Naturalisation in Extra-Tropical Countries. 241 



Gomphrena canescens, R. Brown. 



Tropical and sub-tropical Australia. Annual or of short duration. 

 Mr. Joseph Bradshaw singles this species out as a pasture-herb, 

 which horses particularly consume with predilection. 



Gonioma Kamassi, E. Meyer. 



South- Africa. This small tree furnishes the yellow Kamassi-wood, 

 much sought for carpenters' tools, planes and other select articles of 

 wood-work, also for wood-engraving, according to Dr. Pappe. Flowers 

 deliciously fragrant. The bark contains a pleasantly bitter tonic 

 principle [Prof. MacOwan]. 



Gordonia Lasianthus, Linne. 



The Loblolly-Bay. South-Eastern North- America. A handsome 

 tree, growing to a height of 60 feet ; flowers snowy white. The wood 

 is extremely light, of a rosy hue and fine silky texture, but unfit for 

 exposure. The bark is extensively employed for tanning in the 

 Southern States. Available for swampy coast-lands. 



Gossypitun arboreum, Linne.* 



The Tree-Cotton. Upper Egypt, according to A. de Candolle, 

 seemingly also Abyssinia, Sennaar and thence to Upper Guinea. 

 A tall perennial species, but not forming a real tree, yielding cotton 

 in the first season. Leaves long-lobed. Bracts with few teeth. 

 Petals yellow, or in age pink or purple. Seeds brown, disconnected, 

 after the removal of the cotton-fibre greenish-velvety. The cotton 

 of long staple, but also a variety occurs with short staple. The 

 New Orleans cotton (G. sanguineum, Hasskarl) belongs to this species. 

 This cotton-fibre is crisp, white, opaque and not easily separable. 

 All Gossypiums can be regarded as honey-plants. 



Gossypium Barbadense, Linne".* 



Sea-Island Cotton. From Mexico to Peru and Brazil. Leaves 

 long-lobed. Petals yellow. Seeds disconnected, black, after the 

 removal of the cotton-fibre naked. The cotton of this species is very 

 long, easily separable, of a silky lustre and always white. This 

 species requires low-lying coast-tracts for attaining to perfection. 

 Stands drought well [T. R. Sim]. Perennial, but yielding like the rest 

 a crop already in the first season. Cultivated largely in the Southern 

 States of North-America, also in South-Europe, Central and North- 

 Africa, Queensland and various other countries. The cotton-harvest 

 of 1885 in the United States came to fully 6j million bales, at about 

 450 Ibs. each [J. R. Dodge] ; the area there under cotton-cultivation 

 in that year was 18,300,865 acres. G. Kirkii (Masters), from Dar 

 Salam, may be a wild state of G. Barbadeuse. Another primitive 

 type of this genus in tropical Africa is G. anomalum, according to 

 Dr. Welwitch. The " Kidney- cotton " is a variety with more
