L. Grefferi is a South European plant, with a very ex- 
tended geographical distribution, from the Azores and 
Canaries to Portugal and Morocco, and thence eastward to 
Asia Minor and Northern Syria. It does not occur anywhere 
north of the Alps except in Western France, but has been 
introduced into South America and other countries. It 
affects wet places, and when grown in a pot standing in a 
tank or pan of water, it forms a strikingly ornamental plant 
from the profusion of its bright pink blossoms, which stud 
the numerous slender branches, and which appear in suc- 
cession for several weeks. The figure published as L. Greef- 
ferii in Loddige’s Botanical Cabinet is unrecognizable, and 
from the small flowers and opposite leaves probably repre- 
sents L. hypopifolium, L. The figure of L. flecuosum, Lag., 
in Regel’s Gartenflora, again, has most of the leaves opposite, 
and the petals very narrow, not like those of L. Greefferi.
