TL;DR: Data and phase obtained on a pure morphological basis, as well as on quantitative genetic studies and geographical distribution support the existence of two complexes within the cultivated chickpea, macrosperma and microsperma.
Abstract: A collection of populations and cultivars of Cicer arietinum L. were studied to obtain phenotypic, genotypic and environmental correlation coefficients, and broad sense heritabilities. Principal Component Analyses were performed on phenotypic, genotypic and environmental matrices. Data and phase obtained on a pure morphological basis, as well as on quantitative genetic studies and geographical distribution support the existence of two complexes within the cultivated chickpea, macrosperma and microsperma. These taxa differ in a cluster of complex characters associated with seed. pod and leaf morphology, and they differ in distribution. There is no taxonomic basis to treat these as subspecies. We propose to include C. reticulatum
Lad., the wild chickpea, as a subspecies of C. arietinum, with the cultivated kinds recognized as subspecies arietinum. Race macrosperma was derived from race microsperma through selection during relatively recent times of the evolutionary history of the chickpea.

TL;DR: In this article, a 1:1 complex was used for the determination of trace amounts of palladium in some catalysts and one mineral, and a red-violet 3:1 mixture was used to determine the presence of gold in aqueous ethanolic solution.
