about six weeks. The Kew experience is.that in plants under 
glass the leaves are green; only in plants grown in the open does 
the foliage here assume a coppery tinge. 
Olearia chathamica is another striking New Zealand plant for 
whose® introduction, in 1908, horticulture is again indebted to 
Captain Dorrien-Smith. This ‘handsome Composite i is not, however, 
met with in New Zealand proper; it is confined to the Chatham 
place, a goal gronp lying further to the east, where it grows in 
compact masses on the cliff edges or scattered about , among the upland 
bogs, along with O. semédentata, another and it is said even more 
handsome member of the ee genus. The material for ee igure 
was supplied by the Rev. A. T. Boscawen, to whom it 
_ given by Capt. Dorrien-Smith and in whose. garden at Litiecn 
near Marazion it flowered in June, 1911. At Ludgvan it has 
proved quite hardy and is readily propagated by means of cuttings. 
Crassula Barklyi is a curious small species which was first 
cainerae in Little. Namaqualand by the late Sir H. Barkly about 
5. The plants figured were, however, some which were presented 
i Kew in January, 1911, by Professor Pearson of Cape Town; they 
formed part of a collection made during the Percy Sladen Expedi- 
- tion, led by Professor Pearson, and were found by Mr. Pillans, one 
of the party, some little distance south-west of Bakhuis. 
The Plums of New York—A copy of this elaborate work,* 
published by the New York Agricultural. Experiment Station, has 
been presented to the Library by Mr. W..P. Hedrich, who is already 
favourably known as the author of a similar volume dealing with the 
merican species and varieties of Vitis, entitled “The Grapes of 
New York.” The of the present volume .is taken. up with 
descriptions of varieties of plums that can be grown in New York 
State, with notes on their origin, history, characteristics and culti- 
vation. It is of quarto size, runs to 628 pages, and is illustrated by 
about one hundred finely executed, coloured portraits of the more 
important stig wot fruit and the flowermg sprays of . some 
American species of Prunus. The plums derived from the: Old: 
World P. distettite, a are still by hae the most important in North 
American gardens, especially in the longer settled States. But 
numerous varieties have been and are being raised by selection and 
hybridisation from the North American species. These are of 
pee uliar interest and value because in many parts of the. United
