Halocnemum strobilaceum (Pall.) M. B. 



A stumpy, often decumbent shrub which grows on clayey 

 soil rich in salts. 



The year-shoot has a thick bark containing aqueous 

 tissue and green tissue, and is covered with opposite, reduced 

 leaves, united in pairs to form a sheath. Almost every axil 

 on a year-shoot is occupied by a branch or short-shoot 

 shaped like a more or less elongated bud or a short catkin. 

 An illustration of a branch is given by VOLKKNS in Nat. 

 Pflanzenfamilien III (Chenopodiaceae) fig. 35. In fig. 43 is

represented a longitudinal section of part of such a short- 

 shoot. As stated by WARMING (1897, p. 206), the leaves are 

 somewhat peltate. Sometimes they support three buds (B. 

 fig. 43), which are presumably flower-buds as the leaves on 

 many short-shoots each subtend a triplet of flowers in the 

 autumn. The flowering short-shoots die after the ripening of 

 the fruits, and along with the distal part of the year-shoot 

 drop off before the next vegetative period. 



Beyond the dead short -shoots, new shoots are formed 

 next year, often several together, either elongated year-shoots 

 or new short-shoots. 



The anatomy of the leaf has been described by WARMING
