what lobed disk below the ovary (Fig. 5 B, D). The hairs 

 which occur at a corresponding height on the swollen part of 

 the filaments (Fig. 5 E) may also serve to protect the honey. 



Some of the antipetalous stamens are often suppressed so 

 that the stamens of the flowers vary in number from five to 

 ten ; and 4-inerous corollas may occur together with 5-merous 

 (Fig. 6 Л, B, C). 



The stamens project beyond the corolla, and are widely 



spreading so that 

 the anthers are at 

 a distance from the 

 stigma (Figs. 5, 6). 

 They are generally 

 bent downwards 

 towards the front 

 or lower side of 

 the flower. The 

 stamens have no 

 appendages or 

 other projections, 

 but dehisce at the 

 apex by two large 

 pores (Figs. 5, 6). 



The ovary is 

 covered by peltate 

 glandular hairs as 

 is also the case with the leaves (Figs. 4, 5, B); evidently 

 because assimilation takes place in it as in the latter. Generally 

 the style is so long that the stigma stands at the same level 

 as the anthers and cannot touch the latter when they bend 

 inwards towards it (Fig. 5). But it may also happen that the 

 stamens are half the length of the pistil (Fig. 6 L). 



At Godhavn I found flowers, the stamens of which were 

 short and appeared to have smaller anthers which could scarcely
