1923] WILSON, NORTHERN TREES IN SOUTHERN LANDS 77 



this genus is much needed. I collected herbarium material in different 

 places but have not yet had time to examine it. Five species I know 

 sufficiently well to be sure of their identity but the others I shall mention 

 under the names they are known by in particular localities. The most 



grown 



Macrocarpa" tree 



any generic name. In Kenya Colony in equatorial Africa the name is 

 changed to " Microcarpa. " The general application of the specific name 

 either rightly or wrongly rendered as a vernacular name is proof of the 

 popularity of this tree. It is as a hedge plant that it is most widely em- 

 ployed but as an ornamental tree it has been planted in great numbers. 

 Though it does not thrive everywhere in the antipodes it succeeds through- 

 out a greater area than almost any other exotic tree. In Western Australia 

 it has a bad habit of dying suddenly and hedges of it are often patchy 

 as blocks of it die in the hedgerow. On this account it is losing popularity 

 in that state. In eastern Australia it flourishes and is a most popular 

 hedge plant. It is also much planted in New Zealand and South Africa. 

 I saw many fine specimen trees in the antipodes, the grandest I think are 

 growing in the grounds round the Salmon ponds, New 

 They are not much more than fifty years old and are fully 80 feet tall and 

 12 feet in girth of trunk. For forest planting the Cupressus as yet have 

 scarcely been employed but the fact that their wood is very lasting in the 

 ground and therefore most suitable for fencing makes them valuable. I 

 saw one or two small experimental stands and the rate of growth was 

 quite satisfactory. At Tokai, near Cape Town, there are small stands of 

 several species but the names are confused. The Mediterranean species 

 (C. sempervirens L.) and its fastigiate form striata Ait. have been much 

 planted as ornamental trees and in general does well in many places in 

 eastern Australia and South Africa. In the vicinity of Adelaide they are 

 notably successful, also at Hobart. For forest planting in South Africa 

 and eastern Australia, the Nepal Cypress (C. torulosa D. Don) and the 

 so-called Portugal Cypress (C. lusitanica Mill.) promise most. At Salis- 

 bury in Rhodesia these are the only two exotic conifers that really thrive 

 and the Nepal Cypress grows faster and better. At Maritzburg both do 

 well and the same is true at the Cape though there the Portugal Cypress 

 is the more common. In New Zealand, South Australia and in Victoria I 

 saw many good trees of both species and at Hobart C. torulosa D. Don is 

 particularly good. Here and there in eastern Australia I saw fine specimen 

 trees of the Chinese C. funebris Endl. but I do not think it has value there 

 for forest planting. The same is true in South Africa. In several places 

 in eastern Australia I saw nice trees of a Cypress known as C. Lindleyi. 

 It has bluish green foliage, hanging branchlets and small fruit. At Nairobi 

 in Kenya Colony, almost on the Equator in central Africa, a species of 

 Cypress from Guatemala thrives better than any other exotic conifer and 

 will certainly prove a useful subject. Trees under the names of C. Goveniana
