On first sight this striking plant appears to be distinct from any species of Campanula hitherto described. Further investigation, however, has shown that size alone separates it from Campanula propinqua Fisch. & Mey., a species which was described in 1835 from plants cultivated in the St. Petersburg Botanic Garden from seeds collected in the Persian province of Azerbaijan. Plants from the same source as the type specimen of C. propinqua are preserved in the herbarium at Kew, together with a large number of more recent gatherings of the species. It is possible to arrange the available material in a graduated series according to the size of the corolla, and so perfect is the gradation that it is impossible to draw a line in any one place that would separate the series into two natural groups. Our plant comes at the top of this series, its extreme size probably being due to favourable conditions of cultivation, although one or two of the specimens from wild localities are only very slightly.
