rose, but rather pyramidal. Each flower is full 13 inch in « 
diameter, snow-white. 
** Mr. Fortune speaks of it thus :— This noble species was 
also found in the gardens of the rich in the north of China, 
and will probably prove perfectly hardy in England. There 
is a tree of it in a garden on the island of Chusan at least 
twenty feet high, which, in the month of May every year, is 
covered with its snow-white blossoms. When grafted, it 
blooms on small plants in pots, and is not unlike a white 
Hydrangea, by which name it is known amongst the Chinese. 
“ It is certainly one of the finest hardy shrubs that have 
been introduced. Even in the greenhouse, and in a pot, its 
beauty is conspicuous. Hitherto it has been grown in a 
mixture of loam and sandy peat.” 
While upon this subject it is desirable to advert to some 
observations as to the genus Viburnum, lately made by Dr. 
Wight. In the Calcutta Journal of Natural History this 
distinguished botanist has tlie following remarks, * Ón the 
structure of the Ovarium and generic character of Viburnum." 
* This, judging from the circumstance of Sprengel quot- 
ing Virgil as his authority for the name, seems to be a very 
‘old appellation. © Linnaeus quotes Tournefort as his authority 
for it, but was himself the first to fix its limits by a precise 
definition, which was in these words, “ Pentandria - trigynia. 
Calyx 5-partitus superus. Corolla 5-fida. Bacca 1-sperma.” 
No notice is taken either here or'in the extended natural 
characters of his Genera Plantarum of the ovary. This cha- 
racter passed current among botanical writers until the publi- 
cation of the fourth volume of DeCandolle's Prodromus in 
1830, when he altered it by the addition ofthe word “ abortu,” 
ii Bacca abortu l-sperma,” thereby implying that there were 
in the ovary a plurality of ovules, all except one of which 
aborted in progress towards maturity. This addition has, 
since then, been admitted by all writers, so far as Í am aware, 
except Professors Endlicher and Lindley. The former de- 
scribing the ovary “ Ovarium inferum triloculare. Ovula in 
loculis solitaria ex apice anguli centralis pendula,” but adds, 
£ Bacca abortu unilocularis monosperma," evidently implying
