Talk:Asplenium × ebenoides

Additional resources

This looks like a great start. I've been digging for some more resources. One important point is that relatively recently, Keener & Davenport, in the Journal of the Botanical Research Institute of Texas, separated the fertile, allotetraploid specimens found in Hale Co., AL from A. ebenoides as Asplenium tutwilerae. They cite some potentially useful literature on both species. I also found this account of its discovery in the Proceedings of the Royal Horticultural Society, as well as some other contemporary material that bears on the matter. I also found a link to the type specimen.

Some of the potentially useful references, which I'll put here temporarily:

• Murrill, W. Alphonso (1897), "Asplenium ebenoides in Virginia", Fern Bulletin, 5 (1): 1–3
• Small, John Kunkel (1935), Ferns of the Vicinity of New York, Lancaster, PA: The Science Press

  p. 59. Small asserts that both A. ebenoides and A. pinnatifidum "sometimes" propagate vegetatively (by buds at the tip).

• Davenport, George Edward (1878), "Asplenium ebenoides", Bulletin of the Torrey Botanical Club, 6 (37): 200 {{citation}}: Unknown parameter |month= ignored (help)

  Proliferous buds in culture.

Tasks

• We need a separate article on A. tutwilerae to describe the fertile tetraploids.
• Further description: rhizomes, sori, etc. Describing the cutting of the blade in an accurate manner comprehensible to the layman will be a challenge.
  • Comparison with most similar species and how to distinguish them. (A. tutwilerae, A. pinnatifidum?) Review some of the literature when the identity of A. ebenoides was being debated to see what characteristics to emphasize. Note also the description of which characteristics were viewed as typical of Camptosorus vs. Asplenium.
• Discovery of the Havana Glen population (A. tutwilerae) and the impact on the debate over whether this was or wasn't a hybrid, plus Slosson's experiments and Wagner & Whitmire's production of the allotetraploid.
  • n.b. Slosson's experiments weren't regarded as completely conclusive--there was still published skepticism post-1902.
• Consult various sources to accurately describe typical habitat/substrate requirements.
• Cultivation information.
