'Ihe honey, which is scanty, is protected by h.iirs aiul secreted at 

 the base of the lube near 

 tlie smooth ovary, the lube , 



being 4-5 mm. lono-, i mm. 

 wide in the lowest part. The 

 stamens are insertetl on the 

 corolla below the middle. 

 The anthers open inwards 

 lonoitudinally, and pollen is 

 set free before the (lower 

 opens, though in stMiie the 

 stigma is ripe first. The 

 short style (2 mm.) ends in 

 two small roundeil lobes, 

 with ring-like lobes beneath, 

 which are coveretl with warts, 

 rhey are level with the an- 

 thers, and take up the sjiace

 The stamens curve outwards 

 at the top and guide the in- 

 sect's proboscis to the flower 

 centre, so that it pas.ses be- 

 tween the antlu-rs and the 

 stigma. It in a young flower an insect thrusts its proboscis which 

 bears pollen from another flower into it, it cross-poliinalcs it, .uid 

 fresh pollen also adheres to the proboscis. As ])ollen is withdrawn it 

 is finally self-polliniited, a mode which is neces.sary on accoimt of the 

 few insect visits and small flowers, growing amongst corn. It is \ isitcd
