Coburgu, Urumoff, are confined to the Balkan Peninsula 
and Thessaly (Mount Olympus). 2. serbica was originally 
discovered on Mount Zlot in Southern Serbia by Pancic, 
growing on rocks in calcareous soil. It has since been 
found in other parts of Serbia and in Albania, but, as 
pointed out by Adamovic¢, the specimens from Albania, 
collected by Baldacci, have been distributed and recorded 
under the name of 2’. Nathaliae. The record for Bulgaria 
by Velenovsky is shown by Derganc to be based on an 
incorrect identification, the plant supposed to have been 
Ramendia serbica being in reality Haberlea rhodopensis. 
f. Nathaliae, regarded by some authorities as merely a 
variety of /’. serbica, is, according to Adamovié, a distinct 
species, differing in having broadly ovate leaves which 
are narrowed almost equally to base and apex, regularly 
tetramerous flowers, a patelliform corolla and. longer 
anthers. L, serbica has long been in cultivation at Kew, 
where it is established along with 2. pyrenaica in a loose 
stone wall in the Rock Garden, thriving well in a shaded 
situation and flowering annually during May and June. 
A few plants are also grown ina cold frame to flower 
earlier in the Alpine House. It may be propagated by 
its seeds, which ripen freely. The plant from which our 
figure has been prepared was communicated by Sir F. W. 
Moore from the Royal Botanic Garden, Glasnevin, in 
June, 1917,
