Abstract:
... Sebaea solaris (Gentianaceae) is here described as a new species from the Overberg region, Western Cape, South Africa. This new species is at first glance very distinct from all others in the genus mainly due to its relative large yellow flowers of c. 2.5 cm diameter with oblanceolate to obdeltoid erose corolla lobes. The petal ornamentation with several orange lines indicating the flower centre ( ...

Abstract:
... Hoya tengchongensis, a new species of Apocynaceae, subfamily Asclepiadoideae from Yunnan, China, is described and illustrated. The new species is morphologically similar to Hoya serpens in its creeping habit, bearing small and suborbicular leaves, and adaxially tomentose corolla. However, H. tengchongensis differs from H. serpens in corolla size (ca 7 mm versus ca 12 mm in diam) and corona morphol ...

Abstract:
... Two new species of the orchid genus Quekettia are described. Colombian Quekettia aureliae is distinguished from similar Q. microscopica by the pandurate lip with a pair of small, flap‐like calli in the isthmus between hypo‐ and epichile, and deeply emarginated epichile apex. Quekettia senghasiana found in Guyana resembles Q. papillosa but it is characterized by the free lateral sepals, oblanceolat ...

Abstract:
... Fundamental physics of laminar coflow diffusion flames was numerically studied under bulk flow perturbations. First the numerical method was verified by literature analytical models of linearized diffusion flames. Then it was extended to predict nonlinear characteristics of the full diffusion flame, as well as linearized flame dynamics. In full-precision model without axial diffusion, two petals a ...

Abstract:
... In Solanaceae, a group dominated by actinomorphic‐flowered species, floral zygomorphy is frequently observed among the early‐branching clades. Morphological studies indicated that a zygomorphic androecium is much more common than a zygomorphic corolla in the family. Ontogenic studies suggested the evolution of floral zygomorphy in these two whorls is independent. Here, we have examined the evoluti ...

Abstract:
... Some plant species possess petal hairs, the defensive functions of which remain untested. I hypothesized that the petal hairs of an emergent plant species, Menyanthes trifoliata (Menyanthaceae), have a function in deterring nectar-thieving ants (Lasius japonicus). Lasius japonicus individuals were observed to stop moving forward after touching hairs and had difficulty in maintaining their balance ...

Abstract:
... Some plants rapidly close their leaves in response to mechanical stimulation, but no case is known in which mechanical stimulation causes rapid petal closure. In this study, we found that Drosera tokaiensis closes petals within 2–10 min after experimental stimulation of the calyx, closed flowers or scapes with a pair of tweezers. Although petal closure was induced more rapidly by touching a positi ...

Interestingly, the petals of flowering plants display unique hierarchical structures, in which surface relief gratings (SRGs) are conformably coated on a curved surface with a large radius of curvature (hereafter referred to as wavy surface). However, systematic studies on the interplay between the diffractive modes and the wavy surface have not yet been reported, due to the absence of determinist ...

Abstract:
... BACKGROUND: Polyploidy has played a major role in angiosperm evolution. Previous studies have examined polyploid phenotypes in comparison to their extant progenitors, but not in context of predicted progenitor phenotypes at allopolyploid origin. In addition, differences in the trends of polyploid versus diploid evolution have not been investigated. We use ancestral character-state reconstructions ...

Abstract:
... Detarioideae is well known for its high diversity of floral traits, including flower symmetry, number of organs, and petal size and morphology. This diversity has been characterized and studied at higher taxonomic levels, but limited analyses have been performed among closely related genera with contrasting floral traits due to the lack of fully resolved phylogenetic relationships. Here, we used f ...

Ongoing debate about specialisation vs generalisation in plant–pollinators interactions highlights the reliability of pollination syndrome traits as predictors of the primary pollinator of a species. The South African Watsonia knysnana (Iridaceae) is a case in point as its tubular corolla is consistent with ornithopilous floral traits to attract sunbirds (specialist nectarivore passerines) but the ...

However, these concepts are rarely investigated on different resources within an individual plant, such as flowers and leaves, even though this can be informative on how each plant individual allocates differ ...
