Banksia subser. Leptophyllae
subseries of plants
Banksia subser. Leptophyllae is a
valid botanic name for a subseries of Banksia. It was published by Kevin Thiele in 1996, but discarded by Alex George in 1999.
Cladistics
The name came about after a cladistic analysis of Banksia by Thiele and Pauline Ladiges yielded a phylogeny somewhat at odds with the accepted taxonomic arrangement, prompting them to publish a revised arrangement. Their cladogram contained a clade that corresponded closely to George's B. ser. Abietinae. This clade resolved into four subclades, for which Thiele published four corresponding subseries. B. subser. Leptophyllae was based upon the fourth subclade:
Taxonomy
B. subser. Leptophyllae was formally defined as containing those taxa with "indurated and spinescent common bracts on the infructescence axes, and densely arachnose seedling stems." The epithet Leptophyllae is taken from the specific epithet of the type species, B. leptophylla (slender-leaved banksia), from the Greek leptos ("fine, slender") and phyllon (leaf).

Why this record matters
“Banksia subser. Leptophyllae” is worth following because a concise public description often conceals a longer documentary argument. Here, Banksia, subser and Leptophyllae provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Feb 12, 2026. The linked authority identifier is Q4856742. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1996 and 1999.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
