Description:

Abutilon eremitopetalum is a shrub characterized by its close grayish pubescence, which consists of stellate and simple glandular hairs. The leaves are simple and alternate, with deeply cordate-ovate blades measuring 7–12 cm long. The apex of each leaf is acute to acuminate, and the surfaces are grayish-green, covered with stellate and simple glandular hairs. The leaf margins are crenate-dentate. The petioles are about as long as the blades and sometimes pilose with simple hairs. Stipules are usually present. The flowers are solitary or paired in the leaf axils and are exceeded by the leaves. Pedicels measure 1.5-4 cm long and are articulate with the calyx, sometimes pilose with both simple hairs and stellate, glandular pubescence; an involucel is absent. These flowers are bisexual (perfect) and feature a cup-shaped to suburceolate calyx, 1–1.5 cm long, with five dentate lobes, each 1–3 mm long, and pubescent within. The petals are included in the calyx, greenish with brighter green inflexed margins and a reddish lower surface, measuring 0.5–1 cm long and up to 9 mm wide. The stamens are numerous and monadelphous, forming a staminal column 2–2.8 cm long that is exserted, whitish to yellowish, with anthers in a terminal cluster. The ovary is superior, (1-)3-celled to many-celled, with carpels 5 to numerous, and ovules arranged in a vertical row; the style exceeds the staminal column and has coral-colored branches as many as there are carpels; the stigmas are terminal, capitate, green, and scarcely expanded. The fruits are schizocarps that often separate tardily; cylindrical, 8–10 mm long and 10–13 mm in diameter, and pilose. Mericarps are usually oblong in lateral view, 8–9 in number, and 8–10 mm long with an acute apex and smooth lateral walls. Dehiscence is loculicidal, either complete or partial. Seeds are asymmetrically reniform, up to 2.9 mm long, matted with white or brown pubescence, and may or may not contain endosperm. It is found in dry forests at elevations ranging from 210-520 meters.

Federal Status

Endangered species (E) are species that are so rare they’re in danger of becoming extinct.

Threatened species (T) are species that are likely to become endangered within the foreseeable future throughout all or a significant portion of their range.

Species of Concern (SOC) are species about which there are some concerns regarding status and threats, but insufficient information is available to list the species under the Endangered Species Act (ESA).

Plant Extinction Prevention (PEP) is a state status for rare plants that focuses its efforts on species that have fewer than 50 remaining wild individuals.

Storage Behavior

Orthodox seeds (desiccation-tolerant): can be dried to an internal seed moisture of less than 12% water and stored at freezing temperatures.

Intermediate seeds (temperature-sensitive) tend to age faster than orthodox seeds and may have only a 5-year lifespan when stored at -20°C. They are recommended for storage at 5°C.

Recalcitrant seeds (desiccation-sensitive): cannot be stored in a conventional freezer as they cannot survive after drying and/or freezing at -20°C. They are recommended for cryopreservation storage.
