GENUS INDEX

GENUS CODE: DICHA2
GENUS SCIENTIFIC: Dichanthelium
GENUS AUTHORITY: (Hitchc. & Chase) Gould
GENUS COMMON: Rosette grass
GENUS SUMMARY: (by Richard J. LeBlond)
GENUS IDENTIFICATION: Identification notes: Dichanthelium has often been treated as subgenus Dichanthelium of Panicum. It is most readily (though not consistently) separated from Panicum by the following combination of features: plants producing over-wintering rosettes of leaves often shorter and broader than the culm leaves; plants producing simple culms with terminal panicles in spring, the culms branching and producing panicles only on branches in the summer and autumn. Perhaps the most complex and confusing genus in our region, Dichanthelium requires careful collection and close observation of several characters to determine to which taxon a specimen belongs, or at least to which taxa it seems most closely aligned. A taxon that is distinct in one part of its range may be indistinguishable from another taxon elsewhere. This is particularly true of Coastal Plain species adapted to natural (and now human) disturbances. Although hybridization is frequently suspected in Dichanthelium, documentation of natural hybrids is rare.
GENUS REFERENCES: Gould and Clark (1978)=Z; Freckmann (1981)=Y; Lelong (1984)=X; LeBlond (2001)=Q; Weakley et al. (2011)=V; Davidse and Polh (1992); Hansen & Wunderlin (1988); Hitchcock & Chase (1910); Freckmann & Lelong (2002). The treatment of Dichanthelium sect. Lanuginosa (=D. acuminatum group) is based closely on Y. The contributor must take responsibility for the treatment of sect. Angustifolia (including D. hirstii), sections Dichotoma and Ensifolia (the D. dichotomum group), and for sect. Lancearia. Other treatments are based largely on Z.

FAMILY INDEX

FAMILY CODE: POACEA
FAMILY SCIENTIFIC: Poaceae
FAMILY AUTHORITY: (R. Brown) Barnhart 1895 or GRAMINEAE A.L. de Jussieu 1789
FAMILY COMMON: Grass Family
FAMILY SUMMARY: A family of about 771 genera and 12,074 species, herbs (and some shrubs and trees), cosmopolitan. Tribal classification largely follows FNA (2003a, 2007a), with some changes based on subsequent research, as for instance in the Chloridoideae (Peterson, Romaschenko, & Johnson 2010a).

SCIENTIFIC NAME: Dichanthelium scoparium
COMMON NAME: Velvet Witchgrass
SYNONYMY: [= FNA, K, Pa, Va, Z; = Panicum scoparium Lamarck - C, F, G, GW, HC, RAB, S]
PHENOLOGY: May-Oct.
HABITAT: Moist sandy soil of woodland openings and ditches.
COMMENTS: MA and MI south to FL and TX, also in Mexico and West Indies. The dense, velvety pubescence of the internodes, sheaths, and blades of this taxon, combined with the viscid band below the nodes, are diagnostic. See note under D. acuminatum var. fasciculatum regarding Panicum glutinoscabrum.
