At Stockholm, the black-tiled brick buildings of the Natural 
History Museum and the Academy of Natural Sciences are 
architecturally attractive and the herbarium collections are ex- 
ceptionally interesting, since they include an enormous assemblage 
of specimens from southern and eastern Brazil and from the 
mountains of East Africa, as well as a number of important 18th 
Century collections from America. Dr.Samuelsson, an authority 
on aquatic plants of northern Europe, was most helpful to me in 
locating important specimens of sedges. I also had the pleasure 
of meeting Dr. Hultén, of Lund University, who was visiting 
Stockholm; he is well known for his work on the plants of Kamt- 
chatka, and is now describing the vegetation of Alaska. Just 
across the road from the museums is the botanic garden (Hortus 
Bergianus), founded in the 18th Century, by Bergius, a pupil of 
Linnaeus, and well known for the clipped hedges of ancient beech 
trees, and for the towering rock garden, exhibiting primarily the 
plants of western China. 
North of Stockholm, an hour’s ride by railway, lies the old 
university town of Uppsala. Here, in addition to the splendid 
cathedral and the completely restored Linnaean Garden, may be 
seen the botanic gardens which were started by Rudbeck in 1655, 
and which surrounded the botanical buildings of the university.

ants are still present which were probably grown two 
hundred years ago by Linnaeus from seeds obtained in eastern 
America; among them I especially noted the purple Joe-Pye 
Weed (Eupatorium purpureum), which exists here in the type- 
form (Eupatorium trifoliatum) characteristic of the southern 
Alleghenies. 
Proceeding to Berlin by way of the Trelleborg Ferry and the 
island of Rugen with its high chalk cliffs, I spent some time at the 
Royal Botanic Gardens and in the extensive herbarium which 
contains the Willdenow collection, including the types of many 
species described from Pennsylvania. Tome the most impressive 
things in the Garden were the beautiful Vzctoria regia house, with 
its gigantic-leaved water-lilies in full bloom, and the rock garden 
with its replicas of geological formations with their associated 
plants, illustrating the various botanical regions of the Alps and 
Carpathians, a type of exhibition which does not seem to be ap-
