TL;DR: These fossils represent the only known occurrence of Diplotropis in the paleobotanical record and confirm the existence of this extant tropical South American genus in southeastern North America by the Middle Eocene (approx. 45 million years B.P.).
Abstract: Fossil legume fruits from two localities in the Middle Eocene Claiborne Formation of western Tennessee and Kentucky are described and assigned to the extant tropical American genus Diplotropis (Papilionoideae, Sophoreae). Morphological and anatomical details of the fossil fruits occur only in extant Diplotropis and in particular indicate a relationship with sect. Racemosa. These fossils represent the only known occurrence of Diplotropis in the paleobotanical record and confirm the existence of this extant tropical South American genus in southeastern North America by the Middle Eocene (approx. 45 million years B.P.). A new fossil species, Diplotropis claibornensis, is described.

TL;DR: The genus Guianodendron is characterized by a radial corolla with auriculate petals; five stamens; reduced ovule number; a straight hypanthium; indehiscent, flattened, and sutural-winged fruits; persistent bracts and bracteoles; leaflets with a papillate abaxial epidermis
Abstract: The new genus Guianodendron Schutz Rodrigues & A. M. G. Azevedo (Leguminosae, Papilionoideae, Sophoreae) from Guyana and the Brazilian state of Amazonas is described and illustrated, and a new combination, Guianodendron praeclarum (Sandwith) Schutz Rodrigues & A. M. G. Azevedo, is made. The genus is characterized by a radial corolla with auriculate petals; five stamens; reduced ovule number; a straight hypanthium; indehiscent, flattened, and sutural-winged fruits; persistent bracts and bracteoles; leaflets with a papillate abaxial epidermis; and ovate to ovate-elliptic markedly striate stipules.

TL;DR: In this article, the seedling morphology of five tree species of the genera Bowdichia, Cyclolobium, Diplotropis, Ormosia, and Poecilanthe is described and illustrated.
Abstract: This work aims to describe, illustrate and compare the seedling morphology of five tree species of the genera Bowdichia, Cyclolobium, Diplotropis, Ormosia, and Poecilanthe, which belong to the genistoid clade (Leguminosae Papilionoideae). Phanero-epigeal-foliaceous seedlings are found in Bowdichia virgilioides Kunth, Cyclolobium brasiliense Benth. has phanero-epigeal-reserve seedlings, while Ormosia arborea (Vell.) Harms, Diplotropis martiusii Benth., and Poecilanthe parviflora Benth. possess crypto-hypogeal-reserve seedlings. Some other relevant seedling morphological characters are discussed and compared with those of previously studied species in these genera.

TL;DR: Three new records of the snake Leptophis diplotropis are reported from the southeastern and northern regions of Hidalgo State, Mexico, and represent the best knowledge of its distribution in the Sierra Madre Oriental.
Abstract: We report three new records of the snake Leptophis diplotropis from the southeastern and northern regions of Hidalgo State, Mexico. These records represent the first observations of this species in the state of Hidalgo, and represent a range extension of 122.7 km north from the nearest record in Tochimilco, Puebla, Mexico. These new records of L. diplotropis represent the best knowledge of its distribution in the Sierra Madre Oriental.
