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...

Revwattsia fragilis (Watts) D.L. Jones (Dryopteridaceae), originally described as a Polystichum Roth by the pioneer Australian botanist Reverend W.W. Watts in 1914, is a rare epiphytic fern endemic to northeastern Queensland, Australia. Known from only a few populations, it is restricted to tropical rainforests in the Atherton Tablelands. We used the cpDNA markers psbA-trnH, rbcL, rbcL-accD, rp...

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....

Experimental studies with Bracken and Dryopteris ferns @ 25% concentrate ration mixture were conducted in rabbits. Fern fed rabbits showed progressive anaemia, leukopaenia, lymphopaenia and relative heterophilia. Significant elevations in serum enzymes like serum glutamate oxaloactate transminase (SGOT), serum glutamate pyruvate transminase (SGPT), alkaline phosphatase (ALP), urea and creatinin...

In our early experiments, the chloroform extract of D. crassirhizoma was demonstrated to contain the highest concentrations of total phloroglucinols among several extract fractions and possessed the most effective nematicidal activity. This study aimed to ascertain the ultrastructural changes in M. incognita after treatment with a D. crassirhizoma chloroform extract at 1 mg·mL⁻¹ for 24 h. It wa...

One new sesquiterpene and six known compounds were isolated from Dryopteris fragrans (L.) Schot. They were identified as 3-O-β-D-glucopyranosylalbicanol- 11-O-β-D-glucopyranoside (1), dihydroconiferylalcohol (2), (E)-3-(4-hydroxyphenyl)acrylic acid (3), esculetin (4), 5,7-dihydroxy-2-hydroxymethylchromone (5), eriodictyol (6) and isoorientin (7) by UV, MS, 1D-NMR and 2D-NMR spectroscopy. The an...

UNLABELLED PREMISE OF THE STUDY Discovering missing ancestors is essential to understanding the evolutionary history of biodiversity on Earth. Evidence from extinct species can provide links for reconstructing intricate patterns of reticulate relationships among extant descendents. When fossils are unavailable and other evidence yields competing hypotheses to explain species ancestry, data f...
