Description

A description of Asimina reticulata is provided in The Flora of North America.

Asimina reticulata is a long-lived perennial that reaches 2-4 feet in height.[1] Leaves are simple and alternate[2] with net like veins. [3] It has a rusty orange pubescent.[4]

Distribution

Ecology

Habitat

Asimina reticulata occurs in poorly drained sands of areas such as slash pine and longleaf pine-saw palmetto flatwoods, and is often abundant enough to be classified as an understory dominant.[4] Associated species include Quercus, Pinus, Serenoa repens, Lyonia lucida, L. ferruginea, and Befaria racemosa.[5][4] It has been observed to grow in full sun to partial shade.[6]

The range of A. reticulata and A. speciosa overlaps in the northern Florida peninsula, however they tend to occur in different habitats. A. reticulata is found in poorly drained low pinelands while A. speciosa is found on longleaf pine-turkey oak ridges in well drained sand.[4]

Phenology

It blooms January through December.[2] Flower buds develop as an axillary growth on the new shoot growth of one season and flower the following spring after overwintering.[4] The hairy, ovoid buds develop as axillary growths on the new shoot growth and flower the following spring.[4]

Fire ecology

Following a disturbance such as fire or cutting, A. reticulata will immediately respond by putting up several leafy shoots with forming flower buds that will not open until the following growing season.[4]

Pollination

The following Hymenoptera families and species were observed visiting flowers of Asimina reticulata at Archbold Biological Station:[7]

Halictidae: Lasioglossum nymphalis

Megachilidae: Megachile brevis pseudobrevis

Vespidae: Polistes dorsalis hunteri

Diseases and parasites

A. reticulata is at risk to develop leaf blotch and eye spot.[8]
