Andropogoneae
editCoelorachis
editThe status of Coelorachis varied as of November 2024[update]. A 2015 classification of Poaceae treated the genus as a synonym of Mnesithea.[1] This placement was supported by Welker et al. in 2020, based on a molecular phylogenetic study,[2] and was used by the Germplasm Resources Information Network.[3] Alternatively, Plants of the World Online, following Veldkamp et al. in 2013,[4] treated the genus as a synonym of Rottboellia.[5]

Strumaria
edit- Grossi, Alberto (2014), "Strumaria in cultivation", The Plantsman, (New Series), 13 (4): 222–225
- Description
Species of Strumaria are deciduous bulbous plants. Their bulbs are generally small, around 7–35 mm (0.3–1.4 in) in diameter with a fibrous bulb tunic. Usually two leaves are produced, although there may be up to six. The flowers generally appear in the autumn with the arrival of the rains; the leaves may appear with, before or after the flowers. The inflorescence is 20–40 cm (8–16 in) tall, with an umbel of two to 30 flowers, that generally have long pedicels. Most species have white flowers, although they may also be pink or yellow. The six stamens are joined to the style, at least at the base. Strumaria is distinguished from other genera in the family Amaryllidaceae by the presence of a thickening at the base of the style, except in Strumaria spiralis, previously placed in its own genus Carpolyza. The seeds are reddish green when ripe, with a diameter of 2–5 mm (0.1–0.2 in). When dry, the fruiting heads detach from the scape and are rolled away by the wind, thus dispersing the seeds.

editHennig again
editConsider three features distributed among four groups like this:
Group | Feature 1 | Feature 2 | Feature 3 |
---|---|---|---|
A | yes | no | no |
B | no | no | no |
C | yes | yes | yes |
D | yes | yes | no |
The universe of discourse consists only of A, B, C and D and Features 1, 2 and 3.
Then in the Hennigian approach, we look for apomorphies.
- Feature 1 is a synapomorphy of A, C, D, i.e. A+C+D are a clade
- Feature 2 is a synapomorphy of C, D, i.e. C+D are a clade
- Feature 3 is an autapomorphy of C
Then the only possible cladogram (bar rotations) is:
−−− |
| ||||||||||||||||||
So far, so good. What about (sym)plesiomorphies? Since Feature 1 is a synapomorphy of A+C+D, it's a symplesiomorphy of any subset, i.e. A+C, A+D, C+D. C+D do form a clade but their shared possession of Feature 1 offers no evidence for this in the Hennigian approach because it's a symplesiomorphy with respect to A (in my terminology). [In other phylogenetic methods, e.g. parsimony, it would add support for this cladogram.] If Feature 3 is a radical innovation, and Feature 2 only a minor change, in traditional Linnean classification we could argue for putting A and D in one (paraphyletic) group and C in another. But there's no Hennigian evidence for this: all that A and D share is Feature 1, which is a symplesiomorphy (with respect to C). What about the absence of Feature 3? That's a (kind of) symplesiomorphy, in this case inherited by A, B and D from their common ancestor, but C has "lost" the absence. The absence of Feature 3 can define a paraphyletic group, but not a Hennigian clade, which must have a synapomorphy.
In the strict Hennigian approach, the only groups of real interest are monophylies; paraphylies and polyphylies are just different kinds of non-monophylies. In the same way, the only features of real interest are synapomorphies – those features which define a clade because they are shared by all members of the clade and are derived from the ancestor of the clade (although they may have been lost later). Symplesiomorphies are just features which aren't synapomorphies and hence characterize non-monophylies.
A synapomorphy necessarily involves at least one group outside the clade – an outgroup in modern phylogenetic studies – from which the "morphy" is "apo". That's what I mean by "with respect to". (For example, in my cladogram above, A is outside the clade C+D because it doesn't have the synapomorphy Feature 2. Feature 2 is a synapomorphy of C+D with respect to A – or indeed with respect to any other group.)
Can we describe Feature 1 as a synapomorphy of C+D? The simplest answer is "no". An "apo-morphy" must be "apo" something. In this case it's "apo" the absence of Feature 1. So the only group of which Feature 1 is a synapomorphy is A+C+D. Another answer, and here I think I may be departing from the Hennigian approach (although I find explanations of it unclear on this point) is that Feature 1 is a synapomorphy of C+D with respect to B. Feature 1 is a shared (i.e. syn) difference (i.e. apomorphy) of C and D from B. But it's not a shared difference of C and D from A, so it's not an "absolute" synapomorphy.
A symplesiomorphy necessarily involves at least one group within a clade whose sharing of the clade-defining feature (or possibly having lost it) is being ignored – that's what I mean by "with respect to". (For example, in my cladogram above, if we group A and D on the basis of sharing Feature 1, we're ignoring C which also has Feature 1. Feature 1 is symplesiomorphy of A and D with respect to C.)
