Habit | Shrubs, to 1.5 m; crown much branched. | Shrubs or low trees, to 6 m; trunks slender, at most to 10 cm diam. |
Branches | spreading-ascending, slender; new shoots red-brown, distally minutely reddish tomentose. |
|
Shoots | red-brown to tan, distally red or pale-hairy, becoming gray-brown, distally glabrous or sparsely pale-hairy. |

Leaves | blade oblong to elliptic or narrowly obovate, 5-8 cm, leathery, base abruptly and broadly cuneate or rounded, margins strongly to moderately revolute, apex acute to broadly rounded, occasionally notched; surfaces abaxially densely orange-hairy, becoming sparsely so on veins, adaxially sparsely orange-hairy, becoming glabrous and often glaucous. |
blade obovate to oblanceolate, 6-15(-20) cm, membranous, rarely leathery, base narrowly to broadly cuneate, margins barely revolute, apex acute to acuminate; surfaces abaxially minutely rusty-tomentose, aging hairy on veins only, adaxially puberulent on veins, aging glabrous. |

from previous year's shoots before or during new leaf emergence; peduncle 0.3-0.8 cm, tomentose, hairs red-brown to tan; bracteoles 1(-2), basal, usually ovate-triangular, rarely over 2-3 mm, hairy. |
Flowers | 1-3 per node, fragrant, large; sepals triangular, 8-10 mm, abaxially orange-puberulent; outer petals spreading, white or cream, narrowly oblong to obovate, 2.5-6 cm, abaxially puberulent on veins; inner petals incurved, white, yellowish white, rarely pink or cherry red, mostly with deep maroon to purple corrugate zone, lance-hastate, 1/3-1/2 length of outer petals, fleshier, base saccate, margins revolute; pistils 3-8. |
maroon, rarely yellow, faintly fetid, 1-1.7 cm diam.; sepals triangular-deltate, 4-7 mm, abaxially rusty-tomentose; outer petals oblong to ovate, 1-1. |

Discussion | Asimina reticulata hybridizes with A. incana and A. pygmaea. Hybrids with the latter frequently have cherry-red inner petals. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Asimina parviflora is primarily a miniature version of A. triloba in flower, shoot, and leaf; it reaches tree size only in the karst country of Florida. Peduncles at anthesis are often so short that flowers appear sessile. Pubescence is of a lighter red or brown than that of A. triloba. Putative hybrids between the two have been observed in northern Alabama. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
