Mr Jolm Sadler on the Flowering of Yucca gloriosa, L. 121 



panicles do not spread so mucli. In this last character 

 tliej' resemble Y. aloifolia, figured in " Bot. Mag." in 1815, 

 t. 1700, a species apparently of early introduction into this 

 country from America, as we read of it as having been cul- 

 tivated in the king's garden at Hampton Court in 1696. 



Y. gloriosa was first discovered in Carolina by Micliaux, 

 growing near the sea-coast. It has lung been known in 

 the gardens of Britain, as both Parkinson and Gerard 

 notice it. It was figured in "Bot. Mag." in 1810, t. 1260. 



During the severe winter of 1878-79, the plants had 

 their leaves much broken down by heavy snows, but other- 

 wise they did not suffer. The species is very hardy, and 

 ought to be more extensively planted as an ornamental 

 evergreen, especially in town gardens, as no plant will 

 resist better the evil influences of continual smoke and 

 dust. 



The general flowering of the Yuccas this autumn, in 

 various parts of the country, I attribute to the favourable 

 summer and autumn of last year (1878) for maturing their 

 growths. 



Besides Y. gloriosa, there were other three dwarf species 

 in flower on the Eock Garden at the same time, viz., Y. 

 filamentosa (" Bot. Mag." 1806, t. 900), which was in culti- 

 vation as far back as 1675 ; Y.Jlaccicla, introduced in 1816; 

 and Y. Anhverpensis, a beautiful species, with a panicle of 

 about 2J feet high of handsome cream-coloured flowers. 



The accompanying plate was taken from a photograph of 

 a portion of the Eock Garden, executed by George A. 

 Panton, Esq. The Society is indebted to the proprietors 

 of the " Gardeners' Chronicle" for the electrotype.
