144 DE. HOOKER AND DR. THOMSON'S PR.ECTJRSORES 



ramis brevibus divaricatis prostratis, floribus albis, pedicellis calycibus 

 siliquisque glandulosis, siliquis suberectis lincaribus obtusis (1" long., 

 2^" lat.), valvis concavis subenervibus. 

 Hub. In Sikkim regione interioie alpina, alt. 14000-16000 ped. ! J. D. H. 



(fl. Jun.) (v.v.) 

 Distr. Soongaria ! 



A very distinct little species, rather fleshy, with something of the foliage 

 of Senebiera ; easily recognized by the glandular hairs on the foliage and 

 stems, and the glands of the inflorescence and pods. The seeds are young ; 

 but the radicle is manifestly accumbent. 



In Dr. Thomson's and in Mr. Winterbottom's Tibetan and N.W. Hima- 

 layan collections are many specimens of Crucifercc that may be referable 

 to species of Arabis, but which, being without ripe fruit, cannot be distin- 

 guished generically from Sisymbrium. Some resemble closely Persian and 

 Siberian species.
