The goals are (1) to test the monophyly of Subtribe Artemisiinae and the Artemisia-group; (2) determine the phylogenetic placements of the segregate and allied genera in relation to Artemisia s.s.; and (3) evaluate the patterns of diversification and test biogeographic hypotheses and evolutionary trends in capitular and floral morphology in the Artemisia-group [49,50].
The closest sister genera to Subtribe Artemisiinae are Nipponanthemum and Leucanthemella (Subtribe Leucantheminae).
An ITS phylogeny of Subtribe Leucantheminae [71] also excluded these two genera from that subtribe, which is otherwise Mediterranean in distribution, congruent with a chloroplast phylogeny based on ndhF for the entire tribe [64].

The subtribe Plectranthinae and Ociminae are both characterised by the 2-lipped calyx, with the corolla anterior lip long and strongly concave in the former, short and flat or slightly concave in the latter.
The genus was considered to be close to Orthosiphon in subtribe Ociminae by Ashby (1936), or close to Aeollanthus and Pycnostachys in subtribe Plectranthinae by Agnew (1974) and Codd (1985).
The posterior lip ranges from continuous on the tube, to slightly decurrent to strongly decurrent; the lateral teeth of anterior lip from obsolete, to ovate to oblong, or the lateral teeth are similar in shape and size to lower teeth; and the lower teeth of anterior lip range from free to long united.

Subtribe Galinsoginae comprises approximately 125 species of herbs and weak shrubs distributed mainly in the highlands of Mexico with a few species in similar habitats of Central America and the northern Andes.
The subtribe has recently been circumscribed to include mostly herbaceous sunflowers with white, trilobed ray corollas, prismatic cypselae and a dibasic chromosome number of x = 8, 9.
Results from comparative studies based on sequence data of the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA reveal two main clades that correspond to historical divisions in the subtribe based on chromosome number and cypsela pappus characteristics.

- Pollen morphology and phylogeny in Euphorbiaceae, subtribe Flueggeinae.
The affinities and delimitation of four closely related genera of Euphorbiaceae subtribe Flueggeinae-- Breynia, Glochidion, Phyllanthus, and Sauropus-- are examined by SEM observations (supplemented by LM) on pollen of 35 species, mostly belonging to the primarily paleotropical subgenera of Phyllanthus: Emblica, Eriococcus, and Phyllanthodendron.
The plesiomorphic condition in this clade within subtribe Flueggeinae appears to be that found in subgenus Emblica: prolate, 4-colporate grains with reticulate exine; pollen grains in subgenus Phyllanthodendron are 5-6-colporate, in subgenus Eriococcus pantoporate.

When the subtribe Oncidiinae is considered as a whole, the variation of chromosome numbers seems very similar to that of the genus Oncidium (Figure 6), with the numbers n = 21 and n = 28 prevailing, suggesting that the other genera have a common ancestor with Oncidium.
The main haploid numbers are n = 27 and 23 in the subtribe Eulophiinae, n = 21, 20, n = 28, 27 in the subtribe Cyrtopodiinae, n = 20 in a single species of Acriopsidinae, and n = 27 and n = 34 in Catasetinae.
In general the subtribe Eulophiinae is cytologically represented by Eulophia, which displays the second largest variation in chromosome numbers known in the phylad.

Subtribe Artemisiinae of Tribe Anthemideae (Asteraceae) is composed of 18 largely Asian genera that include the sagebrushes and mugworts.
The subtribe includes the large cosmopolitan, wind-pollinated genus Artemisia, as well as several smaller genera and Seriphidium, that altogether comprise the Artemisia-group.
We constructed a molecular phylogeny for the subtribe using the internal transcribed spacers (ITS) of nuclear ribosomal DNA analyzed with parsimony, likelihood, and Bayesian criteria.

The subtribe Bambusinae usually has fruit with a conspicuous appendage (persistent style) which is a growth of the pericarp at the tip of the ovary formed after fertilization.
At the subtribal and generic levels, Clayton and Renvoize (1986) recognized only 49 genera in three subtribes, i.e., Arundinariinae (20 genera), Bambusinae (25 genera) and Melocanniae (4 genera), while Soderstrom and Ellis (1987) accepted 59.

To understand more clearly the broader significance of such mechanisms in the evolution of closely related species, it is necessary that more putative cases of hybridization and rapid radiation are explored in complex species groups in a well-defined phylogenetic framework.
The majority of species in the subtribe are included in the complex genus Castilleja.
Taxonomic confusion in Castilleja stems from complex morphological variation often attributed to polyploidy and hybridization, and the difficulty in circumscribing taxa due to overlapping variation in nearly every character, which may be the result of a recent radiation of the genus.

 Crawford, Daniel J.*, Rebecca T. Kimball, and Mesfin Tadesse.
A molecular phylogenetic study of subtribe Coreopsidinae was conducted using ITS sequences from 18 genera traditionally placed in the subtribe.
Prior investigations of the subtribe have included grouping genera to reflect relationships and cladistic analyses of morphological characters; certain results of the present study are concordant with previous studies whereas in other instances sharply different relationships are portrayed.
The molecular phylogeny resolves a number of strongly supported lineages within Coreopsidinae, but there is not always clear resolution of relationships among the lineages.

 Aleocharina
The subtribe Aleocharina is comprised of about 10 genera and approximately 450 species.
The status of the subtribe and its included genera is very unstable because of uncertainties in the limits of the genus Aleochara and related genera and subgenera.
Thus, the characteristics of the subtribe Aleocharina are these same as those of the tribe Aleocharini.

The soybean is a papilionoid legume (family Fabaceae, subfamily Faboideae), and a member of the tribe Phaseoleae, subtribe Glycininae.
The subtribe to which soybean belongs consists of 16 genera, none of which, save for soybean (Glycine) and kudzu (Pueraria), are commonly known outside of botanical science.
The genus Glycine is unique within the subtribe on several morphological and chromosomal characters, and does not seem to bear an especially intimate relationship with any other genus in the subtribe (Lackey, 1977).

 Rhysodina
The Rhysodina are a medium sized subtribe of Rhysodini with one rather large and diverse genus (Kaveinga) and two very small additional ones.
Representatives of the subtribe occur in Australia, the Pacific Islands from New Zealand and New Caledonia west to Mindanao and Sulawesi, and also in the Palaearctic.
The subtribe is easily recognized by the enlargement of the median lobe of the head, which extends posteriorly to the neck region, completely separating the temporal lobes.

Their hypothesis that subtribe Pleurothallidinae has undergone a unilinear reduction in the number of pollinia was not supported by their study.
These studies represent preliminary phylogenetic research of the subtribe and the low sampling (28 genera and 58 taxa) may not reflect the evolutionary history of the group.
The established subtribal phylogenetic trends of reduction in number of pollinia and specialization of the perianth may be correlated with particular morphological trends, which are either reductionary or involve specializations directly related to the water relations of the epiphytic habit.

Tribe and subtribe names (where relevant and known) have now (July, 2003) been assigned to the genus-group names in the butterfly families Hesperiidae, Lycaenidae, Nymphalidae, Papilionidae, Pieridae and Riodinidae - following Lamas et al.
Where a subfamily is divided into tribes, but a genus-group name is unassigned to a tribe we have used the expression 'Tribe unassigned'; similarly where a tribe is divided into subtribes, but the genus-group name is unassigned to a subtribe we have used the expression 'Subtribe unassigned'.
For genus-group names included within a tribe or subtribe see the list of Tribes and Subtribes.
