Z. Wallisti is one of three new species discovered in 
1873 by Gustav Wallis, when in the employment of Messrs, — 
Veitch as collector in New Grenada, and described by the 
* late Professor Braun of Berlin in the Monthly Proceedings 
of the Berlin Academy of Sciences. By Regel it has 
been transferred to his genus Aulacophyllum, which he 
distinguishes from Zamia by the leaves appearing in 
terminal whorls and not one after the other, and by the 
impressed nerves of the. leaflets, characters which in the 
Genera ‘Plantarum (vol. iii. p. 447) are held to be of no 
account, and which Z. Waillisvi does not conform to. The 
nearest ally of Z. Wallisii is Z. Skinneri, Warsczw., a native : 
of Guatemala, figured at Tab. 5242 of this work, which 
has lanceolate prophylla, sessile leaflets, and. elongate 
brown tomentose cones. . : 
The number of known species of Zamia is uncertain. 
In Regel’s Review of the Cycadacee, published in 1876, 
' there are six of Aulacophyllum, twenty-two of Zamia, and 
one of Microcycas (referable to Zamia), and this is about 
the number estimated in the Genera Plantarum; of these 
sixteen are now in cultivation at Kew.
