The Tree Fern Highland Lace is a Cultivar of Sphaeropteris cooperi

open access: yesAmerican Fern Journal, 2012
Abstract The tree fern Highland Lace had an unusual introduction into cultivation almost thirty years ago in Eastern Australia and was initially identified as Sphaeropteris tomentosissima (Copel.) R.M.Tryon. Since then, it has been introduced to Europe and the US, and it remains a popular tree fern found in both public and private collections.

Mortoniodendron (Tiliaceae) and Sphaeropteris/Trichipteris (Cyatheaceae) in Cenozoic Deposits of the Gulf-Caribbean Region

open access: yesAnnals of the Missouri Botanical Garden, 1979
Two previously unidentified palynomorphs are common in Upper Tertiary deposits in the southern Gulf-Caribbean region. One is now identified as pollen of Mortoniodendron (Tiliaceae; Upper Miocene of Veracruz, Mexico, Middle Miocene of Panama, Pleistocene of Panama). The other represents spores of Sphaeropteris/Trichipteris (Cyatheaceae; Upper Miocene of

SPORE MORPHOLOGY IN THE CYATHEACEAE. II. THE GENERA LOPHOSORIA, METAXYA, SPHAEROPTERIS, ALSOPHILA, AND NEPHELEA

American Journal of Botany, 1976
Scanning electron microscopy and transmitted light microscopy are used in a palynological study of Lophosoria, Metaxya, Sphaeropteris, Alsophila, and Nephelea of the tree fern family Cyatheaceae. The monotypic American genera Lophosoria and Metaxya each have a unique spore morphology which reinforces the taxonomic distinctness of these genera as ...

Genetic structure and phylogeography of a relict tree fern, Sphaeropteris brunoniana (Cyatheaceae) from China and Laos inferred from cpDNA sequence variations: Implications for conservation

Journal of Systematics and Evolution, 2011
In this study, we analyzed the genetic structure and phylogeography of Sphaeropteris brunoniana from China and Laos. Combining cpDNA trnL-trnF and atpB-rbcL sequence variations, five haplotypes were identified from the 10 investigated populations. Moderate haplotype diversity (h = 0.66580) and low nucleotide diversity (pi = 0.23 x 10(-3)) were detected.

Effects of cyanide, salicylhydroxamic acid, and temperature on respiration and germination of spores of the fern Sphaeropteris cooperi

Physiologia Plantarum, 1982
During the first 96 h of culture, germinating spores of the fern Sphaeropteris cooperi (F. v. Muell.) Tryon showed a gradual rise in respiratory activity to a maximum of about 6.5 μl 02 h−1 mg−1 dry wt. This was followed by a transitory decline in rate, concluded by a second respiratory rise preceding the emergence of the rhizoid after 192 h of culture.
