Begonia Baumanni belongs to the tuberous-rhizomed 
group of the genus, which includes B. Veitchii, Hk. f. (Tab. 
5663), B. Clarkei, Hk. f. (Tab. 5675) and B. roseflora, 
Hk, f. (Tab. 5680), and some of which have proved to be, 
as I ventured to predict in publishing B. Vettehit in 
1867, amongst the most ornamental of border plants. 
They have been referred by myself and others to tho 
section Huszia, A.DC., which contains species with 
different types of stigmas; those of B. Veitchii, for in- 
stance, having the arms elongate, with a spiral line of 
stigmatic papilla, whilst those of B. resexflora and 
Baumanni have short, broadly truncate stigmas, cleft on 
the ventral side, but not 2-lobed, with undulate convolute 
margins, and the papillz are confined to the truncate upper 
margins. Recently M. Fourier has proposed (* Bull. 
Soc. Centr. d’Hortic. de France,” Ser. 3) (1879) a new 
grouping of the tuberous Begonias, according to which B. 
Baumanni is placed in section Lemoinex, characterized by 
JUNE lst, 1897.
