Abstract

Two new Randia species are described from the aculeata-complex, characterised by small leaves, flowers and fruits, the later with soft exocarpium. This group apparently has its diversification centre in Mexico represented actually by 19 species and 3 varieties. Randia crucis is a deciduous tree up to 6mhigh in Oaxaca, characterised by terminal pairs of spines and many-flowered lateral inflorescences with very small naked flowers and white tomentose hypanthium. Randia manglaris is a very special shrub of Veracruz, living in the mangrove bush, completely glabrous, characterised by lateral pairs of spines, few-flowered inflorescences and flowers with corolla lobes twice longer than the tube.
