At first sight anyone might think that A. armentum and HZ. 
glanduliferum were two different species; but the numerous 
plants referred to H. armenium by Boissier show such a variation 
that we understand very well why he considered the whole lot as a 
polymorphic but unique species. 
However, as may be seen by the description, this particular form, 
called glanduliferum by Schultz seems so well characterized by 
its glands and the form of leaves and indumentum, that it is prac- 
tical to keep it apart as a variety. The specimen of the New York 
Herbarium is absolutely identical with the form of Schultz. 
The type of A. armenium DC. is Guaphalium armenium 
Fisch. et Mey., founded upon a plant of Szowitz, a specimen of 
which is in Herb. Boissier. From that plant I took the indications 
concerning the forma tyfica of the species.

L. helianthifolia differs certainly from ZL. /atzfola DC. as may 
be seen in the originals. The leaves of Z. latifolia DC. are sca- 
brous beneath, while those of eldanthifolza are softly tomentose. 
On the other hand Z. latifolia = L. suaveolens H.B.K.; DC., 
therefore it is an error to consider Z. suaveolens and L. helt- 
anthifolia as synonyms, as English authors do, for instance in
