ON JUSSIZA REPENS OF LINNZEUS. 61 
Cotula australis, Hook. Limited to a single station at 
Sierra Madre, where Dr. Hasse found it. 
Crepis biennis, L. <A casual in Sixth Street Park, Los 
Angeles. 
Bellis perennis, L. Once observed on Main Street, Los 
Angeles. 
Here also may be recorded two plants natives of America, 
but accidental introductions in this county. 
Gymnolomia multiflora, B. & H. In 1890 I found some 
specimens growing in the river bed at Los Angeles; and Dr. 
Hasse the same season found one plant at Santa Monica. 
In neither place has it reappeared. 
Dicoria canescens, T. & G. For the last two seasons a 
few specimens have been found on the sand banks near the 
railway bridge, no doubt accidentally introduced from the 
Mohave Desert. 
On Jussiwa repens or Linnzvs. 
By Baron FERDINAND VON MUELLER. 
Will you be so kind, dear Professor Greene, as to publish, in some one 
of the botanical periodicals of your country, the fact that the Jussixa 
repens of American phytographers is not the Linnwan plant that was 
so named; for that has the petals white, except their base (just as in 
Ranunculus aquatilis) as was stated long ago by Rheede and by Ray, in 
their definitions of what afterward became the type of Linnzeus’ species. 
The genuine J. repens is known with certainty only from continental 
India, where the smaller species, with petals always entirely yellow, 
does not exist; but which, however, must approach very near to the 
Indian confines. This is the J. diffusa of Forskaal; and, as Mr. Oliver 
has shown, it is also the African plant, and the same occurs throughout 
Australia. I believe it is also the American plant. Mr. Mohr, of 
Alabama, who, at my suggestion made through Mr. Thomas Meehan, 
investigated the case, reports that in the Southern United States the 
plant called J. repens has always quite yellow petals. 
As the subject is one of some interest from the point of geographical 
distribution, will you kindly make known at an early date your own 
experience in connection with the American Jussixa, and address a note 
on the subject, to Professor Léveillé. 
Regardfully yours, 
Frerp. von MUELLER. 
Melbourne, Australia, 5 Dec., 1892.
