1 78 Bog-Trotting for OrcHids 



Habenarias is unique. The anther is eager to give up 

 its pollinia. The adhesive masses shot from their cells 

 when I touched them, and fastened to the head of my 

 hat-pin. When placed near the viscid surface of the 

 stigma, they were drawn forcefully from it, thus im-

On my next excursion to the Bogs of Etchowog, I 

 found nothing new, save six spikes of the Small Purple- 

 Fringed Orchis in bud. I was too early for Pogonias 

 and I^imodorums, which are fast disappearing from 

 this swamp. The colony of Fragrant Yellow Moccasin- 

 Flowers, in the Glen of Comus, was photographed one 

 morning while the sunshine struggled in through the 

 leaves, lighting up the flowers in this labyrinth of 

 tropical foliage. They were fragrant in the highest 

 degree — a true form of Cypripedium parviflorum, with 

 a slight variegated effect of carmine coloring on the 

 tips of the slippers. This is the first instance of such 

 spots of crimson on the exterior observed by me. Near 

 this group stands also a larger colony of Cypripedium 

 hirsutum seedling plants. Several had bloomed this 

 season. One slipper had been destroyed by what ap- 

 peared to be a snail. Nothing of the flower remained 

 but the column, with the adhering anthers and stig- 

 matic lobes. The sepals and petals, including the 

 labellum, were eaten away. The snail was still cling- 

 ing to the column, and must have found some delicate
