NOTE ON THE MORPHOLOGY OF THE FRUIT OF LONI- 
CERA CAERULEA. 
ALFRED REHDER. 
Ir seems strange that such a widely distributed and well known 
plant as Lonicera caerulea should be so little known in regard to the 
morphological structure of its fruit, that even in the most recent 
manuals and floras as well of this country as of Europe the description 
of the ovaries and fruits is incorrectly given. ‘The fruit is described 
everywhere as consisting of two connate berries, but a dissection will 
show at once, even without the aid of a magnifying glass, that this is 
not the case; the ovaries are entirely separated from each other and 
remain so until maturity, the bractlets, however, are united into a 
cupula tightly enveloping the ovaries the whole thus presenting the 
appearance of perfectly united ovaries without bractlets which in fact 
are generally described as wanting. 
There have been a few botanists who described correctly the ovaries 
and fruits of this Lonicera, but their statements were overlooked and 
the old erroneous conception based on superficial observation has 
remained the current one until today. The first correct description 
as far as I know was given by Petermann in 1849 (Deutschlands Flora 
260, pl. 41, fig. 323, К-Т) as follows: Die vier Deckblättchen zu einer 
die zwei Fruchtknoten eng und günzlich umschliessenden und endlich 
zugleich beerenartig werdenden Hülle verwachsen und so nur einen 
Fruchtknoten darstellend [The four bractlets connate into a cupula 
enclosing tightly and completely the two ovaries and finally becoming
