Common in thickets on the Peak and in Chaloupe Bay, 

 scrambling over the lower plants, also on Eat Island. 



Known here as " Carapiclio." There was a very tall and 

 stout erect or suberect form, 2| feet high, with thick stems, 

 growing in clefts o£ the rocks at Cape Placelliere. 



Distribution. South America, especially plentiful in Brazil. 



The heads adhere tightly to clothes, &c., by means of the 

 recurved processes on the setse, and in this way the plant gets 

 carried about from place to place.

This is chiefly a woodland plant, forming in the Sapate in open 

 spots large tussocks very like those of Brachypodium sylvaticum, 

 the foliage being very plentiful and dark green. It was plen-

 Griueta and also on the Look-out Hill there Was a smaller half- 

 prostrate form, with geniculate culms. 



The plant is called " Capinche."

On the shores of the sandy bays at Peak Bay, Portuguese Bay, 

 Leao, Chaloupe Bay, S. Antonio Bay, and in the Sapate; 

 common. 



Distribution. Whole tropical world. A very troublesome weed, 

 on account of its prickly burr-like spikelets. 



Zea Mats, L. 



Is extensively cultivated here, and the grain exported to 

 Pernambuco. The husking of the maize and preparing it for 

 export are done by the convicts. One plant we saw had no less 

 than nine full-sized cobs upon it.
