BURGHARDT, Alicia D.; BRIZUELA, M. M.  e  PALACIOS, R. A.. Variability in seedlings of some species of Prosopis (Fabaceae): Searching for morphological descriptors. Multequina [online]. 2000, vol.9, n.1, pp.23-33. ISSN 1852-7329.

Exomorphological characteristics of seedlings of eight species of Prosopis: P. alba, P. nigra, P. alpataco, P. chilensis and P. flexuosa (Series: Chilenses, Section Algarobia) P. hassleri (Series Ruscifoliae, Section Algarobia), P. denudans (Serie Denudantes, Section Algarobia) y P. strombulifera (Section Strombocarpa) were studied. All of them were growing under uniform conditions. This study was made in order to analize relationships between species and to find morphological descriptors to identify the species in the field. Numerical methods (UPGMA and Principal Component Analysis) were applied. They allow to identify the morphological characteristics of seedlings that identify all of the species analized. Morphological variables of shoot of the seedlings are useful as potentially descriptors and provide interesting information about evolutionary and systematic relations in the genus Prosopis.
