1 84 CAMPANULACE/E. 



P. campanuloides {Cavipamda-like Rampion). — This plant 

 grows about i8 inches high, with erect single stems, terminat- 

 ing in a raceme of blue flowers. The leaves are egg-shaped, 

 sharp-pointed, and toothed. Flowers in June and the two fol- 

 lowing months. Native of the Caucasus. 



P. hemispliaericum {Globular -headed Rampion). — A very 

 dwarf species from Switzerland, rarely exceeding 6 inches 

 high, is somewhat tufted in growth, the stems terminating in 

 dense hemispherical heads of bright-blue flowers, which appear 

 in June and July : best adapted for cultivation on rockwork in 

 light rich loam in a moderately dry position. This is a pretty 

 and interesting plant. 



P. orbiculare {Round-headed Rampion) enjoys a place in the 

 British flora, but is rather rare at home ; it is found, however, 

 plentifully enough in the mountain pastures of central and 

 southern Europe. It varies considerably in height in nature, 

 but in cultivation it averages i foot high. The stems are some- 

 what decumbent at the base, but erect in the upper portion, 

 and terminating in globular heads of violet-coloured flowers, 

 which appear in July and August. It is most suitable for rock- 

 work, but succeeds well in the front lines of mixed borders. 



P. Michelii {Michel's Rampion) has oval flower-heads, which 

 elongate as the flowers open into cylindrical spikes of bright- 

 blue flowers in July and August. It grows from 6 to lo inches 

 high, is adapted for culture on either the rockwork or in the 

 mixed border, and is a pretty and distinct species found in 

 various parts of the south of Europe on mountain pastures. P. 

 scorzonerifoUum and P. angiistissimum differ little in cultivation 

 from P. Michelii as regards colour of flower and the form of the 

 flower-heads ; the former, hov\-ever, has more elongated heads, 

 and the leaves, on longer stalks, are rather broader. 



P. Scheuchzeri {Scheuchze?-' s Rampion) grows about 6 or 9 

 inches high, with broadly-lance-shaped leaves and globular 

 heads of flower, opening in May, June, and July. A variety 

 with shorter and rather broader leaves and shorter bracts, 

 named P. S. Char??ielii, and often distinguished as a species, is 

 not sufficiently distinct floriculturally to be desirable in any 

 but botanical collections. Both forms are excellent rockwork 

 plants, and are also adapted for the front lines of mixed borders. 



P. spicatum {Spiked Rampion). — The plant grows about 18 

 inches or 2 feet high. The stems are erect, thinly clothed with 

 toothed sharply-lance-shaped leaves. The flower-heads are 

 shortly and broadly spike-like. The flowers are dull white. A 

 tolerable plant for the mixed border ; but it will probably be 

 found more useful for naturalising in open woods, where the
