Abstract

Cypripedium pubescens, C. acaule and C. candidum each have 20 somatic chromosomes; Calypso bulbosa has 32; Habenaria bracteata, H. orbiculata, Orchis spectabilis, and O. rotundifolia each have 42. The numbers of chromosomes as far as counted were constant for genera. [See also HUMPHREY, L. M. The somatic chromosomes of eight species of the Orchidaceae. Proc. Iowa Acad.
