EARLY INVESTIGATIONS OF NORTH AMERICAN FLORA

fessor Kalm, equipped by nature to search for plants, collected 
an incredible multitude thereof in North America, and gave me 
of each a specimen.» These specimens are to be found in Lin¬ 
naeus' herbarium now in the care of the Linnaean Society of 
London, and constitute the types of the species founded on Kal- 
mian specimens. The collection which Kalm retained for himself 
was probably lost in the fire at Åbo in 1827. But another 
collection of Ivalm’s N. American plants still exists and is now 
kept in the Botanical Museum of the University of Upsala. 
In his Egenh. anteckn. (p. 50) Linnaeus says under the 
year 1751: »Her Majesty the Queen takes pleasure in Natural 
History and procures the most splendid collections of Conchylia 
and Insecta from India, so that they rivalled with the largest in 
the world. Linnaeus is ordered to come to Drottningholm, in 
order to describe all this. » Later the Queen also added a her¬ 
barium to her museum. To help her with this she had Erik 
Tuwen, later actuary in the Collegium Medicum, whom Linnaeus 
in his letters to Baeck calls »adglutinator regius» and »exsic¬ 
cator Regius» (Bref och skrifvelser af och till Carl von Linné, 
I: 4, Stockh. 1910, p. 292, 295, 335). That Linnaeus himself 
also worked in some way with this herbarium, can be seen from 
this passage in a letter (Sept. 1 754) to Baeck: »Cum jussus eram 
in ordinem disponere plantas Reginse, ut posset alterum exemplar 
dare S. Regi, etc.» (Bref etc. I: 4, p. 301). Hasselquist’s col¬ 
lection of plants from Egypt and Palestine (of which I have given 
an account in the 1st volume of this periodical) was purchased 
by the Queen in 1754 and perhaps formed the beginning of her 
herbarium. In the same year it was augmented with a collection 
of Kalm’s N. American plants, which he offered as a present to 
the Queen. (Kalms letters to Linnaeus 8th March and 28th 
Sept. 1754). 
C. P. Thunberg has published a series of dissertations con¬ 
taining catalogues of the Museum of natural history belonging 
to the University of Upsala. In one of these we find the fol¬ 
lowing passage: »a really royal gift came to the Academy (uni¬ 
versity) from the Museum of Drottningholm. Queen Lovisa
