396 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 



family, clinging like the ivy, and, like it, forming an evergreen 

 screen. 



Aristolochiace,e. — Aristolochia Sipho is a thoroughly hardy 

 climber, but deciduous, and stands smoke well. 



LAURiNEiE. — Umbellularia califomica is a scented-leaved small 

 shrub here, and has proved hardy, though it was badly nipped in 

 this last wind ; and Laurus nobilis gets on very well also. 



Thymel.eace^;. — In this family there are the several species of 

 Daphne, which are small, hardy, and very pretty shrubs. 



EljEAGNACE.e. — There are no more beautiful evergreens than 

 the species of Elceagnus, E. argentea, pungens, and so forth, 

 and they pass through many varieties. We have them growing 

 well upon a wall, but I am sure they would do equally well 

 planted out. Then the sea-buckthorn is a good hardy plant, and 

 it is very pretty alike in leaf and fruit, and its ally, Shepherdia, is 

 nearly as pretty. 



Euphorbiace^e. — Here we have all the different kinds of box; 

 and of low-creeping shrubs Pachysandra is amongst the best. 



Urticace^e. — Ulmus, in all its forms, grows well. Zelkowa is 

 also a good small tree : it does not get very high with us ; and 

 there are several species of Celtis which do well. The mulberry 

 thrives, but it does not, as a standard, grow to any 3ize with us ; 

 on the walls it grows much better. The oriental plane does 

 fairly well with us, the occidental not at all. 



Juglandejs. — The caryas grow into small trees with us, and 

 so do the walnuts, and also Pterocarya. 



MyricacejE. — Two or three of the myricas ax-e quite hardy, 

 and very pi-etty small shrubs they are. 



Cupulifer^e. — Of Betula and Alnus there are many species 

 thoroughly hardy and resistant. Carpinus in two or three 

 species also does well, and so does Corylus. Ostryopsis and 

 Ostrya also thrive. 



Of oaks there are plenty good species for our climate. Many 

 of these in our Garden have not had a fair chance. Where they 

 have, almost the whole of them have done well. The oak to 

 which you refer is probably the Hungarian oak, Quercus conferta. 

 Castanea forms a good tree here, and so does Fagus. 



Salicine^:. — A horde of willows, as well as of poplars, romp 

 with us. The latter particularly form big trees in a very few 

 years. 



GraminEjE. — Several of the bamboos thrive particularly well.
