EXPLANATION OF PLATES, 



380. Mucuna utilii (Wall, MSS,) the prineipal difference of this 

 species, if indeed a species and M,pruriia consists in the hairs of its 

 leiTumea being oppressed and almost silky not erect rigid and sting- 

 ing. In all other respects they authciently agree the flowers in both 

 are'purple the greater size of this is probably attributable to culti- 

 vation in which state only it is known. _

281. Bupleurum plantagimfoUu7n (R. W.) perennial, erect: stems 

 terate, naked towards the base: leaves congested towards the apex 

 of the stem, remote on the branches, somewhat imbricating at the 

 base, petioled, spathulate, about U nerved, the middle one much 

 lar-er • general umbel with 8-10 rays ; partial with 10-14 flowers: 

 leaflets of the involucre and involucel, 5-6 obovate. cuniate or ob- 

 long, decuvrent on the stem, forming acute angles : fruit, prominent. 

 3y nbbed interstices with single large vittae.
