Distribution
Sloanea hatschbachii is known only from the type locality in the state of Paraná, municipality of Paranaguá.
Ecology
Atlantic rainforest; coastal plain.
Conservation
This species was first collected in 1968. However, during a field expedition to Paraná State in October 2006, the authors could not find it. Houses appear to have been built on the site, which was originally coastal plain vegetation. Therefore, given the limited amount of material available, Sloaneahatschbachii is classified as Data Deficient (DD) following the IUCN (2001) criteria.
Note

This species is morphologically similar to Sloanealasiocoma K. Schum., but can be distinguished from it by the presence of a larger style, an acuminate extension of the anther connective and longer sepals. S. hatschbachii was defined as a new species based on its reproductive morphology. Vegetatitively it is close to S. lasiocoma but can be differentiated from the latter by the size of the style (c. 7 mm long vs 2.5 – 4 mm long in S. lasiocoma), the shape of the extension of the anther connective (acuminate vs acute in S. lasiocoma) and the length of the sepals (7 – 10 mm long vs 3 – 5 mm long in S. lasiocoma). S. hatschbachii was collected in a coastal plain area that is entirely within the area of occurrence of S. lasiocoma. However, all specimens of S. lasiocoma that were collected in the coastal plain area do not show morphological overlap with the new species.
