Abutilon parishii has a woody base with herbaceous branches, the branches and petioles densely stellate-tomentose. Plants usually have long, sparsely leaved stems (Shreve and Wiggins 1994). The cordate leaves are extremely velvety and the reverse side is much paler than the green upper leaf surface. Light orange flowers give way to fruits that persist through the winter.
Plant: subshrub; ca. 1 m tall, the stems minutely glandular-pubescent and with more or less retrorse simple hairs Leaves: ovate (cordate), 3-6 cm long, coarsely dentate, softly matted-pubescent beneath, appressed-strigose above, discolorous, the lower leaves with petioles 2 or more times as long as the blades Flowers: axillary on short (up to 2 cm) pedicels; calyx 6-8 mm long; petals 10-12 mm long. Fruit: FRUITS schizocarp, exceeding the calyx, 8-10 mm diameter, stellate-pubescent; mericarps 6-8, apically apiculate Misc: In mountains; 900-1000 m (3000-3300 ft); Apr-Aug REFERENCES: Fryxell, Paul A. 1994.

Supplemental information (courtesy of David Bertelsen):
A. parishii can be found from 120-595 meters in Mexico and 795-1479 meters in the US.
Based on measurements from 498 plants, leaf blade length ranged from 1.2 -15.2 cm (average=6.3 cm) and the blade width ranged from 0.9-13.5 cm (average=4.1 cm).
Leaves are actually cordate rather than ovate with an acuminate tip that is a key characteristic for this species.
Mericarps range from 5-10, with the average of 942 being 6.8; 72% had 6-7 mericarps. The 1-2 mm points on top of the mericarps are also a key characteristic
Stem measurements: The longest stem measured was 189.2 cm, the average of live stems was 60.7 cm in Mexico and 30 cm in the US. Interestingly the average of dead stems was 58.8 cm in Mexico and 80.3 in the US.
