236 MR. A. W. HILL—REVISION OF 
The species which now follow appear to be a group of closely related forms, with the 
possible exception of JV. dissecta, They all agree, however, in the deeply de lamina, 
which is divided into a large number of segments. Their relationships to one another 
may be represented, to some extent, in a graphic manner, but a fuller discussion will 
be found in the notes on the several species.

Both at Kew and Berlin there are two distinct forms on the sheets bearing the 
name S. borussica, Meyen. The species from the region of Lake Titicaca collected by 
Meyen is the true N. borussica, and is easily recognised by its long free petioles, soft white 
tomentum, and cuneate leaf-lobes. The other species has been named Malvastrum
