' ini.untains of Central and South America, 



species being found at an altitude of over 

 l,"i " 1 t .il"i\e sea level. Geonomas form part of the 

 uiidirgrowth on their native mountains, and are said 

 never to appear in the open country unsheltered by trees 

 of larger growth ; therefore, shade is necessary for them 

 when cult, under glass. 



The old practice of growing (Tconoraas in a very light, 

 peaty soil does not seem to be the only method, for ex- 

 cellent results have been secured by growing them in a 

 good loam, well manured and well drained, giving an 

 abundance of water and a night temperature of 60°. 

 Red spiders and thrips are the most troublesome insects 

 to which these plants are subject, and both of these 

 pests multiply much more rapidly if the plants are kept 

 too warm and dry. 



The most useful species from a commercial point of 

 view is G. UledeUana (G, gracilis), which reminds one 

 of Cocos Weddelliana, but has longer leaflets. Those 

 marked thus (•) are cult, under glass in the North; 

 those marked thus (+) are cult, in S. Calif, only; the 

 others are cult, indoors North and also in S. Calif., ex- 

 cept G. Spixiana, which is cult, only in S. Pla. The 

 picture of G. Spixiaita below is adapted from Martius' 

 work on palms.
