The drawing I made of this plant, together with my notes, 
were lost ; but I owe to the kindness of M. Decaisne a loose 
leaflet and raceme, which have enabled me to make out the above 
diagnosis; the leaflet is 3i inches long, 1;^ inch broad, with an 
attenuated apex 3 lines long, 1^ line broad; it is inequilateral 
at base, and fixed on a petiolule 1 line long ; it has six diagonal 
nervures on each side, 3-5 lines long, arching together, quite 
sunk in the pai’enchyma, and sulcated equally on both sides ; 
the racemes, four out of each axil, are quite smooth, 2-3 inches 
long ; the pedicels are 1-2 lines long, bracteated at base, bear- 
ing a globular flower in bud, 1 line diam.

lanceolatis, acuminatis, basi in petiolum attenuatis, subaveniis,

3. Burasaia congesta, Dene. loc. cit. ; — ramulis crassiusculis, te- 
retibus, cortice Isevi, cinerascente : foliis mediocriter petiolatis, 
3-foliolatis ; foliolis oblongis vel lanceolatis, apice brevissime 
et repente attenuatis, acumine obtuso, imo subacutis, latera- 
libus oblique inaequalibus, terminali majore, subcoriaceis, 
utrinque nitidis et glaberrimis ; supra impresso-punctulatis, 
nervis pinnatis immersis; subtus pallidioribus, nervis teneribus 
vix prominulis : petiolo valde compresso, nitido ; petiolulis 
brevissimis, canaliculatis : racemis simplicibus, 3-4, in axillis 
fasciculatis, folio brevioribus ; floribus sparsis, breviter pedi- 
cellatis. — Madagascar, v. s. in hei'b. Mus. Brit. ; “ Amboura-

The above specimen, though not in good condition, agrees 
sufficiently with the diagnosis of Prof. Decaisne, and has enabled 
me to amplify its characters. The branch, covered with a smooth 
grey bark, is I inch diam., with internodes of inch; the 
terminal leaflets, always larger, are 3^-4^ inches long, If- 
If inch broad, on a petiolule 3 lines long; the lateral leaflets 
are 2|-3 inches long, i^ch broad, on petiolules 2 lines long ; 
the racemes have a slender compressed glabrous rachis, about
