at the apex of the two tubes into which the anthers are 

 prolonged lie immediately below the stigma which protrudes 

 somewhat further. The pale brown anthers are slightly rough 

 (Fig. 28 E, F) ; on their dorsal side they have moreover two 

 upwardly curving rough appendages which stand at about the 

 middle of the corolla.

л, Open flower. B, Longitudinal section through flower; there are ah'eady many pollen 

 tetrads (C) upon the stigma (D). E, F, Anthers of B. 0, If, In this bud the anthers are 

 open, and the pollen falls easily out of them when they are dry, but pollen has not yet 

 been shed upon the stigma; on the latter two small drops (J) have been secreted. K, A 

 flower the corolla of which has been split by insects (Stockholm), i, Apical portion of 

 a branch with the uppermost lateral bud ; to the right the scar left by the subtending leaf.

The flower is protandrous for a very short time and then 

 homogamous (this agrees with the statement of Lindman, Ekstam 

 and H. Müller; according to Alli the plant is slightly protogy- 

 nous). The anthers open while still in the bud (Fig. 28 (r, Л), 

 and the pollen falls easily out of them as soon as they are 

 dry. At any rate the stigma ripens immediately after the flower 

 has expanded, but even in the bud I have seen drops secreted 

 upon it (Fig. 28 J).
