REPORT ON THE BOTANY OF THE ISLANDS OF THE SOUTHERN OCEAN. 161 



Associated with Agrostis ramulosa on the high part of the mountain, where these two 

 grasses formed the chief part of the herbage in Carmichael's time. 



These two species of Agrostis are very distinct, and are not very closely allied to any 

 others except our Agrostis delislei from Amsterdam Island.

Tristan da Cunha. Thouars. 



When at the British Museum we omitted looking up Carmichael's specimen ; but Mr 

 Eidley has obligingly done so, and he writes : " I have looked at the Polypogon, which 

 seems to be of the Polypogon monspeliensis section, near Polypogon napalensis, but with 

 larger flowers. It is rather a stout plant for a Polypogon, and seems to be a distinct 

 species." 



Phalaris cespitosa, Thouars. 



Phalaris cespitosa, Thouars, Esquisse Fl. Trist., p. 37. 



" Panicula pauciflora subspicata, culmo repente stolonifero." 



Tristan da Cunha. Thouars. 



Thouars 's name is not taken up by either Kunth or Steudel, nor does Carmichael include 

 it in his enumeration, and we have no clue to its affinity. The author states that this grass 

 alone sometimes covers large spaces of ground, and to the above brief diagnosis he adds : 

 "Epi long d'un pouce." There is nothing in the collections either of MacGillivray and 

 Milne, or of Moseley, corresponding to this.

Tristan da Cunha.— Endemic. Thouars; Carmichael. 



This species, which is closely allied to Lycopodium clavatum, is remarkable for the 

 long tails to the leaves and bracts.
