The Sporobolinae share most of the same character trends as for the Zoysieae, i.e., spikelets with a single floret, spiciform inflorescences of numerous deciduous racemelets disposed along a central axis, lemmas usually rounded and rarely with apical awns, and glumes often modified and oddly shaped, but differ by having modified caryopses (pericarps free, reluctantly so in Spartina; a free pericarp that separates completely from the seed has been referred to as the "cistoid type" whereas the "follicoid type" has a free pericarp adjoining the seed; we do not know which subtype applies to Spartina, see Sendulsky & al., 1986;Yang & al., 2008), spikelets oriented abaxially along the axis (lemma is facing the rachis), lemmas that are similar in texture to the glumes, and paleas that are relatively long and about the same length as the lemma (Peterson & al., 2004(Peterson & al., , 2007. Zoysia species have a true caryopsis with fused pericarps, spikelets oriented adaxially along the axis (lemma facing away from the rachis), lemmas less firm than the glumes, and paleas relatively short or very reduced when compared with the lemma (Peterson & al., 2007).…”

The grass subtribe Sporobolinae contains six genera: Calamovilfa (5 spp. endemic to North America), Crypsis (10 spp. endemic to Asia and Africa), Psilolemma (1 sp. endemic to Africa), Spartina (17 spp. centered in North America), Sporobolus (186 spp. distributed worldwide), and Thellungia (1 sp. endemic to Australia). Most species in this subtribe have spikelets with a single floret, 1-veined (occasionally 3 or more) lemmas, a ciliate membrane or line of hairs for a ligule, and fruits with free pericarps (modified caryopses). Phylogenetic analyses were conducted on 177 species (281 samples), of which 145 species were in the Sporobolinae, using sequence data from four plastid regions (rpl32-trnL spacer, ndhA intron, rps16-trnK spacer, rps16 intron) and the nuclear ribosomal internal transcribed spacer regions (ITS) to infer evolutionary relationships and provide an evolutionary framework on which to revise the classification. The phylogenetic analysis provides weak to moderate support for a paraphyletic Sporobolus that includes Calamovilfa, Crypsis, Spartina, and Thellungia. In the combined plastid tree, Psilolemma jaegeri is sister to a trichotomy that includes an unsupported Urochondra-Zoysia clade (subtr. Zoysiinae), a strongly supported Sporobolus somalensis lineage, and a weakly supported Sporobolus s.l. lineage. In the ITS tree the Zoysiinae is sister to a highly supported Sporobolinae in which a Psilolemma jaegeri-Sporobolus somalensis clade is sister to the remaining species of Sporobolus s.l. Within Sporobolus s.l. the nuclear and plastid analyses identify the same 16 major clades of which 11 are strongly supported in the ITS tree and 12 are strongly supported in the combined plastid tree. The positions of three of these clades representing proposed sections Crypsis, Fimbriatae, and Triachyrum are discordant in the nuclear and plastid trees, indicating their origins may involve hybridization. Seven species fall outside the major clades in both trees, and the placement of ten species of Sporobolus are discordant in the nuclear and plastid trees. We propose incorporating Calamovilfa, Crypsis, Spartina, Thellungia, and Eragrostis megalosperma within Sporobolus, and make the requisite 35 new combinations or new names. The molecular results support the recognition of 11 sections and 11 subsections within Sporobolus s.l.; four sections are new:

“…Bamboos are an economically important group of plants, and their classification and evolution are important topics of study (Clark et al 1995, Clark 1997Sun et al 2006;Yang et al 2008). However, conventional classification, which is largely based on floral characteristics, is less useful in woody bamboos owing to their long flowering cycles that range from 20 to 120 years (Clayton and Renvoize 1986;Li 1997;Ramanayake et al 2007;Yang et al 2008).…”

The leaf waxes of 23 woody bamboo species of three subgenera, Dendrocalamus, Bambusa and Dendrocalamopsis, from the Xishuangbanna tropical rain forest in Southwest China were analyzed by gas chromatography and coupled gas chromatography-mass spectrometry. The waxes of the Dendrocalamus species are dominated by C 27 and C 29 n-alkanes and their average chain length (ACL) has an average of 28.3. In marked contrast to the Dendrocalamus species, the wax composition of the Bambusa species is characterized by a broad distribution of major n-alkanes from C 27 to C 35 , greater ACL values ([29) and an enhanced relative abundance ([30%) of n-alkanes with a carbon number greater than 30. Unlike the Dendrocalamus species and the Bambusa species, the Dendrocalamopsis species do not have a distinct n-alkane distribution; in some species the n-alkane distribution is comparable to that in the Bambusa species and in others to that in the Dendrocalamus species. The lipid data suggest that it might be reasonable to classify the controversial Dendrocalamopsis group as an independent genus separate from the Bambusa genus. On the basis of their smaller diversity of the dominant n-alkanes and their lower ACL values, the Dendrocalamus species might be more evolutionarily advanced than the Bambusa species, with the Dendrocalamopsis species being at an intermediate stage. The evolution and classification of the woody bamboos inferred from leaf wax n-alkanes are consistent with morphological investigations reported previously.

“…In the phylogenies of H.-Q. Yang et al (2008) and, species of Dendrocalamus form a clade within which members of Gigantochloa and Oxytenanthera are embedded. Unifying the three genera was suggested by Soderstrom and Ellis (1987), although Yang et al (2010) argue that this conclusion is still premature.…”

“…This subtribe was originally erected to include Neomicrocalamus, Racemobambos, and Vietnamosasa, which were thought to be distinguished from members of Bambusinae by having conventional spikelets. The analyses of Yang et al (2008) place Neomicrocalamus plus two species formerly in Racemobambos with Bonia in Bambusinae. Specifically, Racemobambos yunnanensis is sister to Melocalamus, whereas R. prainii is sister to Neomicrocalamus, with which it has been combined.…”
