Only one specimen of this was gathered, but fortunately it 
was in fruit, The ripe fruits were previously unknown. 
Distribution. Nightingale and Inaccessible Islands. 
SPARTINA ARUNDINACEA, Carmich. in Trans. Linn. Soe. Lond.

Bot. i. 11. p. 160, t. 25. 
Ponceletia arundinacea, Thou. Esq. FL Trist. p. 86. 
This is one of the predominant plants of the island, ap- 
parently growing luxuriantly everywhere up to an elevation 
of over 1000 feet. 
Distribution. Tristan da Cunha, Inaccessible and Nightingale 
Islands, and St. Paul and Amsterdam Islands. 
Poa annua, Linn. Sp. Pl. p. 68. 
A few plants of this were found near the ruined huts of some 
sealers. It is no doubt introduced as it is on Tristan da Cunha. 
Distribution. Very widely spread.

ADIANTUM JETHIOPICUM, Linn. Sp. Pl. ed. rr. p. 1560; Thou.

Very plentiful in the glen. 
This is a very variable plant, and the Gough Island plant 
shows several varieties. Until a satisfaetory monograph of the 
genus appears, it seems preferable to inelude all the Gough 
Island specimens under the name of Adiantum cthiopicum. 
Distribution. Tristan da Cunha and Inaecessible Island ; 
Central and South America (except the extreme south), South 
Africa, India, and New Zealand.
