It may seem not quite correct to call L. prolifera a new combination, 
as this very name had been published already in 1840, but then it was 
not accompanied by a description nor by a reference to an earlier 
description and therefore can as a nomen nudum not be considered a 
valid name. ‘The specific name first. became valid in 1864 with 
Caprifolium proliferum which is accompanied by a sufficient 
description. 
Another American Lonicera which has to receive a new name is 
Lonicera flavescens Small, Fl. Southeast. U. 5. 1126 (1903) ,as there 
exists an older homonym in L. flavescens D. Gartenfl. XXXVII.7 
(1888). A new name was proposed soon after the publication of the 
younger homonym by Professor T, D. A. Cockerell in a letter preserved 
in the herbarium of the New York Botanical Garden with the tvpe 
specimen and as it has not yet been published it may be put on record 
here. 
Lonicera flavida Cockerell in litt., nom. nov.— L. flavescens Small, 
Fl. Southeast. U. S. 1126. 1903, not Dippel. L. flavida is closely 
related to L. flava Sims and intermediate between that species and L. 
prolifera (Kirchn.) Rehd. From L. flava it differs chiefly in the paler 
color of the corolla, the shorter tube with the throat pubescent inside 
and the acute and not chartaceous-margined leaves, while from L. pro- 
lifera it is easily distinguished by its acute, thin leaves, not glaucous 
above, the slenderer and longer corolla-tube and the shorter inflores- 
cence. The species seems to be rather local and is known only from 
a few localities in Tennessee and Kentucky; the type is from the 
Cumberland Mountain in Franklin Co., Tennessee.
