Common Names in English:
Narrowleaf Saw-Wort, Common Saussurea, Narrow-Leaved Saw-Wort
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.
, 5-120+ cm; herbage

. Stems erect
or branched. Leaves basal or cauline (sometimes cauline only), sessile or petiolate
entire or dentate
to pinnately lobed
to densely tomentose, glandular
. Heads discoid
, borne singly or in corymbiform
arrays. Involucres ovoid
or ± turbinate
. Phyllaries many in 3-5(-10+) series, subequal

to lanceolate, margins entire, toothed
, or lobed, apices obtuse
or acute, appendaged or not, not spine-tipped. Receptacles flat or convex
, epaleate, smooth
, usually subulate-scaly, sometimes bristly
or naked. Florets 10-20; corollas white to blue or purple, tubes
slender, abruptly expanded to throats
short-tailed, apical appendages
linear, acute; style branches: fused portions with minutely hairy
to linear, short-papillate. Cypselae oblong, ± angled
or 4-5-angled, ribs
(when present) smooth or roughened, apices entire, glabrous or minutely glandular, attachment scars
basal; pappi usually of 2 series, outer of readily falling, short bristles
, inner persistent
or falling as unit
, of basally connate
, usually longer
bristles. x = 13, 14, 16, 17, 18, 19?.
Species 300-400: North America, Eurasia , 1 in Australia.
Saussurea is a notoriously difficult, largely Asiatic genus with species boundaries often indistinct.
Species Saussurea angustifolia
Plants 3-50 cm; herbage
when young, ±
. Stems arising from slender rhizomes, usually
or few, ascending
. Leaves basal and cauline, smaller
distally, sessile, blades
to narrowly elliptic
entire or remotely dentate
, apices acute.
Heads 2-10+ in open or crowded corymbiform
1-5 cm). Involucres 9-14 mm.
Phyllaries strongly unequal,
the outer ± ovate
, inner lanceolate, abaxial
usually also tinged dark purplish, pilose
or loosely tomentose; tips
of outer and mid phyllaries acute. Receptacles scaly
8-22; corollas purple, 11-15 m
6-7.5 mm, throats
3-5. mm; anthers
darker purple. Cypselae 3-4 mm; pappus
brownish, outer 1-2 mm, the inner 9-10 mm. [source]
Extreme forms of the varieties of Saussurea angustifolia are distinctive, ranging from slender, erect , subglabrous specimens of var. angustifolia to dwarf , densely pubescent forms of vars. viscida and yukonensis. The extremes are connected by intermediates. As is indicated by the synonymy , little unanimity exists in the interpretation of these taxa. I have chosen to follow S. L. Welsh (1974) in treating S. densa as a variety of S. angustifolia rather than as a distinct species. The extent to which the differences among these taxa are genetic or environmentally induced has not been investigated. [source]
