1. Papaver dubium L. (blind eyes, longhead poppy)
Pl. 476 a–c; Map

Sap usually
white. Stems 15–60 cm long, moderately pubescent with relatively long,
spreading, broad-based hairs. Basal leaves with the blade 3–8 cm long, 1 or 2
times pinnately deeply lobed (rarely fully compound toward the base), variously
oblanceolate to elliptic or ovate in outline, the ultimate segments lanceolate
to oblong-lanceolate, or narrowly elliptic, tapered to sharply pointed tips,
the margins otherwise entire or with a few coarse teeth, the surfaces and
margins sparsely to densely hairy with relatively coarse hairs. Stem leaves
similar to the basal ones, sessile or short-petiolate, with shorter blades, the
margins sometimes more densely toothed, not clasping the stems at the base.
Flower stalks 12–20 cm long, with relatively long, spreading hairs toward the
base, these grading into appressed hairs toward the tip. Sepals 10–18 mm long,
with relatively coarse, more or less appressed hairs. Petals 15–25 mm long, red
to pinkish red or orange, usually with a pronounced dark spot at the base.
Anthers dark purple to black. Stigmatic crown with (4–)7–9 lobes. Fruits 12–22
mm long, narrowly obovoid, longitudinally lined or slightly ribbed, glabrous, occasionally
slightly glaucous when young. 2n=42. May–July.
Introduced,
uncommon and sporadic, mostly in the southwestern portion of the state (native
of Europe, Asia; introduced widely but sporadically in the eastern and
northwestern U.S., Canada). Glades; also pastures, railroads, roadsides, and
open, disturbed areas.
Kiger (1997)
noted that in its native range, P. dubium is a polyploid complex that
has been split into several morphologically intergrading subspecies. He stated
that these have no geographic integrity among populations introduced in North
America and thus are impossible to adequately discriminate and thus unworthy of
formal recognition.
