The entertainments, excursions, and visits to various institutions were 
humerous and attractive. A reception by the emperor was arranged, but 
the death of Grand Duke Josef on Tuesday estopped that, as well as a 
reception by the burgomeister at the Rathaus. Various long excursions 
after the Congress were provided, and all were sufficiently patronized to be 
undertaken. 
The Committee of organization and the various local committees are 
to be congratulated on the success of their arrangements. These quin- 
quennial international Congresses may now be considered a fixed feature 
of the botanical world.—C. R. B 
ANOTHER SEED-LIKE CHARACTERISTIC OF SELAGINELLA. 
Two sprctes of Selaginella (S. rupestris and S. apus) form embryos 
in the autumn which may resume growth after a period of rest. I left 
plants of these two species in a shallow box out of doors during the months 
of November and December, 1903. They were frozen and thawed several 
times during that time. In January the box was brought into the labora- 
tory, the plants watered thoroughly, and allowed to thaw gradually. At 
the expiration of three or four days, the vegetative parts of the plants 
indicated a resumption of growth. Upon examining the strobili, young 
sporophytes were found thrusting roots and cotyledons from the female 
gametophytes. Selaginella rupestris is the species which displays a reduc- 
fon in the number of Megaspores, which are retained throughout germina- 
on, and even until the young sporophyte is well advanced.—FLORENCE
