In northern habitats, this species grows throughout the summer at a broad range of elevations, where as in the southernmost habitats it is either restricted to the higher elevations or puts on most of its growth during the early growing season.
The mesophyll cells are densely packed and radiate outward from the bundle sheath; all mesophyll cells are intimately associated with the vascular bundle by compartmentalization.
The mesophyll cells are loosely packed and with air spaces (similar to Pooideae and other C3 grasses); however, all mesophyll cells are intimately associated with the vascular bundle by proliferation of the vascular strands, and thus mestome bundle sheath.

The grass subfamily Panicoideae includes over 3000 species, approximately 500 of them in the polymorphic and polyphyletic genus Panicum.
The Panicoideae are monophyletic, supporting all previous molecular and morphological studies.
The subfamily is divided into three strongly supported clades, representing groups with the same chromosome base number: the Andropogoneae (x=10), x=10 Paniceae and x=9 Paniceae; the first two may be sister taxa, but this result is not strongly supported.

The conversion from a bisexual to unisexual floral meristem in Zea mays is correlated with programmed cell death and the expression of tassleseed2 (ts2).
Preliminary results suggest that ts2 sequence is largely conserved within Panicoideae (nucleotide divergence 3.1-6.1%, amino acid divergence 1.7-6.5%) and Bambusoideae (nucleotide divergence 6.2%, amino acid divergence 4.7%), but less so within Ehrhartoideae (nucleotide divergence 17.1% amino acid divergence 16.5%), largely due to the Zizania sequence.
Nucleotide sequence divergence between Oryza and Bambusoideae (7.8-9.5%) and Panicoideae (7.8-9.5%) taxa, is less than the estimated divergence between Oryza and Zizania.

We are using sequences of phytochrome B, a low-copy nuclear gene, to reconstruct phylogenetic relationships within Poaceae subfamily Panicoideae.
Results corroborate relationships found by two earlier studies based on chloroplast markers (ndhF; combined sequences of the trnL intron and the trnL-trnF intergenic spacer regions).
All studies have demonstrated multiple origins of the C4 photosynthetic pathway within the Panicoideae, leading to the unexpected revelation that chromosome number is a better predictor of phylogenetic relationships than is photosynthetic pathway.

Orders Base Monocots: Acorus Alismatales Asparagales Dioscoreales Liliales Pandanales Family Petrosaviaceae Commelinids: Arecales Commelinales Poales Zingiberales Family Dasypogonaceae The Monocotyledons or monocots are an extremely important group of flowering plants, dominating great parts of the earth and with many economically important plants.
Subfamilies There are 7 subfamilies: Subfamily Arundinoideae Subfamily Bambusoideae Subfamily Centothecoideae Subfamily Chloridoideae Subfamily Panicoideae Subfamily Pooideae Subfamily Stipoideae The true grasses are monocotyledonous plants (Class Liliopsida) in the Family Poaceae, also known as Gramineae.
Genera Many; see list of Arecaceae genera Arecaceae (also known as Palmae), the Palm Family, is a family of flowering plants, belonging to the monocot order, Arecales.

There are now known to be 72 species of grasses that have the agamospermous type of apomixis and 11 additional species that reproduce, at least sometimes, by vivipary.
In the subfamily Panicoideae apomixis was found in 28 per cent of the species examined and all but one apomictic species formed 4-nucleate embryo sacs.
It is concluded that apomictic Panicoideae form 4-nucleate embryo sacs, and, conversely, that 4-nucleate embryo sacs are unreduced.

 Poaceae Phylogeny   (Site not responding. Last check: 2007-09-30)
Significant relationships that appear consistently in all analyses of all data sets and are strongly supported by the combined analysis include the following: Joinvilleaceae are sister to a monophyletic Poaceae; the earliest diverging lineages of the Poaceae are the Anomochlooideae, Pharoideae, and Puelioideae, respectively; and all remaining grasses form a clade.
The PACCAD Clade is monophyletic, containing Aristidoideae, Danthonioideae, Arundinoideae s.str., Chloridoideae s.l., Centothecoideae, Panicoideae, Eriachne, Micraira, and Gynerium.
Based on the phylogeny, a classification of 11 previously published subfamilies (Anomochlooideae, Pharoideae, Puelioideae, Bambusoideae, Ehrhartoideae, Pooideae, Aristidoideae, Arundinoideae, Chloridoideae, Centothecoideae,, and Panicoideae) and 1 new subfamily (Danthonioideae) is proposed.

We present a phylogeny of Poaceae subfamily Panicoideae based on analyses of three independent datasets, two chloroplast (ndhF, rpoC2) and one nuclear (phytochrome B).
Although Andropogoneae are exclusively C4-NADP-ME, C3 taxa are interspersed throughout the remainder of the Panicoideae and some are basal in each clade of the Paniceae.
Preliminary analyses suggest that a single origin with multiple reversals is slightly less parsimonious than multiple independent origins followed by a variable number of reversals.

 Grass Starch Grains   (Site not responding. Last check: 2007-09-30)
The nature of the grains has some value in grass systematics, especially at the subfamily level.
For example, while simple grains are found in many taxa in the Panicoideae, taxa of the Festucoideae and Chloridoideae are often characterized by compound grains.
Wheat (Triticum) has simple starch grains that are widely variable in size.
