Flora of St. Croix. 
I HAVE, quite by chance, just come across The flora of the island of St. 
Croix, published by C. F. Millspaugh in the Feld Columbian Museum Bot. 
Series, Vol. I, no. 7, which was issued at the end of last year. In Mr. Mills- 
paugh’s work no notice whatever is taken of the species published by Mr. 
Paulsen and the writer in a floristic appendix to our work “Om Vegetationen 
paa de dansk-vestindiske Oer;” though Mr. Millspaugh in his introduction 
gives a complete ponee leone of the lines from Urban’s “ Bibliographia” 
dealing with our work: n a floristic appendix six phanerogams new to ves 
Danish islands and Rosccay’ s fungi and lichens are listed.” 
We are thus led to believe that the author has not taken the trouble to 
read our paper.'. Nor has he apparently made himself acquainted with the 
additions to Urban’s “ Bibliographia,” which occur in later numbers of the 
Symbolae Antillanae. The result is that none of the species of phanero- 
gams, fungi, and lichens published by us have been included. The author 
also gives a short list of algae, containing, according to his typography, spe- 
cies new to the island. But hardly any of them are really new, as almost all 
of them, and several others, are mentioned in my short paper, ‘‘A contribu- 
tion to the knowledge of the marine algal vegetation of the coasts of the 
Danish West-Indian islands.” I have, moreover, distributed some St. Croix 
algae in Wittrock and Nordstedt’s exsiccatae, and in Phycotheca Amer.-bor. 
t is of course of great interest to have the new finds in St. Croix pub- 
islands. But when Mr. Millspaugh sets out to give a complete list, we are 
justified in expecting that everything published regarding the flora of the 
islands will be included.— F, BORGESEN. 
Ir 1s distinctly stated on page 459 of the publication referred to that it 
only includes the work of the Rickseckers, checked by the only published 
general list of the island flora, viz., Eggers’s. It was not the intention to 
include scattered lists. All of Urban’s publications which were available up 
to the date of sending in copy were made use of.— C. F. MILLSPAUGH.
