Lignotuber in Banksia serrata
There is doubt about the presence of a lignotuber. I do not see a reference to lignotuber in the cited articles. On the other hand, Mibus and Sedgley in "Early Lignotuber Formation in Banksia–Investigations into the Anatomy of the Cotyledonary Node of Two Banksia (Proteaceae) Species" note (page 577) "Whilst B. menziesii is clearly lignotuberous... with concealed lignotuber buds, confusion exists in the literature as to whether B. serrata is lignotuberous. B. serrata is characteristically arborescent, with a single stem. .... In his taxonomic survey of quantitative characters, Thiele (1993) was uncertain about the presence or absence of lignotubers in seedlings of B. serrata. George (1987)does not describe B. serrata as lignotuberous, stating that this species is fire tolerant, sprouting from epicormic shoots.  (Whilst Wikipedia is not about primary sources, I have seen the swelling at the base of this species but I have never seen an example of B. serrata recovering from fire from sprouting from this swelling.) I suspect a Wikipedia editor has assumed the swelling is a lignotuber. Gderrin (talk) 23:59, 10 January 2015 (UTC)


 * Right, the issue is what is and is not called a lignotuber and how it looks. Certainly alot of the typical lignotuberous species (robur, spinulosa and oblongifolia) have little buds all around the base of the stem which sprout if the plant is burnt or hard-pruned. Serrata (which is quite unrelated) doesn't. It has a thick trunk with different bark and lacks the buds as such, yet it does respond to fire by resprouting. In fact all species resprout by something on the outside as the wooden inside of any woody plant is by definition dead. I have George's monograph - will see what it says as it goes into more detail than anything else. Cas Liber (talk · contribs) 02:08, 11 January 2015 (UTC)


 * George's 1981 monograph dodges the question and just says it is fire tolerant. Taylor/Hopper Banksia Atlas noted epicormic and ground reshooting after bushfire and stated it is at least some of the time lignotuberous. More: Cas Liber (talk · contribs) 02:15, 11 January 2015 (UTC)


 * Right, this paper also says can be lignotuberous. This series of papers is a goldmine of info for all flora in Sydney basin. Cas Liber (talk · contribs) 02:19, 11 January 2015 (UTC)
 * Interesting indeed. Perhaps we can just leave it as "there is doubt"? Gderrin (talk) 01:35, 12 January 2015 (UTC)
 * We have to reflect what the sources say (like peer-reviewed hopscotch really :)) - Feel free to add that Thiele was uncertain (that ref is all over the place so you can cut and paste). The Benson paper has some links to some papers that look at this in some detail (Bradstock?) - I will try to chase up some fulltexts. Cas Liber (talk · contribs) 03:28, 12 January 2015 (UTC)


 * Aw! Can't we just saw a few off at ground level and see what happens? No? Pity. Still, the debate is interesting. Gderrin (talk) 07:24, 12 January 2015 (UTC)

Towards GA/FA-hood
Okay,, am buffing this for that so it can be mainpaged sometime Cas Liber (talk · contribs) 12:00, 3 June 2017 (UTC)
 * Made some changes, mainly to sentence structure. Also added a couple of new references. One of my favourites spp. (although none near here.) - GA or FA soon I hope. Gderrin (talk) 05:27, 5 June 2017 (UTC)


 * Need to look this up later. Cas Liber (talk · contribs) 09:58, 4 June 2017 (UTC)
