The epithet of this new species is a reference to its compact leaf rosette due to the comparatively shorter and densely rosulate
leaves, which is a striking distinctive character of A.
; capitulescences of few capitula Adenocaulon 16b.
1 mm wide at base, the basal ones 3-10 mm apart, antrorse (upper ones) to retrorse (basal ones) uncinate; fascicles 7 to 11 in number, polystichously arranged, suberect, sessile, globose-capitate, strobilate, densely rosulate
, 12-15 mm long (excluding the petals), 14-17 mm in diameter, 7 to 12-flowered; floral bracts broadly triangular-ovate, acuminate, slightly carinate toward the apex, equaling to slightly shorter than the sepals, but recurved and distinctly exposing them, green, nerved, inconspicuously and sparsely white-lepidote but soon glabrous, 10-13 x 8-10 mm, subdensely spinulose, spines irregularly curved, 0.
Leaves 10 to 14 in number, rosulate
, subdensely arranged and forming a distinct rosette before anthesis and afterwards, sheaths inconspicuous, blades narrowly triangular-lanceolate, 9-11 cm long, 0.
Leaves alternate to rosulate
, entire to pinnatisect, rarely spiny, glabrous to pubescent.
Leaves pubescent; basal leaves rosulate
; petiolate; blades linear to ovate, pinnately veined, margin entire to partite; upper leaves numerous, similar to the basal ones but reduced, or lacking; sessile.
Leaves 17 to 20 in number, densely rosulate
, suberect, forming a funnelform rosette; sheaths ovate-elliptic, 13-18 x 10 cm, densely and minutely brown-lepidote on both sides, thinly coriaceous, dark castaneous on both side and mainly abaxially, except for the green and purple spotted apex, blades sublinear, slightly narrowed toward the apex, 25-30 x 4.
Leaves densely rosulate
, 20 to 35 in number, erect to spreading, 30-45 cm long: leaf sheaths narrowly elliptic, 45-65 x 20-30 mm, thin, nerved, sparsely punctate lepidote, more so abaxially, somewhat castaneous; leaf blades linear lanceolate, attenuate, 10-16 mm wide, thin coriaceous, nerved, sparsely punctate lepidote throughout, light green or green tinged reddish.
, laxly spreading, 12 to 18 in number, 30-45 cm long, thin coriaceous.
Leaves 25 in number, densely rosulate
, suberect, forming a broadly crateriform rosette; sheaths broadly elliptic-ovate, ca.
Leaves 20 to 25 in number, densely rosulate
, suberect, forming a funnelform rosette much narrowed at the base and broader above; sheaths suborbicular, ca.
6, laxly rosulate
and forming a distinct rosette before anthesis and afterwards, the upper leaves not distinguishable from the scape bracts; sheaths inconspicuous, subreniform, ca.
