Family Compositae

The largest family of flowering plants , the Compositae (Asteraceae), comprising about 1,100 genera and more than 20,000 species and characterized by many small flowers arranged in a head looking like a single flower and subtended by an involucre of bracts. A head may consist of both ray flowers and disk flowers, as in the sunflower, of disk flowers only, as in the burdock, or of ray flowers only, as in the dandelion.

Genus Solidago

Perennials , 5100(200) cm; woody caudices or rhizomes. Stems decumbent to ascending or erect , sometimes branched distally, glabrous or strigose , strigillose , hispid , or short-villous. Leaves basal (persistent or not by flowering) and cauline; petiolate (proximal ) or sessile (proximal and distal, latter sometimes subpetiolate) ; proximal blades sometimes 3-nerved, ovate-oblanceolate, margins often serrate, faces glabrous or densely hairy ; distal sometimes 3-nerved, glabrous or sparsely to densely scabrous , strigillose, or villous , sometimes stipitate-glandular , sometimes resinous . Heads usually radiate , sometimes discoid , (1) 21500+ in racemiform (club-shaped or pyramidal ), paniculiform or corymbo-paniculiform, sometimes secund arrays. Involucres campanulate to cylindric (often spreading upon drying), 312 × 1.710 mm. Phyllaries 1035 in 35 series, midnerves usually ± swollen and translucent , sometimes plus 25 secondary nerves (striate , flat), linear-lanceolate to oblong or ovate , unequal to rarely subequal , margins scarious , (apices rounded to acute or attenuate), faces glabrous or sparsely pilose or puberulent , sometimes minutely stipitate-glandular, sometimes resinous. Receptacles slightly convex , pitted , epaleate . Ray florets (0) 215(24), pistillate , fertile ; corollas yellow, rarely white (usually glabrous). Disc florets 235(60), bisexual , fertile; corollas yellow, ± ampliate , tubes shorter than throats (usually glabrous), lobes 5, erect to spreading, triangular to narrowly lanceolate; style-branch appendages broadly to narrowly triangular (lengths 0.71 times stigmatic lines ). Cypselae narrowly obconic to cylindric, sometimes somewhat compressed , ribs usually 810 (either darker and sometimes translucent or lighter than bodies), glabrous or moderately strigillose; pappi persistent, outer setiform scales (0.250.5 mm; rarely present) plus 2 series of 2545 longer , barbellate bristles , mid apically attenuate, 9095% length of inner, inner apically weakly to strongly clavate [(0.5in S. sphacelata) 1.55(7.3) mm]. x = 9.

Species ca. 100: North America, Mexico, South America, Eurasia .

Solidago is found primarily in North America with some South American and Eurasian species (8 in Mexico, 4 in South America, 6-10 in Europe and Asia).

Recent studies on the phylogeny of Astereae and

Solidago have done much to resolve relationships of the goldenrods to each other and to other genera within the tribe (J. J. Zhang 1996; J. C. Semple et al. 1999; R. D. Noyes and L. H. Rieseberg 1999; J. B . Beck et al. 2004). Traditionally the grass-leaved goldenrods, Euthamia, have been included in Solidago; they are well separated within the North American clade. L. C. Anderson and J. B. Creech (1975) presented anatomic reasons for separating the two genera and also Chrysoma, Gundlachia, and Petradoria. The segregate genera Oligoneuron and Brachychaeta fit within Solidago based on anatomy and DNA studies. Brintonia lies outside Solidago based on DNA and morphology. The position of the monophyletic Oreochrysum also appears to lie outside and phylogenetically close to Solidago. G. L. Nesom (1993) placed the flat-topped goldenrods in Oligoneuron. Results from Zhangs study indicate that the flat-topped goldenrods are nested within other goldenrod groups that Nesom included in Solidago. Beck et al. (2004) indicated that further work is needed before a definitive molecular-based phylogeny is available. While the flat-topped goldenrods are readily distinct from other goldenrods on the basis of arrangements of heads , additional features such as double pappus with clavate inner bristles and oligoneurate phyllaries occur in other species of Solidago as well. The flat-topped goldenrods are treated here as Solidago sect. Ptarmicoidei following Semple and K . N. Gandhi (2004). Nesom provided much of the formal subgeneric nomenclature that by and large is followed here; there are some differences in assignment of species to subsections. Semple (2003, 2004) proposed a number of additional new names and combinations used here. J. L. A. Hood and Semple (2003) presented evidence that the pappus of Solidago is not simple , as previously assumed, but is like that of related genera: it is in two series, inner series somewhat clavate and slightly longer, or sometimes in three series with an additional, shorter outer series of few setiform scales.[1]

Physical Description

Species Solidago multiradiata

Plants (3-) 10-30(-80) cm; caudices branched. Stems 1-10(-30+), decumbent to erect , slender, tufted , proximally glabrous or sparsely hairy , densely short-hispido-strigose in arrays. Leaves: basal and proximal cauline petiolate ; petioles winged , margins ciliate ; blades linear-oblanceolate to spatulate , 10-170 × 3-30 mm, serrate to crenate near apices; distal cauline sessile; blades sometimes subclasping stems, ovate to linear-lanceolate, 16-20 × 7-11 mm, margins often distinctly ciliate. Heads 4-75(-100+), not secund , in dense, round-topped corymbiform arrays; branches white villous . Peduncles 5-6 mm, villous; bracteoles 0-2, linear-lanceolate to lanceolate. Involucres 4-8 mm. Phyllaries unequal to subequal , outer linear-lanceolate to lanceolate, lengths ± 2 / 3 inner, margins ciliate, apices acute to attenuate. Ray florets 12-18; laminae 3-4 × 0.5-1 mm. Disc florets 10-35; corollas 3-5 mm, lobes 0.3-1 mm. Cypselae 1.5-4 mm, sparsely to moderately strigose ; pappi 3-4 mm (inner bristles clavate ). 2n = 18, 36. [source]

Solidago multiradiata is the North American species most closely related to S. virgaurea, the type species of the genus, native to mostly arctic and alpine regions of Eurasia . Plants of S. multiradiata from the Rocky Mountains have been treated as var. scopulorum; they differ so little from those of other parts of the range that recognition of the variety without further support does not appear justified.
