Genista humifusa is a pretty little prostrate shrub with bright 
yellow blossoms, for the choice rockery. 
Ginkgo biloba may serve for a shrub, as it will not be secured 
more than a few feet high and is a slow grower. This sacred 
‘“‘ maiden-hair tree,’ from Northern China, is quite hardy, and 
fruits in France, but not, I think, with us. You shall find nothing

Gleditschia, which sounds like somebody throwing a stone 
through a pane of glass, soon makes a neat little feathery tree. I 
have only G. tricanthos, the honey locust, from the United States ; 
but it has not flowered or set its beans with me. G. Delavayt is a 
splendid species from Yunnan now within our reach. 
The Globularias are neat sub-shrubs from Mediterranean 
shores. They climb the rockery with great agility, and their blue 
flowers, like big jasiones, stud the bush pleasantly in summer.

treasured Salix serpylifola, a willow to its wee catkins, which I 
collected above Zermatt on wet rocks. 
Gonocalyx pulcher, from New Grenada, would probably stand 
against a wall here, but I never see or hear of this fine monotypic
