes (i.e., accidental epiphytes), because these plants should be abundant in the habitats that promote the colonization of the canopy by the terrestrial plants (i.e., the early state of epiphyte evolution). In a landscape with both environments (humid and umbrophilous vs. open and infertile), we tested the affinity of the flora to the epiphytic habitat and the association of the accidental epiphytes with each environment. We found 71 plant species. Forty-one percent were terrestrial; among the rest, 39 %, 3 %, and 17 % were accidental, facultative (growing equally as terrestrial or arboreal), and true epiphytes (preferentially living as arboreal), respectively. Discounting plants that exclusively grow terrestrially in the sample, in this landscape, a large proportion of the species living in tree crowns are accidental epiphytes (28), and 16 species belong to Asteranae and Rosanae, superorders where epiphytism is infrequent. Nine accidental epiphytes were associated with the open environment and none with the forest, supporting only the Tietze-Pittendrigh hypothesis.
