Chromosome Numbers in the Rutaceae

Naturevolume 175page1125 (1955) | Download Citation



ORIGINAL chromosome counts for three members of the subfamily Rutoideae of the family Rutaceae are given as follows. Correa backhousiana has n = 16, in agreement with the counts for three other species of Correa found by Smith-White1. Evodia danielli has n = 40, this count differing from that found by Bowden2, who gives n = 36 for material grown on the Blandy Experimental Farm, University of Virginia. My material, originally obtained from North China, is now growing in the Royal Botanic Gardens, Kew. Its chromosome number suggests aneuploidy. It is interesting to note the apparent existence of chromosome races within the species Evodia danielli. Choisya ternata has n = 27—a first count for the genus.
