The flowers, however, are larger, and are ovate in outline, instead 

 of being almost lanceolate elliptic, while the glumes are deeper 

 and more blunt, and the fertile glume and palea harder in 

 texture.

Paths of the garden at the Director's House. This was a 

 quite typical prostrate form, similar to the Indian. Another 

 variety, with numerous short lanceolate dark green leaves, an 

 inch long by a quarter broad, and with geniculate stems, grew 

 on Tobacco Point, and a more tufted dwarf form on the slopes 

 of Morro branco. 



The variety appears to be rare in Brazil, though very common 

 in the Old World.

This is the commonest form in South America, and was very 

 plentiful and varied here. A quite typical form occurred on 

 Cape Placelliere and on the north side of Eat Island, and again 

 along the paths in the village. A very large and hairy form grew 

 on the cliffs at Chaloupe Bay. It was about three feet high, with 

 a decumbent base, and the leaf-sheaths were thickly covered with 

 long white hairs a quarter of an inch in length. The flower- 

 spikes also had, in the lower part, a number of similar white 

 hairs on the rhachis, and the spikelets were pubescent. This 

 variety was obtained also by Grlocker at Bahia (no. 216 of his 

 collection).

In a damp spot in the centre of the isle and along the streams
