Trigonella berythea

First published in Pierre Edmond Boissier's Diagnoses plantarum Orientalium novarum in 1856. The plant is annual with white hairs sparsely scattered on the branches and petioles, especially hairy on the upper side. The stems are erect or ascending, sparsely branched. The stipules are ovate, with a very short, acuminated tip, attached to the petiole at the lower part of the stipule. The petiole is equal in length to or longer than the leaflets, which are obovate, with a cuneate base, and have the upper side slightly obtuse and only obscurely dentate. The sepal is tubular, cylindrical, with lanceolate-subulate teeth that are almost subequal. The petal is almost double the length of the sepal, the legumes are straight, linear, subcompressed, longitudinally pressed parallel, and slightly wrinkled, with a beak about half its length, abruptly shortened at the end. This species is closely related to Trigonella foenum-graecum but differs from it in the narrower and longer stipules, the oblong-spathulate leaflets with ciliate teeth, the legumes which are less compressed and have a more strongly marked reticulated surface, traversed by fine nerves that are somewhat distant from each other.
