to notice by Captain Winter, who accompanied Sir Francis Drake 

 in the year 1578 to the Straits of Magellan, where it was first discovered. 

 Usually the plant must be grown in a greenhouse or at least under 

 very favourable conditions out of doors, except in the West of England 

 and in Ireland. Here it is planted against the east side of the palm- 

 house, where it has attracted a good deal of attention. It is not showy, 

 but it has some claims to beauty ; indeed it has been spoken of as one 

 of the finest things in the garden. The flowers are of pale yellowish- 

 green white. It belongs to the Magnoliaceae. This specimen is 

 10 ft. 6 in. high and 9 ft. 3 in. through. 



24. Eucalyptus Gunnii Hk. F. (Elwes and Henry, vi. 1639 > B°t- 

 Mag. t. 7808*). Cider Tree or Swamp Gum. 



There are a number of larger trees than this, but there is always 

 interest where history can be recorded. This tree was received from 

 Messrs. Dicksons, of Chester, in 1898 ; in1911.it was 29 ft. high, and it 

 is now 351 ft. high. 



A remarkable plantation of this Eucalyptus was made by the late 

 John Bateman, Esq., of Brightlingsea Hall, Essex, of plants raised 

 from seed received in 1887 from Mr. Shenman in Southern Argentine, 

 who had there naturalized this Tasmanian E. Gunnii. The trees are 

 mentioned as 50 ft. high, with a girth of 3-4 ft., quite unimpaired by 

 wind or frost even with so low a temperature as 5 0 Fahr. There are 

 now many trees planted about the country, and in a few years there 

 should be some interesting reports. In Tasmania the tree is almost 

 confined to exposed moorland at an altitude of 2,000 ft., and will not 

 live at low elevations. It is native also of Victoria and New South 

 Wales. The wood is of little value in Tasmania because of its small size. 



25. Citrus trifoliata L. 



I do not draw attention to this tree as one of the finest. It is 

 only a good example of a very interesting and perhaps important 

 small tree. It is beautiful in its profusion of white flowers in spring, 

 and perhaps important as a parent with the common Orange 

 in producing a fruit tree for the Southern United States, where the 

 common Orange itself is too frequently destroyed by frost. It is in- 

 teresting to me because it explains very clearly the nature of the leaf 

 of the common Orange. The leaf is trifoliolate, and as the stalk of the 

 orange leaf is jointed it seems to show that at this point two lateral 

 leaflets are wanting. The Cambridge specimen, unfortunately, grows 

 where it must be restricted. In 1911 it was 9J ft. high and 13J ft. 

 wide. It is now, after unavoidable cutting back, 9 ft. high and 12 ft. 

 wide. Growing here it seems to show the value of a little protection. 

 A few feet from where it is now is a border upon which it refused to 

 make any progress ; when planted against a plant-house it immediately 

 made rapid progress. It is a native of Japan, and it is there used as 

 a garden plant and for fences. 



* The plant figured in the Botanical Magazine is called var. mo;:!ana, but 

 Maiden points out that_it differs in no way from the type.
