Note on Polygala. nthe January BULLETIN, p. 32, in not 
ing Dr. Wheelock’s recent paper on Polyga/a (MEMOIRS, Vol. it, 
No. 4) we tried to correct a printer’s blunder in the spelling of ‘ 
P. ovatifolia, A. Gray. What we tried to say and what we now — 
again endeavor to point out is that No. 36, on p. 148, should be 
P. ovatifolia, A. Gray and not P. ovalifolia, A. Gray, as printed. 
The spelling of P. ovalifolia, DC. on p. 149 is uniformly cor 
rect. In the key to the species, both this and P. Californica, — 
No. 33, are correct. 
Reviews of Foreign Literature. 
Revisio Generum Plantarum vascularium omnium atque cellular- — 
zum multarum secundum Leges Nomenclature internationales, : 
cum Enumeratione Plantarum Exoticarum in Itinere Mundt — 
collectarum. Otto Kuntze. (8vo. 2 volumes, pp. clxvix. 
1011. Leipzig, London, Milan, New York and Paris, 1891). 
In the course of Dr. Kuntze’s extensive travels in all parts of - 
the world since the year 1874, he accumulated a collection of 
plants aggregating 7706 numbers. In the subsequent study of 
this great amount of material, carried on principally in the Her 
baria at Berlin and at Kew, he was confronted with the problem 
of determinating on the system of nomenclature he should adopt — 
for them. He wisely decided to adhere strictly to the principles _ 
of priority laid down by the Paris Congress of botanists, and his _ 
results are now given to the world in the two fine volumes before — 
us. In addition to the elaboration of his own collections, he u- — 
dertook an even more extensive work, and one of very much . 
more general importance. He decided to investigate the status 
of every generic name in use, and to point out the oldest available 
one for every genus recognized by him, visiting for this object 
the most extensive and complete botanical libraries in Europe 
It is interesting to note in this connection that he found the Lr 
brary of the British Museum of Natural History superior t0 all 
others. 3
