not quite half a metre high, but new growth had scarcely com- 

 menced. It is branched and erect. It flowers in July and early 

 August, and ripens its seeds in September. The terminal flowering- 

 spikes-'- are stout, cylindrical, blunt, and yellowish, and may grow 

 to be 10 or even 17 cm. long. The three flowers of the cymes are 

 subequal in size ; and the central one reaches less than two-thirds 

 of the way up the segment. The seed is black and tuberculate. 

 Subgenus Eu-Sahcornia.

In the Index Kewensis, S. arabica Linn. Sp. PI. 3 (1753) and 

 S. anceps Lag. op. cit., are also cited as synonyms of this species. 

 However, S. arabica Linn. herb. (!) is identical with S. arabica 

 Pall. herb. (!), and is Kalidium arabicum ; and S. glauca Stokes 

 (Bot. Mat. Med. i., 8, 1812) would appear to be referable to the 

 same species. A specimen named S. anceps Lag. from Carthagena 

 ("leg. Cadorini ") in herb. (!) C. Bailey would appear to belong 

 to the section AnnucB, since the lateral flowers meet below the 

 central one. 



S. fruticosa, sensu stricto, occurs on salt-marshes through- 

 out the whole of the Mediterranean region, and is often a 

 social plant. Duval-Jouve {op. cit., p. 173) says that specimens 

 were sent to him from Brittany by Mons. J. Lloyd, and from 

 Normandy by Mons. Lebel. However, in J. Lloyd's Flo. de 

 rOuest Fr. (ed. 3, 262, 1876), the northern limit of the species is 

 given as the mouth of the Loire; and I have seen no specimens 

 from any station north of this limit. The floras add South Africa, 

 Polynesia, and America ; but I am not certain that these localities 

 yield the same plant. Plants collected by Major Wolley-Dod in 

 South Africa (in herb. Brit. Mus !) are given varietal names. 



The plant is a tufted dwarf shrub, growing separately in 

 rounded tufts or intermatted as a social plant. " It may attain a 

 height of nearly a metre. The plant is erect, suberect, or ascend- 

 ing. It flowers in September, considerably later therefore than 

 S. glauca ; and perhaps therefore the two species do not hybridize, 

 although it would appear that they frequently grow together. 

 Its seeds ripen in November ; but ripe seeds appear to be very 

 rare in herbarium specimens. The vegetative segments are in 

 general longer than those of S. glauca, and the flowering-spikes 

 shorter. In the lower part of the flowering-spikes, the central

 spikes and not the fruiting-spikes are described.
