92 The Ottawa Naturalist. [Oct. 



All species of Antennaria in Greenland produce well devel- 

 oped fruits having the power of germination. As staminate 

 flowers are totally wanting, the propagation of all species must 

 be apogamic, as for a long time such has been known to be the 

 case with A . alpina . The /I . glabrata and .4 . intermedia, as they are 

 growing near m}' home, are without doubt hereditary constant. 

 They often form extended pure patches, the form of which 

 depends on the circumstances of local wind or the outlet of 

 melting water in the spring. 



If my understanding of the species be right, A. alpina 

 must be regarded as an old species that found its way to Green- 

 land after the glacial period, probably over Smith Sound, 

 where the crossing may have taken place during an epoch with 

 milder climate than now rules in Greenland. A. groenlandica, 

 however, belongs to the large contingent of American plants of 

 South Greenland, 'that cannot have immigrated by this way. 

 A. glabrata and ^4. intermedia are imdoubtedly young spec es, 

 or perhaps species in statu nascendi, the former developed from 

 A. alpina, the second from .4. groenlandica. 



We have thus in the Greenland species of Antennaria a 

 new example of polymorphy in apogamic genera (cfr. Alchi- 

 milla. Taraxacum, Hieracium).

EXCURSIONS. 



The third excursion of the season was held at Britannia, 

 on the afternoon of Saturday, May 16th. The party walked 

 to a wooded grove, and the time was mostly engaged in botanical 

 observations. At the addresses leaders spoke of the plants, 

 birds, insects, and batrachians observed or collected, and infor- 

 mation along general lines of natural history was imparted. 



The fourth excursion was held at Fairy Lake. This was on 

 the afternoon of Saturday, May 23rd. After leaving the electric 

 cars, the party walked for a distance, until this ideal spot, known 

 as Fairy Lake, was reached. The excursion was of the nature of 

 a saunter, and the usual addresses were purposely dispensed 

 with, this leisurely walk homewards through the woods of the 

 Beaver Meadow taking for this occasion their place.
