Hai.i.uodendron. Salt Tree. 

 (Family Leguminosae). 



Shrubs with more or less pun- 

 gent stipules and frequent per- 

 sistent spine-tipped leaf-axes, oth- 

 erwise deciduous. Twigs slender 

 or often forming globose spurs 

 invested by the many persistent 

 bud scales, angular: pith rather 

 small, somewhat angular, contin- 

 uous. Buds usually thicker than 

 the twig, solitary, sessile, globose, 

 with some half-dozen exposed 

 acute scales. Leaf-scars alternate, 

 much raised, minute: bundle-trace 

 1: stipules erect beside the bud, 

 on the leaf-cushion. 



Halimodendron differs from 

 other commonly seen plants with 

 a much raised persistent leaf-base 

 in that this spreads almost hori- 

 zontally from the stem, in this 

 way making place for the globose 

 These frequently develop into short 

 leafy spurs, on the leaf-bases of which spines sometimes per- 

 sist. As in Parkinsonia and Caragana, the spines are per- 

 sistent axes, marked with scars from which leaflets have 

 fallen. The winter-characters of H. halodendron are pictured 

 by Schneider, f. 72. 



relatively large buds. 



Outer bud-scales dark, the inner pale.
