Tropical American genera, to Dr. Carl Miiller, at Halle. He 
treated them in the same way that Schimper did Mandon’s, giving 
most of them manuscript names, making few or no critical com- 
parisons, and furnishing no descriptions. As far as we know, 
they are still lying in his herbarium unpublished.* 
When we went to Europe, in 1891, 1 again took with me all 
the doubtful species and those supposed to be new, for the sake of 
making further comparisons at Kew with Schimper’s specimens. 
In several cases, as shown in the text, I found that Dr. Miiller was 
mistaken, and that my original determinations were correct; in 
several others I found manuscript names of Schimper’s given to 
Mandon’s specimens which had priority over those of Miiller’s 
given to Dr. Rusby’s specimens. In several other cases the types 
were not at Kew, and the specimens had to be referred to William 
Mitten and Emile Bescherelle for further study. We visited Mr. 
_ Mitten and I showed him and gave him several species, the 
types of which were in his herbarium. He very kindly made the 
comparisons for me, and in several cases shared his specimens 
with me. 
We also took a set of the duplicates for M. Bescherelle, and I 
spent a day with him at the Jardin des Plantes in Paris looking up 
some of Montagne’s types. Ina letter received from him at Kew 
he says: 
« As for the mosses collected in Bolivia by Mandon, I think I 
remember that they were distributed by me in 1869, after the 
death of Mandon, which occurred on the 30th of December, 1866. 
Schimper named them, but did not describe or diagnose them. . 
All of Mandon’s mosses, Bolivian and Madeira, were sent to me 
by M. Cosson to be made up into sets, which were sold for the 
benefit of the widow. I kept one set and the residue, and pro- 
posed publishing at least the list of new species with the numbers 
and localities, in order to save Schimper’s priority in the new dis- 
coveries. Unfortunately, other occupations have prevented my 
- accomplishing this project. It will give me pleasure to share wit 
you my duplicates.” : 
We have to thank M. Bescherelle for a very good set of Man- 
don’s monees and we were also fortunate enough to secure Dr. _ 
Spruce’s own private set of his Musci Amazonici et Andini, 5°
