From the above concordance, it will be evident that 
Linnaeus’s 19 species of Orchis can be referred to 15 
genera or at least 5 genera; his 6 species of Satyrium to 
6 genera or at least 5 genera; his 15 species of Ophrys 
to 10 genera; his two species of Serapias to 8 genera: 
his 8 species of Arethusa to 8 genera; his two species of 
Cypripedium to 2 genera; his 14 species of H/pidendrum 
to 10 genera. Thus, in a group of species where Linn- 
aeus saw only 7 genera, modern orchidologists see 50. 
This change of viewpoint has come largely from the in- 
troduction into gardens of allied species during the 19th 
century, a consequence both of Kuropean botanical ex- 
ploration outside Europe and of improved methods of 
cultivation, the two together providing living specimens 
for study and greatly stimulating this study. Of the 
species accepted by Linnaeus in 1758, Europe provided 
30, eastern North America 11, Indonesia and the Philip- 
pines 4, Siberia 4, India 6, tropical America 8, Ceylon 
2, China 1; only 4 were previously undescribed species. 
He had a first-hand knowledge of many European spe- 
cies in a living state, but his acquaintance with tropical 
orchids was meagre. He knew his Orchis cubitalis (Peri-
