Abstract
The chromosome number was determined in eleven recently-described species of Arachis belonging to five different taxonomie sections. Two new species of section Arachis, A. Gregoryi and A. Krapovickasii, present 2n=20 chromosomes and lack the small 'A' pair, while A. linearifolia and A. Schininii have 2n=20, including the small 'A' pair of chromosomes, typical of the A genome of A hypogaea. Arachis Schininii , previously listed under A. Hoehnei, a species lacking this pair of chromosomes, has many morphological differences, and is therefore considered to be a new species. Arachis submarginata (sect. Extranervosae), A. Pflugeae and A. Hassleri (sect. Pmcumbentes), and A. seridoensis and A. interrupta (sect. Heteranthae) also have 2n=20. One species of section Rhizomatosae , A nitida , is tetraploid (2n=40), but is morphologically distinct from the other tetraploids in this section. The new species of section Erectoides, A porphyrocaiyx, shows 2n=18. This is the first count of 2n=18 chromosomes for an Arachis species outside section Arachis and its origin is probably not associated with the origin of the 1 8 chromosomes occurring in three species of section Arachis.
