CACTUS. 229 
30 to 40 centimeters when full grown. The cephalium has a diameter of about 8 cm. anda height of 
3 inches and is formed by clusters of short spines strongly set together and which are of a reddish hue. 
In the middle of the clusters beautiful flowers sprout out and are followed by purplish fruit that give 
the whole plant a fair and elegant aspect. This Melocactus is found in the fissures of lofty, perpen- 
dicular mountain passes, but in very limited numbers, and in a region not exceeding a square mile 
in extent. Therefore it is impossible for me to collect large numbers of the same. 
‘‘Cactus lovers have now an opportunity to enrich their collections with this new specimen which 
has already excited the cordial admiration of amateurs both in the United States and Germany.”’ 
We wrote to Mr. S. A. Skan, of the Kew Library, regarding this publication and name 
and he replied as follows: 
““T have made an effort to ascertain the date of its publication but regret that I have not 
obtained any definite information. The name Melocactus salvador has not been taken up in any of the 
supplements to the Index Kewensis. In the Kew Hand-List of Tender Dicotyledons (1899) there is 
*M [elocactus] salvatoris, Hort. Mexico.’ I supposed that to be a mistake for M. salvador and com- 
municated with Mr. Watson aboutit. He tells me that a plant named M. salvatoris was purchased 
from Prof. L. Murillo in 1898. It is not now at Kew.”

It must be different from Melocactus curvispinus (Pfeiffer, Enum. Cact. 46. 1837) also 
from Mexico, a species which we know only from description. It is described as globose, 10 
cm. high, 7.5 cm. in diameter, depressed; ribs 10 to 12; areoles large, round, white-velvety ; 
radial spines 7, curved, brownish or white, 12 to 16 mm. long; central spines 2, erect, 2.5 cm. 
long, blackish. 
Another species, Melocactus delessertianus Lemaire (Hort. Univ. 1: 225. I 839), has been 
described from Mexico which may or may not be this plant. It was described as slightly 
depressed, about 10 cm. high; ribs 12 to 15; radial spines 8 or 9; central spines 2; flowers and 
fruit unknown. _

the Library at Kew, a copy of which was sent us by the Director, Captain Arthur W. Hill.
