'' Cypripediuni in the Light of its Segregates,'' by Mr. G. V. 

 Nash. 



Mr. Nash exhibited living plants and herbarium specimens illus- 

 trating the four segregates now recognized by orchidologists, and 

 formerly considered as parts of the genus Cypripediiim. These 

 segregates are : Cypripediiim, Selenipediiini, Papliiopedilum and 

 Phragmipedium. These divide themselves into two groups. In 

 the first group are Cypripediiim and Selenipedium, characterized 

 by the usually long, leafy stem and broad, flat, thin, many-nerved 

 leaves which are convolute in vernation, and the withering peri- 

 anth persistent on the ovary. In Cypripediiim the ovary is 

 I -celled, and the seeds elongate with a thin testa. This genus 

 \s of north temperate distribution, its representatives, about 30 in 

 number, being found in North America, Europe, and Asia. 



The other genus of this group, Selenipedium, has a 3-celled 

 ovary, and the seeds nearly globose with a crustaceous testa. This 

 is found from Panama to northern South America and is rare. It 

 contains only 3 species, which are seldom seen in cultivation. 



Xhe second group is at once recognized by the conduplicate 

 vernation of its long, narrow, fleshy, strap-shaped leaves, and the 

 deciduous perianth. The flowers are borne on scapes, which are 

 rarely somewhat leafy below. To this group belong the remain- 

 ing two genera, PapJiiopediluni and PJiragmipediiim. In the former 

 the ovary is i -celled and the sepals imbricate in the bud. The 

 most evident character, however, differentiating this at once from 

 Phragmipedium, is in the lip, which has the margin of the opening 

 straight not infolded. The scape is also commonly i -flowered, 

 the exception being with more than one. There are some 50 

 species known in this genus, which is entirely Old World, being 

 generally distributed in tropical Asia and the Malay region. 



The genus Phragmipedium is entirely New World, occurring
