Lathy rus pubescens is very closely allied to L. tomentosus, 

 Lamk., a native of S. Brazil and Buenos Ayres, which 

 was figured under this name (pubescens) tab. ^996 of this 

 work-. According to Bentham, I.e., L. tomentosus differs 

 from L. pubescens in being taller, and having broader 

 leaflets and stipules, and fewer, rather smaller flowers; 

 differences which are difficult of recognition in herbarium 

 specimens. A far more marked distinction between these 

 species, as shown by the two plates in this work, is the 

 glaucous blue colouring of tab. 3996 (tomentosus), and the 

 dark green of 7891 (pubescens). Both appear to be very 

 variable plants in the size of the leaflets, and number and 

 size of the flowers and stipules. It is further to be observed, 

 that Mr. Andre describes his plant as having glaucescent 

 foliage.
