side for some years. Then there are species of Geanothus — 

 Ceanothus americanus and G. azureus are hardy. They may get 

 nipped a little in a bad winter perhaps. So also C. Veitchianus. 

 Their flowers are beautiful. On a wall Geanothus is splendid. I 

 believe that C. americanus is, as a plant in the open, best grown 

 when cut back yearly. 



A.MPELiDEiE. — Of the species of Vitis a great number do well. 

 Many of them, however, do not show the fine colour in their leaves 

 that you get in more southern regions. In this case, as in others, 

 the want of colour is due to our want of summer heat. Of vines 

 that I can guarantee to be quite hardy, there is Vitis amurensis, 

 Coignetice, cordifolia, capreolata, quinquefolia, riparia, and in- 

 constant. 



SAPiNDACEiE. — In this family we have the different species of 

 Jlsculus, several of which are quite hardy and flower freely. Be- 

 sides jEsculus Hippocastanum there is carnea, and /lava, and glabra, 

 and Pavia. A very large number of Acers do well. Amongst 

 them, the Norway maple, of which we have large trees, and its 

 colour in the autumn is beautiful ; and we have also the cut-leaved 

 English maple and the sycamore. There is circinatum, most 

 gorgeously coloured in autumn ; glabrum, dasycarpum, Negundo, 

 which in its variegated form is a very pretty plant, rubrum, and 

 so forth. The Japanese maple (A. palmatum) grows quite well in 

 the open here, but we have not had trial of many of the highly- 

 coloured and variegated forms of it for sufficiently long to enable 

 me to say how far they will succeed well. That they will live I 

 have no doubt. To the same family belong the staphyleas, of 

 which Staphylea pinnata, trifolia, and Colchica are quite hardy. 



Anacardiacejs. — Here we have a number of species of Rhus, 

 and they thrive beautifully and give splendid colouring in autumn 

 — Rhus Cotinus, glabra, and so forth. 



Leguminos^:. — In this family Piptanthus nepalensis is a very 

 charming flowering shrub, quite hardy. And then there are the 

 several species of Laburnum, of Genista, of Ulex, and of Cytisus, 

 many of which are quite hardy, and are beautiful both in their 

 foliage and flower. Wistaria grows quite well on walls here, but it 

 does not flower very freely. Robinias are quite noted town-plants. 

 Coluteas and caraganas are handsome hardy shrubs, and Gledit- 

 schia, as well as Cercis, gives us beautiful small trees. 



Rosacea. — Prunus supplies a wealth of quite hardy flowering 

 trees, which are also, many of them, beautiful by their foliage in
