me in general appearance was the P. betulifolia from China. 

 The general shape is roundish, the shoots being long and more 

 or less curved ; the foliage is greyish, the leaves far apart, but 

 plentiful enough ; the fruits are very small. In Pyrus sinensis 

 the fruits are smaller still, being no larger than Olives (in June 

 they were like large Peas). Judging by the profusion of the 

 berries, the tree must be quite a sight when in flower. 



Of the Mock Oranges there is a fine collection. One of the 

 most singular is the plant known'as Falconiera, or Philadelphia 

 Falconieri. The narrow petals give the flowering trusses a very 

 curious appearance ; P. Zeyheri is very near to it, if not identi- 

 cal. P. speciosissimus seems to be related to grandiflorus ; it is 

 very large and very early flowering. P. coronarius Colum- 

 bianus is large and late. P. Leivisii, from the Eocky Moun- 

 tains, is also a late flowerer. Philadelphus microphyllus, from 

 the same place, is alreadyjlistributed, and has even been hybrid- 

 ised in our gardens. 



The Chinese Hydrangea succeeds very well in the moist parts 

 of the Arboretum. So does H. radiata, with leaves silvered 

 underneath. II. arborescens of the Middle States is hardly a 

 shrub, but rather a small tree. 



Among the Cornus, a rare species, Comas Kousa or Benthamia 

 japonica, seems to be very promising. It is a close ally to the 

 American flowering Dogwoods, Cornus florida and Cornus 

 Nuttallii. The Japanese species has bracts two inches across, 

 and more pointed than in C. florida. The effect is very good, 

 and the plant seems vigorous and healthy. 



Among the Diervillas or Weigelas, the two American species 

 are in marked contrast with the Asiatic ones, by reason of the 

 modest colour of the flower — greenish -yellow and red — but the 

 abundance of the branches and the lustrous green abundant 

 foliage make the two species, D. sessiliflora and D. Lonicera, 

 excellent bushes for shrubberies and clumps. 



Two Loniceras I noticed as beautifully fruited. L. hispida 

 has charming fruits in pairs, coral coloured, more than half an 

 inch long and half as broad. L. involucrata, from the States, is 

 late-flowering, and bears fine berries, red and orange coloured. 

 L. Maximowiczii, too, has carmine-coloured fruits in pairs, and 

 is a fine shrub. 



Of the Vacciniete and Ericeae there is a very large collection
