疏叶合叶木Cardoso被认为是鼠足组的一个新种。该新种似乎与Viscidulae系列有关，因为它呈现草质，纤细的枝，密被粘性腺毛覆盖。然而，它拥有的果实比这个系列预期的要大得多。根据直立习性可对Aeschynomene sabulicola进行诊断，达c。3.5花序极叉开，花远生，果具1个近肾形，长13-14 × 7-8毫米。该物种仅分布于巴西东北部巴伊亚州圣弗朗西斯科河流域中部沿着的大陆沙丘地区。© 2008 The Linnean Society of伦敦，Botanical Journal of the Linnean Society，2008，157，749-753.
Aeschynomene sabulicola L.P. Queiroz & D. Cardoso is proposed as a new species of the section Ochopodium. This new species seems to be related to the series Viscidulae, as it presents herbaceous, slender branches, densely covered by viscid glandular hairs. However, it possesses fruits much larger than expected for this series. Aeschynomene sabulicola can be diagnosed by the erect habit, reaching c. 3.5 m high, inflorescences divaricate and horizontal with remote flowers, and fruits with only one subreniform article, this measuring 13–14 × 7–8 mm. The species occurs only in a continental sand dune area along the middle Sao Francisco River basin in the State of Bahia, north-eastern Brazil. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 157, 749–753.
