12. SiDA ACUTA Burm.

 A cosmopolitan tropical weed. 



13. Urena lobata Linn. 



Great Coco ; in one spot only, in interior of island. 



A cosmopolitan tropical weed, introduction in this case may be 

 attributed to bird agency. It hardly seemed to be indigenous as there 

 were where it was gathered only a few plants. Yet human agency 

 appears impossible : the species is not present at the north-east of Great 

 Coco where once a small clearing was made, nor on Table Island where

Cosmopolitan in the tropics. 



14. Hibiscus Sabdariffa Linn. 



Great Coco only ; as if spontaneous in the small clearing ; one of the

Cultivated in the tropics. 



15. Hibiscus Abelmoschus Linn. 



Table Island only ; common throughout the clearing, escaped from 

 cultivation. 



Cosmopolitan in the tropics. 



16. Hibiscus tiliaceus Linn. 



Table Island ; Great Coco ; Little Coco ; common, especially on the

 swamps. A stunted almost glabrous form occurs on coral-shingle on Jerry

Littoral species, cosmopolitan in the tropics.
