Description.

Perennial climber apparently with tuberous roots; stem pubescent. Leaves petiolate, 3.5-9 × 3.5-9, sometimes ovate but usually 3-lobed to about halfway or slightly less, lobes elliptic, narrowed at both ends, occasionally ovate or somewhat repand, acute or shortly acuminate, mucronate, base truncate to cordate, often cuneate onto the petiole, adaxially appressed pilose, abaxially softly adpressed silvery-grey pilose; petioles 2-8.5 cm, pubescent. Inflorescence of few-flowered, pedunculate axillary cymes; peduncles usually short, 1-5 cm, pubescent; bracteoles 4-12 mm, filiform; secondary peduncles c. 5 mm; pedicels 5-12 mm, thickened upwards, pubescent; sepals unequal, outer 8-11 × 3 mm, oblong-lanceolate, acute, often mucronate, tomentose, inner 11-14 × 4-5 mm, broadly oblong-elliptic, rounded to retuse, glabrous or pubescent in the centre but with scarious, glabrous margins; corolla 4-6 cm long, funnel-shaped, deep pink, glabrous, limb c. 3 cm diam.

Notes.

Somewhat variable in the density of the indumentum. It differs from Ipomoea eremnobrocha in the narrower, acute, mucronate outer sepals. It is generally more densely hirsute.

Hinton 8120 (K) from Acatitlan, Temascaltepec is correctly identified as this species but the location would appear to be wrong. There was perhaps an error in the labelling.
