mation that we possess on the subject is insufficient to enable 
us to form a positive opinion as to whether it is distinct or 
not. ; 
51. NAGELIA denticulata. 
This plant, the Cotoneaster denticulata of Mr. Bentham, 
has all the structure of that genus in its flowers, and much 
of its habit; but its fruit proves it to be a new genus, which 
I trust may bear the name of the ingenious Mr. Nägeli, the 
fellow-worker of Schleiden in Botanical investigation. The 
fruit is a very pale pink colour, about as large as a pistol ball, 
with a brittle semi-transparent flesh, and the thin putamen of 
a Pyrus instead of the hard bony stone of a Cotoneaster. 
It may be defined as follows—Naceuia. Petala parva, 
patula. Stamina 10-15. Carpella 2, dorso calyci adnata, 
ventre libera, ovulis 2 collateralibus ascendentibus. Pomum 
sphæroideum, calyce coronatum, carnosum, fragile, endo- 
carpio membranaceo. Semina cuique loculo 2, compressa, 
castanea, ascendentia. Cotyledones tenues plano-convexæ.— 
Frutex Cotoneasteris vultu, canescens ; sepalis semimembra- 
naceis; petalis calyce longioribus patentibus. 
52. SCILLA pubens. 
Welwitsch in litteris. 
Under this name the Horticultural Society received from 
the Duke of Palmella’s Garden, at Lumiar near Lisbon, a 
plant which appears undistinguishable from Sc. Peruviana, 
except by being much smaller in all its parts. The flowers 
have the ‘same grey-blue colour and corymbose arrangement, 
with long narrow membranous bracts curving inwards at the 
end. 
53. SCILLA Bertolonii. 
Duby Bot. Gall. 465. 
This also has been sent from the Lumiar Garden by the 
Duke of Palmella. Dr. Welwitsch seems to have rightly 
distinguished it from Sc. italica, to which it-is generally 
referred. It is quite a different thing with a small number
