The genus Gesneria, the type of the family Gesneriaceae, 
was founded by Linnaeus on two West Indian species, 
G. humilis and G. tomentosa, published in his Species 
Plantarum, ed. 1, 1753, p. 612. During the succeeding 
70 years many additional species were described, and it at 
length became evident that species belonging to several 
distinct genera were included under Gesneria. Martius 
(Nov. Gen. et Sp. vol. iii. 1829, p. 27) accordingly dis- 
tinguished three genera, one of which was based on G. 
humilis, and a second on G. tomentosa, whilst the third 
included the great majority of the described species, namely, 
those provided with tuberous rootstocks. Instead of. 
retaining the name Gesneria for one of the original species, 
Martius proposed the new generic names Conradia and 
Rytidophyllum for G. humilis and G. tomentosa, respectively, 
and applied Linnaeus’s generic name, modified to Gesnera,
