the West Indies to continental tropical America. In the collec- 
tion will be found plants of Zanua pumila and Zamia floridana, 
known as ‘‘coontie,” both found extensively in certain parts of 
Florida ; at one time considerable starch was manufactured from 
the underground parts of these plants. A number of other species 
will also be found in the collection. 
Dioon now includes three species, all from Mexico: the old 
and well-known Dioon edule, the more recently described Dioox 
spinulosum, and Dioon Purpusii, brought to the attention of 
scientists the present year by Dr. J. N. Rose, of the United 
tates National Museum. The plant on exhibition in the Garden 
collection was secured by him, in conjunction with Dr. D. 
MacDougal, in Tomellin Cafion, Oaxaca, in 1906. It is one of 
the choice plants of the collection. 
The genus Ceratozantia, also Mexican and containing at pres- 
ent about six species, is represented by two ses Ceratozanua 
mexicana and Ceratozamia ie la the former by two large 
specimens, the latter one. The Secon ie which 
means “horned Zamia,” was given to fee plants on account of 
the two sents which are found on each of the cone-scales. 
While the cycad collection of the Garden contains many inter- 
esting and unusual plants, there are still many species which are 
without representation, and it is very desirable that these be 
secured. e present quarters of the family will accommodate 
many more plants, and it is hoped that other species, not now in 
the collection, may be obtained by gift or exchange.
