Growth Form: Shrubs, closely grayish pubescent with stellate and simple glandular hairs.

Stems:

Roots:

Leaves: Leaves simple. Alternate. Blades deeply cordate–ovate, 7–12 cm long. Apex acute to acuminate. Surfaces grayish-green, pubescent with stellate and simple glandular hairs. Margins crenate–dentate. Petioles about as long as blades, sometimes pilose with simple hairs. Stipules usually present.

Flowers: Flowers solitary or paired in the leaf axils, exceeded by the leaves, pedicels 1.5-4 cm long, articulate with the calyx sometimes pilose with simple hairs and stellate and glandular pubescent; involucel absent. Flowers bisexual (perfect). Calyx cup-shaped to suburceolate, 1–1.5 cm long; 5-lobed, lobes dentate, 1–3 mm long, pubescent within, valvate in bud. Petals included in calyx, greenish with brighter green, inflexed margins, lower surface reddish, 0.5–1 cm long, up to 9 mm wide. Stamens 5 to numberous, monadelphous, forming a staminal column, staminal column exserted, whitish to yellowish, 2–2.8 cm long; antheriferous in a terminal cluster; anthers monothecal. Pollen globose, echinate. Ovary superior, (1-)3-celled to many-celled, carpels 5 to numerous, borne in a single whorl or rarely seemingly superposed whorls; ovule placentation axile, each with 2-9 ovules in a vertical row; style exceeding the staminal column; style branches coral-colored, as many as carpels; stigmas terminal, capitate, green, scarcely expanded.

Fruit: Schizocarps often tardily separating; cylindrical; 8–10 mm long; 10–13 mm in diameter; pilose; mericarps usually oblong in lateral view; 8–9; 8–10 mm long; apex acute; lateral walls usually smooth; loculicidal dehiscence complete or partial.

Elevation Range: 210–520 m.

Historical Distribution

Uses and Culture

USES

PROPAGATION/CULTIVATION

  • The seeds of Abutilon eremitopetalum are contained in a cylindrical fruit about 1/2 inch in diameter. The fruit is dry when mature and splits into 8 or 9 segments. The 1/16 inch seeds are somewhat kidney-shaped and covered with white or brown fuzz.
  • Abutilon sp. have a high germination rate (95%). Soaking shortens the germination time from 3 to 6 months for untreated seed to 2 to 4 weeks for soaked seeds. Soaking recommendations vary from 1 to 24 hours using either room temperature or hot water. Soak the seeds until they sink, and discard any that float. Seeds should be sown 1/8 inch deep in a well-draining medium such as 3 parts #2 perlite to 1 part #4 Sunshine Mix or 1 part peat to 1 part perlite to 1 part soil. Keep containers in part shade until seeds germinate.
  • Seed should be dried before being stored. Storage recommendations vary; silica gel and refrigeration may improve the length of time seeds remain viable. Ragone reports 65% germination rate for seeds that had been stored with desiccant at ambient temperature (80 degrees F) and humidity (25%) for 3 months. These seeds were soaked in cold water for 1/2 hour before sowing and took 4 months to germinate. In this report, germination percentages for all seeds stored longer than 3 months dropped to almost zero regardless of treatment before sowing.
