INVITED ARTICLE

Life-history monographs of Japanese plants 14: Cardamine leucantha (Tausch) O. E. Schulz (Brassicaceae)

  • Pages: 542-553
  • First Published: 14 July 2021
Description unavailable

The life-history characteristics including reproduction, demography, and population structures of Cardamine leucantha are described. This plant is an herbaceous perennial with a pseudo-annual life cycle. This species performs both of sexual reproduction via seeds and clonal growth by stoloniferous rhizomes, contributing population structures.

Modular growth and functional heterophylly of the phreatophyte Ziziphus lotus: A trait-based study

  • Pages: 554-566
  • First Published: 01 June 2021
Description unavailable

Through a trait-based approach, we identified the modular growth pattern and morpho-functionally distinct leaves (i.e., heterophylly) in the phreatophytic shrub Ziziphus lotus (Rhamnaceae), which promoted a functional differentiation between vegetative and reproductive structures. Both characteristics might contribute to prioritizing the investment of resources of this species, either for growth or reproduction, and could improve the efficiency in uptake and conservation of resources in drylands.

Decorative sterile flowers in nine Japanese species of Viburnum (Adoxaceae) and their influence on pollinator visits

  • Pages: 567-577
  • First Published: 06 July 2021
Description unavailable

Sterile flowers occur in a few species of Viburnum (Adoxaceae) and have been long hypothesized to increase the pollinator-attracting functions of their inflorescences. Our results support this hypothesis and hint that species without sterile flowers might have adapted other pollinator-attracting mechanisms, such as a high flowering synchrony within a single inflorescence.

Interspecific variation in clonality in temperate lianas revealed by genetic analysis: Do clonal proliferation processes differ among lianas?

  • Pages: 578-588
  • First Published: 01 August 2021
Description unavailable

Lianas are characterized by extensive clonal reproduction on the forest floor, which is important for their establishment and growth. This study evaluated the relative contribution of clonal reproduction at the on-tree and on-floor stages in four liana species in an old-growth temperate forest in central Japan. The results indicated that the clonal proliferation processes differ greatly among lianas and the clonal growth in lianas plays a contrasting role in their life-history strategy.

NOTES AND COMMENTS

Confirmation of clonal reproduction of Fagus crenata Blume from Sado Island, Niigata Prefecture

  • Pages: 589-595
  • First Published: 12 May 2021
Description unavailable

We aimed to confirm using nuclear microsatellite markers whether clonal growth occurs in the Japanese endemic species Fagus crenata by investigating the origin of multi-stemmed clumps found within a high-elevation dwarf beech forest on Sado Island, Niigata Prefecture. We found that all stems collected from three separate clumps belonged to the same clump-specific multi-locus genotypes forming clones up to 3–4 m in diameter. The species capacity for clonal growth is likely to underlie its ability to persist at high-elevation exposed sites at the limits of its ecological range.

Reciprocal crosses between Magnolia stellata and Magnolia kobus do not show significant reproductive barriers in seed formation

  • Pages: 596-601
  • First Published: 17 June 2021
Description unavailable

In the range of Magnolia stellata, a native rare subtree species, Magnolia kobus, an invasive planted/escaped tree species, can also be found. In order to examine possible natural hybridization between the two species, a reciprocal cross-pollination experiment was conducted. The results suggest that there are no reproductive barriers between the two species and planted/escaped M. kobus near the natural habitat of M. stellata presents a threat through hybridization.
