Mlanje District: Mlanje Mountain, 2700 m., March, 1897, Adamson 351; Lu- 

 chenya Plateau, rocky situations in grassland, shrub about 1 m. high, flowers 

 greenish, 2000 m., July 3, 1946, 16656 (TYPUS in Herb. Kew.). 



The sharply cuspidate, petiolulate leaflets place this species near R. chirm- 

 densis Bak. f. and R, legati Schonl., but these are both large shrubs or small 

 trees, with leaflets lacking the elegant reticulate venation which is such an ob- 

 vious feature in dried material of R. monticola. The species would appear to be 

 endemic to Mlanje Mountain.
