Dawe, 350, has (in the single flower examined) five additional 

 stamens, the three upper whorls being normal, and the lowest 

 being replaced by eight solitary stamens and one pair arranged in 

 two irregular whorls, thus bringing the total number of stamens 

 to 40. Linton, 65, has practically the same staminal column. 

 Linton, 32, has 45 stamens, in five whorls, of which the four 

 upper consist of five pairs each, and the lowermost of five solitary 

 stamens which alternate with the petals. In Smith, Kilimanjaro, 

 on the other hand, the stamens are reduced in one flower to 30, 

 and in another to 32, by the suppression respectively of all five 

 and of three of the stamens of the lowermost whorl. All the other 

 specimens quoted exhibit the typical arrangement of the staminal 

 column. 



Linton, 40, has abnormally large flower-: calyx-lobes 11-12 

 mm. long ; petals nearly 2 cm. long, 11-12 mm. broad ; staminal 

 column 17 mm. long, the lowest whorl of stamens inserted 5 mm. 

 above the petals ; joint style 12 mm., branches 4 5 mm. long. 



H. aponeurus is intermediate between H. crassinervius and 

 H. Hildebrandtii, having the staminal column of the former, and 

 bracteoles and calyx approaching those of the latter. In H. crassi- 

 nerviiis the calyx lobes are three-nerved, and the lateral nerves of 

 adjacent lobes unite just below the sinus and run down the 

 calyx-tube as a single nerve, so that the tube is ten-nerved ; in 

 H. aponeurus the calyx lobes are likewise three-nerved, but often 

 with an indication of* two additional submarginal nerves, and the 

 lateral nerves run down the calyx-tube parallel or approximating, 

 only in rare instances uniting before reaching the base, so that 

 the tube is fifteen-nerved.
