BOTANY 



' Among plants of gregarious occurrence I particularly noted Echium, Origanum, Rubia 

 and Erythrtea Centaurium ; Clematis in more or less artificial plantations was observed climb- 

 ing to a height of 30 to 40 feet, and Cuscuta Epithymum, on furze overhanging a terrace wall, 

 was at least 6 or 7 feet long and very effective. Calystegia silvatica, a native of south-eastern 

 Europe, having pure white flowers twice the size of those of C. sepium, has become established 

 among the furze and brambles opposite " Fern Bank," Kingswear, and in several other places, 

 where it forms a fine show from early morning until it closes its diurnal flowers about midday.'
