Abstract:
... Many geometries of plant organs can be described by the Gielis equation, a polar coordinate equation extended from the superellipse equation, r=acosm4ϕn2+1ksinm4ϕn3−1/n1. Here, r is the polar radius corresponding to the polar angle ϕ; m is a positive integer that determines the number of angles of the Gielis curve when ϕ ∈ [0 to 2π); and the rest of the symbols are parameters to be estimated. The ...

Abstract:
... Based on the complete chloroplast genome, morphology, and karyotype evidence, we identified a new nothospecies, Lycoris × jinzheniae S.Y. Zhang, P.C. Zhang & J.W. Shao, in eastern China. This new nothospecies has been inappropriately named Lycoris × albiflora in the previous literature for more than 30 years. However, the new nothospecies resulted from the hybridization of L. sprengeri and L. chin ...

Abstract:

Flower size is one of the most important showy traits in determining pollinator attraction, and a central factor determining the quality of floricultural products. Whereas the adverse effects of elevated temperatures on showy traits have been described in detail, it ...

We examined the evolution of diverse floral morphologies in a species‐rich tropical radiation of Rhododendron. We used restriction‐site associated DNA sequencing on 114 taxa from Rhododendron sect. Schistanthe to reconstruct phylogenetic ...
