CONVOLVULACE2E. 

 Convolvulus soldanella ? Linn. 



Convolvulus soldanella? Linn.,Sp. PI., ed. 1, p. 159 ; Carniich. in Trans. Linn. Soc. Lond, xii. p. 505. 

 Tristan da Cunha. Carmichael. 



This plant is widely spread on the sea-shores in the north and south temperate zones, 

 and is not an unlikely one to have reached the islands. Unfortunately we have not 

 succeeded in finding Carniichael's specimen in the Herbarium of the British Museum, 

 where the first set of his collection is deposited. Carmichael states that he found it on the 

 southeast side of the island growing in the sand close to the shore, and confined to a 

 single spot. He regarded it as of recent introduction, " having in all likelihood been 

 wafted to this shore by the current." It is, however, in none of the subsequent collections ; 

 but MacGillivray and Milne collected the almost equally widely dispersed allied species, 

 Convolvulus sepium, Linn. (Cali/stcgia sepium, E. Br.) in the island of St Paul, in great 

 abundance, about fifty yards from the shore. 



Moseley mentions (Journ. Linn. Soc. Loud., xiv. p. 380) that a Convolvulus was very 

 abundant on cultivated ground near the huts of some Germans on Inaccessible Island. 

 He assumed that it was introduced by them, and brought away no specimen. 



CHENOPODIACEzE. 



Chenopoclium tomentosum, Thouars. (Plate XXVIII.) 



Chenopodium tomentosum, Thouars, Esqirisse Fl. Trist., p. 38; Carniich. in Trans. Linn. Soc. Lond., 



xii. p. 505; DC, Prodr., xiii. 2, p. 7-1. 

 Ambrina tomentosa, Moq., Chenop. Monogr. Enuni., p. 37. 



Tristan da Cunha, Inaccessible, and Nightingale Islands. Thouars; Carmichael; 

 Milne and MacGillivray ; Mosdeij. Abundant. 



This plant appears to be restricted to the Tristan da Cunha group. Moseley collected 

 it in all three islands. Milne and MacGillivray note on their labels that it was common 

 all over Tristan da Cunha, where it was used as tea ; and this use is still kept up. 



Atriplex plebeja, Carmich. (Plate XXIX.) 



Atriplex plebeja, Carrnieh. in Trans. Linn. Soc. Lond., xii. p. 508; DC, Prodr., xiii. 2, p. 101. 



Tristan da Cunha. — Endemic? Carmichael. 



We have only seen the specimen collected by Carmichael, and he states that the 

 plant grew along the shore, and seemed to be almost a stranger in the island. Probably 

 an introduced plant, though we have not succeeded in identifying it. The fruit is 

 unknown.
