A hardy shrub, raised by the Horticultural Society from 

 seeds collected in Mexico by Mr. Hartweg. It was found 

 very common on the sandstone hills near Regla, fruiting in 

 October and flowering in May. It appears to be a genuine 

 Cotoneaster, and is the first species of the genus observed in 

 the New World. The leaves are scarcely an inch long, 

 rounded at the point and slightly toothed there, whence its 

 specific name ; on the upper side they are dark green, on the 

 under side grey with down. The flowers are small, and 

 white or pink, in little terminal corymbs somewhat larger 

 than the leaves.

Whether or not this fine Dogwood is hardy is at present 

 uncertain. It is to be hoped that it will prove so, for it has 

 a beautiful foliage ; the leaves being from three to five inches 

 long, smooth and deep green above, hoary with down on the 

 under side. The fruit seems as large as a sloe, and purplish 

 black, covered with bloom. The flowers are in small heads, 

 and are probably not conspicuous. It has been raised by the 

 Horticultural Society, from Mexican seeds sent home by Mr, 

 Hartweg, who found it in ravines near Chico, where it formed 

 a small tree or shrub ; it had previously been met with by 

 Deppe and Schiede near Xalapa.

A very pretty greenhouse shrub, loaded with a profusion 

 of pale red flowers during all the winter and early spring. 

 The Horticultural Society have raised it from Mr. Hartweg's 

 seeds, it having been found by that collector in the form of a 

 shrub four to five feet high, in a place called the " Banco,'* 

 for an explanation of the meaning of Avhich I shall be obliged 

 to any of my Mexican friends. A figure of it will soon ap- 

 pear in this work.
