Perv, Cuur: Tacora, 4200 m., Stábel, 108 ii. (Herb. Berol.). 
Stübel collected several specimens*, now in the Berlin Herbarium, under the 
numbers 5 and 108, either on the mountains of Sajama in Bolivia or Tacora on the 
boundaries of Chili and Peru. They are in five separate packets on the Herbarium 
sheets, which I have distinguished as no. 5 i. ii. and iii., and no. 108 i. and ii. All 
these specimens were referred by Hieronymus to his new species M. sajamense, but 
a careful examination of the material showed that at least four different species were 
included in the different packets. W. sajamensis is the most frequent and packets 5 
i., ii. in part, iiL, and 108 i. in part, are occupied by this species. The packet 108 ii. 
contains the new species W. alternata, so named from the regular alternations of whorls 
of vegetative and flower-bearing leaves on the stems; packet 5 i. in part contained 
specimens of N. obcuneata, whilst packet 108 i. in part (part A) contains specimens which 
are apparently identical with the species named M. Meyeni by Count Solms t. "Though 
Stübel's material appears to have been carelessly collected, it is nevertheless of interest to 
learn from it that these four distinct species all grow in close contiguity. 
The plants of N. alternata show a certain external similarity to JN. sajamensis, 
N. Meyeni, and N. turritella. In the latter species there is also a similarly whorled 
arrangement of the leaves: those which bear the flowers only occur apparently at regular 
—perhaps annual—intervals, and are separated from each other by a whorl of sterile 
leaves. 
In N. alternata the distinction between petiole and lamina is not easy to determine; 
the petiole is dilated to form a broad flattened cuneate expansion bearing the short lobes 
of the lamina at its apex. The large woody carpels found in this species are also 
remarkable: they are twice as large as those of N. turritella and also differ from them 
in their longer beaks. It is unfortunate that ripe fruits of neither N. sajamensis nor 
N. Meyeni have been collected,
