30 MISSOURI BOTANICAL GARDEN, 
tion is in Willdenow’s Enumeratio Plantarum Horti Bero- 
linensis (1809). 
The subdivision of the genus as proposed by Linné into 
Periclymena and Chamaccerasa (misspelled in the first edi- 
tion of Species Plantarum ‘‘ Chamaecerosa’’) has always 
remained the principal subdivision, though usually with 
the names changed according to De Candolle (1805) into 
Caprifolium and Xylosteum. In his Prodromus (1830), 
De Candolle subdivided the subgenus Xylosteum further 
into Isika, Cuphantha, Chamaecerasus and Nintooa. He 
included Nintooa in Xylosteum, while other botanists, as 
Rafinesque (1836), Maximowicz (1877) and Clarke (1882), 
refer it less happily to Caprifolium to which it is similar 
in habit and partly in the shape of the corolla, but not 
closely allied. By Rafinesque, Nintooa is called Eunemium, 
and Periclymenum (Tourn. ) Kantemon: he apparently had 
forgotten that he had named the same group sixteen years 
earlier Phenianthus. For the American species of Capri- 
folium he proposes a new section Cypheola, which is iden- 
tical with the later Caprifolium § Loniceroides of Spach 
(1839). Another new section was based on L. Jberica by 
Jaubert & Spach (1847) and named Chlamydocarpus. 
Hooker f. & Thomson (1858) separated as Bracteatae 
the Lonicera hispida and allied species; and Maximowicz 
(1877) formed of the red-flowered species of the section 
Chamaecerasus the group Rhodanthae. The latest addi- 
tion to the sections is Vesicaria of Komaroy (1900) 
founded upon L. vesicaria and L. Ferdinandi. Quite 
recently the unnamed sections proposed by Koehne (1893) 
have been adopted with slight changes and named by Zabel 
(1903). Of these only the sections Ochranthae, Subses- 
siliflorae and Ebracteolatae can be considered new. ‘The first 
is substantially the same as Maximowicz’s unnamed second 
section of his Chamaecerasus, but the other two seem too 
heterogeneous to be maintained. 
There can be little difference of opinion about the
