Microsporogenese em um híbrido triplóide de Coffea racemosa Lour. X C. arabica L.
A natural hybrid of Coffea racemosa Lour. (2n=22) and C. arabica L. (2n=44) is triploid (2n=33), intermediate in many characteristics between both species and highly sterile. Frequency of trivalents is smaller in the racemosa than in the canephora hybrid; bivalents, however, are more frequent in the hybrid. Other observations on microsporogenesis are presented and discussed. New hybrids including other species should be obtained and studied before a definite conclusions be drawn as to taxonomical relationships of Coffea species
