pay a visit to the Botanic Garden, which is in the out- 

 skirts of the city. It contains an interesting collection 

 of the wild llowers of Norway ; but in other respects 

 seemed scarcely worthy of a European capital. Christian! a 

 is very hot in the summer months- — Norwegians say it is 

 the hottest town in Europe, — and probably the Botanic 

 Garden is dried up by the month of August, and would 

 be seen to more advantage earlier in the season. On 

 the morning of 11th August we sailed in s.s. "Scotland," 

 Captain Stephensen, with whom I had made the same voyage 

 in 1897. The captain was anxious that we should see 

 Norway in winter, .as well as in summer, and distributed 

 among the passengers a treatise extolling the winter sports 

 and other attractions of the country ; but this is not the 

 place to describe these. Grangemouth was reached on 

 14th August. 



This somewhat sketchy and imperfect narrative of a 

 holiday tour is submitted in the hope that some more 

 learned botanist may be tempted to follow our example 

 by exploring a district of great botanical interest, and 

 may thus be able to furnish the Society with a more 

 exhaustive and authoritative rejjort on the products of 

 the Dovrefjeld than I am able to do. 



Ox Variations in Lycopodium clavatum, Linn., with 



THEIR BEARING ON PhYLOGENY. By B. A. EOBERTSON,

Some years ago, while exploring a wood occupying the 

 nortliern side of an exposed liill on the Craighall estate 

 in the north-east of Perthshire, I came across a luxuriant 

 patch of Lycopodmm clavatum. Careful searching showed 

 that all the plants were in the vegetative phase. Having 

 had occasion to be in the district nearly every year 

 since, I visited the Lycopod station, but always failed to 

 obtain any cones. The great storm of November 1893 

 l>ractically levelled the wood, hardly a tree being left 

 standing. Some years elapsed before the fallen timber 

 was removed and the ground cleared. It has not yet
