K. Schumann also quotes (I.e.) a specimen collected on the Sibrtnge farm, in 

 Munda, Gaboon, by Soyaux (239), under his Taherncemontana brachypoda. The 

 Kew specimen, so numbered, ha^ lanceolate to lanceolate -oblong, gradually acumin »te 

 leaves, which dry green above and pale yellowish -green below and liave longer 

 petioles. I have no doubt that it U specifically distinct from G. hracht/poda ,- but ag 

 there is only one flower-bud with the specimen at Kew, I must i-onfine myself tj 

 drawing attention to this plant.

 glabrous ; branches fistular, rather slender, pale green. Leaves elliptic
