Drought-tolerant perennials are intensively sought-after plants for decorative purposes. Perennial ferns cold-hardy cultivars that great shady to partially shaded areas of the garden, but their response drought stress is unknown. In this study, we examined how reduced watering altered growth Athyrium niponicum ‘Red Beauty’, Cyrtomium fortunei ‘Clivicola’, Dryopteris atrata, erythrosora, Dryoper...

Risk analysis plays a crucial role in regulating and managing alien invasive species but can be time-consuming costly. Alternatively, combining invasion impact history with distribution models offers cost-effective time-efficient approach to assess risk identify for which comprehensive should take precedence. We conducted such an assessment six traded fern species, determining their countries w...

Dryopteris blanfordii (C.Hope) C.Chr. is a member of the Dryopteridaceae, growing in high altitude Picea or Abies forests (2900-3500 m) in China and India. Phylogenetic relationships between D. blanfordii subsp. nigrosquamosa and closely related species of Dryopteris were investigated using a combined analysis of multiple molecular data sets (the protein-coding region of rbcL and matK genes and...

PREMISE OF THE STUDY Our goal was to infer the phylogenetic relationships and historical biogeography of the genus Dryopteris with a focus on taxa in sub-Saharan Africa and neighboring islands. In general, little is known about the relationships between African fern species and their congeners in other geographic regions, and our aim was to determine whether the sub-Saharan African species of D...

PRYER, K. M., and D. M. BRITTON. 1983. Spore studies in the genus Gymnocarpiurn. Can. J. Bot. 61: 377-388. Scanning electron microscopy was used to examine the variation in perispore characters within and between six currently recognized taxa of the genus Gyrnnocarpiurn Newm. in North America. Representative scanning electron micrographs are presented and depict the perispore features observed....
